[mlazdans]

	if(IBG(master_instance) && IBG(get_statement_interface)) {
		void *statement = NULL;
		if(((fb_get_statement_interface_t)IBG(get_statement_interface))(IB_STATUS, &statement, &ib_query->stmt)){
			_php_ibase_error();
			RETURN_FALSE;
		}

		if(fbu_insert_field_info(IBG(master_instance), IB_STATUS, is_outvar, num, return_value, statement)){
			_php_ibase_error();
			RETURN_FALSE;
		}
	}
