Description¶

This operation returns the number of items with a score a range between the specified min and max values.

Method¶

GET

Endpoint URL¶

Important

Make sure to replace xxxx in the domain name in the request specification below to the one assigned to your application.

https://xxxx.backendless.app/api/hive/[hive-name]/sorted set/[key]/count&  
   minScore=[minScore]&  
   minBound=[minBound]&  
   maxScore=[maxScore]&  
   maxBound=[maxBound]

where:

Argument	Description
`[hive-name]`	Name of a hive where the operation is performed.
`[key]`	Key name identifying a sorted set.
`[minScore]/[maxScore]`	Minimum and maximum value of the scores to identify the items to count. To control whether the specified score values are included or excluded from the range, use the `minBound`/`maxBound` parameters.
`[minBound]/[maxBound]`	Optional parameters. Available options are: `Include` - Includes value specified in the corresponding `minScore`/`maxScore` parameter into the range. `Exclude` - Excludes value specified in the corresponding `minScore`/`maxScore` parameter from the range. `Infinity` - Ignores the corresponding `minScore`/`maxScore` parameter and includes all consecutive score values that come before/after the defined score range. For example, if `minBound` is set to Infinity and `maxScore` is set to 5, the query will include all values with scores less than 5.

Request Headers¶

None.

Request Body¶

None.

Response Body¶

Number of items with a score and range between the specified min and max values.

Example¶

The example gets the count of items with scores between 1 and to 20. The minBound parameter is Include, as a result the score of 1 is included in the range. The maxBound parameter is set to Exclude, as a result, the value of 20 is excluded from the range.

curl --location --request DELETE "https://xxxx.backendless.app/api/hive/demoHive/sorted set/leaderboard/count?minScore=1&minBound=Include&maxScore=20&maxBound=Exclude"

where:

Argument	Description
`demoHive`	Name of a hive where the operation is performed.
`leaderboard`	Key name identifying a sorted set.

Codeless Reference¶

sorted_set_api_get_count_with_a_query

where:

Argument	Description
`hive name`	Name of a hive where the operation is performed.
`key name`	Key name identifying a sorted set.
`min/max score`	Specify the minimum and maximum score values to form a range. Refer to description above.
`min/max bound`	Parameters that control the presence of the first and last values in the range. Each parameter has three options: `Include` - Includes value specified in the corresponding `min score`/`max score` parameter into the range. `Exclude` - Excludes value specified in the corresponding `min score`/`max score` parameter from the range. `Infinity` - Ignores the corresponding `min score`/`max score` parameter and includes all consecutive score values that come before/after the defined score range. For example, if `min bound` is set to Infinity and `max score` is set to 5, the query will include all values with scores less than 5. These parameters default to `Include`.

Returns the number of items with a score and range between the specified min and max values.

Consider the following Sorted Set storage:
sorted_set_api_example_all_blocks

The example below retrieves the count of items with scores between 0 and to 5. Considering the sorted set (i.e. "players") presented above only two values are counted since "Bobby" has the score of 3 and "John" has the score of 5; These two values fall into the specified score range.
