Question

I have a mysql table like this

PRODUCT
-------
product_id: 1 | name: product .... product_id: 2 | name: product2 .. etc etc

then i have another table

PROPERTY
---
id: 1 | name: red | product_id: 1 .... id: 2 | name: large | product_id: 1 ..... id: 3 | name : brown | product_id: 2 .... and so on ...

How can i select a product with 2 property?

For example i want to take a product with RED and LARGE property

i tried

SELECT * FROM product
JOIN property USING (product_id)
WHERE property.name = "red" AND property.name = "large" ....

but obviusly it doesn’t work 🙂

thanks for the help and sorry for my english!

Answer 1

you need to count its instances of its record

SELECT  a.productname
FROM    product a
        INNER JOIN property b
            on a.product_ID = b.product_ID
WHERE b.name IN ('red', 'large')
GROUP BY a.productname
HAVING COUNT(a.productname) = 2

if you click the demo, you can see the differences between grouping the result and by regular filetering using IN
