SQL server? 2005 or later?
you can have horizontally partitioned tables, and only rebuild index on
the partitions that have fragments. but it's not a simple change if the
database is not already setup this way
index

: We have a 800G database. The administrator set the reorganize/Rebuild index
: once a week. It takes more than 2 hours to reorganize index and over 8
: hours to rebuild index. Is there a way to shorten the time?

是的,可以写个SP CHECK FRAMENTATION所有的INDEX,然后REBUILD FRAMENTATION到一
定程度,比如40%+的。注意REBUILD要在系统IDLE的时候半夜鸡叫的时候,不要有其它
JOB或者BACKUP RUN,看你的时间那么长,你的数据可能需要ARCHIVE了
