mysql 獲取規(guī)定時間段內(nèi)的統(tǒng)計數(shù)據(jù)
按年統(tǒng)計
SELECT count(*), DATE_FORMAT(order_info.create_time, '%Y-%m-%d') AS count_by_date FROM order_info WHERE DATE_FORMAT(order_info.create_time, '%Y') = '2017' GROUP BY count_by_date ORDER BY NULL
按月統(tǒng)計
SELECT count(*), DATE_FORMAT(order_info.create_time, '%Y-%m-%d') AS count_by_date FROM order_info WHERE DATE_FORMAT(order_info.create_time, '%Y-%m') = '2017-04' GROUP BY count_by_date ORDER BY NULL
具體變換可以自己根據(jù)需求變更
