a successful application and one that creates all sorts of problems for users as well as developers. This article explores the world of error management in PL/SQL: the different types of exceptions you may encounter; when, why, and how exceptions are raised; how to define your own exceptions; how you can handle exceptions when they occur; and how you can report information about problems oracle raise exception with message back to your users. Exception Overview There are three categories of exceptions in the world of PL/SQL: internally defined, predefined, and user-defined. An internally defined exception is one that is raised internally by an Oracle Database process; this kind of exception always has an error code but does not have a name unless it is assigned one by PL/SQL or your own code. An example of an internally defined exception is ORA-00060 (deadlock detected while waiting for resource). A predefined exception is an internally defined exception that is assigned a name by PL/SQL. Most predefined exceptions are defined in the STANDARD package (a package provided by Oracle Database that defines many common programming elements of the PL/SQL language) and are among the most commonly encountered exceptions. One example is ORA-00001, which is assigned the name DUP_VAL_ON_INDEX in PL/SQL and is raised when a unique index constraint is violated. A user-defined exception is one you have declared in the declaration section of a program unit. User-defined exceptions can be associated with an internally defined exception (that is, you can give a name to an otherwise unnamed exception) or with an application-spe

Here's what I have at the end of the procedure: EXCEPTION WHEN OTHERS THEN INSERT INTO VSLogger (MESSAGE) VALUES ('Caught Exception'); This works fine, however I also want to log the error code and message. I've tried: EXCEPTION WHEN OTHERS THEN INSERT INTO VSLogger (MESSAGE) http://stackoverflow.com/questions/9184865/how-to-log-all-exceptions-in-oracle-package VALUES ('Caught Exception: Error ' || SQLCODE || ', Msg: ' || SQLERRM); But this gives me the error: 490/7 PL/SQL: SQL Statement ignored 490/100 PL/SQL: ORA-00984: column not allowed here What's the correct way to do this?

Note that Oracle 9i would let you get away with it, but that has always been the documented behavior. See here for some sample code. You could also consider wrapping this bit in an autonomous transaction, so it gets logged even if your PL/SQL code's transaction gets rolled back. share|improve this answer edited Feb 7 '12 at 22:30 answered Feb 7 '12 at 22:23 Gaius 1,5871332 Thanks! Got it working.. –Mike Christensen Feb 7 '12 at 22:39 add a comment| up vote 7 down vote Never use SQLERRM or SQLCODE. Always use dbms_utility.format_error_stack||dbms_utility.format_error_backtrace, or something similar. Exception logging without storing the line number is just cruel. share|improve this

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 pl sql error 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 w
