要在存储过程中设置条件,请使用以下语法-
if yourCondition then yourStatement1; else yourStatement2'; end if ; end //
让我们实现以上语法,以纠正存储过程中缺少的分号-
delimiter // create procedure Test_Demo(In inputValue int) -> BEGIN -> if inputValue=10 then -> select 'You have won 100$'; -> else -> select 'Sorry !!!'; -> end if ; -> end -> // delimiter ;
现在您可以使用CALL命令调用存储过程-
call Test_Demo(10);
这将产生以下输出-
+-------------------+ | You have won 100$ | +-------------------+ | You have won 100$ | +-------------------+ 1 row in set (0.00 sec)
