Redis簡單增刪改查例子
例一：字符串的增刪改查
#增加一個
key
為ay_key的值
127.0.0.1:6379>
set
ay_key
"ay"
OK
#查詢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名稱
127.0.0.1:6379> rename ay_key new_ay_key
OK
127.0.0.1:6379> keys *
1)
"new_ay_key"
#刪除ay_key
127.0.0.1:6379> del ay_key
(
integer
) 0
#查詢是否存在ay_key 0
127.0.0.1:6379> exists ay_key
(
integer
) 0
例二：Set集合的增刪改查
#刪除當前選擇數據庫中的所有
key
127.0.0.1:6379> flushdb
OK
#生成
set
集合，添加4個數據
127.0.0.1:6379> sadd set_ay_key
"ay"
"al"
"xy"
"xl"
(
integer
) 4
#查詢
set
里面所有值
127.0.0.1:6379> smembers set_ay_key
1)
"xy"
2)
"al"
3)
"ay"
4)
"xl"
#刪除value為
"xl"
, 返回 1 如果沒有返回 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為
"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為
"xl"
添加不進去，但也不報錯，
set
是不允許重復的
127.0.0.1:6379> sadd set_ay_key
"xl"
(
integer
) 0
#不多解釋
127.0.0.1:6379> sadd set_ay_key
"xl"
(
integer
) 0
#不多解釋
127.0.0.1:6379> sadd set_ay_key
"xl"
(
integer
) 0
例三：List集合的增刪改查
#添加
key
為list_ay_key的list集合
127.0.0.1:6379> lpush list_ay_key
"ay"
"al"
"xy"
"xl"
(
integer
) 4
#查詢
key
為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頭部添加元素
127.0.0.1:6379> lpush list_ay_key
"first"
(
integer
) 6
#查詢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
為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"
#刪除
index
為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(類似
Java)的增刪改查
127.0.0.1:6379> flushdb
OK
#生成hash集合，並添加
key
為uuid_one value 為
"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
#獲得
key
為uuid_one的值
127.0.0.1:6379> hget hash_ay_key uuid_one
"12345"
#刪除
key
為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"
#獲得所有，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
為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集合的增刪改查
SortedSet是有序的set集合
#sorted
set
添加值ay 排序值為 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
#查詢所有的值
127.0.0.1:6379> zrange zset_ay_key 0 -1
1)
"ay"
2)
"al"
3)
"xy"
4)
"xl"
#刪除所有的值
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"
