one of the easiest is manipulating the :system.message_level:KEY-COMMIT - trigger on form-level (quick and dirty)BEGIN :System.Message_Level := 25;
Frm 40350 Error
COMMIT; :System.Message_Level := 5;END;or KEY-COMMIT - triggerDECLARE V_Message_Level NUMBER;BEGIN V_Message_Level := frm-40301 :System.Message_Level; :System.Message_Level := 25; COMMIT; :System.Message_Level := V_Message_Level;END;these are not best practices. Because you have to fnd_message.show in oracle forms write those codes in hundreds of procedures and tons of code.Filtering the errors and messages is the key to have a powerful message-handling. Here is an http://www.foxinfotech.in/2013/03/writing-onerror-trigger-oracle-forms.html 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 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 */ http://talk2gerd.blogspot.com/2006/12/best-practices-on-error-and-on-message.html 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); 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... Hello sir,I tried the same code in on-error trigger in forms but showing me compilation errorthe identifier'Show_and_Log_DB_Error 'and Show_and_Log_Error'must be declared January 16, 2008 Gerd Volberg said... that's correct.
