GET key

Available since 1.0.0.

Time complexity: O(1)

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 GET only handles string values.

*Return value

Bulk string reply: the value of key, or nil when key does not exist.

*Examples

redis> GET nonexisting 

  1. (nil)

redis> SET mykey "Hello" 

  1. "OK"

redis> GET mykey 

  1. "Hello"
redis>
