I need to reorg/rebuild the indexes on a large table (8.7 billion rows of data), should I rebuild the clustered index first or the non-clustered indexes first, or does it not matter?

Thanks,

Doesn't matter at all (providing you aren't using SQL 2000)

Thanks Gail, that helps with the order of operations Smile

Is there some literature I can read up on that explains why it doesn't matter?

Thanks Again.

Order doesn't matter because they're independent operations, they don't interfere or interact with each other, hence it has no difference at all what order you do them

Gail answered the question that you asked.

To simplify and shorten such reindexing of this large table, have you considered either Paritioned Views or Partitioned Tables?

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
