给出一个产品库存表,列产品ID,仓库ID和数量,写一个DELETE语句,删除仓库1中所有具有数量0的产品.
Here's the DELETE statement:

```
DELETE FROM product_inventory
WHERE WarehouseID = 1 AND Quantity = 0;
```

This statement will delete all rows from the `product_inventory` table where the `WarehouseID` is 1 and the `Quantity` is 0. Only products located in Warehouse 1 with no inventory will be removed with this statement.
