Syntax

GET key

Available since:

Redis Open Source 1.0.0

Time complexity:

O(1)

ACL categories:

@read, @string, @fast,

Get the value of key. If the key does not exist the special value nil is returned. An error is returned if the value stored at key is not a string, because GETonly handles string values.

Examples

GET nonexisting SET mykey "Hello" GET mykey
