If Condition Evaluates to false in that case false case statement 2 block get executed.Īfter execution of the IF…ELSE statement then other unconditional statement execution remains to continue.If Condition Evaluates to true in that case true case statement 1 block gets executed.In the below-given statement IF conditional statement evaluates to true then SQL statement under IF block is executed otherwise ELSE block is executed.īelow given diagram shows how the if-else statement plays a role in executing the statement based on the expression evaluation:Ībove given flow diagram says the following things: Any T-SQL (Transact-SQL) can be placed in the conditional IF…ELSE statement. The condition should be in boolean expression, which means condition expression results must be either true or false. Use of the IF… ELSE statements can skip SQL statements on a certain condition.
