# OCT

## Syntax

```bnf
OCT(N)
```

## Description

Returns a string representation of the octal value of N, where N is a longlong ([BIGINT](/docs/server/reference/data-types/numeric-data-types/bigint.md)) number. This is equivalent to [CONV(N,10,8)](/docs/server/reference/sql-functions/numeric-functions/conv.md). Returns `NULL` if N is `NULL`.

## Examples

```sql
SELECT OCT(34);
+---------+
| OCT(34) |
+---------+
| 42      |
+---------+

SELECT OCT(12);
+---------+
| OCT(12) |
+---------+
| 14      |
+---------+
```
