Checking index fragmentation

In this recipe, we will look at the steps to display index fragmentation using SMO and PowerShell.

Getting ready

We will investigate the index fragmentation of the Person.Person table in the AdventureWorks2008R2 database.

How to do it...

1. Open the PowerShell console by going to Start | Accessories | Windows PowerShell | Windows PowerShell ISE.

2. Import the SQLPS module and create a new SMO Server object, as follows:

   #import SQL Server module
   Import-Module SQLPS -DisableNameChecking;
   
   #replace this with your instance name
   $instanceName = "KERRIGAN"
   $server = New-Object -TypeName Microsoft.SqlServer.Management.Smo.Server -ArgumentList $instanceName

3. Add the following script and run:

   $databasename = "AdventureWorks2008R2"
   $database = $server.Databases[$databasename]
   
   $tableName = "Person"
   $schemaName = "Person" 
   
   $table = $database.Tables | 
            Where Schema -Like $schemaName |  
            Where Name -Like $tableName
