Programatically Connecting to MS Exchange Using EWS

You can do a lot with your code when you write an application that communicates with your Exchange server. But getting the setup to work for you in Visual Studio isn’t always as intuitive as it should be. Here are the steps I went through getting my project in Visual Studio set up and connecting to MS Exchange.

SQL Server – Pass a List from your ASP.NET Code to a Stored Procedure using XML

Sometimes while developing a tool, a developer needs to pass a list of values with a variable size to their database. There are several ways of doing so, one of which involves passing the list in XML format.

The introduction of SQL Server 2005 offered the use of XML datatypes, which had not existed in previous versions of SQL Server. The good thing about the XML datatype is that it is not just good for storing information in XML format, but also has advantages such as being fully query-able similar to a database table.

As you look through this example, please feel free to check out other articles I have written for more SQL Tips

Here are the three main ways of passing lists of parameters to the different versions of SQL Server

A big benefit of the XML datatype is the ability to pass lists of items to stored procedures as XML format parameters. In SQL Server 2000 one would have to pass a list of parameters as a String that would then need to be parsed into its components in the Stored Procedure. This a tedious process that could easily introduce parsing errors. Subsequent versions of SQL Server have added extra ways in which to pass information lists to Stored Procedures:

  1. As a character-separated list contained in a String (VARCHAR) variable –¬†SQL Server 2000 +
  2. As an XML variable – SQL Server 2005 +
  3. As a table variable – SQL Server 2008 +

As you can see from the list above, the methods of passing lists to stored procedures have increased in number over the last few iterations of SQL Server. The catch of course is that as a developer you will need to adapt your code to whichever instance of SQL Server your project is based on.
