How to define automatic filter condition?
Hi All,
--PG8.3
--Windows 2k3 SBS
I would like to apply an automatic filter condition to a table. I create a
TEMP table at the beginning of the session to store a value to build up a
filter condition and I would like to apply this condition to every select
statement to a table during the current session.
I know that I could use views but views are read only and I also need Update
and Insert.
Could anybody turn my head to the right direction?
Thank you,
-- Csaba

You can define RULEs on insert and update on a view to do real
insert/update on the base-table.

Andreas,
thank you for your reply. Yes, I know that there is such a mathod but I read
somewhere that it is just a limited way. BTW, I am going to dig into this
more deeper.
A possible solution has come into my minde: does it have any risk to use a
read only view for selects but inserts and updates are performed on the base
table? I mean that I would select data from the view and show that
automatically filtered row set to the user but when she/he inserts or
updates a row the generated query would operate on the real (base) table.
thx,

Sure, no problem.
