+ * Inside the $subresult array, we create ['select_expr'] and ['table_ref'] arrays.

+ *    [FROM [table_references]
+ *
+ *
+ * ['select_expr'] is filled with each expression, the key represents the

+ * multiple occurences of the same column).
+ *
+ * ['table_ref'] is filled with each table ref, same thing for the key.

+ * I create all sub-values empty, even if they are
