HOUR

Syntax

HOUR(time)

Description

Returns the hour for time. The range of the return value is 0 to 23 for time-of-day values. However, the range of TIME values actually is much larger, so HOUR can return values greater than 23.

The return value is always positive, even if a negative TIME value is provided.

Examples

SELECT HOUR('10:05:03');
+------------------+
| HOUR('10:05:03') |
+------------------+
|               10 |
+------------------+

SELECT HOUR('272:59:59');
+-------------------+
| HOUR('272:59:59') |
+-------------------+
|               272 |
+-------------------+

Difference between EXTRACT (HOUR FROM ...) (>= MariaDB 10.0.7 and MariaDB 5.5.35) and HOUR:

SELECT EXTRACT(HOUR FROM '26:30:00'), HOUR('26:30:00');
+-------------------------------+------------------+
| EXTRACT(HOUR FROM '26:30:00') | HOUR('26:30:00') |
+-------------------------------+------------------+
|                             2 |               26 |
+-------------------------------+------------------+
