EXCEPTION
WHEN OTHERS THEN
raise_application_error(-20001,'An error was encountered - '||SQLCODE|' -ERROR- '||SQLERRM);
END;

Or you could save the error record to the table using the SQLERRM function as follows:

EXCEPTION
WHEN OTHERS THEN
err_code := SQLCODE;
err_msg := SUBSTR(SQLERRM, 1, 200);INSERT INTO audit_table (error_number, error_message)
VALUES (err_code, err_msg);
END;
