多表inner join查询。
虽然看了好多,但调试还是出错。没办法,至少再次提问!
我是这样写的:
set   rs=conn.execute( "select   a.*,b.depaname,c.cityname,c.areacode   from   [ctt_users]   a   inner   join   [ctt_department]   b   on   a.userdepa=b.idexi   inner   join   [ctt_city]   c   on   a.usercity=c.id   where   a.username= ' "&username& " ' ")

调试后报告是这样的:

Microsoft   JET   Database   Engine   错误   '80040e14 '  

语法错误   (操作符丢失)   在查询表达式   'a.userdepa=b.id   inner   join   [ctt_city]   c   on   a.usercity=c.id '   中。  

UserFunc.asp,行   228  
请问哪里出了问题?

------解决方案--------------------
先在查询分析器里检查一下SQL语句是否有错!

------解决方案--------------------
set rs=conn.execute( "select a.*,b.depaname,c.cityname,c.areacode from (([ctt_users] a inner join [ctt_department] b on a.userdepa=b.idexi) inner join [ctt_city] c on a.usercity=c.id) where a.username= ' "&username& " ' ")
------解决方案--------------------
换成这样写也是可以的,试试看:
set rs=conn.execute( "select a.*,b.depaname,c.cityname,c.areacode
from [ctt_users] a,[ctt_department] b,[ctt_city] c
where a.userdepa=b.idexi and a.usercity=c.id a.username= ' "&username& " ' ")
------解决方案--------------------
刚刚少了个 "and ":
set rs=conn.execute( "select a.*,b.depaname,c.cityname,c.areacode
from [ctt_users] a,[ctt_department] b,[ctt_city] c
where a.userdepa=b.idexi and a.usercity=c.id and a.username= ' "&username& " ' ")
