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.

where:
Argument | Description |
---|---|
demoHive |
Name of a hive where the operation is performed. |

Key name identifying a sorted set. |
Codeless Reference¶
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:
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.
The output will look as shown below after the Codeless logic runs.
