  • Simplifying SQL Server Migrations using PowerShell

    May 15, 2015 · 1 min read  ·
    Share on:

    Recently, I did a webcast for the PowerShell Virtual Chapter of PASS on Simplifying SQL Server Migrations using PowerShell. If you're planning for a SQL Server migration, I wrote a bunch of scripts that can help, and put them all on github. Check out the sqlmigration repository, and the accompanying PowerPoint Slides. …

    Share on:

    I just released a new PowerShell script, Get-SQLServerKeys.ps1. The script works works with several versions of SQL Server (2005-2014), and can use Central Management Server, a text file, or just a string of servers as input. Like many of the Windows Key scripts available, this one relies on Remote Registry being …

    Share on:

    I'm currently attending Regis University for my grad degree, and just finished up a networking class. For my final, I chose to explore the Windows Net.TCP Port Sharing Service. I had this glorious vision of translating some C# code to 100% PowerShell code, but eventually gave into the fact that PowerShell doesn't …

  • Using .NET DataTable Computes and Column Expressions in PowerShell

    Feb 3, 2015 · 5 min read  ·
    Share on:

    As a SQL Server DBA, I'm used to SQL being able to perform aliasing, super fast subselects, and easy aggregation. My most recent project, Invoke-Locate.ps1, however, uses SQLite because of its portability and speed when performing simple selects and inserts. The downside is that SQLite doesn't handle some subselects …

  • Find Duplicates in PowerShell Datatable using LINQ

    Jan 21, 2015 · 3 min read  ·
    Share on:

    Update 1/4: Removed conversion of datatable to list. That just wasted memory, as this works on all enumerables. I don't have a practical application for this method, but I wanted to figure out how to do it anyway. Doing so was frustrating but kinda fun. It forced me to learn about lamdas in PowerShell which I'll …

  • High-Performance Techniques for Importing CSV to SQL Server using PowerShell

    Jan 18, 2015 · 10 min read  ·
    Share on:

    If you've ever tried to use PowerShell's Import-CSV with large files, you know that it can exhaust all of your RAM. Previously, I created a script on ScriptCenter that used an alternative technique to import large CSV files, and even imported them into SQL Server at a rate of 1.7 million rows a minute. I've now gotten …

    Jan 16, 2015 · 5 min read  ·
    Share on:

    Update 1/18/2015: This native PowerShell script can process over 165,000 rows a second. I'm so pumped. My million row CSV with 9k dupes processed in 6.4 seconds. I actually tried this using LINQ in PowerShell, but it seemed exponetially slower as the dataset grew. A user on reddit's PowerShell subreddit asked for the …

Below are a few recipes that I created and use extensively throughout my SQL Management scripts, which you can find on ScriptCenter. Some recipes show more than one way to perform a task.

    Share on:

    While researching how connect to a detached MDF and read the internal file structure of the internal files, including LDF files, I kept seeing suggestions for using the undocumented DBCC command DBCC checkprimaryfile. Initially, my code looked like this: 1# SQL Server is required to read the file contents 2$servername …
