SQL Date Function DATE_FORMAT()

The DATE_FORMAT() function is a SQL function used to format a date or time value according to a specified format. It takes two arguments: the first argument is the date or time value to be formatted, and the second argument is a string that specifies the format.

The format string can contain various formatting codes that represent different components of the date or time value, such as year, month, day, hour, minute, and second. For example, the code "%Y-%m-%d" represents the year, month, and day in a format like "2022-02-28".

Here's an example of how to use the DATE_FORMAT() function in a SQL query:

SELECT DATE_FORMAT('2022-02-28', '%Y-%m-%d');

This query will return the date value "2022-02-28" formatted as "YYYY-MM-DD".

Note that the DATE_FORMAT() function is specific to the database management system you are using, and the format codes it supports may vary slightly depending on the system.
