Selecting from a MySQL table based on parts of a timestamp?

MySQLMySQLi Database

Let us first create a table −

mysql> create table DemoTable
(
   AdmissionDate timestamp
);
Query OK, 0 rows affected (0.90 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('2007-01-10');
Query OK, 1 row affected (0.34 sec)
mysql> insert into DemoTable values('2015-07-12');
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable values('2017-11-01');
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable values('2019-08-29');
Query OK, 1 row affected (0.08 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+---------------------+
| AdmissionDate       |
+---------------------+
| 2007-01-10 00:00:00 |
| 2015-07-12 00:00:00 |
| 2017-11-01 00:00:00 |
| 2019-08-29 00:00:00 |
+---------------------+
4 rows in set (0.00 sec)

Following is the query to select from a MySQL table based on parts of a timestamp. Here, we are selecting on the basis of year −

mysql> select *from DemoTable where year(AdmissionDate)='2017';

This will produce the following output −

+---------------------+
| AdmissionDate       |
+---------------------+
| 2017-11-01 00:00:00 |
+---------------------+
1 row in set (0.23 sec)
