sql server - Combining SQL Rows -


I have got a SQL compact database in which there is a table of IP packet headers 

  Table: : PacketHeaders ID SrcAddress SrcPort DestAddress DestPort Bytes 1 10.0.25.1 255 10.0.25.50 500 64 2 10.0.25.50 500 10.0.25.1 255 80 3 10.0.25.50 500 Table Looks Like This 10.0.25.1 255 16 4 75.48.0.25 387 74.26. 9.40 198 72 5 74.26.9.40 198 75.48.0.25 387 64 6 10.0.25.1 255 10.0.25.50 500 48 I need to perform 'Conversation' running on a local network. A query to show Packets going from A -> B is part of the conversation as is the packet going from B -> A. I need to make a query to the conversation I actually have what I want, which looks something like this:  
  returns to the question: SrcAddress SrcPort DestAddress DestPort TotalBytes bytes E & gt; B bytesby-> A10.0.25.1 255 10.0.25.50 500 208 112 96 75.48.0.25 387 74.26.9.40 198 136 72 64 As you can see that I can query query (or query series) ), A-> BB-> A and byte are calculated accordingly accordingly. I'm not a SQL master in any way, but any help on this would be greatly appreciated.   
 
 
 this:  
  select T1.SrcAddress, T1. SrcPort, T1.DestAddress, T1.DestPort, T1.Bytes + COALESCE (T2.Bytes, as 0) as TotalBytes, T1.Bytes A_to_B, Kolses (T2 in bytes, a) (selected Bi_to_a SrcAddress , SrcPort, DestAddress, DestPort, SUM (bytes) aS bytes packet PacketHeaders bytes as by headers Group SRC address, Sarseeport, Destadres, Destport) aS T1 left join (Saarsiadres, Sarseeport, Destadres, DestPort, SUM (bytes) Group by State SrcAddress, SrcPort, DestAddress, DestPort) as T 2 T1.SrcAddress = T2.DestAddress and T1.SrcPort = T2.DestPort and T1.DestAddress = T2.SrcAddress and T1. DestPort = T2.SrcPort WHERE T1.SrcAddress & lt; T1.DestAddress or (T1.SrcAddress = T1.DestAddress and T1.SrcPort = T1.DestPort) or T2.DestAddress zero  
 
 The test data: 
 
  CREATE tABLE packet headers (ID INT, SrcAddress NVARCHAR (100), SrcPort INT, DestAddress NVARCHAR (100), DestPort INT, bytes INT); INSERT INTO PacketHeaders (ID, SrcAddress, SrcPort, DestAddress, DestPort, bytes) values ​​(1, 10 .0.25.1 ', 255, '10 .0.25.50', 500, 64), (2, 10 0.25 .50 ', 500, '10.0.25.1', ​​255, 80), (3, '10.55.55 ', 500, '10.0.25.1', ​​255, 16), (4, '75.48.0 .25 ', 387, '74.26.9.40', 198, 72), (5, '74.26.9.40 ', 198, '75.48.0.25', 387, 64), (6, '10 .0.25.1 ', 255, '10.20.50', 500, 48), (7, '10.0.25.2 ', 255, '10.0.25.50', 500, 48), (8, '10.0.25.52 ', 255, '10.05.55', 500, 48);  
 
 This gives the following results: 
 
  '10.0.25.1 ', 255, '10.0.25.50', 500, 208, 112 , 96'10.0.0.225.2, 255, '10.0.25.50 ', 500, 48, 48, 0 '10.0.25.52', 255, '10.0.25.50 ', 500, 48, 48 , 0 '74.26.9.40 ', 1987, '75.48.0.25', 387, 136, 64, 72  
 
 The way it works, the same one -Star is a group of conversations and bytes total number assures that every conversation will be displayed twice every time - once for every direction This result then connects with itself to get results, so that duplicate is applied by filtration that should be less than A (address, port) B. A left join is used to perform a one-way conversation.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
