  - by Allen G

  About a month ago I saw a portfolio website in Flash that featured a stack of cards, and each time you clicked on it, they sort of blew all over the place, thus exposing the backs as videos and pictures.

• SQL Server: Are temp tables or unions better?

  - by Jonathan Allen

  Generally speaking, for combining a lot of data is it better to use a temp table/temp variable as a staging area or should I just stick to "UNION ALL"?
