If I'm rebuilding indexes weekly, how useful is the reorganize index and rebuild statistics plan?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The Help in Microsoft SQL Management Studio recommends reorganizing indexes that have fragmentation levels between 5% and 30% and rebuilding index that have fragmentation levels greater than 30%

Rebuild - data is offline, no user access.
Reorg - data is online, but not as efficient as rebuild.

Statistics - help the Engine "guess" where to find the data.

Maybe I can narrow the question: I have hundreds of servers, so I won't monitor each one for "reorganizing indexes that have fragmentation levels between 5% and 30% and rebuilding index that have fragmentation levels greater than 30%."

I need a practical maintenance plan. I had read somewhere that if I rebuild indexes, reorganizing may not be necessary.

Will reorganizing indexes do something that a rebuild index won't do? Please don't answer the reorg does it on the leaf level, etc...I want to know if there is any benefit to doing all three jobs in a maintenance plan in one night.

no, if you "REBUILD" then you dont REORG.
Scott PletcherSenior DBACommented:
You will significantly hurt performance by recomputing statistics after a rebuild.

So you definitely don't want to do both for the same table(s).
