Monthly Order Count
A finance team wants a monthly cadence view of order volume. Group orders by month and show the count per month.
Show month (formatted YYYY-MM) and order_count. Order by month.
In SQLite the canonical way to extract a date part from a string-stored ISO date is strftime(format, date_column). %Y is 4-digit year, %m is 2-digit month, %d is 2-digit day. strftime('%Y-%m', order_date) gives you the year-month bucket every dashboard query reaches for.
