--- toc_title: ALL --- # ALL Clause {#select-all} `SELECT ALL` is identical to `SELECT` without `DISTINCT`. - If `ALL` specified, ignore it. - If both `ALL` and `DISTINCT` specified, exception will be thrown. `ALL` can also be specified inside aggregate function with the same effect(noop), for instance: ```sql SELECT sum(ALL number) FROM numbers(10); ``` equals to ```sql SELECT sum(number) FROM numbers(10); ```
