How do I get the difference between two datetimes in MYSQL? -

How do I get the difference between two datetimes in MYSQL? -

मैं यह कोशिश कर रहा हूँ

  SELECT DATEDIFF (दूसरा, लॉग। Start_time, लॉग करें End_time) लॉग से सेकंड के रूप में जहां log.log_id = "कुछ पागल UUID";    लेकिन मुझे एक त्रुटि मिलती है क्योंकि  DATEDIFF ()  सेकंड की तरह कोई formatter expr स्वीकार नहीं करता है  
 तो मैंने कोशिश की,  
  SELECT second (DATEDIFF (दूसरा, लॉग। प्रारंभ_टाइम, लॉग.एंड_टाइम)) लॉग से सेकंड के लिए जहां log.log_id = "कुछ पागल यूयूआईडी ";    लेकिन यह फ़ॉर्मेटिंग के लिए काम नहीं करता है।   
 
  मुझे लगता है कि आप  DATEDIFF () :  
  सेलेक्ट टाइमस्टैम्पपीडीएफएफ (सेकंड, लॉग। स्टार्ट_टाइम, लॉग.एंड_टाइम) के बजाय सेकंड से लॉग इन करने के लिए प्रयोग के लिए लॉग इन करें जहां log.log_id = "कुछ पागल यूयूआईडी";

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?   Something like this will appear in the proxy code.    #! / Bin / bash if [[`git log_count`] ==" 0 "]]; Then there is no commodity for this repo. # What goods ... and echo are "one or more committed!" # What are the other things?    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...
