RE: drop a histogram on a single column

I believe this will work:

exec dbms_stats.set_column_stats(user,'table_name',colname=>'column_name',distcnt=><num_distinct>);

Just find out what the current num_distinct is, then run the above procedure to manually set it to the same value and I believe this will have the side-effect of removing the histogram from that column while keeping all other stats intact.

I'm not sure if this is a documented side-effect so you might want to test first and use at your own risk.

Regards,
Brandon
