Handling Unexpected and Unrecoverable Errors

Go Up to Guidelines for Error Handling

Even if an error-handling routine catches and handles recoverable errors, it should always contain statements to handle unexpected or unrecoverable errors.

The following code handles unrecoverable errors:

. . .
isc_print_sqlerr(SQLCODE, isc_status);
EXEC SQL
ROLLBACK;
EXEC SQL
DISCONNECT;
exit(1);
