To extract part of a date/datetime expression, use the EXTRACT function. Return the number of days between two date expressions with the DATEDIFF function. The output returns the result: 06:14:21 DATEDIFF It needs to be expressed in numeric value along with the unit of the value.įind a list of unit types in the DATE_ADD section.įor instance, if you run: SELECT DATE_SUB(' 07:14:21', INTERVAL 1 HOUR) The value unitis the time/date you want to subtract. Replace date with the date expression you want to subtract from. The basic syntax: DATE_SUB(date, INTERVAL value unit) Subtract a time/date value to a date expression with the DATE_SUB or SUBDATE function. The output displays the result: Sunday January 2021 DATE_SUB or SUBDATE The date is the date expression you want to reformat, while the formatis a combination of the following specifiers:įor instance, if you run: SELECT DATE_FORMAT('', '%W %M %Y')
The basic syntax: DATE_FORMAT(date, format)
The output returns the result: 07:34:21 DATE_FORMAT It needs to be expressed in a numeric value along with the unit of the value.įor example, if you run: SELECT DATE_ADD(' 07:14:21', INTERVAL 20 MINUTE) The value unitis the time/date you want to add. Replace date with the date expression you want to add a time/date to. The basic syntax: DATE_ADD(date, INTERVAL value unit) Return the date from a datetime expression using the DATE command.įor instance, if you run: SELECT DATE(' 10:12:16') Īdd a time/date value to a date expression with the DATE_ADD or ADDDATE function. MySQL responds with the current date in the format: DATE Return the current date in the “YYY-MM-DD” or “YYYYMMDD” format with the CURDATE OR CURRENT_DATE command.įor example, if you run: SELECT CURDATE() Date-Related Functions CURDATE OR CURRENT_DATE Let’s take a look at the following example.įirst, create a table named people with birth date column with DATE data type.Note: For more MySQL functions and commands, check out our MySQL Cheat Sheet. However, a date value with two digits is ambiguous therefore you should avoid using it. Year values in the range 70-99 are converted to 1970 – 1999.Year values in the range 00-69 are converted to 2000-2069.In case you use two-digit year values, MySQL still accepts them with the following rules: MySQL stores the year of the date value using four digits. When strict mode is disabled, MySQL converts any invalid date e.g., to the zero date value. You also need to create stored functions to simulate the built-in date functions provided by MySQL, which is not recommended. If you want to store a date value that is out of this range, you need to use a non-temporal data type like integer e.g., three columns, and each column for the year, month, and day. MySQL uses 3 bytes to store a DATE value. Instead, you follow the standard date format and use the DATE_FORMAT function to format the date the way you want. This format is fixed and it is not possible to change it.įor example, you may prefer to use mm-dd-yyyy format but you can’t. MySQL uses yyyy-mm-dd format for storing a date value. MySQL DATE is one of the five temporal data types used for managing date values. Summary: in this tutorial, we will introduce you to the MySQL DATE data type and show you some useful date functions to handle the date data effectively.
