Setting up Database Mail
The automation of database maintenance is crucial to ensuring that a database is regularly checked, maintained, and optimized.

Automation ensures that these activities do not consume too much of your time, so you can focus on more pressing issues (such as improving your golf game, perhaps).
Ideally, SQL Server can monitor itself and send alerts when it encounters a critical condition. Luckily Microsoft grants this specific wish, because SQL Server includes a powerful component that can send alerts when specific critical conditions occur. Better still, this same component also enables the scheduling of routine maintenance tasks either on a one-time basis or on a recurring basis—for example, once a month or, say, on the first Saturday of every month. SQL Server Agent is the service responsible for processing alerts and running scheduled jobs.
SQL Server Agent service is not available in SQL Server Express Edition, for which scheduling of jobs has to be done using Windows Scheduler. For more information on Windows Scheduler, search the web, using ...
