Detailed Description

A set of output parameters for aggregateUnique(const AggregateUniqueRequest&) const.

Returns all the unique values from a particular column (specified by columnName) of a particular table (specified by tableName). If columnName is a numeric column the values will be in binaryEncodedResponse. Otherwise if columnName is a string column the values will be in jsonEncodedResponse. offset and limit are used to page through the results if there are large numbers of unique values. To get the first 10 unique values sorted in descending order options would be::

{"limit":"10","sort_order":"descending"}.

The response is returned as a dynamic schema. For details see: dynamic schemas documentation. If the 'result_table' option is provided then the results are stored in a table with the name given in the option and the results are not returned in the response.
