I have tried drop stats statement in TD 14.10. It is throwing an error "query invalid". The same worked in TD 14.0.  Is there any thing changed in 14.10 regarding statistic statment ?
Ex: Drop stats on tablname column (colname);

I have a long query generated from Microstrategy with lots of joins which was running our of spool space. I checked the query and confirmed that we had stats collected on all the join columns and stats were current. Then there was one column on which I dropped stats, it had both single and multi column stats after which the query started to run fine.
