All TOraQuery components in project become editable, and can be modified by the end users.
OraQueryCompatibilityMode: boolean = False;
Before ODAC 6, TOraQuery could be editable only when InsertSQL, UpdateSQL, and DeleteSQL properties are assigned. The ability to generate update SQL statements with TOraQuery automatically was added in ODAC 6.00.0.4. Therefore, after upgrading your ODAC to the sixth version, all TOraQuery components in you project become editable, and can be modified by the end users. To restore the old behavior, set the OraQueryCompatibilityMode variable to True.
