# HPERSIST

> Remove field expiration.

Use `HPERSIST` to remove the expiration from hash fields so that they stop being deleted automatically.

The reply holds one status code per requested field, in order: `1` when an expiration was removed, `-1` when the field exists but had no expiration, and `-2` when the field or the key does not exist. This is how a field set by [`HEXPIRE`](/docs/redis/commands/hash/hexpire) or [`HSETEX`](/docs/redis/commands/hash/hsetex) is promoted from temporary to permanent without rewriting its value.

`FIELDS <numfields>` introduces the field list and the count must match.

## Syntax

```redis theme={"system"}
HPERSIST <key> FIELDS <numfields> <field> [<field> ...]
```

## Arguments

| Argument                                   | Required | Repeatable | Description                                                               |
| ------------------------------------------ | -------- | ---------- | ------------------------------------------------------------------------- |
| `<key>`                                    | Yes      | No         | Redis key targeted by the command.                                        |
| `FIELDS <numfields> <field> [<field> ...]` | Yes      | No         | Fields to target. Give the field count first, then that many field names. |

## 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    | Array of integer status codes, one per field |
| RESP3    | Array of integer status codes, one per field |

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

## Examples

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