I have a water pump that the run state is stored in a mssql database every 10 seconds along with the time of day. The pump cycles often through out the day. How do I query for the total time the pump was on during the day?

Take the result, and multiply by 10 to get time on in seconds?
As mentioned in the comments, if you also select the date and
GROUP BYdate you can get counts per day.
