Extending HCL OneDB™Beyond standard relational database objects, HCL OneDB™ can be extended to handle specialized data types, access methods, routines, and other objects. HCL OneDB™ includes many built-in extensions that are fully integrated in the database server. HCL OneDB™ also provides DataBlade® modules, which are packages of extended database objects for a particular purpose and that are installed separately from the database server. Alternatively, you can create your own user-defined objects for HCL OneDB™.
HCL OneDB™ extensions and DataBlade® modulesThese topics describe how to use built-in database extensions and separately installed DataBlade® modules.
Spatial Data User's GuideThe HCL OneDB™ Spatial Data User's Guide contains information to assist you in using the HCL® OneDB® spatial extension. The HCL® OneDB® spatial extension adds custom data types and supporting routines to the server.

Shape type values

A shape type of 0 indicates a null shape with no geometric data for the shape.


Value	Shape type	Spatial data type
0	Null Shape	Empty ST_Geometry
1	Point	ST_Point
3	PolyLine	ST_MultiLineString
5	Polygon	ST_MultiPolygon
8	MultiPoint	ST_MultiPoint
9	PointZ	ST_Point with Z coordinates
10	PolyLineZ	ST_MultiLineString with Z coordinates
11	PointZM	ST_Point with Z coordinates and measures
13	PolyLineZM	ST_MultiLineString with Z coordinates and measures
15	PolygonZM	ST_MultiPolygon with Z coordinates and measures
18	MultiPointZM	ST_MultiPoint with Z coordinates and measures
19	PolygonZ	ST_MultiPolygon with Z coordinates
20	MultiPointZ	ST_MultiPoint with Z coordinates
21	PointM	ST_Point with measures
23	PolyLineM	ST_MultiLineString with measures
25	PolygonM	ST_MultiPolygon with measures
28	MultiPointM	ST_MultiPoint with measures

Shape types not specified above (2, 4, 6, and so on) are reserved for future use.

The ST_LineString and ST_Polygon Spatial data types do not have equivalent shape type values.
