mysql - Finding all other Objects with same Joined Attributes -


I have a product table, and then the product type and product option tables (include in tables for other tables).

Looking at one product, I want to find all other products where the product's options (i.e., ProductOptions.product_id == product.id) and ProductTypes are the same.

Most Well we can get all the product type and product options, then to find the ID == id to join the table for each; But it seems irreversible and we feel that one way to do this should be a bit clearer.

How would you find other products where all the options and types included in the original product match?

using Rail 3.x / ruby ​​1.9.3.

I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
