best practices. Because you have to write those codes in hundreds of procedures and tons of code.Filtering the frm 40350 error errors and messages is the key to have a powerful message-handling. Here is an easy procedure which shows you the technique:ON-ERROR - trigger on form-levelDECLARE V_Error_Code NUMBER; V_Error_Text VARCHAR2 (2000); V_DBMS_Error_Code http://www.foxinfotech.in/2013/03/writing-onerror-trigger-oracle-forms.html NUMBER; V_DBMS_Error_Text VARCHAR2 (2000);BEGIN V_Error_Code := Error_Code; V_Error_Text := Error_Text; V_DBMS_Error_Code := DBMS_Error_Code; V_DBMS_Error_Text := DBMS_Error_Text; IF V_Error_Code IN (40401, 40405) THEN /* || 40401, 40405 - no changes to save / apply get filtered */ NULL; ELSIF V_Error_Code IN (-1034, -3114) THEN /* || -1034, -3114 - not connected to database */ Message ('Not connect to database, exiting Form'); Exit_Form (no_validate); http://talk2gerd.blogspot.com/2006/12/best-practices-on-error-and-on-message.html ELSIF V_Error_Code IN (40508, 40735) AND V_DBMS_Error_Code BETWEEN -20999 AND -20000 THEN /* || -20000 errors are raised by RAISE_APPLICATION_ERROR || They are handled in a different way */ Show_and_Log_DB_Error (V_DBMS_Error_Text); ELSE /* || All other errors went into Show_and_Log_Error, where they || get inspected, analyzed and logged. */ Show_and_Log_Error (V_Error_Code); END IF;END; 4 comments: Anonymous said...

Hi,Suppressing error messages in the on-error trigger needs to be done judiciously. Ever since a frustrating experience with a difficult bug, I start out suppressing nothing in the on-error trigger. The bug in question was something simple that would have been revealed immediately had the message not been suppressed. It is only after I am sure the form works properly in every situation (with data, without data, during edits, during validation, during navigation, dur

Solved On-Error trigger propagation from Item to Form Posted on 2004-07-12 Oracle Database 2 Verified Solutions 3 Comments 2,221 oracle forms Views Last Modified: 2013-12-11 i have this on-error trigger both on an item and form level with different error codes to handle in the two triggers . The problem i am having is that when the form issues any error in the item scope then the on-error trigger of item fires whos code is given below begin IF MESSAGE_TYPE = 'FRM'AND MESSAGE_CODE IN in oracle forms (41072 , 41076) THEN clear_list('block6.discipline_id'); clear_list('block6.academic_year'); ELSE null; END IF; end; now after the else statement i want such a code in place of " null " which could call the form level on-error trigger with the same error codes generated in the item level on-error trigger Form on-error trigger code is begin IF ERROR_TYPE = 'FRM'AND ERROR_CODE IN (40102 , 40100) THEN message(' a form level error occurs'); ELSE MESSAGE(ERROR_TYPE||'-'||TO_CHAR(ERROR_CODE)||': '||ERROR_TEXT); END IF; end; for example i m on the item and the form issues error FRM-40100 (at first record). now the on-error of item fires which does not find the code to be 41072 or 41076 transfer the control to ELSE statement which is empty (null) and doesnot cause the error to propagate to on-error trigger of form i like to have some code that could propagte the error from item to form in case if the error code does not matches to be 41072 or 41076 0 Question by:grouper15 Facebook Twitter LinkedIn Google LVL 22 Active 2 days ago Best Solution byHenka I think t
