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™.

Locale-sensitive receive and send support functions

The SENDRECV (and mi_sendrecv) data type holds the internal structure of an opaque type. This internal structure can contain the following types of locale-sensitive data:

Character fields that can hold data in the code set of the client or database locale
This data includes single-byte (ASCII and non-ASCII) and multibyte character data.
Monetary, date, or time fields that hold a locale-specific representation of the data

The client application has no way of interpreting the fields of the internal structure because an opaque type is encapsulated.

The SENDRECV data type holds opaque-type data as it is transferred to and from the database server in this internal representation. You must write the receive and send support functions to interpret the locale-specific data within the SENDRECV structure.
