備註

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

To set Default object properties, users must have CREATE DEFAULT permission on the database.

To create a default, users must have CREATE DEFAULT permission on the database.

To drop a default, users must have DROP DEFAULT permission on the database.

To bind a default to a column or unbind a default from a column, users must be a member of db_owner or db_ddladmin fixed database roles.
