Revoke 方法 (DatabasePermissionSet, String[], Boolean, Boolean)

从数据库的某些被授予者以及这些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。还将向这些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 DatabasePermissionSet, _
    granteeNames As String(), _
    revokeGrant As Boolean, _
    cascade As Boolean _
)
用法
Dim instance As Database
Dim permission As DatabasePermissionSet
Dim granteeNames As String()
Dim revokeGrant As Boolean
Dim cascade As Boolean

instance.Revoke(permission, granteeNames, _
    revokeGrant, cascade)

public void Revoke(
    DatabasePermissionSet permission,
    string[] granteeNames,
    bool revokeGrant,
    bool cascade
)

public:
void Revoke(
    DatabasePermissionSet^ permission, 
    array<String^>^ granteeNames, 
    bool revokeGrant, 
    bool cascade
)

member Revoke : 
        permission:DatabasePermissionSet * 
        granteeNames:string[] * 
        revokeGrant:bool * 
        cascade:bool -> unit 

public function Revoke(
    permission : DatabasePermissionSet, 
    granteeNames : String[], 
    revokeGrant : boolean, 
    cascade : boolean
)

参数

  • granteeNames
    类型：array<System. . :: . .String> [] () [] []
    一个 String 数组，该数组指定要对其撤消针对权限集的访问权限的被授权者列表。
  • revokeGrant
    类型：System. . :: . .Boolean
    一个 Boolean 属性，该属性指定是否向被授权者提供对其他用户撤消针对数据库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数据库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数据库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向其授予指定权限集的用户针对数据库的指定权限集。
    如果为 False，则只对被授权者撤消指定的权限集。

示例

The example shows how to use the Revoke method with server permissions. The method is the same for database permissions.

VB

'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

$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$arg = [Microsoft.SqlServer.Management.Smo.ServerPermission]::CreateEndpoint

$sps = new-object Microsoft.SqlServer.Management.Smo.ServerPermissionSet([Microsoft.SqlServer.Management.Smo.ServerPermission]::CreateEndpoint)
$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)
