Grant 方法 (DatabasePermissionSet, String, Boolean, String)

向被授权者授予指定的权限集，并在假定角色下向数据库的其他用户授予就权限集进行授权的能力。

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 Grant ( _
    permission As DatabasePermissionSet, _
    granteeName As String, _
    grantGrant As Boolean, _
    asRole As String _
)
用法
Dim instance As Database
Dim permission As DatabasePermissionSet
Dim granteeName As String
Dim grantGrant As Boolean
Dim asRole As String

instance.Grant(permission, granteeName, _
    grantGrant, asRole)

public void Grant(
    DatabasePermissionSet permission,
    string granteeName,
    bool grantGrant,
    string asRole
)

public:
void Grant(
    DatabasePermissionSet^ permission, 
    String^ granteeName, 
    bool grantGrant, 
    String^ asRole
)

member Grant : 
        permission:DatabasePermissionSet * 
        granteeName:string * 
        grantGrant:bool * 
        asRole:string -> unit 

public function Grant(
    permission : DatabasePermissionSet, 
    granteeName : String, 
    grantGrant : boolean, 
    asRole : String
)

参数

  • grantGrant
    类型：System. . :: . .Boolean
    一个 Boolean 属性，该属性指定是否向被授权者提供向其他用户授予针对数据库的指定权限集的能力。
    如果为 True，则向被授权者提供向其他用户授予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向其他用户授予针对数据库的指定权限集的能力。
  • asRole
    类型：System. . :: . .String
    一个 String 值，该值指定该用户在向其他用户授予针对数据库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

The example shows how to use the Grant 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)
