Example 2:

Consider a database table called EmployeeLogin with the following records:

EmpID	Name	LoginStamp
1	John	2019-10-25 09:20:38
2	Marry	2019-10-25 09:21:05
3	Jo	2019-10-25 09:24:35
4	Kim	2019-10-25 09:25:24
5	Ramesh	2019-10-25 09:27:16
6	Suresh	2019-10-25 09:28:19

To extract the HOUR_MINUTE part from the records of LoginStamp column, the following query can be used:

SELECT *, EXTRACT(HOUR_MINUTE FROM LoginStamp) AS EXTRACT_Value FROM EmployeeLogin;

This will produce a result similar to:

EmpID	Name	LoginStamp	EXTRACT_Value
1	John	2019-10-25 09:20:38	920
2	Marry	2019-10-25 09:21:05	921
3	Jo	2019-10-25 09:24:35	924
4	Kim	2019-10-25 09:25:24	925
5	Ramesh	2019-10-25 09:27:16	927
6	Suresh	2019-10-25 09:28:19	928
