Subject IB_Query and "local" filtering
Author Marcin Bury

I have a IB_Query that some fields returned are "calculated" by case
expression and of course these columns have dedicated aliast.
When I want to filter this query using Filter property like
"A_CASE_COLUMN = SOME_VALUE' I'm getting exception saying that
A_CASE_COLUMN is unknown column.
Is there a way to apply local filtering other than OnFilterRecord event?
