group by of Oracle group sorting aggregation

A person displays a row of records, with one-time benefits and regular benefits on the same row.

A query statement is sent as follows, which is very long. Don't be frightened, there are not many things used, the essence is grouping, aggregation

 key point:

decode(t.dqflag, '1', SUM(T.AAE188)) AAE019CE，

Except for the items following the group by statement, all items that appear in the query must be aggregate functions.

Remove t.dqflag after group by,

The query becomes sum((case when t.dqflag='1' then 0 else t.aae188 end)) AAE019CE,

 

When periodic, only sum non-1  

When non-periodic, only sum non-zero.
