Speaker of the Month, December 2013

Professional Development
This will be my fifth speaker of the month post. Do a search to see the others. I try to find speakers that people may not have heard of who are out there, working hard, doing a good job. But, sometimes, I'm going to see a presentation by someone who is a community speaker, and... well, it just might stand out so much that I don't have a choice but to award them (remember, my contest, my rules, and the rules are utterly arbitrary). The speaker of the month is Ami Levin (b|t). The session I attended at SQL Saturday Dallas was called Physical Join Operators. It was all about hash match, loop and merge joins. Stop yawning. I'm into that sort of thing. What I expected was, hopefully, an…

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…

Query Tuning in Dallas

SQL Server, T-SQL
Let's have some fun. This Friday, November 1, 2013, I'm putting on an all day seminar on query tuning. It's set up as a pre-conference event for SQL Saturday 255 in Dallas. It's a 200 level course on understanding how the query optimizer works, the importance of statistics, constraints and indexes, how to read execution plans, and how to take all that knowledge and go to work on tuning your queries. Here's the fun. Sign up for the seminar, and bring a nasty query you've been trying to tune or a query you don't understand or an execution plan that's making you crazy. Depending on the time available near the end of the day, we'll walk through a few of them. I've slightly restructured the seminar so I have some…

SQL in the City, US Tour 2013, Recap

Professional Development, Redgate Software
Red Gate visited three cities this year with our SQL in the City event; Pasadena, Atlanta and Charlotte. I just wanted to give you a quick assessment of how the events went from my point of view. Overall, each and every one of these events was awesome. I can safely say that because each and every one of these events provided something special, the opportunity to network with our peers and with the developers and project managers at Red Gate (who are also our peers, but not usually available to us). I both took part in the networking and stood back and watched it happen. I love seeing a bunch of data pro's sitting (or standing) in a circle exchanging war stories, ideas, questions, thoughts or suggestions. It means you…

PASS Summit 2013: Women In Technology Luncheon

PASS
This year I was invited to attend the Women In Technology luncheon as a blogger. So I'll be live-blogging it through it in the same way as I did the keynote. The WIT lunches are a fascinating, and let's face it, unique PASS-style event, that have been taking place for years at the PASS Summit. It's about growth and empowerment for women within technology. But, it's not some crazy man-bashing event. It's just another, special, way to network (that thing that PASS does so well). Panelists are Cindy Gross, Gail Shaw, Kevin Kline, Rob Farley and Erin Stellato. Mickey Steuwe is acting as moderator. The theme is Beyond Stereotypes: Equality, Gender Neutrality, and Valuing Diversity is the theme. The first question: "Do you have to make an effort to fit…

PASS Summit 2013 Day 2 Key Note

PASS
KILT DAY! Today we have to eat our vegetables and then get lots and lots of sweet desert. Or. Today we hear about PASS Finances as a part of the official annual meeting and then we get to hear Dr. David Dewitt speak (completely and utterly getting our nerd on and squeeing like teenage girls at a Bieber concert). I will be live-blogging this event, so watch this space. 8:20: Douglas McDowell kicks off the key note today.  the vast majority of the money that runs PASS comes from the Summit. That's right, by attending the Summit you're also supporting the organization. The Business Analytics Conference, which kicked off this year also provides quite a bit more money to the organization. 8:25: PASS has changed its budgeting process. At this…
