Any Example on how to configure CSV file to run SSIS packages via Batch File

Have a look at package configurations, http://msdn.microsoft.com/en-us/library/ms141132.aspx It is the recommended (and in my opinion the best) way to handle variables.

For example, I have 1 package that updates 3 different databases, the database schemas are all the same but they use different variable values (namely dates) and this is handled by a package config with a database backend. So when i need to add a new version of the database, all I need to do is add it into the configuration database and it is automatically included in the job.
