回答1:

try this

SELECT strftime('%Y', Date),SUM(replace(price, ',', '')) FROM example GROUP BY strftime('%Y', Date);

回答2:

I suggest this sintax:

SELECT strftime('%Y',Date), SUM(replace(price, ',', '')) FROM example GROUP BY strftime('%Y',Date);

Hope it helps

There is no function year() in sqlite. You must use function strftime() instead.

For example, to get year value of the field Date, you can use strftime("%Y", Date).

Therefore, you must replace year(Date) in your query by strftime("%Y", Date).
