The example below shows the usage of GET_FORMAT() function.

SELECT GET_FORMAT(DATETIME, 'INTERNAL');

Result: '%H:%i:%s'

SELECT DATE_FORMAT('2018-08-18', GET_FORMAT(DATE,'USA'));
Result: '08.18.2018'

SELECT STR_TO_DATE('08.18.2018', GET_FORMAT(DATE,'USA'));
Result: '2018-08-18'

Example 2:

Consider a database table called Employee with the following records:

EmpID	Name	City	Age	Date_of_Joining
1	John	London	25	2018-05-25
2	Marry	New York	24	2018-10-15
3	Jo	Paris	27	2019-06-09
4	Kim	Amsterdam	30	2019-09-21
5	Ramesh	New Delhi	28	2019-10-25

In the query below, the DATE_FORMAT() function is used to format the date value of Date_of_Joining column:

SELECT *, 
DATE_FORMAT(Date_of_Joining, GET_FORMAT(DATE, 'USA')) AS DATE_FORMAT_Value
FROM Employee;

This will produce a result similar to:

EmpID	Name	City	Age	Date_of_Joining	DATE_FORMAT_Value
1	John	London	25	2018-05-25	05.25.2018
2	Marry	New York	24	2018-10-15	10.15.2018
3	Jo	Paris	27	2019-06-09	06.09.2019
4	Kim	Amsterdam	30	2019-09-21	09.21.2019
5	Ramesh	New Delhi	28	2019-10-25	10.25.2019
