Data block field

Question

Hello,
i've created a data block on a table, using the wizard. that table contains some foreign keys, let's say (class_id). i wanna, on the form, not to show the id, i wanna show the name of the id corresponding to that id
so i have the tables:
A
name
surname
class_id references B(id)
B
id
denumire varchar2(30)
so when i create the data block on the table A, on class_id it's showing the id. i wanna show the "denumire" field, but i don't know hot
Regards,

Two possibilities:
1.
Create an additional textitem in your datablock, name it, lets say DSP_DENUMIRE set length and datatype according to the column in your table b, and (most important) set "database Item" to "No"
Now, create a POST-QUERY-trigger on your block to fill that field:
DECLARE
  CURSOR crLookup IS
    SELECT DENUMIRE
      FROM B
     WHERE ID=:BLOCK.CLASS_ID;
BEGIN
  OPEN crLookup;
  FETCh crLookup INTO :BLOCK.DSP_DENUMIRE;
  CLOSE crLookup;
END;2. Create a view in the database which does the join and then base your block on the view.
