Hi Kepler,
I think your question was already answered somewhere else ...
But in my opinion you have to see this like a bitmask
1 = Found in the resolver = 0000001
2 = Accessed during query processing = 0000010
4 = Found in a conditional context = 0000100
8 = Found in inner join condition = 0001000
16 = Found in outer join condition = 0010000
32 = Found in a sum node = 0100000
64 = Found in a full outer join condition = 1000000
If you find e.g.
3: means 0000011 --> Found in the resolver/Accessed during query processing
22: means 0010110 --> Accessed during query processing/Found in a conditional context/Found in outer join condition
Best regards
Helmut
