This caused an error message to be generated because only a singleton

Well, all I can say is that "existing connectivity drivers do not
support this feature automagically". Is it really then intended
behaviour for Update...Returning to now return an SQL Type of
isc_info_sql_stmt_select?
Yes. What exactly call produces the error message and what exactly
is the error?
1. IAttachment.prepare is used to parse 'Update Employee Set Hire_Date =
? Where EMP_NO = ? Returning LAST_NAME'
2. IStatement.getType is then used to determine the statement type.
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.
Note that the exception is called by IBX and not Firebird. However, the
exception is consequential on Firebird returning the statement type
isc_info_sql_stmt_select when all previous versions of Firebird had
returned isc_info_sql_stmt_exec_procedure for an Update...Returning
statement.
