MYSQL通過時間進行篩選數據，每分只取最新的一條數據

SELECT id, FROM_UNIXTIME( cen_time, '%Y-%m-%d %H%i' ) minutes, max(cen_time) as date_time,`index`,symbol,cen_time FROM tp_mdapi_stock_trend where symbol='".$game['symbol']."' and date_format(from_unixtime(cen_time),'%Y-%m-%d') = date_format(date_sub(curdate(),interval 1 day),'%Y-%m-%d') GROUP BY minutes order by id

cen_time ：當前數據時間

FROM_UNIXTIME：時間轉換，上面精確到分鐘
