sql - Assign value for each row -

प्रत्येक तालिका पंक्ति के लिए t-sql अभिव्यक्ति कैसे निर्दिष्ट करें? उदाहरण के लिए:

  उपयोगकर्ता में उपयोगकर्ता का अंतिम उपयोगकर्ता {user.place = SELECT COUNT (*) AS [value] FROM [Users] AS [t0] WHERE (COALESCE ([t0]) [वोट] , @ पी 00)) & gt; @ P1; }    जहां  उपयोगकर्ता  तालिका है यह छद्म कोड है लेकिन मैं इसे  t-sql  संग्रहीत कार्यविधि में करना चाहता हूं।   
 
  तो आप सभी उपयोगकर्ता रिकॉर्ड चाहते हैं, और प्रत्येक रिकॉर्ड के साथ, एक गिनती ..  < P> आप एक subquery का उपयोग कर सकते हैं - लेकिन @ पी 0 और @ पी 1 क्या हैं? [उपयोगकर्ता] एएस [टी 0] जहां COALESCE ([टी 0]] [वोट], 0) से [यूट्यूब], [0] के रूप में [वैल्यू] का चयन करें। यूजर से यूजर यू   
 एसक्यूएल सर्वर 2005 से, आप विंडोिंग फ़ंक्शंस का उपयोग कर सकते हैं  
  SELECT u। *, प्लेस = रैंक ( ) से अधिक (यू.वॉट्स द्वारा क्रम) उपयोगकर्ता से

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -



    I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device.   Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed. Add VS2010 / Select a component in the Remove screen.      You will get your VS2010ToolsMVC2.msi VS2010 DVD under WCU \ ASPNETMVC - hopefully it will do!    






Git Bash script to check whether repo has any commits? -



    I have a script on which I need to work differently if there is one, which is one or more , Commits. What is the best way to do this?

Any ideas?      you can    git rev-parse -verify HEAD    (after :)     This is a pipeline command, and its behavior vs. "  git diff " There is very little possibility to change   I find it more pronounced  rev-parse -verify  means "is this a valid object name?"    This is your  show-ref .  You ask "Is there anything in this safe / head in the safe?"  I ask, "what current  head  exists?"   In practice, both of these are fair tests, because once you have a branch, so to achieve the  HEAD , some mock values will indicate manually lack of editing It is very diffic...
