經常使用sql彙總

-- 常見的sql json 替換查詢 表頭金額彙總的數據升級 --
update t_template_bill header INNER JOIN
(select sum(SUBSTRING_INDEX(REPLACE(json_values,CONCAT(SUBSTRING_INDEX(json_values,'"ud_jine":',1),'"ud_jine":"'),''),'"',1)) as sum_amount,parentid FROM t_template_bill_entry GROUP BY parentid) entry
on header.id = entry.parentid set header.bill_amount_basic = entry.sum_amount;
