MySQL date format to convert dd.mm.yy to YYYY-MM-DD?
Use STR_TO_DATE() method from MySQL to convert. The syntax is as follows wherein we are using format specifiers. The format specifiers begin with %.
SELECT STR_TO_DATE(yourDateColumnName,'%d.%m.%Y') as anyVariableName FROM yourTableName;
To understand the above syntax, let us create a table. The query to create a table is as follows.
mysql> create table ConvertIntoDateFormat -> ( -> Id int NOT NULL AUTO_INCREMENT, -> LoginDate varchar(30), -> PRIMARY KEY(Id) -> ); Query OK, 0 rows affected (0.47 sec)
Insert some records in the table using insert command. The query is as follows −
mysql> insert into ConvertIntoDateFormat(LoginDate) values('11.01.2019');
Query OK, 1 row affected (0.10 sec)
mysql> insert into ConvertIntoDateFormat(LoginDate) values('10.04.2017');
Query OK, 1 row affected (0.16 sec)
mysql> insert into ConvertIntoDateFormat(LoginDate) values('21.10.2016');
Query OK, 1 row affected (0.12 sec)
mysql> insert into ConvertIntoDateFormat(LoginDate) values('26.09.2018');
Query OK, 1 row affected (0.14 sec)
mysql> insert into ConvertIntoDateFormat(LoginDate) values('25.12.2012');
Query OK, 1 row affected (0.17 sec)Display all records from the table using select statement. The query is as follows−
mysql> select *from ConvertIntoDateFormat;
The following is the output.
+----+------------+ | Id | LoginDate | +----+------------+ | 1 | 11.01.2019 | | 2 | 10.04.2017 | | 3 | 21.10.2016 | | 4 | 26.09.2018 | | 5 | 25.12.2012 | +----+------------+ 5 rows in set (0.00 sec)
The following is the query to format the date to YYYY-MM-DD.
mysql> select str_to_date(LoginDate,'%d.%m.%Y') as DateFormat from ConvertIntoDateFormat;
Here is the output.
+------------+ | DateFormat | +------------+ | 2019-01-11 | | 2017-04-10 | | 2016-10-21 | | 2018-09-26 | | 2012-12-25 | +------------+ 5 rows in set (0.00 sec)
You can also use DATE_FORMAT() method for the same purpose. The query is as follows
mysql> select DATE_FORMAT(STR_TO_DATE(LoginDate,'%d.%m.%Y'), '%Y-%m-%d') as DateFormat from -> ConvertIntoDateFormat;
The following is the output−
+------------+ | DateFormat | +------------+ | 2019-01-11 | | 2017-04-10 | | 2016-10-21 | | 2018-09-26 | | 2012-12-25 | +------------+ 5 rows in set (0.00 sec)
