属性值

A Boolean value that specifies whether there is at least one index defined on the table.If True, there is an index defined on the table. Otherwise, False (default).

示例

The following code example shows how to check each table in the AdventureWorks2012 database to see if it has an index.

C#

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

Foreach (Table tb in db.Tables) 
{
   Console.WriteLine("The " + tb.Name + " table has an index:" + tb.HasIndex.ToString());
}

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) 
{
   Write-Host "The" $tb.Name "table has an index:" $tb.HasIndex
}
