How to query data for each month in SQL?
To query data for each month, you can use the DATEPART function in SQL to extract the month from the date field, and then perform grouping and aggregation operations based on the month.
Here is an example query that can retrieve the total sales amount for each month.
SELECT DATEPART(month, order_date) AS month,
SUM(total_amount) AS total_sales
FROM orders
GROUP BY DATEPART(month, order_date)
ORDER BY DATEPART(month, order_date);
In this query, we use the DATEPART function to extract the month from the order_date field and sum the total_amount field. The results are then grouped by month and sorted accordingly. You can modify the query to retrieve other metrics or data for each month based on your needs.
