Col level security

[mayse]

I have seen examples of how to implement row level security in Oracle. But how is col level security implemented ?

Is there a way to hide the values of certain cols from certain users using oracle supplied packages/procedures etc.. at the database level.

thanks in advance

Just create the views without the columns that you don't want users to see, then add users to a group and assign prevligious to the group.

Thanks
