MariaDB HOUR() Function



The MariaDB HOUR() function returns the hour portion of a given time or datetime value. Since a time value can range from '-838:59:59' to '838:59:59', therefore this function can return value between 0 to 838 (higher than 23).

Syntax

SELECT HOUR("838:38:42");

Example 2:

Consider a database table called Orders with the following records:

OrderQuantityPriceOrderTime
1001.582017-08-18 10:38:42
1201.612018-03-23 07:14:16
1251.782018-09-12 05:25:56
501.802019-01-16 11:52:05
2001.722020-02-06 09:31:34

The query given below can be used to get the hour portion of records of column OrderTime:

SELECT *, HOUR(OrderTime) AS HOUR_Value FROM Orders;

This will produce the result as shown below:

OrderQuantityPriceOrderTimeHOUR_Value
1001.582017-08-18 10:38:4210
1201.612018-03-23 07:14:167
