sql server 2005 - How do I calculate the Azimuth (angle to north) between two WGS84 coordinates in a single T-SQL query? -

-

, but I can not translate it into a single query T-SQL because my C # implementation is required (if Again ).

I also found the following C # solution, which can be translated into a query T-SQL, but it does not produce the correct result 

  Public Stabilized Double GetAzimuth ( WGSCoordC1, WGSCoordC2) {var lat1 = DeGToRad (c1.Latitude); Var lon1 = DagTorad (C 1. Loneticate); Var lat2 = Degotrod (C2lititude); Var lon2 = DegToRad (c2.Longitude); Return Redoutong (Monastery sign (lon1-lon2) * Math. Cos (Lat 2) / Matthew Sign (Math.Ekos (Math Sign. (Lat 2) * Monastery Sign (Let1) + Math. Cos (lat 1) * math. Cos (latt 2) * math. Cos (lawn 2 - lawn 1)))); }

code

Can someone correct the above code or provide an alternative solution?

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
