SQL SERVER CE子查询异常

Question

下面是我想要执行的子查询，但VC＃2010在执行时会生成异常。

查询：

("SELECT U.Name 
  FROM Users U,Installments I 
  WHERE U.ID=I.ID 
  AND I.Sr=(SELECT MAX(Sr) FROM Installments Group By ID ) 
  AND I.Date=(SELECT Date FROM Installments GROUP BY ID HAVING(Sr=Max(Sr)))"
 , Con))

例外：

  

解析查询时出错[令牌行号= 1，令牌行偏移= 69令牌错误=选择]

Answer 1

您的查询不应该是SELECT U.Name FROM Users AS U,Installments AS I WHERE U.ID=I.ID AND I.Sr=(SELECT MAX(Sr) FROM Installments Group By ID ) AND I.Date=(SELECT Date FROM Installments GROUP BY ID HAVING(Sr=Max(Sr)))吗？您没有将表格指定为U和I，只是将字母放在表格名称之后。
