Write Post-Query trigger for the block you want to fetch the field value for display item.

Example

Begin
   Select Ename into :datablock.dspname
      from emp
      where ecode = :datablock.ecode;
   -- Field dspname in datablock will be populated with the value
exception
   when others then
   -- you can ignore error
      null;
End;

You can write multiple plsql blocks in post-query trigger for different tables.
