    granteeNames As String(), _
    cascade As Boolean _
)
'Uso
Dim instance As Database
Dim permission As DatabasePermissionSet
Dim granteeNames As String()
Dim cascade As Boolean

    cascade)

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

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

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

    granteeNames : String[], 
    cascade : boolean
)

Parâmetros

  • granteeNames
    Tipo: array<System. . :: . .String> [] () [] []
    Uma matriz String que especifica uma lista de usuários autorizados aos quais será negado o conjunto de permissões especificado.
  • cascade
    Tipo: System. . :: . .Boolean
    Uma propriedade Boolean que especifica se os usuários, aos quais o usuário autorizado concedeu o conjunto de permissões especificado, também terão o acesso ao conjunto de permissões especificado no banco de dados negado.
    Se for True, o usuário autorizado e os usuários aos quais o usuário autorizado concedeu o conjunto de permissões especificado terão esse conjunto negado. Se False, apenas o usuário autorizado terá o conjunto de permissões especificado negado.

Exemplos

The example shows how to use the Deny method with server permissions. The method is used in the same way with 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

$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)
