Using User Defined Functions in Table Inserts and Seeding with Stored Procedures

Overview

This article (my first), demonstrates how to automatically set column values with INSERT statements. I show two methods: The first automatically generates a unique code on a Table INSERT using a User-defined Function; while the second uses a Stored Procedure to insert Rows into a table with specified or default index numbers.

Background

Do you ever need to seed index columns like task numbers or steps in a sequence? How about automatically generating a unique code for a customer? My solutions to these problems follow. These may not be the best, or most elegant ways to implement this functionality, but it is a good starter.

The first thing we have to do is open SQL Management Studio (SSMS) and create a sample database named DemoTaskList; then in a new query window, we create our first table:

MVC Architecture Model In ASP.NET

Image
When developing ASP.NET applications the need of reducing code duplication increases along with their complexity. This is because testing and performing changes become very difficult tasks when having many different sources of code with the same functionality. Model View Controller architecture (or pattern) allows us to separate different parts of our applications into tiers to fulfill this need. MVC Overview Model View Controller architecture aims to separate an application into three parts: Model:  It is the business logic of an application. From an object oriented perspective it would consist of a set of classes that implement the critical functionality of an application from a business point of view. View:  It can consist of every type of interface given to the user. In ASP.NET the view is the set of web pages presented by a web application. Controller:  This part of the architecture is the most difficult to explain, hence the most difficult to implement in ...
