Over the past few years of using datadude (aka DBPro aka Visual Studio Database Projects) I have fallen prey to a peculiar little nuance – if you forget to supply a value for a sqlcmd variable then it will simply use a default and often that is not the desired behaviour. Hence why yesterday I submitted the following suggestion to ...

My ex-colleague Paul Mcmillan pointed me at a thread on Stack Overflow that demonstrated a neat T-SQL trick to get the maximum value from a collection of columns in a row. Paul had never seen it before and neither had I so I figure one or two of you out there might learn something from it too. In short you can use the VALUES clause to effectively ...

Over the past eighteen months I have worked on four separate projects for customers that wanted to make use of Visual Studio 2010 Database projects to manage their database schema.* All the while I have been trying to take lots of notes in order that I can write the blog post that you are reading right now – a compendium of experiences and tips ...

Make SSMS start faster A couple of years ago, I blogged about some ways to make Management Studio start faster. With the latest builds of SQL Server 2012, it seems to be slower than ever, at least when starting SSMS for the first time after a reboot or install. So I've asked for them to do something in the background on Windows start-up ...

Ever since I started writing SSIS packages back in 2004 I have opted to store configurations in .dtsConfig (.i.e. XML) files rather than in a SQL Server table (aka SQL Server Configurations) however recently I inherited some packages that used SQL Server Configurations and thus had to immerse myself in their murky little world. To all the people ...

Today I had to schedule a package stored in the shiny new SSIS Catalog store that can be enabled with SQL Server 2012. (http://msdn.microsoft.com/en-us/library/hh479588(v=SQL.110).aspx) Once your packages are stored here, they will be executed using the new stored procedures created for this purpose. This is the script that will get executed if ...

One of the major criticism to DAX is the lack of a decent editor and more in general of a dedicated IDE, like the one we have for T-SQL or MDX. Well, this is no more true. On Codeplex a very interesting an promising Visual Studio 2010 extension has been released by the beginning of November 2011: http://daxeditor.codeplex.com/ Intellisense, ...

A new term - well, perhaps not that new - has come up and I’m actually very excited about it. The term is Data Scientist, and since it’s new, it’s fairly undefined. I’ll explain what I think it means, and why I’m excited about it. In general, I’ve found the term deals at its most basic with analyzing data. Of course, we all do that, and the term ...

  Yesterday a Developer at work asked for a copy of an SSIS package in Production so he could work on it (please, dear Reader – withhold judgment on Source Control – I know!). I logged on to the SSIS instance, and when I went to export the package… Oops. I didn’t have that password. The DBA who uploaded the package to Production is long ...

Last week Microsoft announced several new offerings for “Big Data” - and since I’m a stickler for definitions, I wanted to make sure I understood what that really means. What is “Big Data”? What size hard drive is that? After all, my laptop has 1TB of storage - is my laptop “Big Data”? There are actually a few definitions for this term, most ...
