DAX Studio 2.0 is out the door

Learning to write DAX queries is important in the new world of tabular data models. DAX Studio is the best environment right now for learning to write and test DAX queries.

Today Darren Gosbell announced on his blog that version 2.0 of DAX Studio is out the door. This is a superb effort and one that you should both applaud and use.

The biggest improvements seem to be around the UI. It looks very impressive but there is much more to it than just the UI.

Microsoft Action Figures–SQL Server and Heroes

I’ve ended up with a number of Microsoft figurines over the years. It all started with Nine Guy, then went on to the whole Source Force team:

It’s been interesting to see how they’ve evolved over the years. Here are the SQL Server ones:

SQL Server 2005 had a demure little lady that was all Red. She morphed into an orange version by SQL Server 2008 (shown here with me at TechEd USA) in 2008. Later she took on a Neo look from the Matrix, and now there’s a guy, the Query Controller.

It’s on at the BHP offices at 125 St Georges Terrace. If you are coming, please ping Jenny to let her know.

I look forward to seeing many of you there.

Rett Syndrome Research needs help

Very proud of my daughters this week. As some of you will know, one of my daughters has Rett syndrome. It’s a rare chromosomal disorder that basically only impacts girls. (Boys can get it but they usually do not survive long after birth). Girls develop fairly normally up to about 12 to 18 months of age, then regress markedly. As it affects only about 1 in 10,000 girls, it’s not the sort of thing that gets much research funding.

Allowing specific non-sysadmin users to query group membership for a login

I had a lot of good feedback about my post the other day about how to query group membership for a given login.

One tricky question was about how you could let a specfic user be able to find the group membership for another login, without the user being a sysadmin to run the code. Doing that is a bit trickier but can be done by creating a certificate, a login from the certificate, then assigning permissions to that login, and finally applying a digital signature to the procedure using the certificate.

Identifying Columns with Out-Of-Row Data

In a previous post, I was talking about how changing data types from the older ntext, text, and image data types to the current nvarchar(max), varchar(max), and varbinary(max) data types doesn’t achieve the same outcome as having defined the tables that way in the first place, unless you subsequently rebuild the tables.

I also had a question about how you can find out which columns still have pointers to out of row data. Unfortunately, finding that out doesn’t seem so easy and it would vary row by row in the table.

Table Rebuild Avoids Excessive Lookups After Data Type Change

I’ve run into a situation at a number of sites where the following occurs

  • An excessive number of logical page reads during query execution
  • Changes have occurred from ntext, text, or image data types have been replaced by nvarchar(max), varchar(max), or varbinary(max) data types, as part of a clean-up of deprecated data types.
  • Rebuilding the table greatly reduces the number of page reads and the customer is puzzled about why.

One of the causes for this situation is related to how the data in these columns is stored. The ntext, text, and image data types defaulted to having their data stored out of row. The row contained a pointer to where the data was located. By comparison, the nvarchar(max), varchar(max), and varbinary(max) data types default to storing data in-row where possible.

Any Australian up for doing a short MVA course?

OK, been doing a bunch of MVA courses as part of the local Microsoft AU dev div heroes campaign. I need to find 5 Australian citizens who have done at least one of the courses below, and get their email addresses.

You don’t have to do the whole of any badge. For example, you could do SQL Server 1, SQL Server 2, or SQL Server 3.

Anyone up for it? Or do all of the ones for a badge for a figurine. They are cute. There are some t-shirts on offer too.

Big Changes for Visual Studio and .NET–Where is the Ecosystem for SQL Server?

Lots of big changes for Visual Studio and .NET were announced today.

The biggest items are:

  • .NET becoming open source
  • Microsoft work to help move .NET onto Linux and Mac
  • Visual Studio 2013 Community Edition
  • Visual Studio 2015 Preview available
  • Lots of integration for Xamarin developers including Xamarin install from within Visual Studio

The one that I like most here is the Visual Studio 2013 Community Edition. We’ve had Visual Studio Express for some time but it was very limited. In particular, it blocked any attempt to extend it with plug-ins. Plug-ins are where the real creativity with the product can appear. The new community edition is full-featured and free for all except enterprise application development.
