Redis SET command is used to set some string value in redis key. If the key already holds a value, it is overwritten, regardless of its type. Any previous time to live associated with the key is discarded on a successful SET operation.
Basic syntax of redis SET command is shown below:
redis 127.0.0.1:6379> SET KEY_NAME VALUE
Simple string reply. OK, if a value is set to key or Null, if the value does not set.
Return Value Type
redis 127.0.0.1:6379> SET w3resource redis OK
In SET command there are many options available, that modify the behavior of command. Basic syntax of SET command with available options is shown below:
redis 127.0.0.1:6379> SET KEY VALUE [EX seconds] [PX milliseconds] [NX|XX] (integer) 1
redis 127.0.0.1:6379> SET w3resource redis EX 60 NX OK
Above example will set the key w3resource, with an expiry of 60 seconds, if the key does not exist.
