MySQL的未知列變量

Question

我想寫這將接受受害者及其count.The victims 參數將包含類似這樣'123,321,222'值的程序，我使用的是函數調用 SPLIT_STR_FUNCTION分割文本分成逗號分隔值。然後我將 將每個值插入到數據庫中。

這裏是我的方法：

CREATE DEFINER=`root`@`localhost` PROCEDURE `InsertPost`(in pmsg text, in pthumbPath text, in ppath text, in puserid bigint, in count int, in victims text) 
BEGIN 
INSERT INTO posts(path,thumbpath,msg,userid) VALUES(ppath,pthumbpath,pmsg,puserid); 


SET @lastpostid = (SELECT postid FROM posts ORDER BY postid DESC LIMIT 1); 

SET @startindex=1; 

WHILE @startindex <= count DO 
SET @IndividualIDs=convert((select SPLIT_STR_Function(victims, ',', @startindex)),signed); 
SET @startindex=startindex+1;  
INSERT INTO victims(victimid,postid) VALUES(@IndividualIDs,@lastpostid); 

end WHILE; 
END 

錯誤：在字段列表 未知列的startIndex

SPLIT_STR_FUNCTION：（從here）

CREATE DEFINER=`root`@`localhost` FUNCTION `SPLIT_STR_Function`(
x VARCHAR(255), 
delim VARCHAR(12), 
pos INT 
) 

RETURNS varchar(255) CHARSET latin1 
RETURN REPLACE(SUBSTRING(SUBSTRING_INDEX(x, delim, pos), 
    LENGTH(SUBSTRING_INDEX(x, delim, pos -1)) + 1), 
    delim, '')

你的用戶變量當你增加它時，3210缺少它的@：

SET @startindex=startindex+1; 
-- Should be: 
SET @startindex = @startindex+1;
