Revoke 方法 (ServerPermissionSet, String, Boolean, Boolean, String)

从 SQL Server 实例的某个被授权者以及该被授权者向其授予指定权限集的任何其他用户，撤消以前授予的权限。还将向该被授权者授予从假定角色中的其他用户撤消指定权限集的能力。

命名空间：  Microsoft.SqlServer.Management.Smo
程序集：  Microsoft.SqlServer.Smo（在 Microsoft.SqlServer.Smo.dll 中）

语法

声明
Public Sub Revoke ( _
    permission As ServerPermissionSet, _
    granteeName As String, _
    revokeGrant As Boolean, _
    cascade As Boolean, _
    asRole As String _
)
用法
Dim instance As Server
Dim permission As ServerPermissionSet
Dim granteeName As String
Dim revokeGrant As Boolean
Dim cascade As Boolean
Dim asRole As String

instance.Revoke(permission, granteeName, _
    revokeGrant, cascade, asRole)

public void Revoke(
    ServerPermissionSet permission,
    string granteeName,
    bool revokeGrant,
    bool cascade,
    string asRole
)

public:
void Revoke(
    ServerPermissionSet^ permission, 
    String^ granteeName, 
    bool revokeGrant, 
    bool cascade, 
    String^ asRole
)

member Revoke : 
        permission:ServerPermissionSet * 
        granteeName:string * 
        revokeGrant:bool * 
        cascade:bool * 
        asRole:string -> unit 

public function Revoke(
    permission : ServerPermissionSet, 
    granteeName : String, 
    revokeGrant : boolean, 
    cascade : boolean, 
    asRole : String
)

参数

  • revokeGrant
    类型：System. . :: . .Boolean
    一个 Boolean 属性，该属性指定是否向被授权者提供从其他用户撤消针对 SQL Server 实例的指定权限集的能力。
    如果为 True，则向被授权者提供对其他用户撤消针对 SQL Server 实例的指定权限集的能力。
    如果为 False，则不向被授权者提供对其他用户撤消针对 SQL Server 实例的指定权限集的能力。
  • cascade
    类型：System. . :: . .Boolean
    一个 Boolean 属性，该属性指定是否也对被授权者已向其授予指定权限集的用户撤消该权限集。
    如果为 True，则同时撤消被授权者以及该被授权者已向其授予指定权限集的用户访问 SQL Server 实例上的指定的权限集。
    如果为 False，则只对被授权者撤消指定的权限集。
  • asRole
    类型：System. . :: . .String
    一个 String 值，该值指定该用户在对其他用户撤消针对 SQL Server 实例的指定权限集时所充当的角色。如果被授权者属于多个角色的成员，则应使用此参数。

示例

Visual Basic

'Connect to the local, default instance of SQL Server.
Dim svr As Server
svr = New Server()
'Define a ServerPermissionSet that contains permission to Create Endpoint and Alter Any Endpoint.
Dim sps As ServerPermissionSet
sps = New ServerPermissionSet(ServerPermission.CreateEndpoint)
sps.Add(ServerPermission.AlterAnyEndpoint)
'This sample assumes that the grantee already has permission to Create Endpoints. 
'Enumerate and display the server permissions in the set for the grantee specified in the vGrantee string variable.
Dim spis As ServerPermissionInfo()
spis = svr.EnumServerPermissions(vGrantee, sps)
Dim spi As ServerPermissionInfo
Console.WriteLine("=================Before revoke===========================")
For Each spi In spis
    Console.WriteLine(spi.Grantee & " has " & spi.PermissionType.ToString & " permission.")
Next
Console.WriteLine(" ")
'Remove a permission from the set.
sps.Remove(ServerPermission.CreateEndpoint)
'Revoke the create endpoint permission from the grantee.
svr.Revoke(sps, vGrantee)
'Enumerate and display the server permissions in the set for the grantee specified in the vGrantee string variable.
spis = svr.EnumServerPermissions(vGrantee, sps)
Console.WriteLine("=================After revoke============================")
For Each spi In spis
    Console.WriteLine(spi.Grantee & " has " & spi.PermissionType.ToString & " permission.")
Next
Console.WriteLine(" ")
'Grant the Create Endpoint permission to the grantee.
svr.Grant(sps, vGrantee)
'Enumerate and display the server permissions in the set for the grantee specified in the vGrantee string variable.
spis = svr.EnumServerPermissions(vGrantee, sps)
Console.WriteLine("=================After grant=============================")
For Each spi In spis
    Console.WriteLine(spi.Grantee & " has " & spi.PermissionType.ToString & " permission.")
Next
Console.WriteLine("")

PowerShell

$sps.Add([Microsoft.SqlServer.Management.Smo.ServerPermission]::AlterAnyEndpoint)
$spis = $srv.EnumServerPermissions("vGrantee", $sps)
Write-Host "=================Before revoke==========================="
Foreach ($spi In $spis)
{
   Write-Host $spi.Grantee "has" $spi.PermissionType " permission."
}
Write-Host " "
$sps.Remove([Microsoft.SqlServer.Management.Smo.ServerPermission]::CreateEndpoint)
