how to debug stored procedure in mysql workbench

Debugging MySQL Functions · Only when you want a counter, create one session level variables. · Create an in-memory table to store debugging. Expand the Stored Procedures folder. Only stored procedures can be debugged directly. To debug a user-defined function, create a stored procedure that calls the function. To compile the stored procedure for debugging, navigate to the required procedure in Database Explorer, select Compile, and then click Compile Dependants for.

To debug a user-defined function, create a stored procedure that calls the function. Click on a stored procedure node, then right-click and from the context menu choose Debug Routine. At this point, Visual Studio switches to debug mode, opening the source code of the routine being debugged in step mode, positioned on the first statement.

If the initial routine you debug has one or more arguments, a pop-up will show up with a grid a row per each argument and three columns: one for the argument, one for the argument value this is editable and one for nullifying that argument value a check box. After setting up all the argument values, you can press OK to start the debug session, or Cancel to cancel the debug session. To have visibility into the internal workings of a stored routine, the debugger prepares a special version of the procedure, function, or trigger being debugged, instrumented with extra code to keep track of the current line being stepped into and the values of all the local variables.

Any other stored procedures, functions, or triggers called from the routine being debugged are instrumented the same way. GetFolderPath Environment. ApplicationData in. Two threads are used, one for the debugger and one for the routine being debugged. The threads run in strict alternation, switching between the debugger and the routine as each statement is executed in the stored routine.

In particular, the following are true:. To show the Locals tab, choose the menu item Debug , Windows , Locals. The Locals tab lists all the variables available in the current scope: variables defined with DECLARE at any point in the routine, argument parameters, and session variables that are referenced.

If the last step operation changes the value of a local, its value will be highlighted in red until another statement is executed or stepped. To show the Watch tab, choose the menu item Debug , Windows , Watch. To define a watch, type any valid MySQL expression, optionally including function calls. If the watch evaluation makes sense in the current context current stack frame , it will show its value, otherwise it will show an error message in the same row the watch was defined.

When debugging a trigger, in addition to any locals declared or session variables referenced, the new and old object when applicable will be listed. These variables from the new and old objects can be manipulated the same way as any ordinary local variable. The stack trace in the Call Stack tab will list all the stack traces, one for each routine invocation.

The one with a yellow mark is the current stepping point. Clicking in another will activate in the editor the tab for that routine source, highlighting in green the last statement stepped. Stepping of a new routine starts in the first executable instruction excluding declares, handlers, cursor declarations, and so on. To step into the code of a condition handler, the condition must be triggered in the rest of the MySQL routine. You can step out of any of functions, triggers or stored procedures.

If you step from the main routine, it will run that routine to completion and finish the debug session. You can step over stored procedure calls, stored functions, and triggers. To step over a trigger, step over the statement that would cause the trigger to fire. When stepping into a single statement, the debugger will step into each individual function invoked by that statement and each trigger fired by that statement.

The order in which they are debugged is the same order in which the MySQL server executes them. Also, the number of times you enter into a stored function or trigger depends on how many rows are evaluated by the function or affected by the trigger. For example, if you press F11 Step Into into an UPDATE statement that modifies three rows calling a function for a column in the SET clause, thus invoking the function for each of the three rows , you will step into that function three times in succession, once for each of the rows.

In this example, the order in which the different instances of the stored function are debugged is server-specific: the same order used by the current MySQL server instance to evaluate the three function invocations. To show the Breakpoints tab, choose the menu item Debug , Windows , Breakpoints. The Breakpoints tab will show all the breakpoints defined. From here, you can enable and disable breakpoints one by one or all at once using the toolbar on top of the Breakpoints tab.

You can define new breakpoints only in the middle of a debug session. In the familiar Visual Studio way, you press F9 once to create a breakpoint in that line, and press it again to remove that breakpoint. Once a breakpoint is defined, it will appear enabled as filled red circle left to the current row if that line is a valid statement to put a breakpoint or disabled as a non-filled red circle left to the current row if that row is not valid to put a breakpoint.

To define conditional breakpoints, after creating the breakpoint, right click in the red dot and choose Condition The former will trigger the breakpoint every time the condition is true, the latter every time the condition value has changed. If you define a conditional breakpoint, it is not enough to step into the line with the breakpoint defined to trigger such a breakpoint. To define pass count breakpoints, after creating the breakpoint, right click in the red dot and choose Hit Count In the pop-up dialog, define the specific condition to set.

For those who are close to us and need a little extra help from time to time, here are the instructions:. For debugging, you must establish your own connection to the database that currently contains the stored procedure. In Server Explorer, under Connect to Database, also enter the desired relationship. After you are our And the database you want, you can now start using Server Explorer to browse through the different parts of the database.

Open the same Data Connections section that is probably now available in Server Explorer and expand the database you want to connect to. Open that file and find the only stored procedure you really want to debug. A new query window will open where you can follow the neat procedure as shown below. In the upper corner next to the green pointer, you will see the familiar drop-down menu do not click the green arrow.

Click each arrow in the drop-down list and select Run With Debugger. This will start by executing a specific stored procedure and allow you to use familiar debugging alternatives such as Step In, Step Over, Continue, etc. A good programmer should know his toolbox well and make the best use of it according to his ability. What tools are valuable to your job? In order for you to debug a. Solution Explorer displays right mouse button indicator not solution andOpen property pages.

Click Configure. The properties currently display a tree structure. In Server Explorer, find and open the current stored procedure. Right-click the stored procedure and select Edit Saved. Sometimes, when writing stored procedures, you need some debugging tools. With which we can basically add breakpoints to easily debug SQL queries and keep track of variables.

You removed some options because we can easily communicate with SQL Server from Visual Studio and debug stored procedures after connecting to the server. Go to the Visual Studio Search and Installer launch menu and click it. After opening the Visual Studio installer under Workloads, test the storage and handling of data. This will enter debug mode. This is all you need to enable debugging in Visual Studio and get it done.

Debugging the complex code that makes up a program can help you better understand some of the logic being used in a relatively shorter amount of time.
