MySQL Modulus

MySQL Modulus refer to the remainder value obtained when a value 'a' is divided by 'b'.

Understand with Example

The Tutorial illustrate an example from 'MySQL Modulus'. To understand and elaborate the example we create a table 'oddeven' that has the required fieldnames and datatypes respectively.

Query for creating table named oddeven:

mysql> create table oddeven
    -> (
    -> a int(30),
    -> b int(35));
Query OK, 0 rows affected (0.08 sec)

Query for inserting data into table named oddeven:

The insert into is used to add the records or rows in the table oddeven.

mysql> insert into oddeven
    ->   values
    ->   (11,23),(23,23),(24,23),(25,25),(62,27),(72,29);
Query OK, 6 rows affected (0.02 sec)
Records: 6  Duplicates: 0  Warnings: 0

Query for viewing data of table named oddeven:

mysql> select * from oddeven;
+------+------+
| a    | b    |
+------+------+
|   11 |   23 |
|   23 |   23 |
|   24 |   23 |
|   25 |   25 |
|   62 |   27 |
|   72 |   29 |
+------+------+
6 rows in set (0.00 sec)

Query for finding mod of the two fields from table named oddeven:

The Query b MOD a is used to return the remainder value  as a result from table 'oddeven'. The below example returns remainder values as column name b mod a  when the values in column  b is divided by values in column a.

mysql> SELECT b MOD a from oddeven;
+---------+
| b MOD a |
+---------+
|       1 |
|       0 |
|      23 |
|       0 |
|      27 |
|      29 |
+---------+
6 rows in set (0.00 sec)
