MySQL查询语法

Question

SELECT count(AES_DECRYPT(xyz.answertext , "aaa"))*100/(
FROM xyz 
INNER JOIN abc 
ON xyz.prim_key = abc.hhid 
INNER JOIN jkl 
ON jkl.psu = abc.psu 
WHERE columnname = 'Q08') 

我正在这上面的查询，但我得到一个错误：

#1064 - 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 'FROM xyz INNER JOIN abc ON xyz.prim_key = abc' at line 2 

请帮我解决这个问题..

Answer 1

尝试

SELECT count(AES_DECRYPT(xyz.answertext , "aaa"))*100 
FROM xyz 
INNER JOIN abc 
ON xyz.prim_key = abc.hhid 
INNER JOIN jkl 
ON jkl.psu = abc.psu 
WHERE columnname = 'Q08' 

在from之前，您有一个额外的圆括号和除法符号。如果你真的试图分裂，那么你需要划分一些东西！
