The specification of a Feature Source Query. Encapsulates the definition of a Feature Source Query A standard FDO feature source query A FDO aggregate query A SQL query executed through FDO Specifies common properties for all query types Link to the feature source. Provider capabilities should determine what optional elements in the rest of this schema are applicable If specified, declares information about the designated geometry for purposes of rendering/stylization and spatial contexts If specified, declares which properties will be designated as geometries Specifies common properties for standard select and aggregate queries Specifies the feature class to query from Specifies the FDO filter for this query Specifies the list of properties to include in the query. If this element is not specified, all properties are included Specifies the list of computed properties to include in the query. Specifies the list of properties to order the select query by. The underlying provider must support select ordering Specifies the ordering direction Specifies parameters for a standard Feature Source Query Specifies parameters for an Aggregate Query Specifies whether to restrict the values returned by a select operation to be unique Specifies the list of properties to group the aggregate query by Specifies the grouping filter for the aggregate query Specifies parameters for a SQL query Specifies the SQL SELECT query string. This string may contain parameter references. The SQL is a dialect specific to the underlying provider Specifies a collection of class properties Specifies the FDO class property name Specifies a collection of computed properties Specifies the computed property Specifies a computed property Specifies the alias for this computed property Specifies the FDO expression for this computed property Specifies geometric and spatial context information for the query Specifies the designated geometry property or column. A bitmask value representing the applicable geometry types This would return AWKT representing extents e.g. polygon, polyline or circle etc. Specifies select ordering direction
