Altering database properties

This recipe shows you how to change database properties using SMO and PowerShell.

Getting ready

Create a database called TestDB by following the steps in the Creating a database recipe.

Using TestDB, we will perform the following tasks:

• Change ANSI NULLS Enabled to False

• Change ANSI PADDING Enabled to False

• Change compatibility version to 110 (SQL Server 2012)

• Restrict user access to RESTRICTED_USER

• Set the database to Read Only

How to do it...

Let's look at the steps involved in altering databases using PowerShell:

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:

   #database
   $dbName = "TestDB"
   
   #we are going to assume db exists
   $db = $server.Databases[$dbName...
