  • Getting Total Number of Rows Copied in SqlBulkCopy Using PowerShell

    calendar May 18, 2015 · 2 min read  ·
    Share on: mastodon facebook linkedin bluesky copy
    Getting the total number of inserted rows for SqlBulkCopy should be easier, but I believe the easiest (and fastest) is by using reflection and some C# code within your PowerShell script. Thanks to user601543 at stackoverflow, I was able translate his code for use within one of my own scripts. …

    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. …

    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.

    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

    calendar Feb 3, 2015 · 5 min read  ·
    Share on: mastodon facebook linkedin bluesky copy
    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

    Share on: mastodon facebook linkedin bluesky copy

    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

    calendar Jan 18, 2015 · 10 min read  ·
    Share on: mastodon facebook linkedin bluesky copy
    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 …

    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.

    Last year, I finally started working with SMO (SQL Management Objects) within PowerShell and I absolutely love it. 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.

    These SMO recipes …
