Detailed Description
A set of parameters for GPUdb::filterByRadiusGeometry.
Calculates which geospatial geometry objects from a table intersect a circle with the given radius and center point (i.e. circular NAI). The operation is synchronous, meaning that a response will not be returned until all the objects are fully available. The response payload provides the count of the resulting set. A new resultant set (view) which satisfies the input circular NAI restriction specification is also created if a viewName is passed in as part of the request.

◆ FilterByRadiusGeometryRequest() [2/2]
| inline |
Constructs a FilterByRadiusGeometryRequest object with the specified parameters.
| [in] | tableName_ | Name of the table on which the filter by radius operation will be performed, in [schema_name.]table_name format, using standard name resolution rules. Must be an existing table. |
| [in] | viewName_ | If provided, then this will be the name of the view containing the results, in [schema_name.]view_name format, using standard name resolution rules and meeting table naming criteria. Must not be an already existing table or view. The default value is ”. |
| [in] | columnName_ | Name of the geospatial geometry column to be filtered. |
| [in] | xCenter_ | Value of the longitude of the center. Must be within [-180.0, 180.0]. The minimum allowed value is -180. The maximum allowed value is 180. |
| [in] | yCenter_ | Value of the latitude of the center. Must be within [-90.0, 90.0]. The minimum allowed value is -90. The maximum allowed value is 90. |
| [in] | radius_ | The radius of the circle within which the search will be performed. Must be a non-zero positive value. It is in meters; so, for example, a value of ‘42000’ means 42 km. The minimum allowed value is 0. The maximum allowed value is MAX_INT. |
| [in] | options_ | Optional parameters.

Member Data Documentation
◆ columnName
| std::string gpudb::FilterByRadiusGeometryRequest::columnName |
Name of the geospatial geometry column to be filtered.
Definition at line 154 of file filter_by_radius_geometry.h.
◆ options
| std::map<std::string, std::string> gpudb::FilterByRadiusGeometryRequest::options |
Optional parameters.
- filter_by_radius_geometry_create_temp_table: If true, a unique temporary table name will be generated in the sys_temp schema and used in place of viewName. This is always allowed even if the caller does not have permission to create tables. The generated name is returned in qualified_view_name. Supported values:The default value is filter_by_radius_geometry_false.
- filter_by_radius_geometry_collection_name: [DEPRECATED–please specify the containing schema for the view as part of viewName and use GPUdb::createSchema to create the schema if non-existent] Name of a schema for the newly created view. If the schema provided is non-existent, it will be automatically created.
The default value is an empty map.

◆ radius
| double gpudb::FilterByRadiusGeometryRequest::radius |

| std::string gpudb::FilterByRadiusGeometryRequest::viewName |
If provided, then this will be the name of the view containing the results, in [ schema_name. ]view_name format, using standard name resolution rules and meeting table naming criteria.
Must not be an already existing table or view. The default value is ”.
