With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

How to generate dynamic SQL queries in Visual Studio 2008 .NET

Asked by electricd7 in Programming for ASP.NET, .NET

Hello,

I am very new to ASP.NET but have been doing ASP classic for years. I am trying to setup my first simple .NET page displaying data from a SQL database. I am used to do set RS = Server.CreateObject("ADODB.Recordset") and was hoping there was something similar to it in .NET so I could just script in all my SQL calls, but thus far I haven't found it. So I have created a Repeater and bound it to a datasource which I built using the wizard. The problem is, I am not sure how to set the query parameters to dynamic values from the QueryString. Here is the code I currently have. I would like the query at the end to be the same as the 'sqlquery' variable I built at the top. Thanks!
