Type : System.Boolean

Notes

Most tables can support an index. However, some that cannot support an index because of the nature of the data.

Exemples

The following code example shows how to list all of the indexable tables in the AdventureWorks2012 database.

Server srv = new Server("(local)");
Database db = srv.Databases["AdventureWorks2012"];

foreach (Table tb in db.Tables) 
{
   if (tb.IsIndexable == True)
   {
      Console.WriteLine("The " + tb.Name + " table is indexable.");
   }
}

Powershell

$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$db = New-Object Microsoft.SqlServer.Management.Smo.Database
$db = $srv.Databases.Item("AdventureWorks2012")

Foreach ($tb in $db.Tables) 
{
   If ($tb.IsIndexable -eq $TRUE)
   {
      Write-Host "The" $tb.Name "table is indexable."
   }
}
