Windows Azure Views

Azure
It's kind of fun to see Azure development artifacts on display. I've posted about them before, a couple of times. I'm starting to finally get systematized about the whole thing, just so I can see stuff as it changes rather than discover them by accident or get told about them by someone else. Here's a little query I'm running to see when system views were last modified: SELECT av.name, av.create_date, av.modify_date FROM sys.all_views AS av ORDER BY av.modify_date DESC; The most recent stack of changes are here: I'll keep an eye on them to see what I can spot about interesting new functionality. I also compared the listing of all views in Azure to those on a SQL Server 2012 instance and came up with a list of differences. These…

Cargo Cult Data Professionals

Professional Development
Ever since David Moutray introduced me to the concept of cargo cult programming, it's been running round and round in my head. I'm actually coming to believe that this is a major issue in all walks of life. True or not, we're absolutely seeing it in the data professionals space. Don't believe me? OK. A few questions. Do you work for one of the organizations that absolutely requires NOLOCK on all queries (even INSERT/DELETE/UPDATE)? Why? Because it runs faster? Why don't you just use READ_UNCOMMITTED for your isolation level? What's that? Never heard of isolation levels? I'll bet you also don't know what is meant by "dirty reads" then either. READ_COMMITTED_SNAPSHOT anyone? In short, you're guilty of being in a cargo cult. You've got this form in your head of…

For the Aspiring DBA

Professional Development
Getting started as a data professional is an incredibly daunting task. If you’re not concerned that you’re going to mess stuff up and cause a system to crash and burn, maybe you’re in the wrong job. The amount of information you have to learn is insanely huge, coupled with the fact that you are straddling application development, system administration and business needs, multiplied by the factor that all the apps, all the code and the very server structure on which you’re building everything is constantly changing. Concerned now? Good. Stay that way. The one piece of advice I want to offer you is that very state of concern. You are in a wonderful and horrifying position. If you’re working in the database administration space, you’re tasked with protecting the data…

More Azure Goodies

Azure
Microsoft keeps sneaking little things under the door for Windows Azure SQL Database. This time it's a couple of new views, a system view and a Dynamic Management View (DMV); sys.resource_stats and sys.dm_operation_stats. But, I also learned another fun fact, not all this stuff rolls out at the same speed. For example, if I run sys.resource_stats on a database on a server located in the North Central US data center, the output looks like this: But, if I run the same query against the same view with a database in a data center in East Asia (I experiment with where I put things), it looks like this (click on it to expand it, probably want to do that into a second tab or window so you can refer to it…

Speaker of the Month, November 2013

Professional Development
Yeah, I'm a couple of days late. Tough. My blog. My rules. Speaking of rules. Speaker of the Month is chosen by me based on my whims, interests and the direction of the wind on every other Tuesday at 3PM. No whining. I saw a ton of excellent sessions during the month of October. I was at SQL in the City, SQL Saturday Charleston, and the PASS Summit, so I had an embarrassment of riches to choose from. One session stood out. It's on a topic that, frankly, I find incredibly dull. But not this presentation. Without further ado, for November I'm picking Chris Bell (b|t) and his presentation, Indexing Encrypted Data (oh stop yawning, this is good). Chris went to town on the slides. He's clearly very carefully built…
