参数Arguments

permissionpermission
指定可对对称密钥授予的权限。Specifies a permission that can be granted on a symmetric key. 有关权限的列表,请参阅本主题后面的“备注”部分。For a list of the permissions, see the Remarks section later in this topic.

ON SYMMETRIC KEY ::asymmetric_key_nameON SYMMETRIC KEY ::asymmetric_key_name

TO <database_principal>TO <database_principal>
指定要向其授予权限的主体。Specifies the principal to which the permission is being granted.

WITH GRANT OPTIONWITH GRANT OPTION
指示该主体还可以向其他主体授予所指定的权限。Indicates that the principal will also be given the ability to grant the specified permission to other principals.

AS <database_principal> 指定一个主体,执行该查询的主体从该主体获得授予该权限的权利。AS <database_principal> Specifies a principal from which the principal executing this query derives its right to grant the permission.

Database_user_mapped_to_Windows_GroupDatabase_user_mapped_to_Windows_Group
指定映射到 Windows 组的数据库用户。Specifies a database user mapped to a Windows group.

Database_user_mapped_to_certificateDatabase_user_mapped_to_certificate
指定映射到证书的数据库用户。Specifies a database user mapped to a certificate.

Database_user_mapped_to_asymmetric_keyDatabase_user_mapped_to_asymmetric_key
指定映射到非对称密钥的数据库用户。Specifies a database user mapped to an asymmetric key.

Database_user_with_no_loginDatabase_user_with_no_login
指定无相应服务器级主体的数据库用户。Specifies a database user with no corresponding server-level principal.

RemarksRemarks

可以在 sys.symmetric_keys 目录视图中查看对称密钥的有关信息。Information about symmetric keys is visible in the sys.symmetric_keys catalog view.

对称密钥是一个数据库级的安全对象,包含于权限层次结构中作为其父级的数据库中。A symmetric key is a database-level securable contained by the database that is its parent in the permissions hierarchy. 下表列出了可授予的对对称密钥最为具体的限定权限,以及隐含这些权限的更为通用的权限。The most specific and limited permissions that can be granted on a symmetric key are listed in the following table, together with the more general permissions that include them by implication.

权限Permissions

授权者(或用 AS 选项指定的主体)必须具有带 GRANT OPTION 的相同权限,或具有隐含所授予权限的更高权限。The grantor (or the principal specified with the AS option) must have either the permission itself with GRANT OPTION, or a higher permission that implies the permission being granted.

若要使用 AS 选项,还必须满足以下附加要求:If you are using the AS option, the following additional requirements apply.

AS granting_principalAS granting_principal 所需的其他权限Additional permission required
数据库用户Database user 对用户的 IMPERSONATE 权限、db_securityadmin 固定数据库角色的成员身份、db_owner 固定数据库角色的成员身份或 sysadmin 固定服务器角色的成员身份。IMPERSONATE permission on the user, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
映射到 Windows 登录名的数据库用户Database user mapped to a Windows login 对用户的 IMPERSONATE 权限、db_securityadmin 固定数据库角色的成员身份、db_owner 固定数据库角色的成员身份或 sysadmin 固定服务器角色的成员身份。IMPERSONATE permission on the user, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
映射到 Windows 组的数据库用户Database user mapped to a Windows group Windows 组的成员身份、db_securityadmin 固定数据库角色的成员身份、db_owner 固定数据库角色的成员身份或 sysadmin 固定服务器角色的成员身份。Membership in the Windows group, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
映射到证书的数据库用户Database user mapped to a certificate db_securityadmin 固定数据库角色的成员身份、db_owner 固定数据库角色的成员身份或 sysadmin 固定服务器角色的成员身份。Membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
映射到非对称密钥的数据库用户Database user mapped to an asymmetric key db_securityadmin 固定数据库角色的成员身份、db_owner 固定数据库角色的成员身份或 sysadmin 固定服务器角色的成员身份。Membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
未映射到任何服务器主体的数据库用户Database user not mapped to any server principal 对用户的 IMPERSONATE 权限、db_securityadmin 固定数据库角色的成员身份、db_owner 固定数据库角色的成员身份或 sysadmin 固定服务器角色的成员身份。IMPERSONATE permission on the user, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
数据库角色Database role 对角色的 ALTER 权限、db_securityadmin 固定数据库角色的成员身份、db_owner 固定数据库角色的成员身份或 sysadmin 固定服务器角色的成员身份。ALTER permission on the role, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.
应用程序角色Application role 对角色的 ALTER 权限、db_securityadmin 固定数据库角色的成员身份、db_owner 固定数据库角色的成员身份或 sysadmin 固定服务器角色的成员身份。ALTER permission on the role, membership in the db_securityadmin fixed database role, membership in the db_owner fixed database role, or membership in the sysadmin fixed server role.

对某安全对象具有 CONTROL 权限的主体可以授予对该安全对象的权限。Principals with CONTROL permission on a securable can grant permission on that securable.

被授予 CONTROL SERVER 权限的用户(例如,sysadmin 固定服务器角色的成员)可以授予对相应服务器中任一个安全对象的任意权限。Grantees of CONTROL SERVER permission, such as members of the sysadmin fixed server role, can grant any permission on any securable in the server. 将某一数据库的 CONTROL 权限授予用户(例如,db_owner 固定数据库角色的成员)后,该用户就可授予对该数据库中任何一个安全对象的任意权限。Grantees of CONTROL permission on a database, such as members of the db_owner fixed database role, can grant any permission on any securable in the database.

示例Examples

以下示例授予数据库用户 ALTER 对对称密钥 SamInventory42HamidS 权限。The following example grants ALTER permission on the symmetric key SamInventory42 to the database user HamidS.

USE AdventureWorks2012;  
GRANT ALTER ON SYMMETRIC KEY::SamInventory42 TO HamidS;  
GO
