Detailed Description

Queries can find statistics based on a geometry filter, or a SQL WHERE clause.

This QML type supports the following default properties. A default property may be declared inside another declared object without being assigned explicitly to a property.

See also FeatureTable.

Property Documentation

[default] geometry : Geometry

The input geometry used for a spatial filter.


groupByFieldNames : list<string>

The fields by which statistical query results will be grouped.


orderByFields : list<OrderBy>

The sort order of result.

Results can be sorted on one or more fields. Each OrderBy instance includes a field name and whether to sort by that field in ascending or descending order.

See also OrderBy.


spatialRelationship : Enums.SpatialRelationship

The spatial relationship to use when applying the geometry filter.

See also Enums.SpatialRelationship.


statisticDefinitions : list<StatisticDefinition>

The definition of statistics (input field, output name, statistic type) to include in a statistical query of a table.
