MySQL ডেট ফরম্যাট করা এবং Year-Month-Day-এ রূপান্তর

প্রথমে একটি টেবিল তৈরি করি:

mysql> create table DemoTable666(AdmissionDate varchar(200));
Query OK, 0 rows affected (0.57 sec)

বিভিন্ন ফরম্যাটে ডেট ইনসার্ট করি:

mysql> insert into DemoTable666 values('Sat,20 Jul 2019 04:29:35');
Query OK, 1 row affected (1.12 sec)
mysql> insert into DemoTable666 values('Fri,02 Oct 2018 12:19:15');
Query OK, 1 row affected (1.05 sec)
mysql> insert into DemoTable666 values('Sun,01 Aug 2016 11:10:05');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable666 values('Fri, 06 Nov 2015 04:06:05 -0500');
Query OK, 1 row affected (0.24 sec)

সব রেকর্ড দেখি:

mysql> select *from DemoTable666;

আউটপুট:

ডেট ফরম্যাট Year-Month-Day-এ রূপান্তরের ক্যোয়ারি:

mysql> select DATE_FORMAT(STR_TO_DATE(AdmissionDate, '%a, %d %b %Y %H:%i:%S'),'%Y-%m-%d %H:%i:%s') AS MyDate from DemoTable666;

আউটপুট:
