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™.
Creating extensionsYou can create user-defined data types, routines, access methods, and other database objects to suit your needs. You can use application programming interfaces to write user-defined routines and applications that access data in HCL OneDB™ databases.
User-Defined Routines and Data Types Developer's GuideThe HCL OneDB™ User-Defined Routines and Data Types Developer's Guide describes how to define new data types and enable user-defined routines (UDRs) to extend HCL OneDB™.

The IMPEXPBIN data type

The IMPEXPBIN data type

SQL statements support an internal data type called IMPEXPBIN to hold the external binary representation of an opaque data type for a bulk copy. The IMPEXPBIN data type allows for any possible change in the size of the data when it is converted between the two representations. The importbinary and exportbinary support functions serve as cast functions between the IMPEXPBIN and opaque data type.
