Converting date from 'dd/mm/yyyy' to 'yyyymmdd' in MySQL

To convert date from 'dd/mm/yyyy' to 'yyyymmdd', you can use the date_format() method. Let us first create a table −

mysql> create table DemoTable (    Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,    Admissiondate varchar(200) ); Query OK, 0 rows affected (0.54 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable(Admissiondate) values('21/10/2014'); Query OK, 1 row affected (0.22 sec) mysql> insert into DemoTable(Admissiondate) values('01/12/2016'); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable(Admissiondate) values('31/01/2017'); Query OK, 1 row affected (0.14 sec)

Following is the query to display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+----+---------------+ | Id | Admissiondate | +----+---------------+ | 1 | 21/10/2014 | | 2 | 01/12/2016 | | 3 | 31/01/2017 | +----+---------------+ 3 rows in set (0.00 sec)

Following is the query to convert date from 'dd/mm/yyyy' to 'yyyymmdd' −

mysql> select date_format(str_to_date(Admissiondate,'%d/%m/%Y'),'%Y%m%d') from DemoTable;

This will produce the following output −

+-------------------------------------------------------------+ | date_format(str_to_date(Admissiondate,'%d/%m/%Y'),'%Y%m%d') | +-------------------------------------------------------------+ | 20141021 | | 20161201 | | 20170131 | +-------------------------------------------------------------+ 3 rows in set (0.00 sec)
