I have a MySQL table called Hotel. in that i have the following fields ID,hotelName,Address,YearOfEstablishment.
The YearOfEstablishment is type Date and it’ll store a date as 2010-12-26. What i need to do is to find the difference between the dates, and the SQL for that is as follows;
SELECT DATEDIFF('2011-08-08','2010-07-26');
The answer for the above query will be given in days, like for example the difference between the 2 dates might be 120 days, I need to show this in Years. Like to divide the value 120 by 365 and give the number of years. How do i write the SQL statement for this?
2.) Now i need to write another SQL, that would show all the Hotel table columns and the Year difference values (that is explained above). How do i write the SQL for this?
(I am using MySQL)
SELECT DATEDIFF('2011-08-08','2010-07-26') / 365;SELECT ID,hotelName,Address,YearOfEstablishment, DATEDIFF(YearOfEstablishment,'2010-07-26') / 365 AS years FROM Hotel;However, be sure to know that an average year has 365.2425 days.
And if your reference datetime is now, simply use
NOW():SELECT DATEDIFF('2011-08-08',NOW()) / 365;.
