In this tutorial, we will learn about how to check, if a specified element is a member of the set or not. For this we will use a COMMAND – SISMEMBER in redis-cli. The syntax of redis SISMEMBER command is as follows :-
redis host:post> SISMEMBER <key name>
(integer) 1 if element is member of the set. (integer) 0 if element is not member of the set, or if key does not exist. error, if key exist and value stored at the key is not a set.
That’s all for how to check, if a specified element is a member of the set or not in redis datastore. If you liked it, please share your thoughts in comments section and share it with others too.
