Updating table w/c is not part of the block in the form

Question

Greetings!!!
I have a problem in updating table that is not part of a form's block.
This is the scenario:
Table Number 1(block in the FORM):
TABLE_A
A_ID NUMBER
A_VALUE VARCHAR2(1)
PRIMARY KEY IS A_ID
Table Number 2(Not included in the form's block and have records on it):
TABLE_B
B_ID NUMBER,
FLAG_VALUE VARCHAR2(1)
PRIMARY KEY IS B_ID
Table Number1(TABLE_A) is block in the FORM and there's a trigger PRE-UPDATE on it.
The code is:
Update TABLE_B
SET FLAG_VALUE:='T'
WHERE TABLE_B.B_ID NUMBER= :TABLE_A.A_ID NUMBER;
After adding new record in the form and the new value of A_ID is in
B_ID, the old value of FLAG_VALUE is not changed to 'T'.
CAn anybody explain to me if what's wrong...
Tnx in advance...
Regards,
BF

Answer 1

If it's a new record, PRE-UPDATE won't fire, PRE-INSERT will. Put the code in a Program Unit and call from both triggers.
