@damian, distinct on single column is only supported by postgresql (afaik), if you need to select unique item_id, then you may use FooTable.slice(FooTable.item_id).selectAll().withDistinct() as @oshai stated.
In general where is no need to make distinct on one column, in most cases it is replaceable by group by or distinct on row.
