How to use the MONTH function to get the month of a date in MySQL

MySQL is a popular relational database management system that is widely used in various web applications. When using MySQL for data query, it is often necessary to perform analysis and statistics based on dates. MySQL provides the MONTH function for extracting the month from a date. This article will introduce how to use the MONTH function in MySQL to get the month of a date.

In MySQL, the MONTH function is used to extract the month in the date field. The MONTH function accepts a date parameter and returns the month of that date. The following is the syntax of the MONTH function:
MONTH(date)

where date is a date value or date expression.

The following is a sample table to demonstrate how to use the MONTH function:

CREATE TABLE orders (
   id INT PRIMARY KEY AUTO_INCREMENT,
   product VARCHAR(100) NOT NULL,
   order_date DATE NOT NULL
);

INSERT INTO orders (product, order_date) VALUES
   ('Apple', '2021-01-12'),
   ('Banana', '2021-01-18'),
   ('Orange', '2021-02-05'),
   ('Grapes', '2021-02-15'),
   ('Watermelon', '2021-03-06');

The above sample table orders contains three columns: id (primary key), product (product name) and order_date (order date).

Now, we will use the MONTH function to query the data in the orders table and extract the month in the order_date column. Here is an example query using the MONTH function:

SELECT product, order_date, MONTH(order_date) AS month
FROM orders;

After running the above query, you will get the following results:

+------------+------------+-------+
| product    | order_date | month |
+------------+------------+-------+
| Apple      | 2021-01-12 |     1 |
| Banana     | 2021-01-18 |     1 |
| Orange     | 2021-02-05 |     2 |
| Grapes     | 2021-02-15 |     2 |
| Watermelon | 2021-03-06 |     3 |
+------------+------------+-------+

The above results show the product name, order date, and extracted month. Through the MONTH(order_date) statement, we successfully extracted the month from the order_date column. In this way, we can easily analyze and compile statistics on the data by month.

In addition to querying data, we can also use the MONTH function for conditional filtering. The following is a sample query to filter out orders placed in February:

SELECT product, order_date
FROM orders
WHERE MONTH(order_date) = 2;

After running the above query, you will get the following results:

+--------+------------+
| product| order_date |
+--------+------------+
| Orange | 2021-02-05 |
| Grapes | 2021-02-15 |
+--------+------------+

The above results show the order month Product name and order date for orders placed in February.

Summary:
The MONTH function is a very useful function in MySQL for extracting the month from a date. It can easily carry out date analysis and statistics. Through the MONTH function, we can easily query data for a specific month, and we can also use it in the WHERE statement for conditional filtering. In practical applications, we can use the MONTH function in combination with other functions and conditional statements as needed to achieve more complex date operations and query functions.
