Called unprepare. .. about anything else I could call. Doesn't help :)
SQL queries all built at run time
Only the inserted 'commit' via ExecSql seems to clear something
allowing the second query to work.

I don't understand why at time of the TableTwo open via it's
own designated SQL query, the TIBOQuery complains about
FieldNames missing from a SQL query on a total different
TableOne used in the same TIBOQuery
