Is any valid expression that returns a Boolean value: TRUE, FALSE, or UNKNOWN.
Returns TRUE when both expressions are TRUE.
The following chart shows the outcomes when you compare TRUE and FALSE values by using the AND operator.
A. Using the AND operator
The following example selects information about employees who have both the title of
Marketing Assistant and more than
41 vacation hours available.
-- Uses AdventureWorks SELECT BusinessEntityID, LoginID, JobTitle, VacationHours FROM HumanResources.Employee WHERE JobTitle = 'Marketing Assistant' AND VacationHours > 41 ;
B. Using the AND operator in an IF statement
The following examples show how to use AND in an IF statement. In the first statement, both
1 = 1 and
2 = 2 are true; therefore, the result is true. In the second example, the argument
2 = 17 is false; therefore, the result is false.
IF 1 = 1 AND 2 = 2 BEGIN PRINT 'First Example is TRUE' END ELSE PRINT 'First Example is FALSE' ; GO IF 1 = 1 AND 2 = 17 BEGIN PRINT 'Second Example is TRUE' END ELSE PRINT 'Second Example is FALSE' ; GO
