RE: Does index need rebuilding when table is truncated

I'm not sure. My gut says yes... because there's nothing left in the table, why should there be anything "left" in the index in the way of storage... but I don't know for sure. May be a fun thing to play with. (Wow, I need to get out more)

List? Someone has to know this.
