Thank you everyone who participated in T-SQL Tuesday #026! I really enjoyed hosting and reading all of the contributions. Thanks also to Adam Machanic (blog | @AdamMachanic) for starting this monthly event and for allowing me to run this show this time around.

We had 14 posts, covering about 10 different topics depending on how you count. Here’s a brief summary of them all, in the order received.

1. The first post was from Rob Farley (blog | @rob_farley), a T-SQL Tuesday regular and one of my favorite SQL bloggers. He writes about a limitation of using APPLY when dealing with working calculations which he had written about in an earlier post.

3. Steve Wales (blog | @walessj) tells a tale of T-SQL Tuesday, managing to incorporate references to all the past 25 events – very creative! He also let us in on his 2012 resolutions, which match up with mine in a lot of ways (except for that one with the “O” word )

11. Colleen Morrow (blog | @ClevelandDBA) shares some of her new year’s resolutions with us as well as her strategy for keeping up with them. I really like her idea of breaking them down into monthly chunks so they don’t seem so daunting.
