Oracle Spatial and Graph

 Oracle Spatial and Graph

Oracle Spatial and Graph is a feature in Oracle Database that provides advanced spatial and graph analytics capabilities. Oracle Spatial and Graph allows you to store and analyze spatial data, such as maps and geographic information, and graph data, such as social networks and complex relationships.

Here is an example of using Oracle Spatial and Graph to create a spatial index:

CREATE INDEX my_index ON my_table(my_geometry_column)

INDEXTYPE IS MDSYS.SPATIAL_INDEX;

This example creates a spatial index named "my_index" on the "my_geometry_column" column of the "my_table" table. The index is created using the MDSYS.SPATIAL_INDEX index type, which provides spatial indexing capabilities. Once the index is created, you can use spatial operators to query the data:

SELECT * FROM my_table WHERE SDO_WITHIN_DISTANCE(my_geometry_column, 'POINT(10 20)', 'distance=10') = 'TRUE';

This statement searches the "my_geometry_column" column of the "my_table" table for geometries that are within 10 units of the point (10, 20). If any matches are found, the statement returns the matching rows.
