It is T-SQL Tuesday time again. To be exact, this month's T-SQL Tuesday is the 37th and with that the first in the 4th year if the blog party. Yes – that is right. The first T-SQL Tuesday round lead by Adam Machanic (B|T) himself happened exactly three years ago in December 2009.
So before I invite you to join the newest party I would like to wish all of you a Happy T-SQL Tuesday Anniversary.
As many of you know already, I decided to declare December 2012 as the month of the JOIN by writing the A Join A Day blog series. So, it should be quite obvious what this month T-SQL Tuesday is about. You guessed correctly — I would like you to join me in talking about joins. Now you might think "If Sebastian is writing 31 posts about JOINs already there is nothing left to write about." But I can assure you that there is still plenty out there. In my series I am going to cover just the basics. For example, what is a cross join or an anti-semi-join? What is the difference between a hash and a merge join? There are many things I won't be able to cover, for example how to write efficient join queries.
Your mission – should you accept – is to write about topics like the good and the bad patterns of joining you have seen out there or really anything else that comes to your mind when thinking about joins:
And if you have a topic that you always wanted to write about but that is only remotely related to joins, feel free to use it anyway and make sure to tell us why you think it is related to joins.
Hope to see you (or at least your post) next week at the party.
As you can see there are a lot of topics and ideas around joins that are just waiting to be written about. I can just see that post already forming in your head. Now you just need to start writing it down.
There are a few rules and regulations that you should follow while attending this party so that nobody feels left out or mistreated.
And while it is not part of the official rules, I would appreciate if you would reference the A Join A Day – Introduction too:

This T-SQL Tuesday invite is part of my December 2012 "A Join A Day" blog post series. You can find the table of contents with all posts published so far in the introductory post: A Join A Day – Introduction. Make sure you check out that post while you are thinking about the topic you are going to write about next week.
