MYSQL替换时间替换时间(年月日年月日)字段时分秒不变实例解析字段时分秒不变实例解析

主要介绍了MYSQL替换时间(年月日)字段,时分秒不变的实现方法，需要的朋友可以参考下

写法写法1：：

update sas_order_supply_month_pay set

RECEIVE_TIME=REPLACE(RECEIVE_TIME,DATE_FORMAT(RECEIVE_TIME,'%Y-%m-%d'),(select PERIOD_END from sas_task_supply_month_pay_period where belong='1729'

and CREATE_TIME like '%2017-07-12%')) where ORDER_CODE='PO201707130115';

写法写法2：：

update sas_order_supply_month_pay set

说明： s

as_order_supply_month_pay表的RECEIVE_TIME字段格式为"2017-06-16 12:13:16"，sas_task_supply_month_pay_period表的PERIOD_END字段格式为"2017-07-12",

执行后RECEIVE_TIME修改为"2017-07-12 12:13:16"。

错误写法：

update sas_order_supply_month_pay set

RECEIVE_TIME = DATE_FORMAT(concat((select PERIOD_END from sas_task_supply_month_pay_period where belong='1729'

and CREATE_TIME like '%2017-07-12%'),' ',(select DATE_FORMAT(RECEIVE_TIME,'%H:%i:%S') from sas_order_supply_month_pay

where ORDER_CODE='PO201707130115')),"yyyy-MM-dd %H:%i:%S") where ORDER_CODE='PO201707130115';

错误写法报错：

[Err] 1093 - You can't specify target table 'sas_order_supply_month_pay' for update in FROM clause
