I don't see how join would help me
I don't really have parent/child relationship, the only common field is
product_id
For example, for different sheos of same model, img and title is different
for each model :
[
{"product_id":1, "offer_id":1,"title":"Converse all star - red - 8",
"attribute_size":"8", "attribute_color":"red", "price":49},
{"product_id":1, "offer_id":2,"title":"Converse all star - red - 9",
"attribute_size":"9", "attribute_color":"red", "price":49},
{"product_id":1, "offer_id":3,"title":"Converse all star - blue - 8",
"attribute_size":"8", "attribute_color":"blue", "price":49},
{"product_id":1, "offer_id":4,"title":"Converse all star - blue - 9",
"attribute_size":"9", "attribute_color":"blue", "price":49}
]
How can i index/query for using join in order to have only one shoe per
model (the best price for example)?
