Has anyone used context and fine-grained security? I seem to remember the performance hit was not minimal when using this functionality.

Add this to where clause:

group <> decode(user,'typical',380,-100)

Instead of -100 use any number not used by the groups.

Also read about contexts and grain level security.

Hi,

We have a lot of views. Now the users have a new requirement, only the user 'admin' can see all the data from the views. The user 'typical' must see all data except the one from group 380.

A basic solution is to create 2 sets of views with one set having a group number <> 380.

I'm looking for a solution to have only one set of views. It's friday afternoon and I have no inspiration :-(

TIA
