用MySQL STR_TO_DATE替换日期格式
让我们首先创建一个表-
create table DemoTable(DueDate varchar(100));
使用插入命令在表中插入一些记录-
insert into DemoTable values('10-01-2019 10:19:20');
insert into DemoTable values('12-03-2018 11:00:00');
insert into DemoTable values('02-23-2018 04:20:40');使用select语句显示表中的所有记录-
select *from DemoTable;
这将产生以下输出-
+---------------------+ | DueDate | +---------------------+ | 10-01-2019 10:19:20 | | 12-03-2018 11:00:00 | | 02-23-2018 04:20:40 | +---------------------+ 3 rows in set (0.00 sec)
以下是将日期格式替换为MySQLSTR_TO_DATE的查询-
SELECT STR_TO_DATE(REPLACE(DueDate,"'",''), '%c-%e-%Y %T') from DemoTable;
这将产生以下输出-
+-----------------------------------------------------+ | STR_TO_DATE(REPLACE(DueDate,"'",''), '%c-%e-%Y %T') | +-----------------------------------------------------+ | 2019-10-01 10:19:20 | | 2018-12-03 11:00:00 | | 2018-02-23 04:20:40 | +-----------------------------------------------------+ 3 rows in set (0.00 sec)
