Oracle Autonomous Transactions

Using autonomous transaction for logging errors


The following procedure is a generic one which will be used to log all errors in an application to a common error log table.

CREATE OR REPLACE PROCEDURE log_errors
(
 p_calling_program IN VARCHAR2,
 p_error_code IN INTEGER,
 p_error_description IN VARCHAR2
)
IS
 PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
 INSERT INTO error_log
 VALUES
 (
 p_calling_program,
 p_error_code,
 p_error_description,
 SYSDATE,
 USER
 );
 COMMIT;
END log_errors;

The following anonymous PL/SQL block shows how to call the log_errors procedure.

BEGIN
 DELETE FROM dept WHERE deptno = 10;
EXCEPTION
 WHEN OTHERS THEN
 log_errors('Delete dept',SQLCODE, SQLERRM);
 RAISE;
END;
SELECT * FROM error_log;
CALLING_PROGRAM ERROR_CODE ERROR_DESCRIPTION
 ERROR_DATETIME DB_USER
DELETE dept -2292 ORA-02292: integrity constraint violated - child RECORD found
