SQL Server 2014 with Powershell v5 Cookbook

By: Donabel Santos

Overview of this book

PowerShell can be leveraged when automating and streamlining SQL Server tasks. PowerShell comes with a rich set of cmdlets, and integrates tightly with the .NET framework. Its scripting capabilities are robust and flexible, allowing you to simplify automation and integration across different Microsoft applications and components. The book starts with an introduction to the new features in SQL Server 2014 and PowerShell v5 and the installation of SQL Server. You will learn about basic SQL Server administration tasks and then get to know about some security-related topics such as the authentication mode and assigning permissions. Moving on, you will explore different methods to back up and restore your databases and perform advanced administration tasks such as working with Policies, Filetables, and SQL audits. The next part of the book covers more advanced HADR tasks such as log shipping and data mirroring, and then shows you how to develop your server to work with BLOB, XML, and JSON. Following on from that, you will learn about SQL Server's BI stack, which includes SSRS reports, the SSIS package, and the SSAS cmdlet and database. Snippets not specific to SQL Server will help you perform tasks quickly on SQL servers. Towards the end of the book, you will find some useful information, which includes a PowerShell tutorial for novice users, some commonly-used PowerShell and SQL Server syntax, and a few online resources. Finally, you will create your own SQL Server Sandbox VMs. All these concepts will help you to efficiently manage your administration tasks.

Getting history

You can recall the commands you typed in the PowerShell console using the Get-History cmdlet.

How to do it...

This is how to redisplay the console history:

  1. Open PowerShell ISE as an administrator.
  2. Run the following command:
    Get-History
    

How it works...

By default, PowerShell will keep 64 previous commands in the buffer and allow you to recall these commands when you run Get-History. The Get-History command will display the last 32 commands, but you can also specify how many lines you want to display by specifying the –Count parameter:

#get last 10
Get-History –Count 10

If you want to reexecute any of the commands that you see in your history, you can use the Invoke-History cmdlet and provide it with the history ID. For example, if you want to re-execute ID 7, you can use the following command:

Invoke-History –ID 7
