In Adaptive Server, you can use groups to grant and revoke permissions to more than one user at a time within a database. For example, if everyone who works in the Sales department needs access to certain tables, all of those users can be put into a group called “sales”. The Database Owner can grant specific access permissions to that group rather than having to grant permission to each user individually.
A group is created within a database, not on the server as a whole. The Database Owner is responsible for creating groups and assigning users to them. You are always a member of the “public” group, which includes all users on Adaptive Server. You can also belong to one other group. You can use sp_helpuser to find out what group you are a member of:
sp_helpuser user_name
