public class SqlNameContext extends Object
Given a column, we need to determinate to which table it belongs to. This is not always simple, as SQL queries can use "aliases".

This problem is further exacerbated by: 1) a SELECT can have many sub-SELECTs inside it, each one defining their own independent aliases 2) a SQL command might not have all the necessary info to infer the right table for a column. In those (valid) cases of ambiguity, we must refer to the schema. WARNING: we lowercase all names of tables and columns, as SQL is (should be?) case insensitive
