DIV: Perform integer division

DIV is used to perform integer division on numbers.

Example

5 DIV 2

mysql> SELECT 56 DIV 33;
+-----------+
| 56 DIV 33 |
+-----------+
|         1 | 
+-----------+
1 row in set (0.00 sec)

mysql> SELECT 56 DIV 3;
+----------+
| 56 DIV 3 |
+----------+
|       18 |
+----------+
1 row in set (0.00 sec)

I am going to use following sample data.

CREATE TABLE employee(

  id int PRIMARY KEY,

  firstName VARCHAR(20),

  lastName VARCHAR(20),

  salary DECIMAL(10, 2)

);

INSERT INTO employee VALUES (1, "Hari Krishna", "Gurram", 12345.67);

INSERT INTO employee VALUES (2, "Rama Devi", "Gurram", 1234578.67);

INSERT INTO employee VALUES (3, "Lakshmana", "Rao", 9876543.67);

INSERT INTO employee VALUES (4, "Rama", "Krishna", 1234587.67);

INSERT INTO employee VALUES (5, "Sowmya", "asd", 1238745.67);

INSERT INTO employee VALUES (6, "Jyotsna", "PS", 76543.67);

INSERT INTO employee VALUES (7, "Gireesh", "Amara", 87698);

INSERT INTO employee VALUES (8, "Sravani", "Nidamanuri", 987654);

INSERT INTO employee VALUES (9, "Saranya", "Amara", 1987654);

mysql> SELECT * FROM employee;
+----+--------------+------------+------------+
| id | firstName    | lastName   | salary     |
+----+--------------+------------+------------+
|  1 | Hari Krishna | Gurram     |   12345.67 |
|  2 | Rama Devi    | Gurram     | 1234578.67 |
|  3 | Lakshmana    | Rao        | 9876543.67 |

Get only integer part of employee salaries.

mysql> SELECT (salary DIV 1) as "Employee Salary" FROM employee;
+-----------------+
| Employee Salary |

|           12345 |
|         1234578 |

|         1238745 |
|           76543 |
|           87698 |
|          987654 |
