The Bit Bucket

I’ve liked the Telerik tools for a long time. I see many of my clients using either their controls for Webforms, and many using KendoUI for newer MVC development. I suppose it’s a challenge for such vendors to work out how to best market their products, but also a challenge to show developers how to best use them.

With KendoUI, I particularly liked the Kendo Dojo idea, where you could just interactively learn to use the framework directly from inside your own browser without having to install anything locally.

A question came up from a developer yesterday. He could see how to set a transaction isolation level but didn’t know how to determine the current transaction isolation level. That detail is available in the sys.dm_exec_sessions DMV.

Here’s an example:

And if you are running SQL Server 2012, you could always use CHOOSE instead:

I spend a lot of time working with software houses, helping them to make their applications work well with SQL Server. One thing that I’ve heard loud and clear over the years is that most software houses won’t write a single line of code that will only run on the enterprise edition of SQL Server, because they are not prepared to limit their potential pool of customers to those running enterprise edition.

We’ve been so excited having local data centres for Microsoft Azure.

The one disappointment has been that Office 365/Power BI has still been based out of Singapore data centres. That has an effect on people that worry about data sovereignty and it also means that we’ve had higher latency on the connections.

But no more! I was really pleased to read an article in the newspaper yesterday that mentioned that Microsoft is moving Office 365 to the Australian data centres. The article claims this is happening in April next year. I can only hope it’s true as this will be a really good outcome thanks Microsoft!

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.

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.

Looking forward to seeing the Perth locals at the SQL Server user group this Thursday night at 5PM.

The topic that the group has chosen is an Introduction to SQL Server High Availability Options.

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.

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.

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.

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.
