How To Install and Configure the SQL Server PowerShell Module

As a full-stack developer and Linux system administrator, I utilize PowerShell daily to automate tasks and manage infrastructure. One of the most useful PowerShell modules for me is the SQL Server module. This module allows you to manage SQL Server instances, databases, security, and more straight from the PowerShell prompt.

In this comprehensive guide, I‘ll walk you through installing, updating, and configuring the SQL Server PowerShell module on both Windows and Linux operating systems. By the end, you‘ll be equipped to harness the power of PowerShell to streamline your SQL Server administration.

Overview of Key SQL Server PowerShell Module Features

Before we dive into the installation, let‘s do a quick overview of some of the key features the SQL Server PowerShell module provides:

• SQL Instance Management – Start, stop, and configure local and remote SQL Server instance services. This allows managing instances without SQL Server Management Studio.
• Database Administration – Create, modify, backup, restore and manage databases. No need for heavy GUI tools for many tasks.
• Security Configuration – Manage logins, server roles, permissions, auditing and more.
• Query Execution – Run T-SQL statements and scripts from the PowerShell prompt.
• Task Automation – Script anything from routine maintenance to migrations.
• Multi-Platform Support – Works on both Windows and Linux SQL Server installs.

As you can see, the module unlocks SQL Server automation directly within PowerShell. Next, let‘s get it installed.

Installing the Module on Windows

Installing the SQL Server Module on Windows is straightforward using the PowerShell Gallery.

First, launch a PowerShell session as an administrator. This is required to install modules globally.

Next, run the following command:

Install-Module -Name SqlServer 

PowerShell will connect to the PowerShell Gallery repository and download the latest version of the SQL Server module and dependencies.

Once complete, you can verify installation by getting a list of available modules:

Get-Module -ListAvailable SqlServer 

You should see the SQLServer module listed along with the version number.

By default, the module installs to $env:ProgramFiles\WindowsPowerShell\Modules.

That covers the simple Windows install! Now let‘s tackle Linux.

Installing the Module on Linux

On Linux, we take advantage of PowerShell Core to install and use the SQL Server module.

First, verify you have PowerShell Core 6.0 or later installed. Run pwsh --version to check.

If needed, install PowerShell Core for Linux, macOS or Windows.

Next, launch a PowerShell Core session.

Install the SQL Server module by running:

Install-Module SqlServer

This will install the PowerShell module from the Gallery.

Verify installation:

Get-Module -ListAvailable SqlServer

By default, modules install to $HOME/.local/share/powershell/Modules on Linux.

With those simple commands, you now have the SQL Server module ready for Linux automation!

Updating to the Latest Version

Over time, updated versions of the SQL Server PowerShell module are released containing bug fixes, new functionality and support for the latest SQL Server and Windows/Linux features.

Luckily, updating is straightforward.

To update to the latest version, run:

Update-Module SqlServer

This will connect to the PowerShell Gallery and pull down the most recent production release.

You can also update to a specific version with:

Update-Module SqlServer -RequiredVersion 21.1.18102

I recommend checking the PowerShell Gallery page to view the SqlServer module versions available.

Updating regularly ensures you leverage all the latest capabilities!

Importing the SQL Server Module

With the module installed, the next step is to import it into your PowerShell session before use.

The standard way is to run:

Import-Module SqlServer 

This imports the module directly into your shell making all included cmdlets available for your scripts and one-liners!

To verify it loaded correctly, run:

Get-Module SqlServer

Now SQL Server cmdlets like Get-SqlInstance, Invoke-Sqlcmd and Backup-SqlDatabase will be ready to tackle tasks.

An alternative is to always import the module automatically on new sessions.

You can make this persistent by adding Import-Module SqlServer to your PowerShell profile.

First, check your profile status:

Test-Path $PROFILE

If False, create your profile script:

New-Item -Type File -Force $PROFILE

Next, add the import command:

"Import-Module SqlServer" | Out-File $PROFILE -Append

From now on, firing up PowerShell will auto load the SQL module!

Configure Execution Policy for Scripts

When running SQL Server PowerShell scripts, you may encounter execution policy errors blocking invocation depending on security policies.

To allow scripts to execute, set your execution police to Unrestricted.

Set-ExecutionPolicy Unrestricted

Review About Execution Policies for additional details.

Ideally, choose the least permissive policy that allows your scripts to function. For example, Bypass may suffice rather than Unrestricted depending on your environment.

Connecting to SQL Server

Many cmdlets integrate directly with available SQL Server instances. However, you can also manually establish connections.

The Connect-SqlInstance cmdlet opens a connection to a target instance.

For example, to connect to the default instance on the local server:

Connect-SqlInstance -ServerInstance localhost\DEFAULT

You can verify the active connection via Get-SqlConnection:

Get-SqlConnection

This returns a status object showing the connected instance and other details.

Connection strings also work:

Connect-SqlInstance "Server=myServerAddress;Database=myDataBase;User Id=myUsername;Password=myPassword;"

Now that you‘re connected, all subsequent SQL commands will route to the linked server instance.

Discovering SQL Server Instances

Need to scan environments to find all available SQL instances? The Get-SqlInstance cmdlet simplifies discovery.

Scan the current domain:

Get-SqlInstance -Domain

Or check a specific server:

Get-SqlInstance -ServerName MySqlServer

You can retrieve detailed information by piping to Select-Object:

Get-SqlInstance -Domain | Select-Object InstanceName,EndpointName,ServerName

Quick SQL instance visibility for inventory and automated documentation!

Key Takeaways

We covered quite a lot ground on utilizing PowerShell to manage SQL Server! Here are some key points:

• Install the SqlServer module from the PowerShell Gallery
• Update regularly to leverage the latest functionality
• Import into sessions using Import-Module SqlServer
• Connect to instances with Connect-SqlInstance
• Allow scripts with Set-ExecutionPolicy Unrestricted

The SQL Server PowerShell module unlocks infrastructure automation directly from the comfort of your prompt.

I hope you found this guide helpful for rapidly unlocking SQL management using PowerShell capabilities. PowerShell combined with SQL Server enables simplified administration and scripting to handle crucial DBA tasks.
