SQL查询给出一些错误

Question

我有一个SQL查询，它给soem错误说“组”使用不正确。 我正在使用SQL包装器之一creted来与db2表进行交互。

有人可以指导我什么是错的。我不能使用PIVOT所以试过这个。

with CTE as 
(
select distinct(P.Hfan_id)as HFAN_ID, 
Min(Case P.HFA_PARAM_NV When 'BUSI_WANT_CALL' Then P.HFAN_PARAM_TXT End) as BUSI_WANT_CALL, 
Min(Case P.HFA_PARAM_NV When 'HFAN_CHILDREN1_DT' Then P.HFAN_PARAM_TXT End) as HFAN_CHILDREN1_DT,

Select * from P1, 

S.HFAS_EMAIL, 
S.HFAS_PRIV_MOB_NR, 
Q.HFAS_ÆGTESTIL_TP, 
R.HFAN_BØRN_HJEM_AN, 
R.HFAN_TO_LÅNTAG_MK 

from CTE P1 
inner join hf.HF_ANSØGER_S Q 
on P1.hfan_id = Q.hfan_id 
inner join hf.HF_ANSØGNING_S R 
on P1.hfan_id = R.hfan_id 
inner join hf.HF_ANSØGER1_S S 
on P1.hfan_id=S.hfan_id 

错误 - “组” 未正确使用。

Answer 1

正如我在评论中提到，你缺少的CTE的from条款。另外，您应该过滤where子句而不是having。 group by看起来没有写（提示：select distinct在聚合查询中几乎不需要）。

所以，我想应该是这样的：

with CTE as (
     select P.Hfan_id, 
      . . . 
     from p 
     where P.hfan_id in (14835145, 14697134, 14697430, 14694884, 14694999, 14693122, 14693074) 
     Group by P.hfan_id 
    ) 

Answer 2

你有

select distinct(P.Hfan_id)as HFAN_ID, 
... 
(THERE SHOULD BE A FROM STATEMENT HERE) 
group by P.hfan_id, P.HFAN_PARAM_TXT, P.HFA_PARAM_NV 

你需要有一个FROM之间的那些2.尝试这一点，看看是否有帮助。

Answer 3

你不能使用GROUP BY分明......和其他人说，从丢失

Answer 4

你必须包括你是“分组依据”在SELECT语句中的列。您需要P.HFAN_PARAM_TXT添加到Select语句作为一个单独的列
