    permission As DatabasePermissionSet, _
    granteeName As String, _
    cascade As Boolean _
)
'Usage
Dim instance As Database
Dim permission As DatabasePermissionSet
Dim granteeName As String
Dim cascade As Boolean

instance.Deny(permission, granteeName, _
    cascade)

public void Deny(
    DatabasePermissionSet permission,
    string granteeName,
    bool cascade
)

public:
void Deny(
    DatabasePermissionSet^ permission, 
    String^ granteeName, 
    bool cascade
)

member Deny : 
        permission:DatabasePermissionSet * 
        granteeName:string * 
        cascade:bool -> unit 

public function Deny(
    permission : DatabasePermissionSet, 
    granteeName : String, 
    cascade : boolean
)

Parameter

  • granteeName
    Typ: System. . :: . .String
    A String value that specifies the grantee to be denied the specified set of permissions on the database.
  • cascade
    Typ: System. . :: . .Boolean
    A Boolean property that specifies whether users, to whom the grantee granted the specified set of permission, are also denied access to the specified set of permissions on the database.
    If True, the grantee and users to which the grantee granted the specified set of permissions are all denied the specified set of permissions. If False, only the grantee is denied the specified set of permissions.

Beispiele

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

'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("")
