Advanced SSIS Training Classes This Fall

Now that the details have been finalized, I can announce that two new SSIS classes are coming up this fall. My Linchpin People cohort Andy Leonard and I will be delivering our Advanced SSIS training class in two new locations later this year: in the Atlanta area in September, and in the Washington, DC area in December. Each of these…

How To Get Fired from an ETL Developer Job

Through the course of my 8-someodd years of building and fixing ETL processes, I’ve had the opportunity to see a lot of ETL code. Some of that code was really good, well-thought-out and carefully executed. Other load processes were – well, let’s just say that they provide plenty of consulting opportunities (and I include much of my early code in…

Office Hours Webinar: Is Biml Right for You?

If you’ve read my blog or attended one of my presentations before, you almost certainly know that I’m a huge fan of Biml. If you’re building or maintaining SSIS packages (or you’re supervising those that do), you owe it to yourself to learn about Biml. I don’t make a lot of predictions, but I will make one here: Automation tools…

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…
