Redis data type operation (v)--sorted Set

1. Zadd

Format: Zadd ' name ' {num} ' value '

Add value to the sorted set named name. Num is the ordinal value of the element, and if the added num already exists, it does not overwrite the original value, and there will be two different values for the same num. However, a new num value can be given to a value that already exists.

2. Zrange

Format: Zrange ' name ' {NUM1} {num2} [Withscores]

Get the element named name of sorted set inside {NUM1} to {num2} subscript. The withscores will output the sequence number.

3. Zrangebyscore

Format: Zrangebyscore ' name ' {NUM1} {num2} [Withscores]

Get the element named name of the sorted set inside {NUM1} to {num2} sequence number (not subscript). The withscores will output the sequence number.

4. Zrem

Format: Zrem ' name ' ' value '

The value is removed from the sorted set named name.

5. Zincrby

Format: zincrby±{num} ' name ' ' value '

Let the order number of value increment by num, and if value does not exist, add value to sorted set with NUM for the order number. If NUM is negative, it is reduced.

6. Zrank

Format: Zrank ' name ' ' value '

Sorts the sorted set named name first in ascending order, and then returns the subscript for the sorted value.

7. Zrevrank

Format: Zrevrank ' name ' ' value '

Sorts the sorted set named name first in descending order, and then returns the subscript for the sorted value.

8. Zcount

Format: Zcount ' name ' {NUM1} {num2}

Gets the number of elements in the sorted set named name {NUM1} to {num2} sequence number (not subscript).

9. Zcard

Format: Zcard ' name '

Returns the number of elements in the sorted set named name.

Ten. Zremrangebyrank

Format: Zremrangebyrank ' name ' {NUM1} {num2} [Withscores]

Sort the sorted set named name first in ascending order, and then remove the value of the subscript {NUM1} to {num2}.
