In SQL, the MOD function is used to return the remainder of a division operation. It's particularly useful when you need to determine whether a number is even or odd, or to set conditions based on the result of the division. The basic syntax for the MOD function is as follows:

MOD(numerator, denominator)

Here, numerator is the number you want to divide, and denominator is the number you want to divide by. The outcome is the remainder of that division.

SELECT MOD(10, 3) AS Remainder;

This query would return 1 because when 10 is divided by 3, the remainder is 1.

SELECT MOD(15, 4) AS Remainder;

In this case, the result is 3 since 15 divided by 4 leaves a remainder of 3.

SELECT CASE WHEN MOD(column_name, 2) = 0 THEN 'Even' ELSE 'Odd' END AS NumberType FROM your_table;

This example uses the MOD function to determine if the numbers in column_name are even or odd. If the remainder is 0, the number is even, otherwise it is odd.

The MOD function can also be utilized in more complex scenarios, such as filtering results in a WHERE clause.

SELECT * FROM your_table WHERE MOD(id_column, 5) = 0;

This query selects rows from your_table where the id_column is a multiple of 5. Using MOD in this fashion can help in situations where grouping or pagination based on certain conditions is required.
