    select
        code,
        close,
        high,
        low,
        time
    from
        stock_prices as sp
    where
        stock_id = '1'
        and time between (
        select
            (cast('2022-06-25' as DATE ) - interval '7 DAYS') as start time) and (
        select
            (cast('2022-06-25' as DATE )) as endtime)
