How to get an age from a D.O.B field in MySQL?

Question

I need to calculate the age of a \"customer\" from their date of birth.

I have tried to use the following:

DATEDIFF(year, customer.dob, \"2010

Answer 1

This is the simplest I could come up with so far:

SELECT FLOOR(ABS(DATEDIFF(d, CURRENT_TIMESTAMP, dob))/365.25) AS age

First we get the date difference in days, then convert it to years, then FLOOR truncates to the integer part of the number.
