If there are multiple matching rows in the table, then `ALL` returns all of them. `SELECT ALL` is identical to `SELECT` without `DISTINCT` . 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);
```
