The USER_DUMP_DEST initialization parameter oracle exception when others specifies the current location of the trace files. You can find the value of this parameter by issuing SHOW PARAMETER USER_DUMP_DEST. For more information about trace files, see Oracle Database Performance Tuning Guide. Compile-Time Warnings While compiling stored PL/SQL units, the PL/SQL compiler generates warnings for conditions that are not serious enough to cause errors and prevent compilation—for example, using a deprecated PL/SQL feature. To see warnings (and errors) generated during compilation, either query the static data dictionary view *_ERRORS (described in Oracle Database Reference) or, in the SQL*Plus environment, use the command SHOW ERRORS. The message code of a PL/SQL warning has the form PLW-nnnnn. For the message codes of all PL/SQL warnings, see Oracle Database Error Messages Reference. Table 11-1 summarizes the categories of warnings. Table 11-1 Compile-Time Warning Categories Category Description Example SEVERE Condition might cause unexpected action or wrong results.

How to handle general exceptions in PL/SQL up vote 0 down vote favorite I looked at Google and here but couldn't find an answer for this. I don't want to treat all exceptions in Oracle. What I want is just get the https://docs.oracle.com/database/121/LNPLS/errors.htm return code of the last statement and check if it is 0 (zero). If it is, the command was executed ok. If not, there was some error and then I want the procedure to exit and raise a message saying only that there was an error and the command that caused that error.

Is that right? –Lucas Rezende Jan 17 '14 at 12:34 1 Yes, you are right, WHEN OTHERS means that exception is raised no matter what error it is. –Yaroslav Shabalin Jan 17 '14 at 12:38 Other thing is that should I put this EXCEPTION block within BEGIN/END ?

Too often, developers focus on simply writing programs that run without errors--and ignore the impact of poorly written code upon both system performance and their ability (and their colleagues' ability) to maintain that code over time.Oracle PL/SQL Best Practices is a concise, easy-to-use reference to Feuerstein's recommendations for excellent PL/SQL coding. It answers the kinds of questions PL/SQL developers most frequently ask about their code:How should I format my code?What naming conventions, if any, should I use?How can I write my packages so they can be more easily maintained?What is the most efficient way to query information from the database?How can I get all the developers on my team to handle errors the same way?The book contains 120 best practices, divided by topic area. It's full of advice on the progra
