参数

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

granteeName
类型：System.String
A String value that specifies the grantee to be denied specified set of permissions.

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

示例

The example shows how to use the Grant 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("")

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)
