# NOT IN

Test whether a value matches none of the values in a list. expr NOT IN (value,...) is the same as NOT (expr IN (value,...)).

## Syntax

```bnf
expr NOT IN (value,...)
expr NOT IN (subquery)
```

## Description

This is the same as `NOT` (`expr` [IN](/docs/server/reference/sql-structure/operators/comparison-operators/in.md) (value,...)).

With a subquery, `expr NOT IN (subquery)` is the same as `expr <> ALL (subquery)`. See [Subqueries with IN and NOT IN](/docs/server/reference/sql-statements/data-manipulation/selecting-data/subqueries/subqueries-with-in-and-not-in.md).

## Examples

```sql
SELECT 2 NOT IN (0,3,5,7);
+--------------------+
| 2 NOT IN (0,3,5,7) |
+--------------------+
|                  1 |
+--------------------+
```

```sql
SELECT 'wefwf' NOT IN ('wee','wefwf','weg');
+--------------------------------------+
| 'wefwf' NOT IN ('wee','wefwf','weg') |
+--------------------------------------+
|                                    0 |
+--------------------------------------+
```

```sql
SELECT 1 NOT IN ('1', '2', '3');
+--------------------------+
| 1 NOT IN ('1', '2', '3') |
+--------------------------+
|                        0 |
+--------------------------+
```

`NULL`:

```sql
SELECT NULL NOT IN (1, 2, 3);
+-----------------------+
| NULL NOT IN (1, 2, 3) |
+-----------------------+
|                  NULL |
+-----------------------+

SELECT 1 NOT IN (1, 2, NULL);
+-----------------------+
| 1 NOT IN (1, 2, NULL) |
+-----------------------+
|                     0 |
+-----------------------+

SELECT 5 NOT IN (1, 2, NULL);
+-----------------------+
| 5 NOT IN (1, 2, NULL) |
+-----------------------+
|                  NULL |
+-----------------------+
```
