Improving Your T-SQL Arsenal - slides
I've given this presentation a couple of times at user-groups now - last week in Adelaide, and this week in Melbourne. I posted the scripts to my blog recently, making them available to people who heard this talk at TechEd Australia at the start of the month, so now I've got around to uploading the slide deck as well.
I actually plan to blog about many of the tips too, so watch for that over the next month or so. I'll try to do at least one a week for a while, if not more. Obviously some will become longer articles, while some will be quite short. Much of the material gets covered my Advanced T-SQL Querying and Reporting course too - so feel free to check that out some time if you can.
