OK so far.
3. Prior to calling IStatement.Execute, the statement type is checked.
The current (IBX) code raises an exception if the sql statement type is
isc_info_sql_stmt_select in order to stop the wrong IStatement method
being called.
Why? How is it different from SELECT returning isc_info_sql_stmt_select?
They should work the same way. Is the SQL text also parsed to detect
UPDATE and that conflicts with the returned statement type?
