mysql - Select rows with the same Item name and show lowest Price -

-

We have two tables: 

  product IDs. Items | Supplier 1 | Harry Potter | Warner 2 | Harry Potter | Warner 3 | Throne game HBO 4 | The Simpsons | Warner 5 | The Simpsons | Warner   
 and  
  value ID. Price 1 | 10.9 9 2 20.00 3. 20.00 4 10.00 5 | 12.00   
 I am trying to get the lowest price item where there are two items with the same name and supplier.  
 I can find those rows where duplicates are as follows:  
  SELECT Products.ID, Products.Item, excluding products.Supplier, Prices.price products Prices at Price Id = product. Id where the product. ID IN (Item ID from the item where Supplier = "Warner" group item has been counting (*)> 1)   
 How can I modify only this I duplicate item name ?  
 I tried to order but it throws an error for me.  
 The result should be:  
  id. Items | Supplier | Price 1 | Harry Potter | Warner | 10.9 9 4 The Simpsons | Warner | 10.00   
 Thanks,  
 Rick   
 
 
 All your implementation of tables must be improved in the first place if your product table has the ID as the primary key, then your data will be as follows (you need the primary key).  
  Product IDs. Items | Supplier 1 | Harry Potter | Warner 2 | Throne game HBO Value ID | Price 1 | 10.99 1 20.00 2. 20   
 Now use the minimum task to select minimum prices  
  SELECT Products.ID, Products.Item, Products.Supplier, MIN ( Prices.price) Prices at the left price from the products. Id = Products.ID;

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

I am trying to create Java web framework (and learning), and on the basis of 'Code Generator In the process of making the material view of the database in the process of development, I stumbled into a difficulty, which I do not know how to solve it.
