In this tutorial, we will learn about how to set a new string value at a specified key and returns its old string value. For this we will use a COMMAND – GETSET in redis-cli. This command returns nil, if key does not exist and returns error, if key exist but value stored at the key is not a string. The syntax of redis GETSET command is as follows :-
redis host:post> GETSET <keyname> <value>
(string) reply, representing string value stored at key. (nil) reply, if key does not exist. Error, if key exist and value stored at the key is not a string.
That’s all for how to set a new string value at a key and returns its old string value stored in redis datastore. If you liked it, please share your thoughts in comments section and share it with others too.
