The delete action of the eraser tool is controlled by the general option setting for deletion. Before using the eraser tool, be sure that you understand the available options described in Section 3. To activate the eraser tool from the keyboard, use the D key. The layer tool is the rectangular icon with a capital L in the lower left corner.

Use the layer tool to organize the objects on an EER Diagram canvas. It is useful for grouping similar objects. For example, you may use it to group all your views. Click the layer tool and use it to draw a rectangle on the canvas. Change to the standard mouse pointer tool and pick up any objects you would like to place on the newly created layer. To change the size of a layer, first select it by clicking it. When a layer is selected, small rectangles appear at each corner and in the middle of each side.

Adjust the size by dragging any of these rectangles. You can also make changes to a layer by selecting the layer and changing properties in the Properties panel. Using the Properties panel is the only way to change the name of a layer.

To activate the layer tool from the keyboard, use the L key. For more information about layers, see Section 9. The text tool is the square icon with a capital N in the top left corner. Use this tool to place text objects on the EER diagram canvas.

Click the tool, then click the desired location on the canvas. After a text object has been dropped on the canvas, the mouse pointer reverts to its default. To add text to a text object, right-click the text object and choose Edit Note You can manipulate the properties of a text object by selecting it and then changing its properties in the Properties panel. To activate the text tool from the keyboard, use the N key.

For more information about text objects, see Section 9. Use the image tool to place an image on the canvas. When this tool is selected and you click the canvas, a dialog box opens enabling you to select the desired graphic file. To activate the image tool from the keyboard, use the I key. For more information about images, see Section 9. Clicking the canvas creates a table. You can also double-click the table to load it into the table editor.

To activate the table tool from the keyboard, use the T key. For more information about creating and editing tables, see Section 8. Use this tool to create a view on an EER Diagram canvas. When the table tool is activated, a schema list appears on the toolbar below the main menu, enabling you to associate the new view with a specific schema.

You can also select a color for the object by choosing from the color list to the right of the schema list. After selecting this tool, clicking the canvas creates a new view. To edit this view, right-click it and choose Edit View To activate the view tool from the keyboard, use the V key. For more information about creating and editing views, see Section 9.

Use this tool to create a routine group on the EER Diagram canvas. When this tool is activated, a schema list appears on the toolbar below the main menu, enabling you to associate the routine group with a specific schema. You can also select a color for the routine group by choosing from the color list to the right of the schema list. After selecting this tool, clicking the canvas creates a new group.

To edit this view, right-click it and choose Edit Routine Group To activate the routine group tool from the keyboard, use the G key. For more information about creating and editing routine groups, see Section 9. These tools appear at the bottom of the vertical tool bar. Hover the mouse pointer over each tool to see a text hint that describes its function. For more information about relationships, see Section 9.

If a table with this name already exists, the new table is named table2. Adding a new table automatically opens the table editor docked at the bottom of the application. For information about using the table editor, see Section 8. The Paste option is also accessable from the main Edit menu.

Edit Table Edit in New Tab Copy Column Names to Clipboard : Copies a comma-separated list of column names. Nothing is copied to the clipboard if the table has no inserts defined. If the table editor is not open, the Edit Table If it is already open, the selected table replaces the previous one.

Any tables added to the Physical Schemata section also show up in the Catalog palette on the right side of the application. They may be added to an EER Diagram by dragging and dropping them from this palette. Tables can also be added to an EER Diagram using the table tool on the vertical toolbar. Make sure that the EER Diagram tab is selected, then right-click the table icon on the vertical toolbar.

The table icon is the rectangular tabular icon. Clicking the mouse on this icon changes the mouse pointer to a table pointer. You can also change the mouse pointer to a table pointer by pressing the T key. Choosing the table tool changes the contents of the toolbar that appears immediately below the menu bar.

When the Tables pointer is active, this toolbar contains a schemata list, an engines list, a collations list, and a color chart list. Use these lists to select the appropriate schema, engine, collation, and color accent for the new table. Make sure that you associate the new table with a database. The engine and collation of a table can be changed using the table editor.

The color of your table can be changed using the Properties palette. The Default Engine and Default Collation values refer to the database defaults. Create a table by clicking anywhere on the EER Diagram canvas. This creates a new table with the default name table1. To revert to the default mouse pointer, click the arrow icon at the top of the vertical toolbar.

As shown in the preceding diagram, the primary key is indicated by a key icon and indexed fields are indicated by a different colored diamond icon. Click the arrow to the right of the table name to toggle the display of the fields. Toggle the display of indexes and triggers in the same way. With the exception of the deletion item, these menu items function as described in Section 9. For more information, see Section 3. Foreign key constraints are supported for the InnoDB storage engine only.

For other storage engines, the foreign key syntax is correctly parsed but not implemented. For more information, see Foreign Key Differences. This section deals with adding a foreign key using the foreign key tools. To add a foreign key using the table editor, see Section 8. The graphical tools for adding foreign keys are most effective when you are building tables from the ground up.

If you have imported a database using an SQL script and need not add columns to your tables, you may find it more effective to define foreign keys using the table editor. An identifying relationship : identified by a solid line between tables. An identifying relationship is one where the child table cannot be uniquely identified without its parent. Typically this occurs where an intermediary table is created to resolve a many-to-many relationship.

In such cases, the primary key is usually a composite key made up of the primary keys from the two original tables. A non-identifying relationship : identified by a broken dashed line between tables. Create or drag and drop the tables that you wish to connect. Click on the appropriate tool for the type of relationship you wish to create. This creates a column in the table on the many side of the relationship. When the many-to-many tool is active, double-clicking a table creates an associative table with a many-to-many relationship.

For this tool to function there must be a primary key defined in the initial table. Use the Model menu, Menu Options menu item to set a project-specific default name for the foreign key column see Section 9.

To change the global default, see Section 3. To edit the properties of a foreign key, double-click anywhere on the connection line that joins the two tables. This opens the relationship editor. Mousing over a relationship connector highlights the connector and the related keys as shown in the following figure. After mousing over a relationship for a second, a yellow box is displayed that provides additional information.

If the placement of a connection's caption is not suitable, you can change its position by dragging it to a different location. If you have set a secondary caption, its position can also be changed. For more information about secondary captions, see Section 9. Where the notation style permits, Classic for example, the cardinality indicators can also be repositioned. The relationship notation style in Figure 9.

You can select multiple connections by holding down the Control key as you click a connection. This can be useful for highlighting specific relationships on an EER diagram. Double-clicking a relationship on the EER diagram canvas opens the relationship editor. This has two tabs: Relationship , and Foreign Key. In the Relationship tab, you can set the caption of a relationship using the Caption field. This name displays on the canvas and is also the name used for the constraint itself.

Use the Model menu, Menu Options menu item to set a project-specific default name for foreign keys. Fully Visible is the default but you can also choose to hide relationship lines or to use split lines. The split line style is pictured in the following figure. A broken line connector indicates a nonidentifying relationship. The split line style can be used with either an identifying relationship or a nonidentifying relationship. It is used for display purposes only and does not indicate anything about the nature of a relationship.

To set the notation of a relationship use the Model menu, Relationship Notation menu item. The Mandatory check boxes are used to select whether the referencing table and the referenced table are mandatory. By default, both of these constraints are true indicated by the check boxes being checked.

The Cardinality section has a set of radio buttons that enable you to choose whether the relationship is one-to-one or one-to-many. There is also a check box that enables you to specify whether the relationship is an identifying relationship. Right-click a connection to select it. When a connection is selected, it is highlighted and its properties are displayed in the properties palette. Connection properties are different from the properties of other objects.

The following list describes them:. By default, the name is the name of the foreign key and the property is centered above the connection line. By default, this extra caption is centered beneath the connection line. It is just a logical connection drawn on a diagram. This is used, for example, when drawing MyISAM tables with a visual relationship, but with no foreign keys. Note that this is not the name of the foreign key. In most cases, you can change the properties of a relationship using the relationship editor rather than the Properties palette.

If you make a relationship invisible by hiding it using the relationship editor's Visibility Settings , and then close the relationship editor, you will no longer be able to select the relationship to bring up its relationship editor. To make the relationship visible again, you must expand the table object relating to the relationship in the Layers palette and select the relationship object.

To edit the selected object, right-click it, then select Edit Object. You can then set the Visibility Settings to Fully Visible. The relationship will then be visible in the EER Diagram window. The default name of the view is view1. If a view with this name already exists, the new view is named view2. Adding a new view automatically opens the view editor docked at the bottom of the application. For information about using the view editor, see Section 9.

If the table editor is not open, the Edit View The cut and copy items are useful for copying views between different schemata. There will be no confirmation dialog box. Any views added to the Physical Schemata section also show up in the Catalog palette on the left side of the application. Make sure that the EER Diagram tab is selected, then left-click the view icon on the vertical toolbar.

The view icon is the two overlapping rectangles found below the table icon. Clicking this icon changes the mouse pointer to a view pointer. To change the mouse pointer to a view pointer from the keyboard, use the V key. Choosing the View tool changes the contents of the toolbar that appears immediately below the main menu bar. When the Views pointer is active, this toolbar contains a schemata list and a color chart list.

Use these lists to select the appropriate schema and color accent for the new view. Make sure that you associate the new view with a database. The color of your view can be changed using the Properties palette. Create a view by clicking anywhere on the EER Diagram canvas.

This creates a new view with the default name view1. Right-clicking a view opens a pop-up menu. With the exception of the delete item, these menu items function as described in Section 9. This opens the view editor docked at the bottom of the application. Double-clicking the title bar undocks the editor. Do the same to redock it.

Any number of views may be open at the same time. Each additional view appears as a tab at the top of the view editor. There are three tabs at the bottom of the view editor: View , Comments , and Privileges. The Privileges tab of the view editor functions in exactly the same way as the Privileges tab of the routine editor. When you select a view on the EER Diagram canvas, its properties are displayed in the Properties palette.

Most of the properties accessible from the Properties palette apply to the appearance of a view on the EER Diagram canvas. For a list of properties accessible through the Properties palette, see Section 9. After the schema has been added to the current model, you can see the schema objects on the Physical Schemata panel on the MySQL Model page. The Routines and Routine Groups are listed there. MySQL Workbench unifies both stored procedures and stored functions into one logical object called a Routine.

Routine Groups are used to group related routines. Define Routine with the Routine Group Editor to assign specific routines to a group, using a drag and drop interface. Placing individual routines on the diagram is not permitted, as it would clutter the canvas. The default name of the routine is routine1. If a routine with this name already exists, the new routine is named routine2. Adding a new routine automatically opens the routine editor docked at the bottom of the application.

For information about using the routine editor, see Section 9. The Edit Routine The cut and paste items are useful for copying routines between different schemata. Deleting the code for a routine from the Routines tab of the Routine Group Editor results in removal of the routine object from the model.

To remove a routine from a routine group, use the controls on the Routine Group tab of the Routine Group Editor. This opens the routine editor docked at the bottom of the application. Any number of routines may be open at the same time.

Each additional routine appears as a tab at the top of the routine editor. Routine and Privileges tabs appear at the bottom of the routine editor. Use the Routine tab of the routine editor to perform the following tasks:. Rename the routine using the Name field. The Privileges tab of the routine editor allows you to assign specific roles and privileges.

You may also assign privileges to a role using the role editor. For a discussion of this topic, see Section 9. When this tab is first opened, all roles that have been created are displayed in the list on the right. Move the roles you wish to associate with this table to the Roles list on the left. Use the Shift key to select multiple contiguous roles and the Control key to select noncontiguous roles. To assign privileges to a role, click the role in the Roles list.

This displays all available privileges in the Assigned Privileges list. The privileges that display are:. You can choose to assign all privileges to a specific role or any other privilege as listed previously. Privileges irrelevant to a specific table, such as the FILE privilege, are not shown. If a role has already been granted privileges on a specific table, those privileges show as already checked in the Assigned Privileges list. If a routine group with this name already exists, the new routine group is named routines2.

Adding a new routine group automatically opens the routine groups editor docked at the bottom of the application. For information about using the routine groups editor, see Section 9. The Edit Routine Group The cut and paste items are useful for copying routine groups between different schemata. Deleting a routine group from the MySQL Model page removes the group but does not remove any routines contained in that group.

Any routine groups added to the Physical Schemata also show up in the Catalog palette on the right side of the application. They may be added to an EER diagram by dragging and dropping them from this palette. Make sure that the EER Diagram tab is selected, then right-click the routine groups icon on the vertical toolbar. The routine groups icon is immediately above the lowest toolbar separator. Clicking the mouse on this icon changes the mouse pointer to a routine group pointer. You can also change the mouse pointer to a routine pointer by pressing the G key.

Choosing the Routine Group tool changes the contents of the toolbar that appears immediately below the menu bar. When the Routine Groups pointer is active, this toolbar contains a schemata list and a color chart list. Use these lists to select the appropriate schema and color accent for the new routine group. Make sure that you associate the new routine group with a database. The color of your routine group can be changed later using the Properties palette.

Create a routine group by clicking anywhere on the EER Diagram canvas. This creates a new routine group with the default name routines1. Right-clicking a routine group opens a pop-up menu. With the exception of the delete option and rename options, these menu options function as described in Section 9. There is no rename option, and the behavior of the delete option is determined by your MySQL Workbench options settings.

This opens the routine group editor docked at the bottom of the application. Any number of routine groups may be open at the same time. Each additional routine group appears as a tab at the top of the routine editor,. Routine group and Privileges tabs appear at the bottom of the routine editor. Use the Routine Groups tab of the routine groups editor to perform the following tasks:. Rename the routine group using the Name field. The Privileges tab of the routine group editor functions in exactly the same way as the Privileges tab of the table editor.

When you select a routine group on the EER Diagram canvas, its properties are displayed in the Properties palette. All of the properties accessible from the Properties palette apply to the appearance of a routine group on the EER Diagram canvas. You can add layers to a database only from an EER Diagram.

Layers are used to help organize objects on the canvas. Typically, related objects are added to the same layer; for example, you may choose to add all your views to one layer. Select an EER Diagram tab and left-click the layer icon on the vertical toolbar.

Clicking the mouse on this icon changes the mouse pointer to a layer pointer. You can also change the mouse pointer to a layer pointer by pressing the L key. Choosing the Layer tool changes the contents of the toolbar that appears immediately below the menu bar. When the Layers pointer is active, this toolbar contains a color chart list. Use this list to select the color accent for the new layer.

The color of your layer can be changed later using the Properties palette. Create a layer by clicking anywhere on the EER Diagram canvas and, while holding the left mouse button down, draw a rectangle of a suitable size. This creates a new layer with the default name layer1. To open the layer editor, either double-click the layer or right-click the layer and choose the edit option. The available context-menu options are:.

A layer may also be edited via Properties Editor on the left panel, and it offers additional edit options. Since layers are not schema objects, no confirmation dialog box opens when you delete a layer regardless of how you have configured MySQL Workbench. Deleting a layer does not delete schema objects from the catalog. To add an object to a layer, drag and drop it directly from the Catalog palette onto a layer. Locking objects to a layer prevents their accidental removal.

You cannot remove them by clicking and dragging; to remove an object, you also must press the Control key while dragging it. If you drag a layer over a table object, the table object will automatically be added to the layer. This also works for multiple table objects.

Choosing "Edit" allows you to edit the layer name and layer background color, and the "Properties Editor" offers additional edit options. When you select a layer on the EER Diagram canvas, its properties are displayed in the Properties palette. The properties accessible from the Properties palette apply to the appearance of a layer on the EER Diagram canvas. In some circumstances, you may want to make a layer invisible. Select the layer and, in the Properties palette, set the visible property to False.

To locate an invisible object, open the Layers palette and select the object by double-clicking it. After an object is selected, you can reset the visible property from the Properties palette. In addition to the properties listed there, a layer also has a description property. Use this property to document the purpose of the layer. Notes are typically used to help document the design process. If a note with this name already exists, the new note is named note2.

Adding a new note automatically opens the note editor docked at the bottom of the application. For information about using the note editor, see Section 9. The Edit Note This opens the note editor docked at the bottom of the application. Double-clicking the note tab undocks the editor. Double-click the title bar to redock it. Any number of notes may be open at the same time. Each additional note appears as a tab at the top of the note editor.

Text objects are applicable only to an EER diagram. They can be used for documentation purposes; for example, to explain a grouping of schema objects. Make sure that the EER Diagram tab is selected, then right-click the text object icon on the vertical toolbar. The text object icon is the rectangular icon found below the label icon.

Clicking the mouse on this icon changes the mouse pointer to a text object pointer. You can also change the mouse pointer to a text object pointer by pressing the N key. Choosing the Text Object tool changes the contents of the toolbar that appears immediately below the menu bar.

When the Text Object pointer is active, this toolbar contains a color chart list. Use this list to select the color accent for the new text object. The color of your text object can be changed later using the Properties palette. Create a text object by clicking anywhere on the EER Diagram canvas.

This creates a new text object with the default name text1. Right-clicking a text object opens a pop-up menu. These menu options are identical to the options for other objects. However, since a text object is not a database object, there is no confirmation dialog box when you delete a text object. To invoke the text object editor, double-click a text object on the EER Diagram canvas. This opens the editor docked at the bottom of the application.

Double-clicking the text object table undocks the editor. Any number of text objects may be open at the same time. Each additional text objects appears as a tab at the top of the text editor. When you select a text object on the EER Diagram canvas, its properties are displayed in the Properties palette. There is no property in the Properties palette for changing the font used by a text object. To do so, choose the Appearance tab of the Workbench Preferences dialog. For more information, see Preferences: Modeling: Appearance.

Make sure that the EER Diagram tab is selected, then right-click the image icon on the vertical toolbar. The image icon is the icon just above the table icon. Clicking the mouse on this icon changes the mouse pointer to an image pointer. You can also change the mouse pointer to an image pointer by pressing the I key.

Create an image by clicking anywhere on the EER Diagram canvas. This opens a file open dialog box. Select the desired image, then close the dialog box to create an image on the canvas. Cut 'Image'. Copy 'Image'. Delete 'Image'. These menu items function in exactly the same way as they do for other objects on an EER diagram. However, images are not database objects so there is no confirmation dialog box when they are deleted. To invoke the image editor, double-click an image object on an EER Diagram canvas.

This opens the image editor docked at the bottom of the application. Double-clicking the image editor tab undocks the editor. Any number of images may be open at the same time. Each additional image appears as a tab at the top of the image editor. Use the Image tab of the image editor to perform the following tasks:. Browse for an image using the Browse button. To create documentation of your models, see Section 9. The printing menu items not enabled unless an EER Diagram is active.

These items are available:. Sends your EER Diagram directly to the printer. This option generates a preview before printing. From the preview you can adjust the scale of the view and also choose a multi-page view. Clicking the printer icon at the top left of this window, prints the currently selected EER Diagram.

Close the print preview window if you need to adjust the placement of objects on the EER Diagram canvas. When you click a template, a preview image displays on the right side of the page. From the Base Options frame choose the report title and the output directory for the report files. Available on Linux and OS X versions only. The following table shows typical values for common platforms:. January is 01 and December is For example, the 12th would be List Foreign Keys that refer to that table : Display the tables that foreign keys reference.

Clicking the Generate button creates the directory defined in the Output directory text box. This is used if the vibrant style is chosen. Choosing the Text Basic option creates a directory containing one text file. You can click index.

If you wish to create custom templates please refer to Section 9. MySQL Workbench provides validation modules so that you can test your models before implementing them. The validation plugins are accessed from the Model menu. Beneath these menu items are a number of specific validation tests.

Running any one of these tests opens an output window docked at the bottom of the application. Warning messages are displayed on the left side of this window and the tests performed are displayed on the right. The following list names the general validation types and gives examples of specific violations:.

Objects such as tables that do not appear on at least one EER Diagram. Duplicated Identifiers Validation. A foreign key that refers to a column other than the primary key in the source table. Any object that is object is either read only or write only by role definition. The following list names the MySQL-specific validation types and gives examples of specific violations:.

A foreign key defined for an engine type that does not support foreign keys not yet implemented. A view or routine that references a nonexistent table not yet implemented. This chapter contains three short tutorials intended to familiarize you with the basics of MySQL Workbench. Creating a database from scratch is the focus of Section 9. Examples taken from the sakila database are used throughout the documentation, so this installation procedure is recommended.

This section provides a tutorial introduction to MySQL models by showing you how to create a new database model, and how to forward engineer a model to a live MySQL server. Alternatively, you can create a model from a database by using the reverse engineering wizard. A model can contain multiple schemata. Note that when you create a new model, it contains the mydb schema by default. You can change the name of this schema to serve your own purposes, or delete it.

Confirm this change in the Physical Schemata panel. Now you are ready to add a table. Double-click Add Table in the Physical Schemata section. This automatically loads the table editor with the default table name table1. Next, add columns to your table. Note that the EER Diagram is automatically updated to reflect this change.

To open the table editor, either change back to the MySQL Model tab and right-click on the movies table, or right-click on movies in the EER diagram and select an Edit 'movies' option. Enter a model name at the file prompt. This tutorial assumes you followed the previous Section 5. Now forward engineer your model to the live MySQL server.

Select Database , Forward Engineer We do not require connection changes so click Next. The Options page lists optional advanced options. For this tutorial, you can ignore these and click Next. Select an object to export to the live MySQL server.

Review the script to make sure that you understand the operations that will be carried out. Click Next to execute the Forward Engineering process. The Commit Progress page confirms that each step was executed. Click Show Logs to view the logs. If no errors are present, click Close to close the wizard.

Ensure that your model is saved. Click Save Model to Current File on the main toolbar. This creates and opens a new EER Diagram canvas. Start by creating a table using the table tool. The table tool is the rectangular grid in the middle of the vertical toolbar.

Mousing over it shows the message, Place a New Table T. Clicking this tool changes the mouse pointer to a hand with a rectangular grid. Create a table on the canvas by clicking anywhere on the EER Diagram grid. Right-click the table and choose Edit in New Window from the pop-up menu. This opens the table editor, docked at the bottom of the application. The table name defaults to table1. Change the name by entering invoice into the Name: field.

Changes here affect the name of the tab in the table editor and the name of the table on the canvas. Pressing Tab or Enter while the cursor is in the table name field selects the Columns tab of the table editor and creates a default column named idinvoice.

Notice that a field has been added to the table on the EER canvas. Pressing Tab yet again and the focus shifts to adding a second column. When you are finished, close the table editor, by clicking the x button on the top left of the table editor. Select the table tool again and place another table on the canvas.

Next click the 1:n Non-Identifying Relationship tool. Next, click the invoice table. This relationship between the two tables is shown graphically in crow's foot notation. Revert to the default mouse pointer by clicking the arrow at the top of the vertical toolbar. Click the Foreign key Name field.

The referenced table should show in the Referenced Table column and the appropriate column in the Referenced Column column. Experiment with the other tools on the vertical toolbar. Delete a relationship by selecting the eraser tool and clicking the line joining two tables. Create a view, add a text object, or add a layer. After downloading the file, extract it to a convenient location.

Find and import the sakila-schema. This is the script that contains the data definition statements for the sakila database. To view the newly imported script, expand the Physical Schemata section by double-clicking the arrow on the left of the Physical Schemata title bar. Select the tab labeled sakila. You may also wish to remove the default schema tab, mydb. Select this tab, then click the - button on the upper right in the Physical Schemata panel.

To view all the objects in the sakila schema, you may need to expand the Physical Schemata window. Move the mouse pointer anywhere over the gray area that defines the lower edge of the Physical Schemata window. Hold down the right mouse button and move the mouse to adjust the size of the window. After you have expanded the window, all the objects in the sakila database should be visible. Tables appear at the top followed by views and then routines.

There are no routine groups in this schema, but you should see the Routine Groups section and an Add Group icon. The EER Diagram canvas is where object modeling takes place. To add a table to the canvas, select the Catalog tab in the middle panel on the right side of the application to display any schemata that appear in the MySQL Model tab.

Expand the tables list in the same way. You can add tables to the EER canvas by dragging them from the Catalog panel dropping them onto the canvas. Drop the address table and the city table onto the canvas. MySQL Workbench automatically discovers that address. Drop the country table onto the canvas and immediately you should see the relationship between the country table and the city table.

To view all the relationships in the sakila database, see Figure 9. Click the Properties tab of the panel on the lower left, then click one of the tables on the canvas. This displays the properties of the table in the Properties window. While a table is selected, you can use the Properties window to change a table's properties.

For example, entering FF for the color value will change the color accent to red. Changing the color of a table is a good way to identify a table quickly—something that becomes more important as the number of tables increases. Changing the color of a table is also an easy way to identify a table in the Model Navigator panel.

This panel, the uppermost panel on the left side of the page, gives a bird's eye view of the entire EER canvas. You can begin designing a database by using this default schema. To change the name of the default schema, double-click the schema tab. This opens a schema editor window docked at the bottom of the application. To undock or redock this window, double-click anywhere in the editor title bar.

To rename the schema, use the field labeled Name. After you have renamed the schema, a lightning bolt icon appears right aligned in the Name field, indicating that other changes are pending. Click the Comments field and a dialog box opens asking if you wish to rename all schema occurrences.

Clicking Yes ensures that your changes are propagated throughout the application. Add comments to the database and change the collation if you wish. Close the schema editor by clicking the x button. Create a new table by double-clicking the Add Table icon in the Physical Schemata panel. This opens the table editor docked at the bottom of the application. If you wish, you can undock or dock this editor in exactly the same way as the schema editor window.

Initially, the table name defaults to 'table1' in the table editor. The following screenshot describes the available actions:. In our example above, columns were added using the Columns tab. Clicking an empty row will add a new column, and clicking an existing column starts edit mode. Click the Tab key to move to the next column and set the column's data type. Altering the table by adding indexes or other features is also possible using the table editor by clicking each tab within the table editor.

Additional objects such as views or routines can be added in the same way as tables. Objects are listed under the Catalog palette on the right. To view these schema objects, select the Catalog tab in the middle palette on the right. This chapter highlights the capabilities of MySQL Workbench as a documentation tool using the sakila database as an example. An EER diagram provides a quick overview and understanding of a database. Rather than reading through table definition statements, a quick glance at an EER diagram indicates how tables are related.

You can also see how tables are related; what the foreign keys are and what the nature of the relationship is. Find following an EER diagram showing all the tables in the sakila database. The object notation style used in Figure 9. This notation shows only primary keys and no other columns, which is especially useful where space is at a premium.

The relationship notation is the default, Crow's Foot. Some tables have two foreign keys that relate to the same table. Where more than one relationship exists between two tables, the connection lines run concurrently. Identifying and nonidentifying relationships are indicated by solid and broken lines respectively.

MySQL Workbench provides capabilities to forward engineering physical database designs. A visual data model can be transformed into a physical database on a target MySQL Server by executing the forward engineering wizard. All SQL code is automatically generated to help eliminate the normal error-prone process of manually writing complex SQL code.

MySQL Workbench also enables you to reverse engineer an existing database or packaged application to get better insight into its database design. In addition to forward and reverse engineering existing databases, it can also import SQL scripts to build models, and export models to DDL scripts to execute at a later time. It is possible to forward engineer a database using an SQL script or by connecting to a live database. To create a script of your database model, choose the Export item from the File menu.

You may export a script to alter an existing database or create a new database. The following figure shows the first page of the wizard. Leave this field blank to view, but not save, the generated output. Select this option to generate a statement to drop each object before the statement that creates it. This ensures that any existing instance of each object is removed when the output is executed. Select this option to generate unqualified object names in SQL statements.

This causes display of any warnings generated when the output is executed, which can be useful for debugging. Do Not Create Users. Only Export Privileges. Select this option to update the privileges of existing users, as opposed to creating new users. Exporting users that already exist will also result in an error. Select this option if you have added any rows to a table. For more information about inserting rows, see Section 8. Use Show Filter to fine tune filter the objects for export.

After selecting the objects to export, click Hide Filter to hide the filter panel. After selecting the objects to export, click Next to review the generated script. Alternatively, you can click File and then New Model from the menu shown in the figure that follows.

A model can contain multiple schemas. Note that when you create a new model, it contains the mydb schema by default. You can change the name of this default schema as needed or you can delete it. Confirm this change in the Physical Schemas panel shown in the next figure. Now you are ready to add a table. Double-click Add Table in the Physical Schemas section. This automatically loads the table editor with the default table name table1.

Edit the Table Name field to change the table name from table1 to movies. Next, add columns to your table. Double-click a Column Name cell and the first field defaults to moviesid because by default MySQL Workbench appends id to the table name for the initial field. Add the two additional columns described in the following table. The figure that appears after the table shows all three columns in the movies table.

The next figure shows the a new tab titled EER Diagram , which displays diagram representation of the movies table and columns. Note that the EER Diagram is automatically updated to reflect this change. To open the table editor, either change back to the MySQL Model tab and right-click on the movies table, or right-click on movies in the EER diagram and select an Edit 'movies' option. This tutorial assumes you have created a connection already. If not, see Section 5. Make any necessary connection changes and then click Next.

The Options step lists optional advanced options as shown in the figure that follows. For this tutorial, you can ignore these options and click Next. Select an object to export to the live MySQL server. Review the script to make sure that you understand the operations that will be carried out. Click Next to execute the forward-engineering process. The Commit Progress step confirms that each task was executed.

Click Show Logs to view the logs. If no errors are present, click Close to close the wizard. Click the Save Model to Current File icon on the menu toolbar to save the model. For additional information about data modeling, see Chapter 9, Database Design and Modeling.
