Display MySQL Pricing Chart in Spreadsheet-like Columns - mysql

Question

I'm trying to output a friendly price table in MySQL for export/import into a spreadsheet. Let's use fruits and their price breaks as an example.
Here's a fiddle for the schema I'm referring to:
http://sqlfiddle.com/#!9/c526e3/4
Simply:
Table: fruit
id
name
Table: fruit_pricing
id
fruit_id
min_quantity
max_quantity
price
When executing the query:
SELECT
F.name,
IF(FP.min_quantity = 1, FP.price, '0') as qty_1,
IF(FP.min_quantity = 10, FP.price, '0') as qty_10,
IF(FP.min_quantity = 25, FP.price, '0') as qty_25,
IF(FP.min_quantity = 50, FP.price, '0') as qty_50,
IF(FP.min_quantity = 100, FP.price, '0') as qty_100
FROM Fruit F
LEFT JOIN FruitPricing FP ON FP.fruit_id = F.id
It displays the results like this:
What I'd like to do is group the fruit names so there are only three rows: Apple, Grape, and Orange. Then, I'd like all the 0 values to be replaced with the appropriate quantities. I'm trying to get the same output as the spreadsheet in this screenshot:
Are there any nice tricks for accomplishing this? I'm unsure of the sql-tech-speak for this particular question, making it difficult to search for an answer. I'd be happy to update my question subject if I can and somebody has a better suggestion for it.

Answer 1

SELECT f.name
, SUM(CASE WHEN fp.min_quantity = 1 THEN fp.price ELSE 0 END) qty_1
, SUM(CASE WHEN fp.min_quantity = 10 THEN fp.price ELSE 0 END) qty_10
, SUM(CASE WHEN fp.min_quantity = 25 THEN fp.price ELSE 0 END) qty_25
, SUM(CASE WHEN fp.min_quantity = 50 THEN fp.price ELSE 0 END) qty_50
, SUM(CASE WHEN fp.min_quantity = 100 THEN fp.price ELSE 0 END) qty_100
FROM fruit f
LEFT
JOIN fruitpricing fp
ON fp.fruit_id = f.id
GROUP
BY name;
Although, if it was me, I'd probably just do the following, and handle any remaining display issues in the presentation layer...
SELECT f.name
, fp.min_quantity
, SUM(fp.price) qty
FROM fruit f
LEFT
JOIN fruitpricing fp
ON fp.fruit_id = f.id
GROUP
BY name
, min_quantity;
