Question

我有一个SQL查询，它给出了soem错误，说“组”未正确使用。我正在使用其中一个sql wraper creted与db2表进行交互。

有人可以指导我出了什么问题。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,

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的，您错过了CTE中的from子句。此外，您应该使用where条款而不是having进行过滤。并且group by看起来不会写（提示：聚合查询中几乎不需要select distinct）。

所以，我认为它应该是这样的：

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

你需要在这些之间有一个FROM。试试看，看看它是否有帮助。

Answer 3

您不能对GROUP BY使用distinct ...而且正如其他人所说，FROM缺失

Answer 4

您必须在SELECT语句中包含“GROUPING BY”列。您需要将P.HFAN_PARAM_TXT作为单独的列添加到Select语句

感谢大家的回答。工作解决方案（以防万一）：
