### Running Queries
Query uses the same interface as CodeIgniter's [Active Record class](http://codeigniter.com/user_guide/database/active_record.html). However, it does not implement the `select_` methods, `count_all_results`, `distinct`, `having`, `or_having`, `get_compiled_query`, `insert_batch`, `update_batch`, or `count_all` methods.
