问题描述
这是真实的方式
create function getSumBSen2(@pfcode INT, @pdcode INT, @pSen INT) returns int
as
begin
declare @r int;
select
@r= sum(t2.t_shab + t2.t_rooz)
from
tbl1 t2
where
t2.FCode = @pfcode
and t2.DCode = @pdcode
and t2.sen <= @pSen;
return (@r);
end;
GO
select
t1.sen,
sum(t1.d1) as d1,
sum(t1.d2) as d2,
sum(t1.d1 + t1.d2) as d_sum,
Round((sum((1000*(t1.d1+t1.d2)+0.01)/(9500-(dbo.getSumBSen2(t1.FCode, t1.DCode, t1.sen))))),1) as SSS
from
tbl1 t1
where
t1.FCode = 81
and t1.DCode = 1
group by
t1.sen;
解决方法
如何在按部分分组的查询中使用子查询?
我使用SQL Server 2008 R2和Delphi 2010
我收到此错误:
Cannot perform an aggregate function on an expression
containing an aggregate or a sub query.
像这个查询:
select
t1.sen,sum(t1.d1)as d1,sum(t1.d2)as d2,sum(t1.d1+t1.d2) as d_sum,Round((sum((1000*(t1.d1+t1.d2))/(9500-(
select sum(t2.t_shab+t2.t_rooz)
from tbl1 t2
where FCode=81 AND DCode=1 AND t2.sen<=t1.sen
)))),1) as SSS
from
tbl1 t1
where
FCode = 81
AND DCode = 1
按t1.sen分组
