備註

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

To set DatabaseRole object properties, users must have ALTER permission on the database role.

To create a database role, users must have CREATE ROLE permission on the parent database.

To drop a database role, users must have ALTER ANY ROLE permission on the parent database.

To add or remove members from the database role, users must be members of the db_owner or db_security admin fixed database role.

To grant, deny, or revoke permission on the database for other users, users must have CONTROL permission on the database role.

Thread Safety

這種類型的任何公用靜態 (在 Microsoft Visual Basic 中則為 Shared) 成員都可用於多執行緒作業。並不是所有的執行個體成員都保證可以用於所有的執行緒。

這個類型的任何公用static (在 Visual Basic 中為 Shared) 成員都是安全執行緒。不保證任何執行個體成員都可以是安全執行緒。
