As well as the marvelous articles that Gail posted, Books Online has some great information in it (if you don't know what Books Online is, post back... you cannot live without it) under an index search of "index architecture [SQL Server]".


Hello Jeff,
Kindly post the link of Books Online . That would be additional for me to which Gail has posted ,


"Books Online" is the help documentation system that comes with SQL Server. You can get there by opening SSMS and then pressing the {F1} key. If you didn't install "Books Online" locally on the server, I believe it'll take you to the near equivalent on the Microsoft site auto-magically.

As a bit of a sidebar, if you Google for "what is books online sql", it'll lead you to various MS sites that either are "Books Online" for the various versions of SQL Server, or sites that you can download it from. I prefer a local copy on my desktop so that I can mark "favorites" in a dedicated fashion.

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
If you think its expensive to hire a professional to do the job, wait until you hire an amateur. -- Red Adair
