An exception can be either internally defined (by the run-time pl sql exception handling best practices 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 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). Example 11-1 calculates a price-to-earnings ratio for a company. If the company has zero earnings, the division operation raises the predefined exception ZERO_DIVIDE, the execution of the block is interrupted, and control is transferred to the exception handlers. The optional OTHERS handler catches all exceptions that the block does not name specifically. Example 11

Since I couldn't find any exact duplicate on stackoverflow, I thought I'd post it as a reference. Question: In PL/SQL, I know how to catch exceptions and execute code when they are caught, and how to propagate them to the calling block. For http://stackoverflow.com/questions/27566867/pl-sql-exception-handling-do-nothing-ignore-exception example, in the following procedure, the NO_DATA_FOUND exception is handled directly, while all other exceptions are raised to the calling block: CREATE OR REPLACE PROCEDURE MY_PROCEDURE() IS BEGIN do_stuff(); EXCEPTION WHEN NO_DATA_FOUND THEN -- Do something handle_exception(); WHEN OTHERS THEN -- Propagate exception RAISE; END; But what command should I use to ignore one or all raised exceptions and return execution control back to the calling block? oracle exception plsql exception-handling share|improve this question asked Dec 19 '14 at 13:11 silentsurfer 6691318 add a comment| 1 Answer 1 active oldest votes up vote 21 down vote accepted While I agree that 99% of the time it is bad practice to silently ignore exceptions without at least logging them somewhere, there are specific situations where this is perfectly acceptable. In these situations, NULL is your friend: [...] EXCEPTION WHEN OTHERS THEN NULL; END; Two typical situations where ignoring exceptions might be desirable are: 1) Your code contains a statement which you know will fail occasionally and you don't want this fact to interrupt your program flow. In this case, you should enclose you statement in a nested block, as the following ex

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 pl sql exception 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. 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

CONTINUE and CONTINUE WHEN Pre-11g Related articles. PL/SQL New Features and Enhancements in Oracle Database 11g Release 1 CONTINUE and CONTINUE WHEN The CONTINUE statement jumps out of the current loop iteration and starts the next one. It can be used on its own, or as part of a CONTINUE WHEN statement, as shown below. SET SERVEROUTPUT ON DECLARE l_number NUMBER := 0; BEGIN FOR i IN 1 .. 100 LOOP CONTINUE WHEN MOD(i,2) = 0; -- Do something here! l_number := l_number + 1; END LOOP; DBMS_OUTPUT.put_line('CONTINUE WHEN : ' || l_number); l_number := 0; FOR i IN 1 .. 100 LOOP IF MOD(i,2) = 0 THEN CONTINUE; END IF; -- Do something here! l_number := l_number + 1; END LOOP; DBMS_OUTPUT.put_line('IF .. CONTINUE: ' || l_number); END; / CONTINUE WHEN : 50 IF .. CONTINUE: 50 PL/SQL procedure successfully completed. SQL> Pre-11g This type of processing has always been possible using IF statements either on their own or with exceptions or GOTO statements, but the CONTINUE statement is neater and brings PL/SQL in line with other langauges. The following examples show the type of code necessary to perform the same task before the CONTINUE statement was added to PL/SQL. SET SERVEROUTPUT ON DECLARE ex_continue EXCEPTION; l_number NUMBER := 0; BEGIN FOR i IN 1 .. 100 LOOP BEGIN IF MOD(i,2) != 0 THEN RAISE ex_continue; END IF; -- Do something here! l_number := l_number + 1; EXCEPTION WHEN ex_continue THEN NULL; END; END LOOP; DBMS_OUTPUT.put_line('EXCEPTION: ' || l_number); l_number := 0; FOR i IN 1 .. 100 LOOP IF MOD(i,2) != 0 THEN -- Do something here! l_number := l_number + 1; END IF; END LOOP; DBMS_OUTPUT.put_line('IF : ' || l_number); l_number := 0; FOR i IN 1 .. 100 LOOP IF MOD(i,2) = 0 THEN GOTO label_continue; END IF; -- Do something here! l_number := l_number + 1; << label_continue >> NULL;
