Exemplos

The following code example shows how to grant guest accounts permission to select table elements, and then revoke the permission with the Deny method.

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

C#

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, "Guest");

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

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, "Guest")
$tbColNames = @()
foreach ($c in $tb.Columns)
{
   $tbColNames = $tbColNames + $c.Name
   Write-Host $tbColNames
}
$tb.Deny($objPermissionSet, "Guest", $tbColNames)
