SQL query to retrieve SUM in various DATE ranges
Solution 1
I would go with the following
SELECT SUM(totalprice), year(date), month(date)
FROM sales
GROUP BY year(date), month(date)
Solution 2
This answer is based on my interpretation of this part of your question:
March, SUM for MArch and the next row should be for April, but there are no items in April yet, so I don't really know how to go about all this.
If you're trying to get all months for a year (say 2013), you need to have a placeholder for months with zero sales. This will list all the months for 2013, even when they don't have sales:
SELECT m.monthnum, SUM(mytable.totalprice)
FROM (
SELECT 1 AS monthnum, 'Jan' as monthname
UNION SELECT 2, 'Feb'
UNION SELECT 3, 'Mar'
UNION SELECT 4, 'Apr'
UNION SELECT 5, 'May'
UNION SELECT 6, 'Jun'
UNION SELECT 7, 'Jul'
UNION SELECT 8, 'Aug'
UNION SELECT 9, 'Sep'
UNION SELECT 10, 'Oct'
UNION SELECT 11, 'Nov'
UNION SELECT 12, 'Dec') m
LEFT JOIN my_table ON m.monthnum = MONTH(mytable.date)
WHERE YEAR(mytable.date) = 2013
GROUP BY m.monthnum
ORDER BY m.monthnum

I have a table with information about sold products, the customer, the date of the purchase and summary of sold units.
The result I am trying to get should be 4 rows where the 1st three are for January, February and March. The last row is for the products that weren't sold in these 3 months.
Here is the table. http://imageshack.us/a/img823/8731/fmlxv.jpg
The table columns are:
id sale_id product_id quantity customer_id payment_method_id total_price date time
So in the result the 1st 3 row would be just:
- January, SUM for January
- February, SUM for February
- March, SUM for MArch and the next row should be for April, but there are no items in April yet, so I don't really know how to go about all this.
Editor's note: based on the linked image, the columns above would be for the year 2013.
