SQL University: SQL Azure & PowerShell

Azure, PowerShell
Welcome once more to the Miskatonic branch of SQL University. I see that most off you survived out last encounter… uh, class. Most of you even appear somewhat sane… somewhat. Today we’re going to talk about PowerShell and it’s use with SQL Azure. Which sounds a something like an eldritch horror breaking in from some outer dimension… hmmm… that could explain certain things… So, back to Powershell and SQL Azure. You can’t run Powershell from SQL Azure. Thank you for attending and enjoy your trip home. Still here? I did try. Let’s clarify. You can’t run PowerShell from SQL Azure, but I didn’t say that you couldn’t use SQL Azure as a target for PowerShell. It is possible to connect to your SQL Azure databases running PowerShell from a local…

SQL Azure Diagnostic Tool

Azure
One of the CSS Engineers from Microsoft has released a diagnostic tool for SQL Azure. It's worth a look. It's just using standard DMO queries to pull back data, but they're put them together inside a nice UI to help out. If you're already a DMO super-star, this might not be useful, but if you're looking for an easy way to gather data from your SQL Azure instance, this is a good choice. Just remember, although it wasn't mentioned on the MS web site, I'm fairly certain you get charged for running these queries. It's always something to keep in mind when working with SQL Azure.

SQL Azure Deployments

Azure
You’ve set up your access to a SQL Azure site so you’re ready to go. Now how do you get your database up there? Well, TSQL works just fine, so you can script it all out to a file or set of files and apply them. Because you can connect with SSMS, you could use the GUI to build out your database. You can also use the Azure development platform and it’s web based GUI to create your database structures. Personally, the scripting method doesn’t seem too bad to me because you can get your code into source control that way. But, Microsoft has something additional in mind. It’s called Data-tier Applications or DAC for short (and yes, there are other things called DAC in SQL Server, what can I…

SQL Azure Cost

Azure
We’ve all heard the scary stories. A developer starts testing Azure and then suddenly gets a thousand dollar bill on their credit card. The whole idea behind Azure works of the premise that you are not paying for the infrastructure. Instead of buying servers and disks and racks and switches and routers, you just pay for access and storage. It’s a great model. That model is  especially applicable to small businesses that just can’t  afford the outlay, or to a larger company that wants to perform cheap experiments, or any number of other places where purchasing and maintaining hardware just doesn’t make sense. But what are the costs? That’s a little tricky to answer, truth be told. SQL Azure is charged a monthly fee based on the size and number…

SQL Azure

Azure
If you’ve talked to anyone from Microsoft recently you had to have heard the phrase “all in.” It’s been made very clear. Microsoft is all in on the cloud. What’s that mean? My understanding of it means they are really, seriously committed to building a viable and large presence there. Part of that presence is SQL Azure. Say the word “cloud” and watch DBAs flinch, wince or moan, sometimes all three at once. I have been one of them. I looked at the list of restrictions on a cloud database, snickered, and moved on. But you know what? They’re wrong and I was too. The cloud is absolutely coming. Microsoft is not alone in believing this. Look at the offerings from Google and Amazon and others. It really is becoming…

Performance Tuning: Start to Finish

PASS
The very first ever SQL Rally is taking place in a little less than four weeks in Orlando Florida. It’s going to be quite the event. There will be two full days of sessions on any number of topics. But before that all starts, there’s going to be a set of full day pre-conference seminars. These too are on a number of topics, but I’m hoping to draw your attention to just one, mine. I’ve put together a seven hour session on query performance tuning. I’ve tried to make it as complete as I possibly can. I’m going to cover the whole process from collecting data on your machines to identify where problems may be, to understanding the optimizer so you know how things work, to reading execution plans so…

SQL University: Index Usage

SQL Server, T-SQL
Greetings. Welcome once more to the Miskatonic University branch of SQL University. Does anyone know where to buy some camping equipment, cheap? I’ve been tagged to go an expedition to Antarctica and I need some cold weather gear a bit more substantial than my LL Bean boots. Evidently the last expedition found some caves in some mountains down there. Sounds like the perfect place to get away from all the crazy stuff that goes on here at Miskatonic. I mean, what could happen? Anyway, our last several talks have all been about indexes and indexing. One of the things that we haven’t talked about is how to tell if, how or when your indexes are being used. Starting with SQL Server 2005, and continuing to 2008 and R2, there has…

SQL Saturday #71 Wrap-up

PASS
It’s over. It’s finally over. This year, unlike previous years, Adam Machanic (blog|twitter) was very good about delegating the work. Which, is actually a mixed blessing. I did a lot more work this year than I have done in years past. Luckily, we had more help this year from, new MVP, Mike Walsh (blog|twitter) and Tom LaRock (blog|twitter). The team came together and pulled off the event with the help of a great set of volunteers. Of special note, Allen White’s (blog|twitter) wonderful wife, Cindi, stood at the front desk all day, and in other ways helped us organize and run the event. It would not have been the same without her. Thanks so much. We couldn’t have pulled it off without our vendors. Here is the rather substantial list.…

SQL University–Recommendations for a Clustered Index

SQL Server, T-SQL
Welcome, SQL University Students to another extension class here at Miskatonic University, home to the Fighting Cephalopods (GO PODS!). Never mind the stains on the floor, or the walls…or those really nasty ones on the ceiling. There was a… oh what did the dean call it… an incident last week when one of the students had a little accident after reading Die Vermiss Mysteriis one too many times. But we’re not here to talk about arcane tomes and unspeakable horrors today. No, today we’re here to talk about clustered indexes. SQL Server storage is really predicated around the idea of clustered indexes. Don’t believe me? Let’s list a few places that require a clustered index: Partitioning. A table in SQL Azure In order to create XML indexes What about the…
