I have a database schema, where I have a Product, Category, CategoryFeature, and an ProductCategoryFeatureValue.
I have this query that works as desired, but it seems like there should be a better way to accomplish what I want:

I\'ve tried following the syntax suggested here, but it doesn\'t work for my query. Here\'s what I currently have:
I\'m trying to select products based on facets for a product category page. The basic structure is: Product_Facets
I have this: $this->db->select(\'(select var_value from contents where table = \"products\" and table_id = products.id and var_name = \"image\" and n开发者_JAVA技巧ame = \"images\" order by id
I have this table in a postgres 8.4 database: CREATE TABLE public.dummy ( address_id SERIAL, addr1 character(40),

What I am trying to do is get the results from the first query pass them into an array and then use them in a sub query. Both queries work separately if I input the id\'s into the sub query manually.
I\'m working through some old code (not mine) and I need to optimise the following query because it is taking a long time to complete. My guess is the subquery is causing it
