Remarks

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

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

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

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