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.

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

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;

Here is the result set.

DepartmentID Name

1            Engineering
2            Tool Design
3            Sales
