Re: Different views with same name for different users

I found (thank you, Holger Krug) a way to do the access-problem

create view pers as select * from totaldatabase
where case currentuser="userA" then beraterid in (1256,2523,2521,623,124)
else beraterid in (9123, 12312,12313) end

(or more case statements.)

But NOW there are 2 drawbacks

1.) INSERT and UPDATE became MUCH MORE complicated. I have defined rules (do
instead insert ....), but now partial inserts (only SOME columns of the
orignal table) do not work.

2.) there is some bad performance penality. If I do a
explain select * from totaldatabase
where case currentuser="userA" then beraterid in (1256,2523,2521,623,124)
else beraterid in (9123, 12312,12313) end
allways the sequential scan is used - also that only 2% of the rows are
visible. The Planner seems not to realise, that currentuser="userA" DOES NOT
change with each row.

I think I'll ask my question in another way again..

Thank you all,

HArald
