Introduction
In this article I plan to demonstrate how to insert and read data from a SQL Server or MSDE database. This code should work on both SQL Server , I am using 2000, and MSDE. I am using Visual Studio 2002, but this should work with Visual Studio 2003, Web Matrix, and the command line SDK. This code should work with both C# applications and C# web applications and webservices. This code does not compile on the FreeBSD with Rotor [^].
Background
Part of my current project required me too store and retrieve information from a database. I decided to use C# as my target language since I am currently reading Inside C# Second Edition [^] by Tom Archer [^], which by the way is a must have book. However I could not find any examples that were clear and just generic accesing SQL Server with C#.
Using the code
I did not include a sample application because the code provide within the article can really be dropped in and should work with no problem. Also through out the article I will refer to SQL Server, MSDE is a free version of SQL Server that does not have some of the GUI tools and has a few other limits such as database size. This code will work on both without problem.
Making the Love Connection
There is no real voodoo magic to creating a connection to a SQL Server assuming it is properly setup, which I am not going to go into in this article, in fact .NET has made working with SQL quite easy. First step is add the SQL Client namespace:
Collapse | Copy Code using System.Data.SqlClient;
Then we create a SqlConnection and specifying the connection string.
Collapse | Copy Code SqlConnection myConnection = new SqlConnection("user id=username;" +
