1、实例

复制代码 代码如下:

DELIMITER //

DROP PROCEDURE IF EXISTS `test`.`p_getvalue` //

CREATE DEFINER=`root`@`localhost` PROCEDURE `p_getvalue`(

in id varchar(20),out s varchar(20)

)

begin

if (length(id)=11) then select 'A_B_C_D' into s;

elseif(length(id)=8) then select 'A_B_C' into s;

elseif(length(id)=5) then select 'A_B' into s;

elseif(length(id)=2) then select 'A' into s;

end if;

select s;

end //

DELIMITER ;

2、调用

复制代码 代码如下:

CALL p_getvalue('11000112',@S)

3、结果

'A_B_C'
