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.
Database Extensions User's GuideThe HCL OneDB™ Database Extensions User's Guide explains how to use the database extensions that come with HCL OneDB™: Large Object Locator, MQ messaging, binary data types, basic text search, node data type, HCL OneDB™ web feature service for Geospatial Data, and SQL packages.
Binary data typesThe binary18 and binaryvar data types allow you to store binary-encoded strings, which can be indexed for quick retrieval.

Binary data types

The binary18 and binaryvar data types allow you to store binary-encoded strings, which can be indexed for quick retrieval.

You can use string manipulation functions to validate the data types and bitwise operation functions that allow you to perform bitwise logical AND, OR, XOR comparisons or apply a bitwise logical NOT to a string.

Because the binary data types are unstructured types, they can store many different types of information, for example, IP addresses, MAC addresses, or device identification numbers from RFID tags. The binary data types can also store encrypted data in binary format, which saves disk space. Instead of storing an IP address like xxx.xxx.xxx.xxx as a CHAR(15) data type, you can store it as a binaryvar data type, which uses only 6 bytes.
