:::warning

`not` will return all items that do not match a given value. However, if the column is nullable, `NULL` values will not be returned. If you require null values to be returned, use an [`OR`](#or) operator to include `NULL` values.

:::

##### Return all users where `name` does **not** equal `"Eleanor"` **including** users where `name` is `NULL`

```ts
await prisma.user.findMany({
where: {
OR: [
{ name: { not: 'Eleanor' } },
{ name: null }
]
}
})
```

### `in`

Value `n` exists in list.

#### Remarks
:::note

- `null` values are not returned. For example, if you combine `in` and `NOT` to return user whose name is _not_ in the list, users with `null` value names are not returned.
