Kater SQL Functions Date conditions
KATER__IS_NOT_ON
True where the date is not the value.
Family: Date conditions
Syntax
KATER__IS_NOT_ON(field, value)Arguments
| Argument | Description |
|---|---|
field | The date or timestamp to test. |
value | The value to compare with. A value, or a parameter a reader supplies. |
Returns
TRUE or FALSE. It is NULL where the field is empty, so a filter leaves that row out.
Usage notes
- A row whose field is empty is left out too, since the comparison with an empty value is not true.
Example
This Sandbox query reads the sample shop’s orders. The table shows the rows that Kater gave.
SELECT orders.order_date AS "Order Date", EVAL(orders.count_distinct__order_id) AS "Orders"FROM kater_dataset.orders AS ordersWHERE KATER__IS_ON_OR_AFTER(orders.order_date, DATE '2026-09-27') AND KATER__IS_NOT_ON(orders.order_date, DATE '2026-09-28')GROUP BY orders.order_dateORDER BY 1| Order Date | Orders |
|---|---|
| 2026-09-27 | 6 |
| 2026-09-29 | 9 |
| 2026-09-30 | 2 |
