In a ssrs 2008 r2 report, I have found the following expression and I would like you to explain the following code to me:
=IIF(Lookup(Fields!SK.Value, Fields!SK.Value, Fields!StCount.Value, "DS_StCount") = Nothing, 0, Lookup(Fields!SK.Value, Fields!SK.Value, Fields!StCount.Value, "DS_StCount"))
I know that a lookup function compares the first values to see if they are equal, and if so they value in the third column is returned. However I do not know what this enire
iif statement is doing. Can you explain it to me?

It is looking up the value in the SK column from the bound dataset to the "DS_StCount" dataset and if it does not return a value, it uses zero.

The lookup function is a bit like a left outer join in this case between the active groups dataset and "DS_StCount" on SK.value.

What do you mean by the 'bound dataset'?

mister.magoo SSC-Forever Points: 47068 More actions · Answer 3

the report item containing the formula must exist within a section off the report that is bound / linked to a dataset
