RE: dbms_utility and dbms_stat difference

Hi Cherie,

A small correction, ANALYZE also generates statisics at partition level and when an "analyze table <name> compute statistics" is done it generates statistics for the partitions. Analyze can also be run at the partition level as "analyze table <name> part (<pname>) compute statistics" and this will generate statistics only for that paritition.
Its very useful as analyze can be run for the partitions of a table in parallel and so its a blessing when running analyze on huge partitioned tables.

One of the big differences between analyze and dbms_stats is that analye cannot be run in parallel on a non partitioned table and definitely runs better in my opinion in general.

Hope this helps.
