问题 Using Oracle APEX 4.2, I have a page process that uses DBMS_ALERT for a running process that may take up to a minute to complete or fail. While this is running, through the use of a trigger, there is a DBMS_ALERT.signal posting notifications of progress. My question is, within Oracle APEX 4.2, how can I display to the user, a running progress of these notifications from DBMS_ALERT, within a region or modal on the page? I need to provide the user all these alerts as the job is running until it

问题 I have seen in this application a popup windows with a form inside. Can anyone help me build a popup windows like that, or if there is any tutorial where I can see how it's done. 回答1: There are some modal form plug-ins like this one on Apex-Plugin.com. I haven't used them myself so cannot vouch for them. Alternatively, use your browser's "View Source" function on the Apex page you like and you will see all the function definitions and where they are called. It appears to just be using the

问题 I'm having an issue binding the value of a page item to a declared variable in an anonymous PL/SQL block process. The problem is that the page item (:P4550_REQUESTOR) is not populated with a value until a conditional is met. It appears that the PL/SQL block process is binding the variable to an empty value as soon as the page is loaded, despite the fact that the process does not fire until a specific button has been clicked. Here is my code: DECLARE v_email_to app_user.email%type; v_requestor

问题 I have a set of text Field items in Oracle Apex: Order Number Revision Number When we open the report, revision should be hidden. Only when the user enters unique order number (non-duplicate order numbers), revision number should be visible. If he enters duplicate order number, revision number should be hidden. 回答1: A simple (though not bullet-proof) solution is to create a Dynamic Action on the Order Number item that, when Changed, issues a query on the database to check if the order number

问题 I have created a table in APEX that has a PK that is incremented by a SQL sequence: CREATE SEQUENCE seq_increment MINVALUE 1 START WITH 880 INCREMENT BY 1 CACHE 10 This seems to work perfectly. The issue is that sometimes, usually when I get on in the morning and run a process to enter a new row, it skips a bunch of numbers. I only care because these numbers are being used as the ID# of documents in my company and losing/skipping blocks of numbers is not going to be acceptable when this tool

问题 In Oracle APEX, how do I prevent a user from navigating back to the login page from the home page using browser back button after login, and then navigating back to home page from the login page after logout?

问题 I am using a dynamic action to auto fill data into fields based on the ID of a person that is being pulled from another table (which pulls the person's dept, employee#, etc). This works fine if I leave the auto populated fields editable, but I want these fields to be 'display only' so that the person entering the data cannot edit it. That's the whole reason for using dynamic action. When I set the fields to 'display only', the data never gets saved to the table so the fields are blank when I

问题 Environment: Oracle APEX v5.1.2 / Oracle 12c I have an interactive grid report by where I have one field that is a display only column but it actually returns an error message description that could be quite long. Since I would like to keep my IG report to one record per row, is there a means of being able to display the full contents of this field without allowing changes to the underlying column value in the database? Some means of a tool tip or being able to drill into the field to view
