Können wir „IF NOT IN' in MySQL-Prozeduren verwenden?

if(yourVariableName  NOT IN (yourValue1,yourValue2,........N) ) then
   statement1
else
   statement2
endif    

mysql> DELIMITER //
mysql> CREATE PROCEDURE IF_NOT_INDemo(IN value int)
   ->    BEGIN
   ->       if(value NOT IN  (10,20,30) ) then
   ->          select "Value Not Found";
   ->       else
   ->          select "Value Found";
   ->       end if;
   ->    END
   -> //
Query OK, 0 rows affected (0.25 sec)
mysql> DELIMITER ;

mysql> call IF_NOT_INDemo(10);
