Comparison operator between dates will work in a logical way. In the following example, while comparing two dates, MySQL is simply comparing two numbers or string −
mysql> select 20171027 < 20150825; +---------------------------+ | 20171027 < 20150825 | +---------------------------+ | 0 | +---------------------------+ 1 row in set (0.00 sec)
The 0 output shows that the result of the above query is FALSE.
mysql> select 20171027 > 20150825; +--------------------------+ | 20171027 > 20150825 | +--------------------------+ | 1 | +--------------------------+ 1 row in set (0.00 sec)
The output ‘1’ shows that the result of the above query is TRUE.
