# HRANDFIELD

> Get random fields from a hash.

Use `HRANDFIELD` to get one or more random fields from a hash.

Without a count a single field name is returned, or null when the key does not exist. A positive count returns up to that many distinct fields, capped at the size of the hash, while a negative count returns exactly that many fields chosen independently, so the same field can come up more than once. `WITHVALUES` returns each field together with its value.

Nothing is removed from the hash, which is the difference from [`HGETDEL`](/redis/commands/hash/hgetdel): use this for sampling, random selection, and quick inspection of an unfamiliar hash.

## Syntax

```redis
HRANDFIELD <key> [<count> [WITHVALUES]]
```

## Arguments

| Argument | Required | Repeatable | Description |
| --- | --- | --- | --- |
| `<key>` | Yes | No | Redis key targeted by the command. |
| `<count> [WITHVALUES]` | No | No | Number of fields to return; a negative count may repeat fields. `WITHVALUES` also returns each field's value. |

## Important points

- Pair-based results may be flattened into one alternating array in RESP2 while RESP3 preserves nested pairs or a map.

## Response

The reply reports the result of the operation. Error replies have the same shape in RESP2 and RESP3 and are surfaced as exceptions by the SDKs below.

| Protocol | Reply |
| --- | --- |
| RESP2 | Null bulk string or null array, Bulk string, array of fields, or flat field/value array |
| RESP3 | Null, Bulk string, array of fields, or array of field/value pairs |

<Note>
  Client libraries often decode bulk strings, maps, sets, and numeric strings into language-native values. The table describes the Redis wire reply.
</Note>

## Examples

TCP examples use the TLS `REDIS_URL` from the Upstash console. REST examples use `UPSTASH_REDIS_REST_URL` and `UPSTASH_REDIS_REST_TOKEN`.
