sql - How do I add seconds to a timestamp of a start date so that I can get an estimated end date? -

मेरे पास एक टास्क ऑब्जेक्ट है start_time और अनुमानित समय सेकंड में। Start_time डेटाबेस में MYSQL DATETIME के रूप में संग्रहीत है और अनुमानित समय सेकंड के रूप में संग्रहीत है। मैं अनुमानित समाप्ति तिथि प्राप्त करने के लिए start_time में सेकंड जोड़ना चाहूंगा।

वहां बहुत कुछ है नेविल ने दिए लिंक पर थोड़ा सा का पीछा करते हुए ...

  my_date_time + INTERVAL xx SECOND    
  
 मुझे लगता है यह DATE_ADD () का उपयोग करने के लिए अधिक  सही  है, लेकिन जहां तक मुझे पता है कि कोई प्रदर्शन अंतर नहीं है।

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...
