SQL -911 is an error that comes due to the db timing out. Please wait for some and try running your Query. If this does not solve the issue. Please contact the admin of that datbase and have him look at what is hogging the data base. If it is a old session or unwanted activity it can be terminanted by the admin and you will be able to run your queries without any issues.
