Defaults for ANALYZE

Hi all,

>From my testing in 8.1.6 and 8.1.7, it appears to me that the ANALYZE
defaults to "FOR ALL COLUMNS SIZE 1". I found this by checking the DBA_TAB_HISTOGRAMS view before and after an "ANALYZE TABLE bleah COMPUTE STATISTICS". I then compared those results to a before/after using DBMS_STATS first with "METHOD_OPT => NULL", then "METHOD_OPT => 'FOR ALL COLUMNS SIZE 1'". So, can anyone tell me where the hell this is documented for the ANALYZE command? It's not in "Oracle8i SQL Reference" under ANALYZE, where one would think it should be, nor does it show up in a search on http://tahiti.oracle.com. Same for Metaclink.

I've been pulling my hair out trying to determine why I've been getting different explain plans between DBMS_STATS and ANALYZE, until I discovered this. DBA need beer. One "Three Floyd's" left in fridge. Mmmmm...

TIA,
