问题
In our application we are running query 'update statistics with sample 30 percent'.
Our system design is such that we have to use update statistics query once a day to improve query performance.
We are setting autocommit as false, running 'update statistics' and then some queries which are failing causing a connection rollback.
In this case does 'update statistics' query rollback as well? Should I again run update statistics command the second time? Does 'update statistics' auto commit, or should I commit after 'update statistics' and then execute the remaining queries?
Thanks.

Update statistics will rollback back with the rest of the transaction.
