MySQL - MONTH() Function


The DATE, DATETIME and TIMESTAMP datatypes in MySQL are used to store the date, date and time, time stamp values respectively. Where a time stamp is a numerical value representing the number of milliseconds from '1970-01-01 00:00:01' UTC (epoch) to the specified time. MySQL provides a set of functions to manipulate these values.

The MYSQL MONTH() function is used to retrieve and return the MONTH of the given date or, date time expression. This function returns a numerical value ranging from 1 to 12 representing the month (January to December).

Syntax

Following is the syntax of the above function –

MONTH(date);

Where, date is the date value from which you need to retrieve the month.

Example 1

Following example demonstrates the usage of the MONTH() function –

mysql> SELECT MONTH('2019-05-25');
+---------------------+
| MONTH('2019-05-25') |
+---------------------+
|                   5 |
+---------------------+
1 row in set (0.18 sec)

Example 2

Following is another example of this function –

mysql> SELECT MONTH('2008-09-17');
+---------------------+
| MONTH('2008-09-17') |
+---------------------+
|                   9 |
+---------------------+
1 row in set (0.00 sec)

Example 3

If the month value in the given date is 0 this function returns 0 —

mysql> SELECT MONTH('2017-00-00');
+---------------------+
| MONTH('2017-00-00') |
+---------------------+
|                    0|
+---------------------+
1 row in set (0.00 sec)
mysql> SELECT MONTH('1789-00-07');
+---------------------+
| MONTH('1789-00-07') |
+---------------------+
|                   0 |
+---------------------+
1 row in set (0.00 sec)

Example 4

If you pass an empty string or a non-string value as an argument this function returns NULL.

mysql> SELECT MONTH('');
+-----------+
| MONTH('') |
+-----------+
| NULL      |
+-----------+
1 row in set, 1 warning (0.00 sec)
mysql> SELECT MONTH(1990-11-11);
+-------------------+
| MONTH(1990-11-11) |
+-------------------+
| NULL              |
+-------------------+
1 row in set, 1 warning (0.00 sec)

Example 5

We can also pass the date-time expression as an argument to this function –

mysql> SELECT MONTH('2015-09-05 09:40:45.2300');
+-----------------------------------+
| MONTH('2015-09-05 09:40:45.2300') |
+-----------------------------------+
|                                 9 |
+-----------------------------------+
1 row in set (0.00 sec)

Example 6

In the following example we are retrieving the month (number) from the current date —

mysql> SELECT MONTH(CURDATE());
+------------------+
| MONTH(CURDATE()) |
+------------------+
|                7 |
+------------------+
1 row in set (0.00 sec)

Example 7

In the following example we are retrieving the month (number) from the current timestamp —

mysql> SELECT MONTH(CURRENT_TIMESTAMP());
+----------------------------+
| MONTH(CURRENT_TIMESTAMP()) |
+----------------------------+
|                          7 |
+----------------------------+
1 row in set (0.00 sec)

Example 8

You can also pass the column name as an argument to this function. Let us create a table with name MyPlayers in MySQL database using CREATE statement as shown below –

mysql> CREATE TABLE MyPlayers(
	ID INT,
	First_Name VARCHAR(255),
	Last_Name VARCHAR(255),
	Date_Of_Birth date,
	Place_Of_Birth VARCHAR(255),
	Country VARCHAR(255),
	PRIMARY KEY (ID)
);
Now, we will insert 7 records in MyPlayers table using INSERT statements:
mysql> insert into MyPlayers values(1, 'Shikhar', 'Dhawan', DATE('1981-12-05'), 'Delhi', 'India');
mysql> insert into MyPlayers values(2, 'Jonathan', 'Trott', DATE('1981-04-22'), 'CapeTown', 'SouthAfrica');
mysql> insert into MyPlayers values(3, 'Kumara', 'Sangakkara', DATE('1977-10-27'), 'Matale', 'Srilanka');
mysql> insert into MyPlayers values(4, 'Virat', 'Kohli', DATE('1988-11-05'), 'Delhi', 'India');
mysql> insert into MyPlayers values(5, 'Rohit', 'Sharma', DATE('1987-04-30'), 'Nagpur', 'India');
mysql> insert into MyPlayers values(6, 'Ravindra', 'Jadeja', DATE('1988-12-06'), 'Nagpur', 'India');
mysql> insert into MyPlayers values(7, 'James', 'Anderson', DATE('1982-06-30'), 'Burnley', 'England');

Following query retrieves and prints the month (number) from all the entities of the Date_Of_Birth column of the table MyPlayers —

mysql> SELECT First_Name, Last_Name, Date_Of_Birth, Country,
MONTH(Date_Of_Birth) FROM MyPlayers;
+------------+------------+---------------+-------------+----------------------+
| First_Name | Last_Name  | Date_Of_Birth | Country     | MONTH(Date_Of_Birth) |
+------------+------------+---------------+-------------+----------------------+
| Shikhar    | Dhawan     | 1981-12-05    | India       |                   12 |
| Jonathan   | Trott      | 1981-04-22    | SouthAfrica |                   4  |
| Kumara     | Sangakkara | 1977-10-27    | Srilanka    |                   10 |
| Virat      | Kohli      | 1988-11-05    | India       |                   11 |
| Rohit      | Sharma     | 1987-04-30    | India       |                    4 |
| Ravindra   | Jadeja     | 1988-12-06    | India       |                   12 |
| James      | Anderson   | 1982-06-30    | England     |                    6 |
+------------+------------+---------------+-------------+----------------------+
7 rows in set (0.00 sec)

Example 9

Suppose we have created a table named dispatches_data with 5 records in it using the following queries –

mysql> CREATE TABLE dispatches_data(
	ProductName VARCHAR(255),
	CustomerName VARCHAR(255),
	DispatchTimeStamp timestamp,
	Price INT,
	Location VARCHAR(255)
);
insert into dispatches_data values('Key-Board', 'Raja', TIMESTAMP('2019-05-04', '15:02:45'), 7000, 'Hyderabad');
insert into dispatches_data values('Earphones', 'Roja', TIMESTAMP('2019-06-26', '14:13:12'), 2000, 'Vishakhapatnam');
insert into dispatches_data values('Mouse', 'Puja', TIMESTAMP('2019-12-07', '07:50:37'), 3000, 'Vijayawada');
insert into dispatches_data values('Mobile', 'Vanaja' , TIMESTAMP ('2018-03-21', '16:00:45'), 9000, 'Chennai');
insert into dispatches_data values('Headset', 'Jalaja' , TIMESTAMP('2018-12-30', '10:49:27'), 6000, 'Goa');

Following query retrieves the month values (numbers) from the DispatchTimeStamp column —

mysql> SELECT ProductName, CustomerName, DispatchTimeStamp, Price,
MONTH(DispatchTimeStamp) FROM dispatches_data;
+-------------+--------------+---------------------+-------+--------------------------+
| ProductName | CustomerName | DispatchTimeStamp   | Price | MONTH(DispatchTimeStamp) |
+-------------+--------------+---------------------+-------+--------------------------+
| Key-Board   | Raja         | 2019-05-04 15:02:45 | 7000  |                        5 |
| Earphones   | Roja         | 2019-06-26 14:13:12 | 2000  |                        6 |
| Mouse       | Puja         | 2019-12-07 07:50:37 | 3000  |                       12 |
| Mobile      | Vanaja       | 2018-03-21 16:00:45 | 9000  |                        3 |
| Headset     | Jalaja       | 2018-12-30 10:49:27 | 6000  |                       12 |
+-------------+--------------+---------------------+-------+--------------------------+
5 rows in set (0.00 sec)

Example 10

Suppose we have created a table named SubscriberDetails with 5 records in it using the following queries –

mysql> CREATE TABLE SubscriberDetails (
	SubscriberName VARCHAR(255),
	PackageName VARCHAR(255),
	SubscriptionTimeStamp timestamp
);
insert into SubscriberDetails values('Raja', 'Premium', TimeStamp('2020-10-21 20:53:49'));
insert into SubscriberDetails values('Roja', 'Basic', TimeStamp('2020-11-26 10:13:19'));
insert into SubscriberDetails values('Puja', 'Moderate', TimeStamp('2021-03-07 05:43:20'));
insert into SubscriberDetails values('Vanaja', 'Basic', TimeStamp('2021-02-21 16:36:39'));
insert into SubscriberDetails values('Jalaja', 'Premium', TimeStamp('2021-01-30 12:45:45'));

Following query retrieves and displays the subscription month for all the records —

mysql> SELECT SubscriberName, PackageName, SubscriptionTimeStamp,
MONTH(SubscriptionTimeStamp) FROM SubscriberDetails;
-----------------+-------------+-----------------------+------------------------------+
| SubscriberName | PackageName | SubscriptionTimeStamp | MONTH(SubscriptionTimeStamp) |
+----------------+-------------+-----------------------+------------------------------+
| Ram            | Premium     | 2020-10-21 20:53:49   |                           10 |
| Rahman         | Basic       | 2020-11-26 10:13:19   |                           11 |
| Robert         | Moderate    | 2021-03-07 05:43:20   |                            3 |
| Radha          | Basic       | 2021-02-21 16:36:39   |                            2 |
| Rajiya         | Premium     | 2021-01-30 12:45:45   |                            1 |
