Question

I have two field in a database table departureDateTime and arrivalDateTime and the values like

departureDateTime=03/18/2012 1:05 PM 

arrivalDateTime=03/18/2012 3:15 PM

I have hundreds of records in the table.

I need to sort and display according to the duration from these two time. I know to calculate the duration from two dates

Duration=(strtotime($arrivalDateTime') - strtotime($departureDateTime))/3600

But how I write a mysql query to sort and display these 100 records from database

Does any one any idea?

Thanks

Answer 1

Change your departureDateTime to DATETIME instead of varchar or whatever you are currently using. Then you would use something like this:

SELECT other, stuff, TIMEDIFF(departureDateTime, arrivalDateTime) as theDifference FROM myTable ORDER BY theDifference ASC LIMIT 0, 100
