GET

Syntax

GET key

Description

The GET command retrieves the string value associated with a key. If the key does not exist, GET returns nil (null bulk string).

Arguments

• key (required): The name of the key to retrieve.

Return Value

Returns a Bulk String:

• The value of the key if it exists
• nil (null bulk string) if the key does not exist

Examples

Getting an Existing Key

SET mykey "Hello ECHO DB"
GET mykey

Response:

OK
"Hello ECHO DB"

Getting a Non-Existent Key

GET nonexistent

Response:

(nil)

Getting a Key After Deletion

SET mykey "value"
DEL mykey
GET mykey

Response:

OK

Notes

• GET only works with string values. If the key holds a list, you'll get a WRONGTYPE error
• Keys are case-sensitive
• Returns nil if the key doesn't exist or has expired
