<= (Less Than or Equal To) (Transact-SQL)

[!INCLUDE sql-asdb-asdbmi-asa-pdw]

Compares two expressions (a comparison operator). When you compare nonnull expressions, the result is TRUE if the left operand has a value lower than or equal to the right operand; otherwise, the result is FALSE.

Unlike the = (equality) comparison operator, the result of the >= comparison of two NULL values does not depend on the ANSI_NULLS setting.

Transact-SQL Syntax Conventions

Syntax

expression <= expression  

[!INCLUDEsql-server-tsql-previous-offline-documentation]

Arguments

expression
Is any valid expression. Both expressions must have implicitly convertible data types. The conversion depends on the rules of data type precedence.

Result Types

Boolean

Examples

A. Using <= in a simple query

The following example returns all rows in the HumanResources.Department table that have a value in DepartmentID that is less than or equal to the value 3.

-- Uses AdventureWorks  
  
SELECT DepartmentID, Name  
FROM HumanResources.Department  
WHERE DepartmentID <= 3  
ORDER BY DepartmentID;
