57   sql = prepared_sql
58   prepared_args.freeze
59   ps = bind(bind_vars)
60   ps.clone(:bind_arguments=>ps.map_to_prepared_args(ps.opts[:bind_vars]), :sql=>sql, :prepared_sql=>sql).run(&block)
61 end
prepared_sql()

Override the given *_sql method based on the type, and cache the result of the sql.
