Extending HCL OneDB™Beyond standard relational database objects, HCL OneDB™ can be extended to handle specialized data types, access methods, routines, and other objects. Informix® includes many built-in extensions that are fully integrated in the database server. Informix® 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 Informix®.
HCL OneDB™ extensions and DataBlade® modulesThese topics describe how to use built-in database extensions and separately installed DataBlade® modules.
Database Extensions User's GuideThis publication 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, and SQL packages.The 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.
MQ Messaging (WMQ) messaging products provide an infrastructure for distributed, asynchronous communication of data in a distributed, heterogeneous environment. The WMQ message queue allows you to easily exchange information across platforms.
MQ messaging tablesYou use Virtual-Table Interface (VTI) access method to access WMQ queues using HCL® OneDB® table semantics.
Retrieve the queue elementUse the MQRead() function to retrieve the queue element.

Retrieve the queue element

Use the MQRead() function to retrieve the queue element.

For example:

BEGIN WORK;

EXECUTE FUNCTION MQRead('IDS.DEFAULT.SERVICE', 'IDS.DEFAULT.POLICY');
(expression)  PUT on queue with SQL INSERT
1 row(s) retrieved.
COMMIT WORK
