  • Using Find_Alert and Show_Alert in Oracle Forms

    Show_alert is used to display model window messages in Oracle Forms and Find_alert searches the list of valid alerts in Form Builder, when the given alert is located, the subprogram returns an alert ID. You must return the ID to an appropriately typed variable, define the variable with a type of Alert.


    Example

    Show a user-warning alert. If the user presses the OK button, then make REALLY sure they want to continue with another alert.

    Declare

       al_id       alert;

       al_button   NUMBER;

    BEGIN

       al_id := FIND_ALERT ('user_warning');

     

       IF ID_NULL (al_id)

       THEN

          MESSAGE ('user_warning alert does NOT exist');

          RAISE form_trigger_failure;

       ELSE

          /*

          ** Show the warning alert

          */

          al_button := SHOW_ALERT (al_id);

     

          /*

          If user pressed OK (button 1) then bring up another alert to confirm -- button mappings are specified in the alert design

          */

          IF al_button = alert_button1

          THEN

             al_id := FIND_ALERT ('are_you_sure');

     

             IF ID_NULL (al_id)

             THEN

                MESSAGE ('the alert NAMED:are you sure ? does NOT exist');

                RAISE form_trigger_failure;

             ELSE

                al_button := SHOW_ALERT (al_id);

     

                IF al_button = alert_button2

                THEN

                   -- do some task

                   erase_all_employee_records;

                END IF;

             END IF;

          END IF;

       END IF;

    END;
