Note that if the query SQL is invalid (such as a non existing table name 
in SELECT), I get an Access Violation instead. Did you adapt the SQL to 
your database?

On the other hand, I tested FPC 2.2.2 with Firebird (ODBC) and it gives 
the same error. However, with IBConnection instead of ODBCConnection, 
there is no error. So the error lies specifically in TODBCConnection.
