Here, now() represents the current date. To check whether it falls between two specific dates, you need to use the BETWEEN. Let us first create a table −mysql> create table DemoTable    (    FirstDate datetime,    SecondDate datetime    ); Query OK, 0 rows affected (0.60 sec)Insert some records in the table using insert command −mysql> insert into DemoTable values('2019-04-01', '2019-05-02'); Query OK, 1 row affected (0.23 sec) mysql> insert into DemoTable values('2019-05-28', '2019-06-04'); Query OK, 1 row affected (0.27 sec) mysql> insert into DemoTable values('2016-01-31', '2019-03-01'); Query OK, 1 row affected (0.15 sec)Display all records from the table ...

Use GREATEST() to find the maximum.

Use ORDER BY clause for this. Let us first create a table −mysql> create table DemoTable    (    Value1 int,    Value2 int    ); Query OK, 0 rows affected (0.54 sec)Insert some records in the table using insert command −mysql> insert into DemoTable values(10, 40); Query OK, 1 row affected (0.20 sec) mysql> insert into DemoTable values(50, 5); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable values(51, 56); Query OK, 1 row affected (0.18 sec) mysql> insert into DemoTable values(52, 78); Query OK, 1 row affected (0.16 sec) mysql> insert into DemoTable values(90, 7); Query ...
