Hi,

I know this is easy but I am not getting it.

Attached is the screen shot, I want that when I select an item from the LOV (cupboardno) the detail table below (which is on Books table) should be populated with the related books. I am using PRE_TEXT_ITEM trigger on the item (cupboardno) but it is not working

begin
 execute_query;
end;

Should I be doing something else? What trigger should be used for this case?

The default way to do that is:
- enter query mode
- select value from the list of values
- execute query.

What's wrong with that?

Any other way requires setting the DEFAULT_WHERE clause for that block (using the SET_BLOCK_PROPERTY built-in) which is, of course, unnecessary coding.

I'd rather keep it simple.
