This solution is only available to members.

You have:
SELECT CASE
WHEN id=1 THEN 101
WHEN id=2 THEN 102
WHEN id=3 THEN 103
END
You need
SELECT CASE
WHEN id=1 THEN 101
WHEN id=2 THEN 102
WHEN id=3 THEN 103
END,
SELECT CASE
WHEN id=1 THEN 201
WHEN id=2 THEN 202
WHEN id=3 THEN 203
END
Second case will show which condition was TRUE.
In your real query 101,102,103 are your sophisticated value calculations.
201,202,203, etc - just indicators which WHEN was true.

Or for simplicity you can create a reference table with the maximum possible properties to be satisfied. Put the final string which you want to give and join your data table with this one. When it joins successfullly, you can award the value from final tilte column.
