I asked a two-part question on Twitter: if you could only remove one feature from SQL, why would it be cursors?

New Music Friday: Killa DBA’s New Release Just Dropped

October 23, 2020

Familiar readers will know that I don’t actually do New Music Friday here very often. Okay, ever. I don’t do it ever. Because frankly, nobody writes music about us. Nobody except Homer McEwen, aka Killa DBA (YouTube – @KillaDBA). You may remember him from The SQL Server 2017 Song, and if not, you should go…

Poor Man’s Resource Governor: Database-Scoped Configurations

October 6, 2020

Bad Idea Jeans

Let’s say you had report queries that were going wildly parallel, and you wanted to put a stop to it, but you couldn’t afford SQL Server Enterprise Edition. You could do is create databases with different MAXDOP settings: CREATE DATABASE [MAXDOP4] GO USE [MAXDOP4] GO ALTER DATABASE SCOPED CONFIGURATION SET MAXDOP = 4; GO CREATE…

Bad Idea Jeans: Building Big Query Plans

June 23, 2020

Bad Idea Jeans

When you build a monitoring tool that sends advice via email, you discover two things: Some people have really, really big execution plans Email servers have reasonable limits on file attachment sizes Add those two things together, and Richie found himself working on a new feature for SQL ConstantCare® that would automatically break up advice…

What Does This Button Do? Wrong Answers Only.

March 31, 2020

One of my favorite memes is Wrong Answers Only, where you show something and people have to answer incorrectly, like this and this and this. So now it’s your turn: you’re in SSMS, you right-click on a database, and go into Tasks: What does that bottom right task do? Wrong answers only.

So, uh, you can, like, draw me in SSMS.

November 16, 2019

Adrian Sullivan and Michael J. Swart have way too much time on their hands, because Adrian just posted this T-SQL gist, which draws … me: It uses the spatial results feature in SSMS. My mind is blown. I’m totally going to use that in a demo. Thanks, Adrian! I’m already envisioning all kinds of crazy…

Brace Yourself for These 9 Database Horror Stories

June 24, 2019

Last week, I asked for your worst database horror stories. Hoowee, did you deliver. Make yourself a nice cup of cocoa, gather around the campfire, and listen up for these terrible tales. Illustrations courtesy of Swear Trek (not safe for work.) The mistake we’ve all made Russ did an update without a where clause, but…

Contest: What’s Your Worst Database Horror Story?

June 17, 2019

At SQL Intersection in Orlando last week, a few of us were sitting around a table talking shop. One thing led to another, and as so often happens at conferences, we started talking about our worst scars from database misfortunes. That got me thinking – I could kinda bring that fun experience to y’all here…

Pop Quiz: SQL 2000 Bug or SQL 2017 Bug?

May 1, 2019

2002: Me and Bailey, mom’s Great Dane When I was thinking about this site’s 17th birthday, I started wondering: back in 2002, what bug might I have been working with in SQL Server? I started reading back to the list of bugs fixed in SQL Server 2000 Service Pack 1, and it hit me…these bugs…

One Hundred Percent CPU

September 18, 2018

Raise Your Hand If You’ve ever wanted to play a prank on your co-workers, but just didn’t have a any ideas that didn’t involve exploding Hot Pockets. Now you have something even less safe than molten cheese squirts! A stored procedure that pushes CPUs to 100%. All of’em. Transact-SQL CREATE OR ALTER PROCEDURE dbo._keep_it_100 AS…

300 Blogs And Running

June 21, 2018

Why Bother Blogging? I blog primarily because there’s a Certain Kind of Person that irks me to no end. The kind of person who: Withholds information (you wouldn’t understand anyway) Mocks people for not knowing what they know (oh, you silly things) Uses the people they mock to validate their necessity (you’d be lost without…

Stupid T-SQL Tricks

Bad Idea Jeans, T-SQL

Presented without comment: Transact-SQL CREATE TABLE dbo.[FROM] ([SELECT] INT, [WHERE] INT, [LIKE] INT); GO SELECT [SELECT] FROM [FROM] WHERE [WHERE] LIKE [LIKE]; GO 1234 CREATE TABLE dbo.[FROM] ([SELECT] INT, [WHERE] INT, [LIKE] INT);GOSELECT [SELECT] FROM [FROM] WHERE [WHERE] LIKE [LIKE];GO Next up, can you break up a query with spaces? Yep: Transact-SQL SELECT * FROM…

Stuff People Tell Me Is The Default

May 18, 2018

Playing The Odds Assuming that life carries on as usual for a couple more weeks, I’ll have been a consultant here for three years. In that time, I’ve had some really interesting conversations with people, mostly about why things are the way they are on their servers. My favorite response is “isn’t that the default?”,…

Thanks for joining me today – I know you reporters are all really busy, and I appreciate you taking the time to attend this press conference.

How To Break SQL Server’s XML Data Collection

April 7, 2018

No Comments

Oh, XML When we first met, it was about 2011. I had to load files full of you into a table. It wasn’t so bad. Seriously. You were well-formed, and didn’t change from file to file. Even using SQL Server 2005, I could take you. Later on, we got really close when I awkwardly started…

Let’s Give The Optimizer A Name

February 21, 2018

Humor, SQL Server

Clunky As my favorite monkey likes to say, the hardest things do with computers are: 1. Naming things 4. Asynchronous processing 2. Cache invalidation 5. Off by one errors Things are tough for Microsoft, too. Take “the optimizer” for instance. It’s based on something called the Cascades Framework. No one wants to say “Cascades Framework”,…

How to Throttle Logins to SQL Server

February 20, 2018

Bad Idea Jeans

So, uh, you can use WAITFOR in a logon trigger: Transact-SQL CREATE OR ALTER TRIGGER SorryNorm ON ALL SERVER FOR LOGON AS BEGIN IF ORIGINAL_LOGIN()= 'NormTheNewGuy' WAITFOR DELAY '00:00:15'; END; GO 123456 CREATE OR ALTER TRIGGER SorryNorm ON ALL SERVER FOR LOGON ASBEGINIF ORIGINAL_LOGIN()= 'NormTheNewGuy' WAITFOR DELAY '00:00:15';END;GO You probably don’t want it to be TOO…
