Dear Vendor: Keep My Information Secure

Dear vendor: If you’re reading this, we have done business together, either directly or indirectly. You might be a retail website from which I purchase products or services. You could be a social media empire on which I share blog posts, life events, and photos of my meals. You may be a physician’s office I visited 15 years ago. You…


The SSIS Object Variable and Multiple Result Sets

In my most recent post in this series, I talked about how to use the SSIS object variable as an ADO recordset as a source in a data flow. By loading the result set of a query into this variable, the contents of the variable can be read by an SSIS script component and sent out through the SSIS pipeline….


Somebody Doesn’t Like You, and That’s Good

Everybody wants to be liked, to some extent. Being disliked by others feels like a deficiency, a shortcoming in oneself that must be fixed. It feels like a failure that you’ve let someone down, or even worse, it can make you feel like you’re somehow broken or deficient. I would argue the opposite: It’s only a dysfunction if nobody dislikes…


Using the SSIS Object Variable as a Data Flow Source

Object variables in SSIS are incredibly versatile, allowing the storage of almost any type of data (even .NET objects). In my last post on this topic, I demonstrated how an SSIS object variable containing a .NET DataSet object could be used by the for each loop container as an iterator. In this post, I’ll continue the discussion by showing how…


Handling Mixed Format Data Files in SSIS

Some time back I wrote about how to use the script component to parse out ragged data files in SSIS. In this post, I’ll continue the discussion to describe how to handle mixed format data files – specifically, those with several different record types in each file. In a perfect world, a flat file will contain a single record type….


A full day with me, SSIS, and Edgar Allan Poe

When I think about Baltimore, I think about Edgar Allan Poe. Baltimore was Poe’s one-time home, and in fact there is a museum located in a home in which he once lived. I’ve been a Poe fan since high school, and am looking forward to seeing some of the Poe-related sights when I’m in town next month. Why am I…


On Failure: On Being a Screw-Up

“He’s a screw-up. Always trying things that don’t work.” I’ll be honest: I used to be afraid of being the person described above. I didn’t want to be known as someone whose ideas didn’t work. And to that end, I was successful: most of what I tried was successful. The bad news was that I wasn’t doing much. I was…


Null, empty string, or zero?

The answer: It Depends. One of the more common problems I encounter when managing data quality, especially in an ETL process, is the proper handling of null, empty string, or zero values. When I put on my preaching shoes to talk about bad data, this is one the areas I have to spend a lot of time covering because it…


Best of PASS Summit 2014: Building Bullet-Resistant SSIS Packages

This week, PASS announced the Best of PASS Summit 2014, a collection of the 10 highest-rated sessions from last fall’s PASS Summit in Seattle. I was pleasantly surprised to learn that my session, “Building Bullet-Resistant SSIS Packages”, was among these. All of these sessions (including lots of other content) are available for viewing on the PASS TV channel on YouTube….


Finally, a Universal Data Integration Utility

Earlier today, the fine folks at the F. Oobar Corporation released a revolutionary product: a universal data integration utility. This software component, known as the Baseline Ongoing Generic Utility for Synergy, will run on any platform and can convert data to and from almost any format automatically. It also reads the semantics of the data to determine exactly how it…
