Returns the remainder of one number divided by another.

Topic link icon Transact-SQL Syntax Conventions

Syntax

dividend % divisor

Arguments

dividend
Is the numeric expression to divide. dividend must be a valid expression of any one of the data types in the integer and monetary data type categories, or the numeric data type.

divisor
Is the numeric expression by which to divide the dividend. divisor must be any valid expression of any one of the data types in the integer and monetary data type categories, or the numeric data type.

Result Types

Determined by data types of the two arguments.

Remarks

You can use the modulo arithmetic operator in the select list of the SELECT statement with any combination of column names, numeric constants, or any valid expression of the integer and monetary data type categories or the numeric data type.

Examples

A. Simple example

The following example divides the number 38 by 5. This results in 7 as the integer portion of the result and demonstrates how modulo returns the remainder of 3.

SELECT 38 / 5 AS Integer, 38 % 5 AS Remainder ;

B. Example using columns in a table

The following example returns the product ID number, the unit price of the product, and the modulo (remainder) of dividing the price of each product, converted to an integer value, into the number of products ordered.

-- Uses AdventureWorks  
  
SELECT TOP(100)ProductID, UnitPrice, OrderQty,  
   CAST((UnitPrice) AS int) % OrderQty AS Modulo  
FROM Sales.SalesOrderDetail;  
GO

Examples: [!INCLUDEssSDWfull] and [!INCLUDEssPDW]

C: Simple example

The following example shows results for the % operator when dividing 3 by 2.

-- Uses AdventureWorks  
  
SELECT TOP(1) 3%2 FROM dimEmployee;
