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,
-- Csaba
