given this Schema:

 table tblSET 
    SetID int  PK
    SetName nvarchar(100) 


 Table tblSetItem 
    SetID int  PK
    ItemID int PK

tblSetItem.SetID is a FK into the tblSet Table.

Some data:

tblSet

 SetID    SetName
     1    Red
     2    Blue
     3    Maroon
     4    Yellow
     5    Sky

tblSetItem

 SetID    ItemID
     1       100
     1       101
     2       100
     2       108
     2       109
     3       100
     3       101
     4       101
     4       108
     4       109
     4       110
     5       100
     5       108
     5       109

I'd like a way to identify which sets contain the same items. In the example above Red and Maroon contain the same items (100,101) and Blue and Sky contain the same values (100,108,109)

Is there a sql query which would provide this answer?
