How to select part of a Timestamp in a MySQL Query?

MySQLMySQLi Database

To select part of a timestamp in a query, you need to use YEAR() function. The syntax is as follows in MySQL.

select YEAR(yourTimestampColumnName) as anyAliasName from yourTableName;

To understand the above syntax, let us create a table. The query to create a table is as follows −

mysql> create table SelectPartOfTimestampDemo
   -> (
   -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   -> ShippingTime TIMESTAMP
   -> );
Query OK, 0 rows affected (1.11 sec)

Now you can insert some records in the table using insert command. The query is as follows −

mysql> insert into SelectPartOfTimestampDemo(ShippingTime) values(now());
Query OK, 1 row affected (0.20 sec)
mysql> insert into SelectPartOfTimestampDemo(ShippingTime)
values(date_add(now(),interval -2 year));
Query OK, 1 row affected (0.17 sec)
mysql> insert into SelectPartOfTimestampDemo(ShippingTime)
values(date_add(now(),interval -3 year));
Query OK, 1 row affected (0.18 sec)
mysql> insert into SelectPartOfTimestampDemo(ShippingTime)
values(date_add(now(),interval -1 year));
Query OK, 1 row affected (0.18 sec)
mysql> insert into SelectPartOfTimestampDemo(ShippingTime)
values(date_add(now(),interval 1 year));
Query OK, 1 row affected (0.16 sec)
mysql> insert into SelectPartOfTimestampDemo(ShippingTime)
values(date_add(now(),interval 2 year));
Query OK, 1 row affected (0.48 sec)
mysql> insert into SelectPartOfTimestampDemo(ShippingTime)
values(date_add(now(),interval 3 year));
Query OK, 1 row affected (0.10 sec)

Display all records from the table using a select statement. The query is as follows −

mysql> select *from SelectPartOfTimestampDemo;

The following is the output −

+----+---------------------+
| Id | ShippingTime        |
+----+---------------------+
|  1 | 2019-02-08 15:03:27 |
|  2 | 2017-02-08 15:03:50 |
|  3 | 2016-02-08 15:04:03 |
|  4 | 2018-02-08 15:04:06 |
|  5 | 2020-02-08 15:04:10 |
|  6 | 2021-02-08 15:04:24 |
|  7 | 2022-02-08 15:04:30 |
+----+---------------------+
7 rows in set (0.00 sec)

Here is the query to select part of a timestamp using YEAR() function −

mysql> select YEAR(ShippingTime) as PartOfTimeStamp from SelectPartOfTimestampDemo;

The following is the output −

+-----------------+
| PartOfTimeStamp |
+-----------------+
|            2019 |
|            2017 |
|            2016 |
|            2018 |
|            2020 |
|            2021 |
|            2022 |
+-----------------+
7 rows in set (0.00 sec)
