Tipo: Microsoft.SqlServer.Management.Smo.ObjectPermissionSet
An ObjectPermissionSet object value that specifies the set of permissions.

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

columnNames
Tipo: array<System.String[]
A String array value that specifies the list of columns to which the set of permissions is denied.

cascade
Tipo: System.Boolean

The following code example shows how to grant an array of grantee accounts permission to select table elements, and then revoke the permission by using the Deny method. The grantees account array is a placeholder for any array of defined user accounts.

The following database schema is used for this snippet.

//CREATE DATABASE MYTESTDB;
//GO

//USE MYTESTDB;
//GO

//CREATE TABLE TABLE1(
//    id int,
//    name varchar(32)
//);
//GO

Server srv = new Server("(local)");
Database db = srv.Databases["MYTESTDB"];

Table tb = db.Tables[0];

ObjectPermissionSet objPermissionSet = new ObjectPermissionSet(ObjectPermission.Select);
objPermissionSet.Select = true;
tb.Grant(objPermissionSet, grantees);

String[] tbColNames = new string[tb.Columns.Count];
int n = 0;
foreach (Column i in tb.Columns)
{
   tbColNames[n] = i.Name;
   n++;
}
tb.Deny(objPermissionSet, grantees, tbColNames, true);

Powershell

$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$db = New-Object Microsoft.SqlServer.Management.Smo.Database
$db = $srv.Databases.Item("MYTESTDB")
$tb = $db.Tables[0]

$objPermissionSet = new-object Microsoft.SqlServer.Management.Smo.ObjectPermissionSet([Microsoft.SqlServer.Management.Smo.ObjectPermission]::Select)
$objPermissionSet.Select = $TRUE
$tb.Grant($objPermissionSet, grantees)
$tbColNames = @()
foreach ($c in $tb.Columns)
{
   $tbColNames = $tbColNames + $c.Name
}
$tb.Deny($objPermissionSet, grantees, $tbColNames, $TRUE)
