Get the minimum and maximum value from a VARCHAR column and display the result in separate MySQL columns?

Let us first create a table −

mysql> create table DemoTable (    Value varchar(100) ); Query OK, 0 rows affected (0.75 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('190'); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable values('230'); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable values('120'); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable values('189'); Query OK, 1 row affected (0.19 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+-------+ | Value | +-------+ | 190 | | 230 | | 120 | | 189 | +-------+ 4 rows in set (0.00 sec)

Following is the query to get the minimum and maximum value from a VARCHAR column and display the result in separate MySQL columns −

mysql> select min(cast(Value AS SIGNED)) AS Min, max(cast(Value AS SIGNED)) AS Max from DemoTable;

This will produce the following output −

+------+------+ | Min | Max | +------+------+ | 120 | 230 | +------+------+ 1 row in set (0.03 sec)
