    Re: Sql database query

    That code doesn't seem to make sense. I'm not sure exactly how T-SQL would treat this line:
    Code:
    SET @Rt = Total = @Rt + Area1 + Area2
    but can you explain what it's actually trying to do?

    Reagrdless, in VB.NET you interact with SQL Server using the SqlClient ADO.NET provider. Follow the CodeBank link in my signature and check out my thread on Retrieving & Saving Data. One of the examples calls SqlCommand.ExecuteNonQuery. That's the one you want to follow. You just need to adjust the SQL code and the parameters.
