How to group headers and footers in SQL Server with GROUPING BY? -

-

I have seen similar references but still could not find the solution.

I have three pillars: class, UPC, value. Value for class: A, B, C

Value for the UPC: A001, A002, A3003, B001, B002, B C3, C001, C002, C003.

I need to use GROUPING BY because I need to show value totals.

What do I need: 

  | - Class - | --UPC-- | --Price-- | Aaic $ 1.15 aad2 $ 4.45 ax $ 1.75 a $ 7.35 bbis $ $ 2.00 b002 $ 4.00 b3 3bb $ 9.00 ccc $ $ 10.00 cad 2 $ 20.00 cad 3 $ 30.00 C $ 60.00

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
