Allen White, who introduced me to the wonders of PowerShell at last year's PASS Summit, has published a white paper on using PowerShell within SQL Server 2008 with Microsoft. This is great news. If you're, as Brent Ozar so nicely put it, a noob like me in working with Powershell, this is going to be a great resource. Congratulations Allen, and thanks.
I try to shy away from humor in any of my posts because what I think is funny, others think is irritating or stupid (examples: I LOATHE Adam Sandler and I thought Hudson Hawk was funny. So there. I'm completely out of the main stream of America where comedy is concerned). I wanted to post something funny about getting an upgraded listing over at SQLRockStar's Blog Rankings. I've started it several times, looking to the Oscars and trying to  imitate Sally Fields or maybe that little Italian guy, toss in a Native American being really sombre & sad, a few streakers, an old guy doing push-ups (ohe-handed, even though he cheated a bit on the form, I still can't do those, even cheating)... None of it worked. I do appreciate wit, I just…
In my previous post, Spatial Data Hurts My Brain, I showed how a query used the spatial index, but hurt performance. Several people jumped in to try to help out. Thanks to Bob Beauchamin, Isaac Kunin, Gail Shaw, and Valerie Yakich (via Twitter). I've definately learned a bit more than I knew previously about spatial data and spatial indexes. I've posted about it before, but it bears repeating, if you're just starting out, I can't recommend Alistair Aitchison's book, Beginning Spatial with SQL Server 2008, enough. Here's where I'm at. I think I was confusing/confused/confounded/something about what to expect from a spatial index. I'm going to present two queries and two indexes and try to explain why each works well, or not together, mainly as a means for enabling my…
Before I describe this, let me thank Lynn Pettis over at SQL Server Central for coming up with the answer. This morning a developer walked up and asked me what would happen if he ran a query that looked like this: SELECT 1.SomeString I said that he'd get an error. No, he says, try it. So I try it and I get this: Somestring 1 Try it yourself. It works just fine. I'd never seen that before and didn't have a clue what it was. Thinking that Microsoft had supplied some new short hand to define aliases I ran this: SELECT 'dude'.dudette Which resulted in the error: Â Msg 258, Level 15, State 1, Line 1 Cannot call methods on varchar. Â Which is what I would have expected. I…
Thanks SQLBatman. It's not like I need to do work or something. Who has been a great leader in your career and what has made them a great leader? First, I need to define what I understand a leader to be and then I'll see if I have any great ones on the list. There are a lot of ways to define what a leader is. You could say simply the managers, team leads, CEO's and CIO's that you've worked for or with are leaders. But I don't see that. I think of a leader and I see Henry V and the St. Crispin's day speech, "...And gentlemen in England now-a-bed shall think themselves accurs'd they were not here, and hold their manhoods cheap whiles any speaks that fought with…
My first book is finally in print. OK. I know. It sounds funny. But my first book was printed in only a limited print run from Red Gate, most of which they gave away at Tech Ed last year. Then they offered it for free in an electronic form. Very few people got a printed copy. Well, if you were waiting around for the dead tree version, it's here! Thanks again to Tony Davis & Brad McGehee for all the work they did. It just wouldn't have been possible without them.
Jamie Laflen and Barclay Hill have published an article in MSDN Magazine outlining the new features in in VSTS:DB GDR. The description of the intent and use of the server project is extremely enlightening. I wasn't aware of the master.dbschema files available for use within a project. Luckily I haven't needed them yet. Another thing I wasn't aware of, if you use the refactoring tools, say rename a table, not only does it save you a lot of typing, but the project will remember that the table was renamed and instead of dropping and recreating it in the next deployment, it will issue SP_RENAME. I'm spreading that word to my team right now. Another good point is that you can make a configuration to work only on your local machine…
Greg Larson posted a really nice query to find worst performing stored procedures in your system. He put in all kinds of attributes to make it customizable, changing the definition of "worst" to different measures,etc. Great query in general. In it he linked to sys.dm_exec_plan_attributes and got the db_id attribute. Duh! So instead of spelunking through the XML to retrieve the database name, I can pull the db_id and use the DB_NAME function. Cleans things up considerably. Thanks Greg. Here's the cleaned up code: WITH XMLNAMESPACES ('http://schemas.microsoft.com/sqlserver/2004/07/showplan' AS sp) SELECT DB_NAME(CAST(pa.value AS INT)) ,s.sql_handle ,s.total_elapsed_time ,s.last_execution_time ,s.execution_count ,s.total_logical_writes ,s.total_logical_reads ,s.min_elapsed_time ,s.max_elapsed_time --,s.query_hash ,p.query_plan ,p.query_plan.value(N'(sp:ShowPlanXML/sp:BatchSequence/sp:Batch/sp:Statements/sp:StmtSimple/sp:QueryPlan/sp:MissingIndexes/sp:MissingIndexGroup/sp:MissingIndex/@Table)[1]', 'NVARCHAR(256)') AS TableName ,p.query_plan.value(N'(/sp:ShowPlanXML/sp:BatchSequence/sp:Batch/sp:Statements/sp:StmtSimple/sp:QueryPlan/sp:MissingIndexes/sp:MissingIndexGroup/sp:MissingIndex/@Schema)[1]', 'NVARCHAR(256)') AS SchemaName ,p.query_plan.value(N'(/sp:ShowPlanXML/sp:BatchSequence/sp:Batch/sp:Statements/sp:StmtSimple/sp:QueryPlan/sp:MissingIndexes/sp:MissingIndexGroup/@Impact)[1]', 'DECIMAL(6,4)') AS ProjectedImpact ,ColumnGroup.value('./@Usage', 'NVARCHAR(256)') AS ColumnGroupUsage ,ColumnGroupColumn.value('./@Name', 'NVARCHAR(256)') AS ColumnName FROM (SELECT TOP 20 s.sql_handle ,s.plan_handle ,s.total_elapsed_time…
Anyone reading this who attended the New England Data Camp and filled out an eval, for any of the sessions, thanks. For those 63 evals between the two sessions that I received, thanks. Here are the aggregates on my sessions: Using Visual Studio Team System Database Edition: Average of Knowledge 8.344827586 Average of Presentation 8.482758621 Average of Preparation 8.103448276 Average of Interesting 8.172413793 Average of Overall 8.275862069 Number of Submissions 29 Understanding Execution Plans Average of Knowledge 8.647058824 Average of Presentation 8.617647059 Average of Preparation 8.705882353 Average of Interesting 8.529411765 Average of Overall 8.625 Number of Submissions 34 These are all on a scale of 1-9. I'm really quite happy with the results. Here are the average results for all the speakers and all the sessions at the Data Camp:…
I believe that the very first New England Data Camp was a success. We had about 185 attendees. There 18 sessions from 16 speakers. Both the sessions I gave and the one I sat in on were full. Credit goes to to Adam Machanic who did 90% of the work pulling this together. Amazing job Adam. My personal thanks to our sponsors. Â First, Microsoft, who provided us with a magnificent facility, nice swag, a full AV suite, coffee and donuts and in the morning, and a lot of help. It wouldn't have come out as well as it did without you guys. Next, the Professional Association of SQL Server Users (PASS), who supplied us with money, without which we could not have eaten lunch, a few posters to decorate the…
