Question on Updatable View!

I have a view based on two tables joined by the id of a parent table with the same id as a foreign key in the child table. This is the select statement for my view.

Code:

---

SELECT L.AGENT_NUM, L.SCAC, L.LOI_DATE, L.LOI_REPL_DATE, F.AREA, L.LOI_CANCEL_DATE,
L.BOOKING_AGENT, L.GBLOC
FROM LOI_AUTHORITY L, FP_AREAS F
WHERE L.FP_AREA_ID = F.ID

---

This is the select on data dictionary to see what rows of views have update, insert and deletes.

Code:

---

  1  SELECT column_name, updatable, insertable, deletable
  2  FROM user_updatable_columns
  3*  WHERE table_name = 'LOI_FP_AREAS_VIEW'
oracle@CVLPL> /

COLUMN_NAME                    UPD INS DEL
------------------------------ --- --- ---
AGENT_NUM                      YES YES YES
SCAC                              YES YES YES
LOI_DATE                        YES YES YES
LOI_REPL_DATE                YES YES YES
AREA                              NO  NO  NO
LOI_CANCEL_DATE            YES YES YES
BOOKING_AGENT              YES YES YES
GBLOC                            YES YES YES

8 rows selected.

My question is when I use the view in my Oracle Forms 6i and try to do an update it does not allow me. I'm using Oracle 8i on windows NT. Does anyone has any clue as to what I am missing? Thanks.

What error exactly?

Forms may be trying to update the entire row which I doubt would be allowed because you have non-updateable columns.

Have a look at the Block Property "Update Changed Columns Only".

Yes. You're right padders. When I took off the AREA field of parent and added the foreign key of child table in my view instead, it let me allowed to do an update and now I can use the foreign key to do a join. I had to create another data block to do a join between the foreign key in child and that parent data block. Since, I have a tabular style form it's not query for all the rows only for the first one.

Anyways, I deleted the block to get the area and then had to write a select in POST-QUERY Trigger to get the value for each row. I know it's confusing but I'm just trying to do my best. If someone has a better way please let me know. Thanks.

P.S. Thanks man. Changing the UPDATE CHANGED COLUMN ONLY PROPERTY ON BLOCK allows me to do an update.
