SQL Query for clearing polls

[Gtman]

After pruning all polls I still see that the polls are visible without any content on threads.

So how would I run a query that completely prunes a forum of all polls.

Go to: ACP > Tools and Maintenance > Recount and Rebuild > and run the following options;
Recount Statistics
Rebuild Forum Counters
Rebuild Thread Counters
Recount User Post Counts

No thank you.
It had nothing to do with a recount but a glitch that had empty polls (No options) on threads.

UPDATE mybb_threads SET poll = '0'

Solved it.
