MySQL BETWEEN Clause

You can use BETWEEN clause to replace a combination of "greather than equal AND less than equal" conditions.

To understand BETWEEN clause 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 records with conditions daily_typing_pages more than 170 and equal and less than 300 and equal. This can be done using >= and <= conditions as follows

mysql>SELECT * FROM employee_tbl 
    ->WHERE daily_typing_pages >= 170 AND
    ->daily_typing_pages <= 300;
+------+------+------------+--------------------+
| 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 |
|    4 | Jill | 2007-04-06 |                220 |
|    5 | Zara | 2007-06-06 |                300 |
+------+------+------------+--------------------+
5 rows in set (0.03 sec)

Same can be achieved using BETWEEN clause as follows:

mysql> SELECT * FROM employee_tbl 
    -> WHERE daily_typing_pages BETWEEN 170 AND 300; 
+------+------+------------+--------------------+
| 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 |
|    4 | Jill | 2007-04-06 |                220 |
|    5 | Zara | 2007-06-06 |                300 |
+------+------+------------+--------------------+
5 rows in set (0.03 sec)
