ABSTRACT:
In a relational database management system, errors can be corrected by an interactive user so that noninteractive operation can continue. A fetch module operates against a cursor to retrieve a record occurrence noninteractively for a selected operation. The selected operation is validated; an error condition can be set. When the selected operation is valid, the operation is performed, and a return signal is provided, causing the fetch module to retrieve the next record occurrence. When the selected operation is invalid, the fetch module responds to the error condition by operating interactively to display the previously retrieved record occurrence with an error message.
