Agreed, re-indexing is one of several things that should be automated on your db server from the getgo.:-D

'It's something that should be scheduled and automated.'

True, if you have the window to do it - not always possible without affecting the system's usage.

Databases are not self-healing animals, they require maintenance windows, period. I usually do weekly online re-indexing between 3-5AM on a Sunday morning, after the Sunday backups have taken place. In that way, I don't affect my U.S. systems adversely, even the 24/7 databases. For overseas databases i adjust accordingly.:-D

Catch-22. Not doing it will likely affect the "system's usage", as well.

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.
Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is not.
Just because you can do something in PowerShell, doesnt mean you should. Wink
