How to Get Value in Redis: Simple Guide with Examples

To get a value in Redis, use the GET command followed by the key name. For example, GET mykey returns the value stored at mykey or (nil) if the key does not exist.

Syntax

The basic syntax to get a value from Redis is:

• GET key: Retrieves the value stored at the specified key.
• If the key exists, Redis returns its value as a string.
• If the key does not exist, Redis returns (nil).

redis

GET key

Example

This example shows how to set a key and then get its value using Redis commands.

redis

SET favorite_color blue
GET favorite_color
GET missing_key

Output

"OK"
"blue"
(nil)

Common Pitfalls

Common mistakes when getting values in Redis include:

• Trying to get a value from a key that does not exist, which returns (nil).
• Confusing data types: GET only works with string keys, not hashes or lists.
• Not checking the response for (nil) which means the key is missing.

redis

GET myhash

# Correct way to get a field from a hash:
HGET myhash field1

Output

(error) WRONGTYPE Operation against a key holding the wrong kind of value
"value1"

Quick Reference

Command	Description	Example
GET key	Get the string value of a key	GET username
SET key value	Set the string value of a key	SET username alice
HGET key field	Get the value of a hash field	HGET user:1 name
(nil)	Returned when key does not exist	GET missing_key

Key Takeaways

Use the GET command followed by the key name to retrieve a value in Redis.

GET returns the string value or (nil) if the key does not exist.

GET only works with string keys; use HGET for hash fields.

Always check for (nil) to handle missing keys gracefully.
