# Redis Hset Command [!(#) Redis Hashes](#) The Redis Hset command is used to assign a value to a field in a hash table. If the hash table doesn't exist, a new hash table is created and the HSET operation is performed. If the field already exists in the hash table, the old value will be overwritten. ### Syntax The basic syntax of the redis Hset command is as follows: redis 127.0.0.1:6379> HSET KEY_NAME FIELD VALUE ### Available Version >= 2.0.0 ### Return Value Returns 1 if the field is a new field in the hash table and the value was set successfully. Returns 0 if the field already existed in the hash table and the old value was overwritten by the new value. ### Examples redis 127.0.0.1:6379> HSET myhash field1 "foo" OK redis 127.0.0.1:6379> HGET myhash field1 "foo" redis 127.0.0.1:6379> HSET website google "www.g.cn" # Set a new field(integer) 1 redis 127.0.0.1:6379>HSET website google "www.google.com" # Overwrite an existing field(integer) 0 [!(#) Redis Hashes](#)
