Compare only day and month with date field in MySQL?
You can compare only day and month with date field in MySQL with the help of DATE_FORMAT().
The syntax is as follows
select *from yourTableName
WHERE DATE_FORMAT(yourColumnName, '%m-%d') = DATE_FORMAT('yourValue', '%m-%d') and yourCondition;
To understand the above syntax, let us create a table. The query to create a table is as follows
mysql> create table compareDayAndMonthDemo -> ( -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> compareDayAndTime date -> ); Query OK, 0 rows affected (0.49 sec)
Insert some records in the table using insert command.
The query is as follows
mysql> insert into compareDayAndMonthDemo(compareDayAndTime) values('2014-01-31');
Query OK, 1 row affected (0.20 sec)
mysql> insert into compareDayAndMonthDemo(compareDayAndTime) values('2014-10-11');
Query OK, 1 row affected (0.16 sec)
mysql> insert into compareDayAndMonthDemo(compareDayAndTime) values('2016-09-12');
Query OK, 1 row affected (0.08 sec)
mysql> insert into compareDayAndMonthDemo(compareDayAndTime) values('2017-04-25');
Query OK, 1 row affected (0.08 sec)
mysql> insert into compareDayAndMonthDemo(compareDayAndTime) values('2018-12-25');
Query OK, 1 row affected (0.08 sec)
mysql> insert into compareDayAndMonthDemo(compareDayAndTime) values('2019-02-27');
Query OK, 1 row affected (0.07 sec)
Display all records from the table using select statement.
The query is as follows
mysql> select *from compareDayAndMonthDemo;
The following is the output
+----+-------------------+ | Id | compareDayAndTime | +----+-------------------+ | 1 | 2014-01-31 | | 2 | 2014-10-11 | | 3 | 2016-09-12 | | 4 | 2017-04-25 | | 5 | 2018-12-25 | | 6 | 2019-02-27 | +----+-------------------+ 6 rows in set (0.00 sec)
Here is the query to compare only day and month
mysql> select *from compareDayAndMonthDemo
-> WHERE DATE_FORMAT(compareDayAndTime, '%m-%d') = DATE_FORMAT('2019-01-31', '%m-%d') and Id=1;
The following is the output
+----+-------------------+ | Id | compareDayAndTime | +----+-------------------+ | 1 | 2014-01-31 | +----+-------------------+ 1 row in set (0.00 sec)
If you want only day and month, then use the below query
mysql> select DATE_FORMAT(compareDayAndTime, '%m-%d') AS DayAndMonthOnly from compareDayAndMonthDemo
-> WHERE DATE_FORMAT(compareDayAndTime, '%m-%d') = DATE_FORMAT('2019-01-31', '%m-%d') and Id=1;
The following is the output
+-----------------+ | DayAndMonthOnly | +-----------------+ | 01-31 | +-----------------+ 1 row in set (0.00 sec)
