Legal Studies如何在 MySQL 中轉換日期格式？
要轉換日期格式，請使用 STR_TO_DATE() −
mysql> create table DemoTable2010 ( DueDate varchar(20) ); Query OK, 0 rows affected (0.68 sec)
使用插入命令在表中插入一些記錄 −
mysql> insert into DemoTable2010 values('12/10/2019 12:34:00');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable2010 values('12/12/2011 11:00:20');
Query OK, 1 row affected (0.21 sec)
mysql> insert into DemoTable2010 values('31/01/2017 11:00:20');
Query OK, 1 row affected (0.23 sec)使用選擇語句從表中顯示所有記錄 −
mysql> select * from DemoTable2010;
這將產生以下輸出 −
+---------------------+ | DueDate | +---------------------+ | 12/10/2019 12:34:00 | | 12/12/2011 11:00:20 | | 31/01/2017 11:00:20 | +---------------------+ 3 rows in set (0.00 sec)
以下是轉換日期格式的查詢 −
mysql> select str_to_date(DueDate,'%d/%m/%Y %k:%i') from DemoTable2010;
這將產生以下輸出 −
+---------------------------------------+ | str_to_date(DueDate,'%d/%m/%Y %k:%i') | +---------------------------------------+ | 2019-10-12 12:34:00 | | 2011-12-12 11:00:00 | | 2017-01-31 11:00:00 | +---------------------------------------+ 3 rows in set, 3 warnings (0.00 sec)
