I have a similar situation, but rather than a select statement, it's an update statement. I'm still VERY new to APEX and Oracle SQL. I'm used to using MS Access & VBA, but the project that was handed to me is APEX, so I'm doing my best to learn it.
Page Items:
P4_COLUMN_NAMES (Listbox)
P4_TEXT ENTRY (text field)
P4_ITEM_ENTRY (List management)
The process that should happen is this: User picks several items from ITEM_ENTRY, then chooses which column to update in COLUMN_NAMES to whatever is in TEXT_ENTRY.
Using the APEX function to cycle through the ITEM_ENTRY results, I've tried SEVERAL ways, all of which resulted in multiple errors. I've spent over a week, off and on, on this issue. Here is the most basic version.
declarev_p1_x_arr apex_application_global.vc_arr2;
begin
v_p1_x_arr := apex_util.string_to_table(:P4_ITEM_ENTRY);
for i in 1..v_p1_x_arr.count loop
UPDATE SMT SET :P4_COLUMN_NAMES = :P4_TEXT_ENTRY
end loop;
end;>
I've tried this as an app process and a page process. Until I found this thread, I didn't even know there was a PL/SQL region. ((told ya I'm a newbie)) It seems like the solution you provided to the other person is pretty close to what I'm looking for. However, I don't know how to implement it with the APEX function above.
Any help would be GREATLY appreciated!
Thanks,
