Question

What is the best way to calculate the age in years from a birth date in sqlite3?

Answer 1

I found this that maybe would help you:

select
    case
        when date(dob, '+' ||
            strftime('%Y', 'now') - strftime('%Y', dob) ||
            ' years') >= date('now')
        then strftime('%Y', 'now') - strftime('%Y', dob)
        else strftime('%Y', 'now') - strftime('%Y', dob) - 1
    end
    as age
from t;
