Nested aggregate?


hi -
i'm using ssrs 05 , believe trying accomplish nested aggregate. in table have expression show date difference.

=iif((sum(iif(fields!progdescr.value =

"typed",1,0)) = 1),(fields!progdt.value - fields!recvdt.value),"-")

this part working fine. trying average of field in month grouping.

any appreciated.

lee -

2008 r2 supports nested aggregates
workaround 2005 involves including first aggregate within query each row include sum of monthly grouping:

select ...., (select sum(val) foo month(dateval) = month(t.dateval))
foo t
...

ofcourse situation bit more complicated moving if-else expression sql
