For pl sql raise exception example: DECLARE ex_custom EXCEPTION; BEGIN RAISE ex_custom; EXCEPTION WHEN ex_custom THEN DBMS_OUTPUT.PUT_LINE(SQLERRM); END; / The output is "User-Defined Exception". Is it possible to change that message? EDIT: Here is some more detail. I hope this one illustrates what I'm trying to do better. DECLARE l_table_status VARCHAR2(8); l_index_status VARCHAR2(8); l_table_name VARCHAR2(30) := 'TEST'; l_index_name VARCHAR2(30) := 'IDX_TEST'; ex_no_metadata EXCEPTION; BEGIN BEGIN SELECT STATUS INTO l_table_status FROM USER_TABLES WHERE TABLE_NAME = l_table_name; EXCEPTION WHEN NO_DATA_FOUND THEN -- raise exception here with message saying -- "Table metadata does not exist." RAISE ex_no_metadata; END; BEGIN SELECT STATUS INTO l_index_status FROM USER_INDEXES WHERE INDEX_NAME = l_index_name; EXCEPTION WHEN NO_DATA_FOUND THEN -- raise exception here with message saying -- "Index metadata does not exist." RAISE ex_no_metadata; END; EXCEPTION WHEN ex_no_metadata THEN DBMS_OUTPUT.PUT_LINE('Exception will be handled by handle_no_metadata_exception(SQLERRM) procedure here.'); DBMS_OUTPUT.PUT_LINE(SQLERRM); END; / In reality, there are dozens of those sub-blocks.

(APEX 4.1.1) planetthoughtful Jun 23, 2014 11:49 PM Hi All,Is there a way to raise a validation error (or something that looks exactly like a validation error) in a PL SQL Anonymous Block in the Processing section of a page?I have a situation that I don't think is possible for me to trap via normal validations, but I https://community.oracle.com/thread/3575929 can definitely test the outcome in my processing block.If the outcome 'failed', I'd like to bounce the page back with what looks exactly like a validation error.Is this possible in APEX 4.1.1?Many thanks,pt I have the same question Show 0 Likes(0) 3338Views Tags: none (add) plsqlContent tagged with plsql, validationContent tagged with validation This content has been marked as final.

Use the APEX_ERROR.ADD_ERROR procedure. An example: apex_error.add_error( p_message => 'my error message', p_additional_info => null, p_display_location => apex_error.c_inline_in_notification ); Kind regards,Nick Like Show 2 Likes(2) Actions 2. Re: Raise a validation error in Processing PL / SQL? (APEX 4.1.1) Tom Petrus Jun 24, 2014 5:27 AM (in response to planetthoughtful) Why would a validation of the plsql type not work? You could just associate it with the page instead of an item, and use a plsql function returning a boole
different. They're plenty of examples online about raising and handling exceptions on the web, but one thing you may not have realized is how PL/SQL propagates http://www.talkapex.com/2012/09/plsql-exceptions-propagation-during.html exceptions that occur in the variable declaration section of a procedure. In http://blog.whitehorses.nl/2010/04/15/handling-ora-errors-in-apex/ the first example I created a procedure that has a variable, l_var, which can handle one character. As expected, when I assign more then one character an exception is raised and is propagated to the EXCEPTION block of the procedure. SQL> CREATE OR REPLACE PROCEDURE sp_test(p_var pl sql in varchar2) 2 AS 3 l_var VARCHAR2(1); 4 BEGIN 5 dbms_output.put_line('***START***'); 6 l_var := 'abc'; 7 exception 8 WHEN others THEN 9 dbms_output.put_line('***Exception***'); 10 raise; 11 END sp_test; 12 / Procedure created. SQL> exec sp_test(p_var => 'abc'); ***START*** ***Exception*** BEGIN sp_test(p_var => 'abc'); END; * ERROR at line 1: ORA-06502: PL/SQL: numeric or value error: character string buffer pl sql raise too small ORA-06512: at "ODTUG.SP_TEST", line 10 ORA-06512: at line 1 In the next example, instead of assigning the value in the main block of code I assigned the value in the declaration section. You'll notice that the procedure doesn't even get to the "START" line nor is the exception handled in the procedure's exception block. Instead the exception is propagated to the calling process right away. SQL> CREATE OR REPLACE PROCEDURE sp_test(p_var in varchar2) 2 AS 3 l_var VARCHAR2(1) := p_var; 4 BEGIN 5 dbms_output.put_line('***START***'); 6 exception 7 WHEN others THEN 8 dbms_output.put_line('***Exception***'); 9 raise; 10 END sp_test; 11 / Procedure created. SQL> exec sp_test(p_var => 'abc'); BEGIN sp_test(p_var => 'abc'); END; * ERROR at line 1: ORA-06502: PL/SQL: numeric or value error: character string buffer too small ORA-06512: at "ODTUG.SP_TEST", line 3 ORA-06512: at line 1 Before you go and change any of your existing code based on this article, I'm not saying that you should avoid defining variables in the declaration section of a procedure. Instead, just be aware of
comments Tweet One of the first things I noticed when making an APEX application, there was a lack of error handling. In particular, the error handling raised from an database procedure. For clarity, here a part of a screen as you will see after a unique constraint violation, the ORA-0001 error. I think the most horrible part is that this error is displayed on a new page! Errors like these must be displayed on the same page where the error occured, on top of the page, in the #NOTIFICATION_MESSAGE# area, the same way as page processing validation is displayed. Here a preview of the final result. This of course can be achieved by adding an extra page process validation. Page process validation is to be conducted before the page procesess. Major disadvantage of this solution is that all business rules which are implemented in the database, must be defined as a page process validation on each APEX page. Moreover, if we adding a business rule on the database, we must not forget to add an extra process validation on a ore more APEX pages. Make sure that all errors are handled by one procedure (a good habit anyway). something like this: exception when others then omp_log.error(sqlcode,sqlerrm); end ins; In this procedure, we test of this error has occurred in an APEX environment. If so, we DON'T raise this as a application error. Moreover, we remember through a package variable that an error has occurred which had not been raised. if v('APP_SESSION') is null then pv_set_unraised_error_exists := false; raise_application_error(sqlcode,sqlerrm); else -- context is APEX pv_set_unraised_error_exists := true; -- save the omp_nos.ins(sqlerrm); end if; We also save the error occurred in a temporary table. We must do that with an autonomous transaction so that the errors are actually recorded in the temporary table. We
