Get maximum date from a list of varchar dates in MySQL
Let us first create a table −
mysql> create table DemoTable ( AdmissionDate varchar(100) ); Query OK, 0 rows affected (0.76 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('Sunday, 11 August 2019');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable values('Friday, 18 October 2019');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable values('Thursday, 18 July 2019');
Query OK, 1 row affected (0.23 sec)Display all records from the table using select statement −
mysql> select *from DemoTable ;
This will produce the following output −
+-------------------------+ | AdmissionDate | +-------------------------+ | Sunday, 11 August 2019 | | Friday, 18 October 2019 | | Thursday, 18 July 2019 | +-------------------------+ 3 rows in set (0.00 sec)
Following is the query to get the maximum date from a list of varchar dates inserted above −
mysql> select max(str_to_date(AdmissionDate,'%W, %d %M %Y')) AS MaxDate from DemoTable;
This will produce the following output −
+------------+ | MaxDate | +------------+ | 2019-10-18 | +------------+ 1 row in set (0.04 sec)
