In SQL Server, there are several ways to change a server's configuration options, but they all have drawbacks. For example, you can use a GUI such as SQL Server 2005's SQL Server Management Studio (SSMS), but you can't use it to programmatically change server configuration options. Alternatively, you can use the sp_configure system stored procedure, but you can change only one configuration option each time you execute sp_configure.
Wanting to programmatically change many configuration options without having to execute sp_configure numerous times, Eli Leiba came up with a different approach: List all the configuration options to be changed in a configuration (.config) file and use a stored procedure to apply those changes.
