一个写着存储过程的sql文件导入出错
一个写着函数以及存储过程的sql文件把里面的内容拿出来的时候执行是没有问题的
利用 source 导入的时候会报错误为什么？？？

SQL code


use ss_l;
drop  FUNCTION  if exists `fun_get_diff`;
CREATE FUNCTION `fun_get_diff`(rid INT ,time datetime) RETURNS int(11)
    READS SQL DATA
BEGIN
    DECLARE  cost_tot  INT ;
    DECLARE  exch_tot  INT ;
    DECLARE  diff  INT;
    SELECT  IFNULL(SUM(cost_money),0) INTO cost_tot FROM  role_money_cost  
    WHERE  role_id =  rid  AND  cost_time  BETWEEN '0000-00-00 00:00:00'  AND time ;
        
    SELECT IFNULL(SUM(game_money),0)S  INTO exch_tot FROM  role_money_exch
    WHERE  role_id  = rid  AND  exch_time  BETWEEN '0000-00-00 00:00:00'  AND time ;
    
    SET diff =  exch_tot - cost_tot ; 

    RETURN diff ;
END;

错误如下：
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near '' at
line 4
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that

------解决方案--------------------
直接 mysql -uroot -pxxx < xxx.sql
------解决方案--------------------
加上 demimiter 行不？

SQL code

delimiter //
use ss_l;
drop  FUNCTION  if exists `fun_get_diff`;
CREATE FUNCTION `fun_get_diff`(rid INT ,time datetime) RETURNS int(11)
    READS SQL DATA
BEGIN
    DECLARE  cost_tot  INT ;
    DECLARE  exch_tot  INT ;
    DECLARE  diff  INT;
    SELECT  IFNULL(SUM(cost_money),0) INTO cost_tot FROM  role_money_cost  
    WHERE  role_id =  rid  AND  cost_time  BETWEEN '0000-00-00 00:00:00'  AND time ;
        
    SELECT IFNULL(SUM(game_money),0)S  INTO exch_tot FROM  role_money_exch
    WHERE  role_id  = rid  AND  exch_time  BETWEEN '0000-00-00 00:00:00'  AND time ;
    
    SET diff =  exch_tot - cost_tot ; 

    RETURN diff ;
END;
delimiter ;

------解决方案--------------------
use ss_l;
drop  FUNCTION  if exists `fun_get_diff`;
delimiter $$
CREATE FUNCTION `fun_get_diff`(rid INT ,time datetime) RETURNS int(11)
   READS SQL DATA
BEGIN
   DECLARE  cost_tot  INT ;
   DECLARE  exch_tot  INT ;
   DECLARE  diff  INT;
   SELECT  IFNULL(SUM(cost_money),0) INTO cost_tot FROM  role_money_cost 
   WHERE  role_id =  rid  AND  cost_time  BETWEEN '0000-00-00 00:00:00'  AND time ;
      
   SELECT IFNULL(SUM(game_money),0)S  INTO exch_tot FROM  role_money_exch
   WHERE  role_id  = rid  AND  exch_time  BETWEEN '0000-00-00 00:00:00'  AND time ;
  
   SET diff =  exch_tot - cost_tot ;  

   RETURN diff ;
END$$
delimiter ;

------解决方案--------------------
use ss_l;
drop  FUNCTION  if exists `fun_get_diff`;
delimiter //
