Compare date strings in MySQL
To compare date strings, use STR_TO_DATE() from MySQL.
Let us first create a table −
mysql> create table DemoTable712 ( Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, ArrivalDate varchar(100) ); Query OK, 0 rows affected (0.65 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable712(ArrivalDate) values('10.01.2019');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable712(ArrivalDate) values('11.12.2018');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable712(ArrivalDate) values('01.11.2017');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable712(ArrivalDate) values('20.06.2016');
Query OK, 1 row affected (0.23 sec)Display all records from the table using select statement −
mysql> select *from DemoTable712;
This will produce the following output -
+----+-------------+ | Id | ArrivalDate | +----+-------------+ | 1 | 10.01.2019 | | 2 | 11.12.2018 | | 3 | 01.11.2017 | | 4 | 20.06.2016 | +----+-------------+ 4 rows in set (0.00 sec)
Following is the query to compare date strings −
mysql> select *from DemoTable712 where str_to_date(ArrivalDate,'%d.%m.%Y')='2017-11-01';
This will produce the following output -
+----+-------------+ | Id | ArrivalDate | +----+-------------+ | 3 | 01.11.2017 | +----+-------------+ 1 row in set (0.00 sec)
