RE: Table Scans

I am curious about something in your query.

> SELECT distinct(o.object_name),o.object_type,o.owner
> FROM dba_objects o,x$bh x
> WHERE x.obj=o.object_id
> AND o.object_type='TABLE'
> AND standard.bitand(x.flag,524288)>0
> AND o.owner<>'SYS';

Where did you learn of the correct pattern for the "AND standard.bitand(x.flag,524288)>0" clause?

Thanks,
Mike
