Oracle APEX DML 表单（无报告）不显示表中的现有数据

Question

I've been able to create APEX forms with reports and interactive grids successfully, but when I tried to just create a simple DML form, using the wizard, I get a page where I can create a row, but I can't see the existing data in the table.

This particular table always has only one row and I just need a form to update that 1 row. How can I get this view to open in update mode?

Answer 1

If you don't know ahead of time what any of the values in one of the columns, you can use ROWID as the primary key and set it to the row's ROWID in order to trigger the automatic row fetch process.

1. Create a hidden item called P1_ROWID . Its Source should be set to Database Column, ROWID .

2. On the Automatic Row Fetch process, set Primary Key Column to ROWID and Primary Key Item to P1_ROWID .

3. Create an additional process, to run before the automatic row fetch process, that executes a query like the following:

    select rowid into :P1_ROWID from mytable;
