What are the best methods for generating Biml and what language should you use? Before I dive into this, let me begin with a disclaimer. I applaud anyone working with Biml to improve their productivity and eliminate needless, repetitive work. One of the primary advantages of Biml is its flexibility, which allows people to generate […]
Simply put, metadata is data about data. Probably the most common way that SQL Server Professionals use metadata is when we query SQL Server System Views. In this article we’ll discuss using metadata to drive BimlScript automation. Before I start listing common metadata sources and methods, I need to briefly contrast two basic metadata philosophies […]
If T-SQL Merge can only handle one changed record at a time, how can we use it for our initial/historical load? Further, how can we use Merge in those situations where the incremental load may produce more than 1 changed record per entity? Well, I’m glad you asked.
Welcome to the next article in the […]
This past weekend I made the trek to Oklahoma City to participate in their latest SQL Saturday. It was the first time I had spoken there, but it didn’t feel that way. Kristin Ferrier (Blog/Twitter), Jeremy Marx (Blog/Twitter), Matt Brimer (Twitter), Allen Smith (Blog/Twitter), and the rest of the team were so welcoming, just what […]
Just because you can extract every single historical record for a dimension doesn’t mean you should. In this article, we’ll cover three basic extraction “methods” and when each of them may be preferred.
As with many of my Urge to Merge Series articles, this one will be presented in layers. In this case, each layer is […]
There isn’t a lot of information on the inter webs about designing the historical load of a Data Warehouse. Consequently I see a lot of confusion on the subject. Before we go farther down the Urge to Merge Series, I thought it would be beneficial to define the concept with some visual examples.
The Initial/Historical […]
Tonight at the North Texas SQL Server User Group
This is just a quick reminder that I’m presenting another hour in my continuing series Data Warehousing for the North Texas SQL Server User Group. We’ve already covered Dimension Tables in depth, so tonight I’ll be presenting, “Fact Tables – Show Me The Money!” I’ll explain the […]
Welcome to a new series of articles, about Biml and Biml Scripting. Most of these will be fairly short personal essays about why I am investing my time in Biml Scripting. I’m hoping these will resonate with you and encourage you to start a similar journey. As I publish related articles, I will add […]
One of the most compelling reasons to learn T-SQL Merge is that it performs Slowly Changing Dimension handling so well. This post is the fourth in a series called Have You Got the Urge to Merge?. This post builds on information from the other three, so I suggest you stop and read those before continuing, […]
The Output clause, first implemented in SQL Server 2005, can be used to return information for each row modified by an Insert, Update, Delete or Merge statement. This functionality greatly increases the power and usefulness of Merge, and is required in the processing of Slowly Changing Dimensions.
This post is the second in a […]
