>= (Greater Than or Equal To) (Transact-SQL)

Compares two expressions for greater than or equal (a comparison operator).

Topic link icon Transact-SQL Syntax Conventions

expression > = expression

expression

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

When you compare nonnull expressions, the result is TRUE if the left operand has a greater or equal value than 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.

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 greater than or equal to the value 13.

USE AdventureWorks2012;
GO
SELECT DepartmentID, Name
FROM HumanResources.Department
WHERE DepartmentID >= 13
ORDER BY DepartmentID;

Here is the result set.

DepartmentID Name
------------ --------------------------------------------------
13           Quality Assurance
14           Facilities and Maintenance
15           Shipping and Receiving
16           Executive
