Redis简单增删改查例子
例一：字符串的增删改查
#增加一个
key
为ay_key的值
127.0.0.1:6379>
set
ay_key
"ay"
OK
#查询ay_key的值
127.0.0.1:6379> get ay_key
"ay"
#修改ay_key的值
127.0.0.1:6379>
set
ay_key
"new_ay"
OK
127.0.0.1:6379> get ay_key
"new_ay"
#修改ay_key名称
127.0.0.1:6379> rename ay_key new_ay_key
OK
127.0.0.1:6379> keys *
1)
"new_ay_key"
#删除ay_key
127.0.0.1:6379> del ay_key
(
integer
) 0
#查询是否存在ay_key 0
127.0.0.1:6379> exists ay_key
(
integer
) 0
例二：Set集合的增删改查
#删除当前选择数据库中的所有
key
127.0.0.1:6379> flushdb
OK
#生成
set
集合，添加4个数据
127.0.0.1:6379> sadd set_ay_key
"ay"
"al"
"xy"
"xl"
(
integer
) 4
#查询
set
里面所有值
127.0.0.1:6379> smembers set_ay_key
1)
"xy"
2)
"al"
3)
"ay"
4)
"xl"
#删除value为
"xl"
, 返回 1 如果没有返回 0
127.0.0.1:6379> srem set_ay_key
"xl"
(
integer
) 1
127.0.0.1:6379> smembers set_ay_key
1)
"xy"
2)
"al"
3)
"ay"
#添加value为
"xl"
127.0.0.1:6379> sadd set_ay_key
"xl"
(
integer
) 1
127.0.0.1:6379> smembers set_ay_key
1)
"xy"
2)
"al"
3)
"ay"
4)
"xl"
#添加value为
"xl"
添加不进去，但也不报错，
set
是不允许重复的
127.0.0.1:6379> sadd set_ay_key
"xl"
(
integer
) 0
#不多解释
127.0.0.1:6379> sadd set_ay_key
"xl"
(
integer
) 0
#不多解释
127.0.0.1:6379> sadd set_ay_key
"xl"
(
integer
) 0
例三：List集合的增删改查
#添加
key
为list_ay_key的list集合
127.0.0.1:6379> lpush list_ay_key
"ay"
"al"
"xy"
"xl"
(
integer
) 4
#查询
key
为list_ay_key的集合
127.0.0.1:6379> lrange list_ay_key 0 -1
1)
"xl"
2)
"xy"
3)
"al"
4)
"ay"
#往list尾部添加元素
127.0.0.1:6379> rpush list_ay_key
"together"
(
integer
) 5
#往list头部添加元素
127.0.0.1:6379> lpush list_ay_key
"first"
(
integer
) 6
#查询list集合
127.0.0.1:6379> lrange list_ay_key 0 -1
1)
"first"
2)
"xl"
3)
"xy"
4)
"al"
5)
"ay"
6)
"together"
#更新
index
为0的值
127.0.0.1:6379> lset list_ay_key 0
"update_first"
OK
127.0.0.1:6379> lrange list_ay_key 0 -1
1)
"update_first"
2)
"xl"
3)
"xy"
4)
"al"
5)
"ay"
6)
"together"
#删除
index
为1上的值
127.0.0.1:6379> lrem list_ay_key 1
"update_first"
(
integer
) 1
127.0.0.1:6379> lrange list_ay_key 0 -1
1)
"xl"
2)
"xy"
3)
"al"
4)
"ay"
5)
"together"
例四：Hash集合(类似
Java)的增删改查
127.0.0.1:6379> flushdb
OK
#生成hash集合，并添加
key
为uuid_one value 为
"12345"
127.0.0.1:6379> hset hash_ay_key
"uuid_one"
"12345"
(
integer
) 1
127.0.0.1:6379> hlen hash_ay_key
(
integer
) 1
#返回集合所有的
key
127.0.0.1:6379> hkeys hash_ay_key
1)
"uuid_one"
#返回集合所有value
127.0.0.1:6379> hvals hash_ay_key
1)
"12345"
#集合添加值
127.0.0.1:6379> hset hash_ay_key
"uuid_two"
"22222"
(
integer
) 1
#集合添加值
127.0.0.1:6379> hset hash_ay_key
"uuid_three"
"33333"
(
integer
) 1
#获得
key
为uuid_one的值
127.0.0.1:6379> hget hash_ay_key uuid_one
"12345"
#删除
key
为uuid_three的值
127.0.0.1:6379> hdel hash_ay_key uuid_three
(
integer
) 1
127.0.0.1:6379> hkeys hash_ay_key
1)
"uuid_one"
2)
"uuid_two"
#获得所有，包括
key
和value
127.0.0.1:6379> hgetall hash_ay_key
1)
"uuid_one"
2)
"12345"
3)
"uuid_two"
4)
"22222"
#更新
key
为uuid_one的值
127.0.0.1:6379> hset hash_ay_key uuid_one
"11111"
(
integer
) 0
127.0.0.1:6379> hset hash_ay_key
"uuid_one"
"11111"
(
integer
) 0
127.0.0.1:6379> hgetall hash_ay_key
1)
"uuid_one"
2)
"11111"
3)
"uuid_two"
4)
"22222"
例四：SortedSet集合的增删改查
SortedSet是有序的set集合
#sorted
set
添加值ay 排序值为 1
127.0.0.1:6379> zadd zset_ay_key 1
"ay"
(
integer
) 1
127.0.0.1:6379> zadd zset_ay_key 2
"al"
(
integer
) 1
127.0.0.1:6379> zadd zset_ay_key 3
"xy"
(
integer
) 1
127.0.0.1:6379> zadd zset_ay_key 4
"xl"
(
integer
) 1
#查询所有的值
127.0.0.1:6379> zrange zset_ay_key 0 -1
1)
"ay"
2)
"al"
3)
"xy"
4)
"xl"
#删除所有的值
127.0.0.1:6379> zrem zet_ay_key
"xl"
(
integer
) 0
127.0.0.1:6379> zrange zset_ay_key 0 -1
1)
"ay"
2)
"al"
3)
"xy"
4)
"xl"
