Question

我在托管的mysql v-5.1中执行此proc时遇到问题。我找不到问题或错误。请帮帮我。

DROP PROCEDURE IF EXISTS `fetchTimeLine`;;    
CREATE PROCEDURE `fetchTimeLine`(IN `delim` int(10))    
BEGIN    
PREPARE STMT FROM     
" SELECT event_id as event,date,schedule,venue,members,descr,about,    
(SELECT src FROM photo WHERE event_id=event LIMIT 0,1) as photo1,    
(SELECT src FROM photo WHERE event_id=event LIMIT 1,1) as photo2,    
(SELECT src FROM photo WHERE event_id=event LIMIT 2,1) as photo3,    
(SELECT scr_shoot FROM videos WHERE event_id=event LIMIT 0,1) as video1,    
(SELECT scr_shoot FROM videos WHERE event_id=event LIMIT 1,1) as video2,    
(SELECT scr_shoot FROM videos WHERE event_id=event LIMIT 2,1) as video3,    
(SELECT src FROM videos WHERE event_id=event LIMIT 0,1) as vsrc1    
FROM activities    
ORDER BY date desc LIMIT ?,?; ";     

SET @START = delim;    
SET @LIMIT = 2;    
EXECUTE STMT USING @START, @LIMIT;    
DEALLOCATE PREPARE STMT;    

END;;

错误我得到了：

Answer 1

在MySQL中，date是保留字，而
你在SELECT子句中有它。试试

`date`

代替。

在ORDER BY子句中应用相同的更改。

mysql 5.1存储过程限制变量
