Pl Sql Log Error

TECHNOLOGY: PL/SQL Tracing Lines By Steven Feuerstein Find and report your errors—by line number—in Oracle Database 10g. PL/SQL offers a powerful and flexible exception architecture. Of course, there is pl sql exception handling examples always room for improvement, and in Oracle Database 10g, exception handling takes a oracle raise exception with message big step forward with the introduction of the DBMS_UTILITY.FORMAT_ERROR_BACKTRACE function. This article explores the problem that this function solves

and how best to use it. Who Raised That Exception? When an exception is raised, one of the most important pieces of information a programmer would like to uncover is the

line of code that raised the exception. Prior to Oracle Database 10g, one could obtain this information only by allowing the exception to go unhandled. Let's revisit the error-handling behavior available to programmers in Oracle9i Database. Consider this simple chain of program calls in Listing 1: procedure proc3 calls proc2 calls proc1 , at which point proc1 raises the NO_DATA_FOUND exception. Notice that error logging in oracle stored procedure there is no error handling in any of the procedures; it is most significantly lacking in the top-level proc3 procedure. If I run proc3 in SQL*Plus, I will see the following results: ERROR at line 1: ORA-01403: no data found ORA-06512: at "SCOTT.PROC1", line 4 ORA-06512: at "SCOTT.PROC2", line 6 ORA-06512: at "SCOTT.PROC3", line 4 ORA-06512: at line 3 Code Listing 1: A stack of procedures CREATE OR REPLACE PROCEDURE proc1 IS BEGIN DBMS_OUTPUT.put_line ('running proc1'); RAISE NO_DATA_FOUND; END; / CREATE OR REPLACE PROCEDURE proc2 IS l_str VARCHAR2(30) := 'calling proc1'; BEGIN DBMS_OUTPUT.put_line (l_str); proc1; END; / CREATE OR REPLACE PROCEDURE proc3 IS BEGIN DBMS_OUTPUT.put_line ('calling proc2'); proc2; END; / This is the error trace dump of an unhandled exception, and it shows that the error was raised on line 4 of proc1. On the one hand, we should be very pleased with this behavior. Now that we have the line number, we can zoom right in on the problem code and fix it. On the other hand, we got this information by letting the exception go unhandled. In many applications, however, we work to avoid unhandled ex

We would like to know what would be the best way to log an error message when there is an error occured. Is logging to a temporary table an option? or is there a better option.

Unhandled exceptions will show up in the ADDITIONAL_INFO column. If you need notification you can poll these views and generate email. share|improve this answer answered Oct 14 '09 at 19:28 dpbradley 9,1461930 add a comment| up vote 8 down vote If you decide to roll your own logging and log into a table you might go the Autonomous Transaction route. An Autonomous Transaction is a transaction that can be commited independently of the current transaction you are in. That way you can log and commit all the info you want to your log table independently of the success or failure of your stored procedure or batch process parent transaction. CREATE OR REPLACE PROCEDURE "SP_LOG" ( P_MESSAGE_TEXT VARCHAR2 ) IS pragma autonomous_transaction; BEGIN DBMS_OUTPUT.PUT_LINE(P_MESSAGE_TEXT); INSERT INTO PROCESSING_LOG ( MESSAGE_DATE, MESSAGE_TEXT ) VALUES ( SYSDATE, P_MESSAGE_TE

I'm running into an issue here. Any advice is appreciated. I'm writing a procedure that would be used to log any errors a package may encounter and log them into the error log table I created. here is my code thus far. CREATE OR REPLACE PROCEDURE APMS.test_procedure AS procedure write_error_log (errcode number, errstr varchar2, errline varchar2) is pragma autonomous_transaction; -- this procedure stays in error logging in its own new private transaction begin INSERT INTO error_log (ora_err_tmsp, ora_err_number, ora_err_msg, ora_err_line_no) values (CURRENT_TIMESTAMP, errcode, errstr, errline); COMMIT; -- this commit does not interfere with the caller's transaction. end write_error_log; BEGIN INSERT INTO mockdata VALUES ('data1', 'mockname', 'mockcity'); exception when others then write_error_log(sqlcode,sqlerrm,dbms_utility.format_error_backtrace); raise; END test_procedure; / In the procedure I currently am using a mockdata table to induce an invalid number error and log that to the error_log table. At this point the error log table proves to be functional and inserts the data needed. The next step for me is to use this procedure to be used in the exception handlers in other programs so that the error is caught and logged to the table. Currently, my procedure is only unique to the mock_data table. My mentor/superior is telling me I need to pass this program some parameters to use it in other packages and exception handlers. I'm just having a bit of trouble. Any help would be appreciated thank you! oracle stored-procedures plsql error-handling share|improve this question asked Sep 14 '15 at 15:53 Jules 615 1 I think your procedure can be used to log an error in any scenario where mock_data table exists. You can call it from any package or exception handler to log the error. Sorry, maybe i don't understand very well your question. &
I started writing this post, it was going to be about something else. This happens occasionally, I have an idea in my head and set to work. Then I do some research - don't look so surprised, I do look at the docs occasionally - and, as in this case, I find out that there's rather more to the topic at hand than I first thought. What follows is a re-visiting of some of the tools available in Oracle to help with error logging. It includes stuff that either I'd forgotten or had never considered about some fairly common functions. Before I dive in, I'd just like to say thanks to William Robertson, who first pointed out to me the similarity between PL/SQL error logging and Quantum Theory. If you're still unclear of the connection between the two then consider, if you will, the Schrodinger's Cat Thought Experiment. It involves locking a cat in a box and possibly poisoning it. Schrodinger postulates that the cat is both alive and dead…until you open the box to check. The conclusions we can draw from this experiment are : According to Quantum Theory, the act of observation changes the nature of the thing being observed Schrodinger wasn't a Cat person Before going any further, I should point out that most of the stuff I know about Physics comes from watching Star Trek. Moving on, I now invite you to consider… Mysteriously moving errors As with cats - according to Shrodinger at least - the act of "observing"- well, handling - a PL/SQL exception changes the error ( or the location from which it originated at any rate). For example… declare l_cat number; begin l_cat := 'GREEBO'; end; / declare * ERROR at line 1: ORA-06502: PL/SQL: numeric or value error: character to number conversion error ORA-06512: at line 4 No problem with this. It shows us that the error happened at line 4 in the code, which is correct. However…. declare l_cat number; begin l_cat := 'GREEBO'; exception when others then -- d
