Parámetros

permission
Tipo: Microsoft.SqlServer.Management.Smo.DatabasePermissionSet
A DatabasePermissionSet object value that specifies the set of permissions.

granteeNames
Tipo: array<System.String[]
A String array that specifies a list of grantees to be revoked access to the set of permissions.

revokeGrant
Tipo: System.Boolean
A Boolean property that specifies whether the grantee is given the ability to revoke the specified set of permissions from other users on the database.If True, the grantee is given the ability to revoke the specified set of permissions to other users on the database.If False, the grantee is not given the ability to revoke the specified set of permissions to other users on the database.

cascade
Tipo: System.Boolean
A Boolean property that specifies whether users to whom the grantee has granted the specified set of permissions are also revoked the set of permissions.If True, the grantee and users to whom the grantee granted the specified set of permission are all revoked the specified set of permissions on the database.If False, only the grantee is revoked the specified set of permissions.

asRole

Ejemplos

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

   Write-Host $spi.Grantee "has" $spi.PermissionType " permission."
}
