Notes

To get FileGroup object properties, users can be a member of the public fixed server role.

To set FileGroup object properties, users must have ALTER permission on the database or be a member of the db_owner fixed database role.

To create a file group, users must have ALTER permission on the database or be a member of the db_owner fixed database role.

To drop a file group, users must have ALTER permission on the database or be a member of the db_owner fixed database role.

To run CheckFileGroup and CheckFileGroupDataOnly methods, users must be a member of the db_owner fixed database role or the sysadmin fixed server role.
