Reorganizing/rebuilding an index

This recipe demonstrates how to reorganize or rebuild an index.

Getting ready

We will iterate through all the indexes in the Person.Person table in the AdventureWorks2014 database for this exercise.

How to do it...

Let's see how to reorganize or rebuild indexes programmatically:

1. Open PowerShell ISE as administrator.

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

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

   Add the following script and run:

   $VerbosePreference = "Continue"
   
   $databasename = "AdventureWorks2014"
   $database = $server.Databases[$databasename]
   
   $tableName = "Person"
   $schemaName = "Person"
   
   $table = $database.Tables |
            Where-Object Schema -like $schemaName |
            Where-Object Name -like $tableName
