1.16 JSON and GeoJSON Support in Oracle Spatial
Spatial supports the use of JSON and GeoJSON objects to store, index, and manage geographic data that is in JSON (JavaScript Object Notation) format.
JSON support, introduced in Release 18.1, substantially expands the limited GeoJSON support available in the previous release, in that it supports a larger range of geometries, including 2D and 3D, solid, surface, and LRS geometries. While the Spatial GeoJSON-specific APIs are still supported, you are encouraged to use the more comprehensive JSON support.

1.16.1 JSON Support in Oracle Spatial
Spatial supports the use of JSON objects to store, index, and manage geographic data that is in JSON (JavaScript Object Notation) format.
You can convert any Oracle Spatial SDO_GEOMETRY object to a JSON geometry object, and geometry JSON object back to an SDO_GEOMETRY object.
JSON support in Spatial includes the following:
-
SDO_UTIL.TO_JSON converts an SDO_GEOMETRY object to a JSON object in CLOB format.
-
SDO_UTIL.TO_JSON_VARCHAR converts an SDO_GEOMETRY object to a JSON object in VARCHAR2 format.
-
SDO_UTIL.FROM_JSON converts a JSON object (in CLOB or VARCHAR2 format) to an SDO_GEOMETRY object. This function can also convert a GeoJSON object to an SDO_GEOMETRY object.
Example 1-3 JSON Support in Spatial
This example shows some operations using the JSON support in Oracle Spatial. The example creates a simple table with a JSON column and an SDO_GEOMETRY column, inserts some sample data, performs some simple queries, creates a spatial index, and performs a query using the SDO_WITHIN_DISTANCE operator.
The example uses the following JSON-related feature of Oracle Database, which is documented in Oracle Database JSON Developer's Guide:
-
The IS JSON Oracle SQL condition in a check constraint in the CREATE TABLE statement to ensure that a column contains JSON data
The example includes descriptive comments and the output of the SQL statements. (The output has been reformatted for readability.)
-- Some operations using JSON support in Spatial.
-- Create a table with 3 columns: one JSONC (JSON CLOB), one JSONV (JSON VARCHAR2),
-- and one SDO_GEOMETRY.

1.16.2 GeoJSON Support in Oracle Spatial
Oracle Spatial supports the use of GeoJSON objects to store, index, and manage geographic data that is in JSON (JavaScript Object Notation) format.
You can convert Spatial SDO_GEOMETRY objects to GeoJSON objects, and GeoJSON objects to SDO_GEOMETRY objects. You can use spatial operators, functions, and a special SDO_GEOMETRY method to work with GeoJSON data.
GeoJSON support in Spatial includes the following:
-
SDO_UTIL.TO_GEOJSON function to convert an SDO_GEOMETRY object to a GeoJSON object..
-
SDO_UTIL.FROM_GEOJSON function to convert a GeoJSON object to an SDO_GEOMETRY object.
-
Get_GeoJson method (member function) of the SDO_GEOMETRY type (see SDO_GEOMETRY Methods for an explanation and an example).
Example 1-4 GeoJSON Support in Spatial
This example shows some operations using the GeoJSON support in Spatial. The example creates a simple table with a GeoJSON column and an SDO_GEOMETRY column, inserts some sample data, performs some simple queries, creates a spatial index, and performs a query using the SDO_WITHIN_DISTANCE operator.
The example uses the following JSON-related features of Oracle Database, which are documented in Oracle Database JSON Developer's Guide:
-
The JSON_VALUE Oracle SQL function with
RETURNING SDO_GEOMETRYto return SDO_GEOMETRY objects reflecting GeoJSON objects -
The IS JSON Oracle SQL condition in a check constraint in the CREATE TABLE statement to ensure that a column contains JSON data
The example includes descriptive comments and the output of the SQL statements. (The output has been reformatted for readability.)
