Performance consideration when using a Table Variable

This is nothing new to me (I come across this autumn 2007) and probably not to you either but I forgot about it and yesterday it came alive again. I often choose a table variable for performance reasons (if data is less than 1 page anyway) due to the benefits of no logging etc etc. But yesterday I wrote a query for Phil Factor's "Subscription List" competition where I had choosen a table variable for the same reasons as before. It took a while to realize why (in this case) the solution with a temporary table was 30% faster than the solution...

New baby DBA

Today our son was born. A healthy baby of 4.4 kg (9.8 lbs) and 53 cm (20.9 inches). Both mother and son are well, and spend the night at the safety on the hospital. Water broke 2:45 am this morning and we were admitted to the ward at 4:21. Our son was born without complications at 5:06 am. Big sisters Isabelle (23 months) and Filippa (5.5 yr) are anxiously waiting for mother and new baby to get home. //Peter
