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.
Spatial data typesHCL® OneDB® spatial data types are divided into two categories: the base geometry subclasses and the homogeneous collection subclasses.
Spatial data types with SPLYou can use stored procedure language (SPL) with spatial data types.

SPL has two restrictions that might be relevant to working with spatial data:

LVARCHAR variables in an SPL routine are restricted to 2K.
SPL does not support a global variable defined on a UDT or complex type.
