Introduction to MySQL DATETIME data type By default, DATETIME values range from to For example, There are a few column datatypes for storing date and time values. They are listed in Table A The table also lists the valid ranges for each datatype. doge.ymyjsxyk.info › library › view › mysql-in-a › apas WORKBENCH MYSQL ES COMPATIBLE PARA ANTERIORES 15-19.

The hours part may be so large because the TIME type can be used not only to represent a time of day which must be less than 24 hours , but also elapsed time or a time interval between two events which may be much greater than 24 hours, or even negative. MySQL recognizes TIME values in several formats, some of which can include a trailing fractional seconds part in up to microseconds 6 digits precision. See Section 9. In particular, any fractional part in a value inserted into a TIME column is stored rather than discarded.

With the fractional part included, the range for TIME values is ' Be careful about assigning abbreviated values to a TIME column. That is, '' means '' , not ''. MySQL interprets abbreviated values without colons using the assumption that the two rightmost digits represent seconds that is, as elapsed time rather than as time of day. For example, you might think of '' and as meaning '' 12 minutes after 11 o'clock , but MySQL interprets them as '' 11 minutes, 12 seconds.

Similarly, '12' and 12 are interpreted as ''. The only delimiter recognized between a time part and a fractional seconds part is the decimal point. By default, values that lie outside the TIME range but are otherwise valid are clipped to the closest endpoint of the range. For example, '' and '' are converted to '' and ''. Invalid TIME values are converted to ''. Note that because '' is itself a valid TIME value, there is no way to tell, from a value of '' stored in a table, whether the original value was specified as '' or whether it was invalid.

See Section 5. Numeric Type Attributes. Out-of-Range and Overflow Handling. Date and Time Data Type Syntax. Unlike the numeric data types, you do not have to set a length next to the TEXT data type in the table column. The table displays the allowable storage in bytes for the TEXT data types and cases when they can be used.

In MySQL, the BLOB data type represents a binary large object and can be used to store binary media data, such as audio or video links, images, or files. For example, the maximum size of data to be stored is as follows:. This should be taken into account when comparing and sorting information. For both data types, you need to set a size parameter in characters in brackets when creating a column. For example, CHAR 3 refers to up to 3 characters for the column value. ENUM allows you to set a list of predefined values and then choose any of them.

If you add an invalid value that is not included in the list, you will get an empty string. In the table, we will insert the size column with the ENUM type. It means that this column will take only specified values. As you can see, the output displays an empty string for the invalid value of the ENUM data type column. The MySQL SET data types allow you to store zero or multiple values separated by comma you specified in a list of predefined values when creating a table.

For example, suppose that customers can wear some dresses both in autumn and winter. In the output, we may see the following options:. Integer data types are numeric values without fractions. MySQL supports the following integer data types:. The boolean data types can only accept either true or false values. In a binary format, true refers to 1 and false — to 0. As a rule, they are used for logical operations. MySQL does not have a boolean or bool data type.

When you create a table with a boolean data type, MySQL outputs data as 0, if false, and 1, if true. The Float data types represent single-precision approximate numeric values that require 4 bytes for storage. The Double data types refer to the floating-point numeric data types and use 8 bytes to store double-precision values. To sum up, decimals are better to use for fixed amounts, such as monetary and financial information price, salary, etc, , while float and double — for approximate calculations where rounding values might have a negative impact.

The BIT data type is used to store binary values in the column and accepts either 0 or 1. The range of bit values for the column goes from 1 to If the range is not set, the default value will be 1. In the days column, 1 serves as a working day and 0 — as a day-off.

Suppose in April, employees can have two additional day-offs. So, to retrieve data being converted to binary, we need to use the BIT function and view the result. Then, insert a new row into the table and retrieve data. Finally, we will add to the table the year when an employee was certified and declare the YEAR data type for the column.

Spatial data types store geometry and geography values in the table column. Starting with version 5. The JSON format allows for a quick search of values within the document using a key or array index, which, in turn, will improve overall performance and optimize storage. In addition, JSON helps validate documents and in case of invalid values, you will get an error. The maximum size is 1GB. Considering a list of MySQL data types discussed in the article, it can be important to change default data types so that they suit our needs best.

For our example, we are going to use the employees table. Then, execute the query by clicking Execute on the SQL toolbar. Alternatively, you can refresh the list of tables in Database Explorer and see the changed data type. In the article, we have reviewed MySQL data types with examples, such as string, numeric, date and time, spatial, and JSON, as well as explored data types each group includes.
