MariaDB: DATEDIFF Function
This MariaDB tutorial explains how to use the MariaDB DATEDIFF function with syntax and examples.
Description
The MariaDB DATEDIFF function returns the difference in days between two date values.
Syntax
The syntax for the DATEDIFF function in MariaDB is:
DATEDIFF( date1, date2 )
Parameters or Arguments
- date1 and date2
- The two dates to calculate the difference between. The calculation is
date1 - date2
.
Note
- Only the date portion of date1 and date2 is used in the DATEDIFF calculation. The time portion of date1 and date2 is ignored.
Applies To
The DATEDIFF function can be used in the following versions of MariaDB:
- MariaDB 10
Example
Let's look at some MariaDB DATEDIFF function examples and explore how to use the DATEDIFF function in MariaDB.
For example:
SELECT DATEDIFF('2014-05-19', '2014-05-10'); Result: 9 SELECT DATEDIFF('2014-05-19 12:17:14', '2014-05-10 10:10:08'); Result: 9 SELECT DATEDIFF('2014-05-19 11:41:14', '2014-03-24'); Result: 56 SELECT DATEDIFF('2014-05-15', '2014-04-08'); Result: 37 SELECT DATEDIFF('2014-05-28', '2013-12-31'); Result: 148 SELECT DATEDIFF('2013-12-31', '2014-05-28'); Result: -148
This last DATEDIFF example would display the difference between current system date and '2014-05-19' (current system date is returned by the CURDATE function).
SELECT DATEDIFF(CURDATE(), '2014-05-19');
