Sql &引用；from关键字未找到"；，在子查询中使用distinct

基本上，我想做的是将值

NUM\u ORIGEN

和大小写的总和插入名为

temprecorabifinal

的表中

当我使用just

NUM\u ORIGEN

run perfect执行时，但当我添加总和时，它会显示标题中列出的错误。现在显示错误ORA-00937：没有单个组函数

Insert into SAC_IND.tempRecargaBIFINAL(NUM_ORIGEN,REC_A)
WITH
data AS
    (
    SELECT DISTINCT( NUM_ORIGEN ),
       sum(
           case
               when IDPERIODO = (2016010-5)
               then CTA_PRINCIPAL_DELTA else 0 
           end) rec_a x
    from FT_RECARGA_BI
    Where IDPERIODO BETWEEN 201604 and 2016010
    )

Select x from data
Group By x;

根据这些建议，我现在更改查询

Insert into SAC_IND.tempRecargaBIFINAL(NUM_ORIGEN,REC_A)
WITH
data AS
(
SELECT DISTINCT( NUM_ORIGEN )x,
sum(case when IDPERIODO = (2016010-5) then CTA_PRINCIPAL_DELTA else 0 end)rec_a from FT_RECARGA_BI
Where IDPERIODO BETWEEN 201604 and 2016010
)
Select x,rec_a from data
Group By x,rec_a;

终于查询工作了，我几乎哭了，但是计数给0，但是嘿！最后脚本工作：D

Insert into SAC_IND.tempRecargaBIFINAL(NUM_ORIGEN,REC_A)
WITH
data AS
(
SELECT DISTINCT( NUM_ORIGEN ) x,
sum(case when IDPERIODO = (2016010-5) then CTA_PRINCIPAL_DELTA else 0  end)rec_a from FT_RECARGA_BI
Where IDPERIODO BETWEEN 201604 and 2016010
Group by IDPERIODO,NUM_ORIGEN
)
Select x,rec_a from data
Group By x,rec_a;

在聚合函数sum中使用IDPERIODO时，您已将其放入GROUPBY子句中。那么，它总结了每个IDPERIODO和NUM_ORIGEN的CTA_PRINCIPAL_DELTA

所以查询可以有两种方式

一,

或 2.

选择

rec_a

或

x

作为别名，而不是两者都选。

distinct

不是一个函数。它始终适用于“选择”列表中的所有列。写

distinct（num_origen），…

与

distinct num_origen，…

什么是IDPERIODO=（2016010-5）？2016005带有关键字的

及其后续子查询使此任务变得非常复杂。不要在标题中添加“已解决”。如果您找到了解决方案，请添加答案并接受它。
