Update Apex Tabular form with PLSQL

开发者_如何学Go

How can I update an Apex Tabular Form with pl/sql instead of using a multi-row update(MRU), is it even possible?

Thanks in advance.

Yes, it is possible. You can delete (or disable) the standard processes such as ApplyMRU, and replace them with your own PL/SQL processes to handle the tabular form arrays something like this:

for i in 1..apex_application.g_f02.count loop
   update dept
   set    dname = apex_application.g_f03(i)
   where  deptno = apex_application.g_f02(i);
end loop;

However, it isn't simple and there is a fair bit you need to know to get this right, such as:

• How the tabular form columns map to arrays like apex_application.g_f03 (view the page source and look for the names of the controls, e.g. "f03_0001").
• How some item types like checkboxes a work differently to others
• How to perform optimistic locking to prevent lost updates

There used to be a "how to" document on apex.oracle.com that described this in detail, but I haven't been able to locate it recently.
