Convert Date not in a proper format with MySQL?

Assume that the date is in varchar data type i.e. not in the date format.

Let us first create a table. Following is the query −

mysql> create table convertDateDemo
   -> (
   -> AdmissionDate varchar(200)
   -> );
Query OK, 0 rows affected (0.63 sec)

Following is the query to insert some records in the table using insert command −

mysql> insert into convertDateDemo values('April 04 2019');
Query OK, 1 row affected (0.18 sec)

mysql> insert into convertDateDemo values('May 05 2018');
Query OK, 1 row affected (0.16 sec)

mysql> insert into convertDateDemo values('January 01 2012');
Query OK, 1 row affected (0.12 sec)

mysql> insert into convertDateDemo values('June 12 2016');
Query OK, 1 row affected (0.16 sec)

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

mysql> select * from convertDateDemo;

This will produce the following output −

+-----------------+
| AdmissionDate   |
+-----------------+
| April 04 2019   |
| May 05 2018     |
| January 01 2012 |
| June 12 2016    |
+-----------------+
4 rows in set (0.00 sec)

Here is the query to convert date with MySQL −

mysql> select STR_TO_DATE(AdmissionDate, '%M %e %Y %l:%i%p') AS ConvertDate from
convertDateDemo;

This will produce the following output −

+---------------------+
| ConvertDate         |
+---------------------+
| 2019-04-04 00:00:00 |
| 2018-05-05 00:00:00 |
| 2012-01-01 00:00:00 |
| 2016-06-12 00:00:00 |
+---------------------+
4 rows in set (0.05 sec)
