Many times we have to create Stored Procedures (SPs) for INSERT, UPDATE and DELETE for all database tables in any given project. These SPs does not have any business logic but just a facilitator for said operation. While preparing for my next training session on Advance T-SQL, I come across a good article on MSDN (http://msdn.microsoft.com/en-us/magazine/cc188749.aspx). This talks about, design-time automation which makes coding faster and ensures that all the procedures generated use the same naming conventions and structure.
Script to automate Insert, update and delete:
