We can apply EXTRACT() function on the dates stored in MySQL table in the following way −
The following query is showing what dates are entered in table ‘testing’
mysql> Select * from testing; +-------------+---------------------+ | StudentName | Dateofreg | +-------------+---------------------+ | Ram | 2017-10-28 21:24:24 | | Shyam | 2017-10-28 21:24:30 | | Mohan | 2017-10-28 21:24:47 | | Gaurav | 2017-10-29 08:48:33 | +-------------+---------------------+ 4 rows in set (0.00 sec)
