To count or not to count, that is the question
I have this table:
Strawberries 2
Strawberries 3
Strawberries 4
Chocolate 3
Chocolate 4
Chocolate 5
Chocolate 6
Apples 3
Apples 4
Apples 5
Apples 6
My idea is to get the number of items, and the total of items per thing, like so:
Item Number Total
Strawberries 2 9
Strawberries 3 9
Strawberries 4 9
Chocolate 3 18
Chocolate 4 18
Chocolate 5 18
Chocolate 6 18
Apples 3 18
Apples 4 18
Apples 5 18
Apples 6 18
So i'm doing:
SELECT TOP (100) PERCENT item, number, COUNT(number) AS total FROM products
GROUP BY item, number
ORDER BY item
But the numbers i get are all wrong:
Item Number Total
Strawberries 2 6
Strawberries 3 21
Strawberries 4 17
Chocolate 3 1
Chocolate 4 8
Chocolate 5 34
Chocolate 6 1
Apples 3 1
Apples 4 开发者_StackOverflow社区 10
Apples 5 32
Apples 6 1
What am i doing wrong?
SELECT item, number, SUM(number) OVER (PARTITION BY item)
FROM products
ORDER BY
item, number
