Every once in a while, I get a request to create a report of all the SQL Agent jobs and their schedules for a particular SQL Instance. The following script was created by combining features from a handful of other similar types of scripts found on the internet which will query this information from the [msdb] database. In this script, I’ve added a feature to calculate an average run-time for each job based on any related job history information found. The script also does a nice job of showing how to convert the [msdb] integer-type date format: YYYYMMDD to a more readable format. I find this script particularly useful to use as a view in an administration type of database.
