How can the values of a hash be retrieved in Redis?

To obtain the value of a hash in Redis, you can use the HGET command, with the following syntax:

Get the value of a field in a key

In this case, key represents the key of the hash and field represents the name of the field to be retrieved.

For example, retrieve the value of the field “name” from a hash named “user”.

Retrieve the username.

To retrieve the values of all fields in a hash, you can use the HGETALL command, with the following syntax:

Retrieve all the fields and values of the specified key.

For example, retrieve the values of all fields in the hash named user.

Get all information about the user.

This way, you can access all the values in the hash.
