An exception can be either internally defined (by the run-time system) or user-defined. Examples of internally defined exceptions are ORA-22056 (value string is divided by zero) and ORA-27102 (out of memory). Some common internal exceptions have predefined names, such as ZERO_DIVIDE and STORAGE_ERROR. The user defined exception in pl sql other internal exceptions can be given names. You can define your own exceptions in the declarative part of any PL/SQL block, subprogram, or package. For example, you might define an exception named insufficient_funds to flag overdrawn bank accounts. User-defined exceptions must be given names. When an error occurs, an exception is raised. That is, normal execution stops and control transfers to the exception-handling part of your PL/SQL block or subprogram. Internal exceptions are raised implicitly (automatically) by the run-time system. User-defined exceptions must be raised explicitly by RAISE statements or invocations of the procedure DBMS_STANDARD.RAISE_APPLICATION_ERROR. To handle raised exceptions, you write separate routines called exception handlers. After an exception handler runs, the current block stops executing and the enclosing block resumes with the next statement. If there is no enclosing block, control returns to the host environment. For information about managing errors when using BULK COLLECT, see Handling FORALL Exceptions (%BULK_EXCEPTIONS Attribute). Ex

WHILE indx IS NOT NULL LOOP BEGIN table_dump_csv(tableList(indx), tableList(indx) || '.csv'); EXCEPTION WHEN OTHERS THEN -- Handle/Ignore the exception as appropriate END; indx := tableList.NEXT(indx); END LOOP; Alternatively you could change the procedure into a function which returns a success/failure code. share|improve this answer answered Nov 27 '08 at 12:41 cagcowboy 18.7k65681 1 Additionally, if you want to ignore and have no program logic (e.g logging) then you'll need to add "NULL;" to the exception handler in order to get it to compile. –darreljnz Nov 28 '08 at 3:30 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting yo

Join them; it only takes a minute: Sign up Continuing Inserts in Oracle when exception is raised up vote 3 down vote favorite 1 I'm working on migration of data from a legacy system into our pl sql new app(running on Oracle Database, 10gR2). As part of the migration, I'm working on a script which inserts the data into tables that are used by the app. The number of rows of data that are imported runs into thousands, and the source data is not clean (unexpected nulls in NOT NULL columns, etc). So while inserting data through the scripts, whenever such an exception occurs, the script ends abruptly, and the whole transaction is rolled back. pl sql exception Is there a way, by which I can continue inserts of data for which the rows are clean? Using NVL() or COALESCE() is not an option, as I'd like to log the rows causing the errors so that the data can be corrected for the next pass. EDIT: My current procedure has an exception handler, I am logging the first row which causes the error. Would it be possible for inserts to continue without termination, because right now on the first handled exception, the procedure terminates execution. sql oracle exception-handling plsql share|improve this question edited Sep 30 '09 at 18:29 OMG Ponies 199k37361417 asked Jun 30 '09 at 20:21 Sathya 13.2k1667106 add a comment| 5 Answers 5 active oldest votes up vote 5 down vote accepted Using PLSQL you can perform each insert in its own transaction (COMMIT after each) and log or ignore errors with an exception handler that keeps going. share|improve this answer answered Jun 30 '09 at 20:24 Arnshea 8,56321015 The exception handler traps the first error, and then exits from the procedure. How can I keep it from exiting ? –Sathya Jun 30 '09 at 20:34 1 @Arnshea is right - put the insert inside it's own block: BEGIN insert ... EXCEPTION handle_exception END; –DCookie Jun 30 '09 at 20:59 Thanks, implemented this, and will help a lot
