# MySQL MIN Function

MySQL MIN function is used to find out the record with minimum value among a record set.

To understand MIN function consider an employee_tbl table which is having following records:

    mysql> SELECT * FROM employee_tbl;
    +------+------+------------+--------------------+
    | id   | name | work_date  | daily_typing_pages |
    +------+------+------------+--------------------+
    |    1 | John | 2007-01-24 |                250 |
    |    2 | Ram  | 2007-05-27 |                220 |
    |    3 | Jack | 2007-05-06 |                170 |
    |    3 | Jack | 2007-04-06 |                100 |
    |    4 | Jill | 2007-04-06 |                220 |
    |    5 | Zara | 2007-06-06 |                300 |
    |    5 | Zara | 2007-02-06 |                350 |
    +------+------+------------+--------------------+
    7 rows in set (0.00 sec)

Now suppose based on the above table you want to fetch minimum value of daily_typing_pages, then you can do so simply using the following command:

    mysql> SELECT MIN(daily_typing_pages)
        -> FROM employee_tbl;
    +-------------------------+
    | MIN(daily_typing_pages) |
    +-------------------------+
    |                     100 |
    +-------------------------+
    1 row in set (0.00 sec)

You can find all the records with minimum value for each name using GROUP BY clause as follows:

    mysql> id, name, work_date, MIN(daily_typing_pages)
        -> FROM employee_tbl GROUP BY name;
    +------+------+------------+-------------------------+
    | id   | name | work_date  | MIN(daily_typing_pages) |
    +------+------+------------+-------------------------+
    |    3 | Jack | 2007-05-06 |                     100 |
    |    4 | Jill | 2007-04-06 |                     220 |
    |    1 | John | 2007-01-24 |                     250 |
    |    2 | Ram  | 2007-05-27 |                     220 |
    |    5 | Zara | 2007-06-06 |                     300 |
    +------+------+------------+-------------------------+
    5 rows in set (0.00 sec)

You can use MIN Function alongwith MAX function to find out minimum value as well. Try out following example:

    mysql> SELECT MIN(daily_typing_pages) least, MAX(daily_typing_pages) max
        -> FROM employee_tbl;
    +-------+------+
    | least | max  |
    +-------+------+
    |   100 |  350 |
    +-------+------+
    1 row in set (0.01 sec)
