Division Operator (/)

The division operator (/) in SQL Server is used to perform arithmetic division on numeric values. It divides one number by another and returns the result as a numeric value.

Syntax:

SELECT number1 / number2 AS result;

Example:

SELECT 10 / 2 AS Result;

Output:

5

In this example, the division operator calculates the quotient of dividing 10 by 2, resulting in 5.
