BEGIN update jw_items AS jw set jw.chupiao_top = 0; update jw_items AS jw set jw.chupiao_top = unix_timestamp(jw.quchendate) WHERE (jw.chupiaodate = DATE_FORMAT(now(),'%Y/%c/%e')) AND ishidden <> 1; END
2、定时检测付款状态把未按设置时间段的订单重置
1
update jw_orders od,jw_config conf,jw_items jw set od.paystate = 3 WHERE (from_unixtime(od.ordertime + conf.order_keeptime*3600) <= NOW()) AND (od.ordertime > 0) AND (jw.id = od.itemsid) AND (od.paystate IN (1,2))
3、把相关字段日期字符转unix时间戳
1
unix_timestamp(xxx_field)
4、把字符串日期格式加一天并更新
1
UPDATE tables SET field = date_format(DATE_ADD(STR_TO_DATE(field,'%Y/%c/%e'),INTERVAL 1 DAY),'%Y/%c/%e') WHERE id = xxx
5、保留七天日志
1
DELETE FROM jw_tablesxxx WHERE op_time < (UNIX_TIMESTAMP(DATE_FORMAT(NOW(),'%Y-%m-%d')) - 604800)
6、 删除无关系操作日志
1
DELETE tb_a FROM jw_xxxx_logs as tb_a INNER JOIN(SELECT jw_xxxx_logs.id FROM jw_items RIGHT JOIN jw_xxxx_logs on jw_xxxs.id = jw_xxxx_logs.jwid WHERE jw_xxxs.id IS NULL) as tb_b on tb_b.id = tb_a.id
SELECT FROM_UNIXTIME(date, '%Y-%c-%d %h:%i:%s' ) as post_date , date_format(NOW(), '%Y-%c-%d %h:%i:%s' ) as post_date_gmt FROM `article` where outkey = 'Y'
