Hello @ll,
there are two tables
A
Field1
Field2
Field3
Field4
Field5
B
FieldA
FieldB
FieldC
Now I would like to get the following:
Sum(A.field3) where a.field1 = condition1 and a.field2 = condition2
In the same statement I would include
Sum(b.fieldc) where b.fielda = a.field4 and b.fieldb = a.field5
It is possible without cte?
For example: select sum(a.field3) from tablea a (select sum(b.fieldc) where b.fielda = a.field4 and b.fieldb = a.field5)
A.field1 and field2 are the intern project number, b.fielda and b.fieldb are the extern ordernumber year and number.
Thank you
