Statistical Query Group And Sort

Demonstrates how to query a feature table for statistics grouping and sorting by different fields.

How it works

To query statistics from a feature table:

  1. Create and load a ServiceFeatureTable.
  2. Get the feature tables field names list with featureTable.getFields().
  3. Create StatisticDefinitions specifying the field to compute statistics on and the StatisticType to compute.
  4. Create StatisticType passing in the list of statistic definitions.
  5. To have the results grouped by fields, add the field names to the query parameters' groupByFieldNames collection.
  6. To have the results ordered by fields, create OrderBys, specifying the field name and SortOrder. Pass these OrderBys to the parameters' orderByFields collection.
  7. To execute the query, call featureTable.queryStatisticsAsync(queryParameters).
  8. Get the StatisticQueryResult. From this, you can get an iterator of StatisticRecords to loop through and display.
