## Syntax

```bnf
&
```

## Description

Bitwise AND. Converts the values to binary and compares bits. Only if both the corresponding bits are 1 is the resulting bit also 1.

See also [bitwise OR](/docs/server/reference/sql-functions/secondary-functions/bit-functions-and-operators/bitwise-or.md).

## Examples

```sql
SELECT 2&1;
+-----+
| 2&1 |
+-----+
|   0 |

SELECT 3&1;
+-----+
| 3&1 |
+-----+
|   1 |
+-----+

SELECT 29 & 15;
