MySQL MONTH Function: Get The Month Of A Specified Date

MySQL MONTH Function: Get The Month Of A Specified Date

The MONTH() function in MySQL is a date function that returns the month for a given date. The month is returned as an integer ranging from 1 to 12.

Syntax:

MONTH(date)

Here, date is a valid date expression.

Example:

SELECT MONTH('2023-05-12');

This will return 5, because May is the 5th month of the year.

Usage in a Table:

Consider the following orders table:

OrderIDProductOrderDate
1Apples2023-05-12
2Bananas2023-06-15
3Oranges2023-07-20
4Apples2023-05-25
5Bananas2023-06-30

If you want to select all orders that were placed in May, you can use the MONTH() function in the WHERE clause:

SELECT * FROM orders WHERE MONTH(OrderDate) = 5;

This will return all rows where OrderDate is in May:

OrderIDProductOrderDate
1Apples2023-05-12
4Apples2023-05-25

Usage with GROUP BY:

You can also use the MONTH() function with the GROUP BY clause to group orders by month. For example, if you want to count the number of orders placed in each month, you could do this:

SELECT MONTH(OrderDate) AS OrderMonth, COUNT(*) AS NumberOfOrders FROM orders GROUP BY OrderMonth;

This will return a result set with the number of orders placed in each month.

Remember that the MONTH() function will return NULL if the input is not a valid date expression.
