Question

对于以下查询

SELECT 
Now() + INTERVAL FLOOR(RAND()*(1000-5+1)+5) DAY as 'Due Date',
device_serial as "Device Serial",
customer_name as "Customer",
error_code as 'Error Code',
resolutiom as 'Resolution'
FROM preventive_maintenance
ORDER BY 'Due Date' desc
LIMIT 25

如何解析“到期日”以2019年2月2日的格式显示

Answer 1

我认为最好在应用程序代码中执行此操作，可以根据最终用户的语言环境将其呈现，但是如果必须在MySQL中执行，则DATE_FORMAT是要使用的函数，例如：

SELECT DATE_FORMAT('2019-02-02','%a-%b-%y') x;
+------------+
| x          |
+------------+
| Sat-Feb-19 |
+------------+

Answer 2

我已经使用CURDATE（）代替了Now（）

SELECT 
DATE_FORMAT(DATE_ADD(curdate(), INTERVAL FLOOR(RAND()*(1000-5+1)+5) DAY), '%d-%b-%y') as 'Due Date',
device_serial as "Device Serial",
customer_name as "Customer",
error_code as 'Error Code',
resolutiom as 'Resolution'
FROM preventive_maintenance
ORDER BY 'Due Date' desc
LIMIT 25

SQL Now（）仅解析日期
