Nice job! As you might expect, you can use
BETWEEN with date and time data:
As you know from previous exercises, the zeros are added automatically. This is very convenient, but you need to watch out when retrieving rows for an entire month, year, etc. If you want all aircraft launched in November 2015, you must use the condition just as we've shown it to you:
BETWEEN '2015-11-01' AND '2015-12-01'.
The second date is 1 December because the database will add the missing zeroes:
'2015-12-01 00:00:00'. This is the exact point in time when December starts. If you wrote the second date as the last day of November (2015-11-30), you would skip all the aircraft that were launched on November 30, 2015. Keep that in mind.
