Steve, I could have solved it, but I needed to force a Prepare of the
TIB_Query. If I force this step, I can know whether the SELECT statement has
one or more tables involved. If there's only one table, I can avoid the name
of the table in front of the field name. The thing revolves around the idea
of not forcing a prepare of the underlying TIB_Query for every editor helper
dialog.
However, for guessing OrderingItems there was no other option than to force
a prepare and hence know some field properties.
Don't fiddle with old values of fields in dialect 3. The generated syntax
(OLD_"name") is wrong and I agreed with Jason in a syntax after the initial
code for the helper dialog was created.
