列在 select 列表中无效，因为它不包含在聚合 function 或 GROUP BY 子句 SQL 服务器中

Question

这是我的查询：

SELECT r.CALLID  AS MultiRES,
c.CallDate AS CallDate,
cr.Institution AS Institution,
cr.Branch AS Branch
FROM tblResolution r
INNER JOIN tblcall c ON c.CallID=c.CallID AND c.CallDate=c.CallDate
INNER JOIN tblCaller cr ON cr.Institution = cr.Institution AND cr.Branch=cr.Branch
GROUP BY r.CALLID HAVING COUNT(*) > 1;

但是当我运行它时出现错误，我知道我需要用 group by 子句做一些事情，我只是不知道把它放在哪里。

编辑：刚刚弄清楚出了什么问题：

SELECT r.CALLID  AS MultiRES,
c.CallDate AS CallDate,
cr.Institution AS Institution,
cr.Branch AS Branch
FROM tblResolution r
INNER JOIN tblcall c ON c.CallID=c.CallID AND c.CallDate=c.CallDate
INNER JOIN tblCaller cr ON cr.Institution = cr.Institution AND cr.Branch=cr.Branch
GROUP BY c.CallDate,cr.Institution,cr.Branch, r.CALLID HAVING COUNT(*) > 1;

Answer 1

select 子句中的所有内容都需要在 group by 子句中，除非它是聚合 function（例如count或sum ）：

SELECT r.CALLID  AS MultiRES,
c.CallDate AS CallDate,
cr.Institution AS Institution,
cr.Branch AS Branch
FROM tblResolution r
INNER JOIN tblcall c ON c.CallID=c.CallID AND c.CallDate=c.CallDate
INNER JOIN tblCaller cr ON cr.Institution = cr.Institution AND cr.Branch=cr.Branch
GROUP BY r.CALLID, c.CallDate, cr.Institution, cr.Branch
HAVING COUNT(*) > 1;
