How to compare Year, Month and Day in a MySQL query and display matching records
For this, you can use DATE(). Let us first create a table −
mysql> create table DemoTable864(DueDateTime timestamp); Query OK, 0 rows affected (0.56 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable864 values('2019-01-10 12 −34 −55'); Query OK, 1 row affected (0.26 sec) mysql> insert into DemoTable864 values('2016-12-11 11 −12 −00'); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable864 values('2015-04-01 10 −00 −00'); Query OK, 1 row affected (0.28 sec) mysql> insert into DemoTable864 values('2017-05-20 04 −40 −10'); Query OK, 1 row affected (0.17 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable864;
This will produce the following output −
+---------------------+ | DueDateTime | +---------------------+ |2019-01-10 12 −34 −55| |2016-12-11 11 −12 −00| |2015-04-01 10 −00 −00| |2017-05-20 04 −40 −10| +---------------------+ 4 rows in set (0.00 sec)
Following is the query to compare year, month and day −
mysql> select *from DemoTable864 where date(DueDateTime)='2015-04-01';
This will produce the following output −
+-----------------------+ | DueDateTime | +-----------------------+ | 2015-04-01 10 −00 −00 | +-----------------------+ 1 row in set (0.04 sec)
