tsql - SQL If "something" select count -


मेरा एक कस्टम व्यू से आ रहा आउटपुट इस प्रकार है ... 

  Col1 Col2 Col3 Col4 xxxx केक 1 1 * केक xxxx 2 * 1 xxxx केक 2 0 * xxxx केक 0 0 * केक xxxx 2 * 0 केक xxxx 2 * 0

और मैं क्या चाहूंगा राशि के लिए है ... 

  हर पंक्ति के लिए, यदि शब्द केक को 1 में मिलते हैं, तो कॉल 3 का मान जोड़ना और फिर योग करने के लिए Col4 का मान जोड़ना  < / पूर्व> 
 उपरोक्त दृश्य से SUM का परिणामस्वरूप, 1 + 2 + 0 + 0 + 2 + 2 = 7 
 
 पहले से धन्यवाद! 
 
 ps तारों को सिर्फ दिखाने के लिए जोड़ा जाता है, जो राशि को योग में जोड़ा जाना चाहिए। 
 

  SUM का चयन करें (प्रकरण जब Col1 = 'केक' तब Col3 होता है जब Col2 = 'केक', फिर से 4 दूसरा 0 ईडी)

'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...
