How to Use HVALS Command in Redis: Syntax and Examples

Use the HVALS command in Redis to retrieve all the values stored in a hash at a given key. It returns a list of all values without the field names. The syntax is HVALS key where key is the hash name.

Syntax

The HVALS command retrieves all values from a hash stored at the specified key.

• key: The name of the hash from which you want to get all values.

It returns a list of values without the field names.

HVALS key

Example

This example shows how to create a hash with fields and values, then use HVALS to get all the values.

redis

127.0.0.1:6379> HSET user:1000 name "Alice" age "30" city "Paris"
(integer) 3
127.0.0.1:6379> HVALS user:1000
1) "Alice"
2) "30"
3) "Paris"

Output

1) "Alice"
2) "30"
3) "Paris"

Common Pitfalls

Common mistakes when using HVALS include:

• Using HVALS on a key that does not exist returns an empty list.
• Using HVALS on a key that is not a hash returns an error.
• Expecting field names along with values; HVALS returns only values.

redis

127.0.0.1:6379> HVALS non_existing_hash
(empty list or set)

127.0.0.1:6379> SET mykey "value"
OK
127.0.0.1:6379> HVALS mykey
(error) WRONGTYPE Operation against a key holding the wrong kind of value

Output

(empty list or set)
(error) WRONGTYPE Operation against a key holding the wrong kind of value

Quick Reference

Command	Description	Return Type
HVALS key	Returns all values in the hash stored at key	Array of values
HGET key field	Returns the value of a specific field in the hash	Single value or nil
HKEYS key	Returns all field names in the hash	Array of fields

Key Takeaways

Use HVALS to get all values from a Redis hash without field names.

HVALS returns an empty list if the hash key does not exist.

Do not use HVALS on keys that are not hashes to avoid errors.

HVALS output is a list of values only, no field names included.
