Easy SQL access to complex array structures in IMS databases

At the moment the IMS Universal JDBC Driver respectively the IMS DB Resource Adapters support only access to simple array structures based of fields in one datatype. Please enhance both the IMS Universal JDBC Driver and the IMS DB Resource Adapters to support access to complex array structures with repeating groups of fields that have different datatypes (array of structs).

Besides this the array access is at the moment in General very uncomfortable because the field names cannot be used to retrieve array values from a SQL result set. Please enhance these Array result sets such that array values can be accessed by providing their field names instead of column numbers. This simplifies especially the processing of complex arrays with a lot of different repeated fields a lot.

    It is our mission, within IMS, to deliver high quality code to our clients. Our goal is that this enhancement continues to help drive success for your company!

    I am excited to share with you that we have successfully delivered an enhancement that can help with the requested RFE ID 128416.

    This enhancement has been delivered via IMS service process:
    - IMS 14 APAR[PTF]: PH14139[UI64957] - http://www-01.ibm.com/support/docview.wss?crawler=1&uid=swg1PH14139
    - IMS 15 APAR[PTF]: PH14157[UI64958] - http://www-01.ibm.com/support/docview.wss?crawler=1&uid=swg1PH14157

    This APAR provides a number of enhancements for enabling ByteBuffers in the DLI and JDBC DB interfaces. Adding a new Interface for issuing ICAL, added enhanced support for Dynamic Arrays and ArrayResultSets.

    This allows the ease of accessing to Array datatype fields using the expandArrayResultSet property. The property will tell the IMS Universal JDBC driver to create an ArrayResultSet with the array elements as the actual fields in the ResultSet as opposed to having a Struct object that contains those elements as the only entry into that ResultSet.

    For detail information about the new interface, see the documentation or in the HOLD card section of the APAR.

    Please share your feedback with us as you implement this enhancement.

    Have a great day!

    Thank you for your interest in keeping IMS a vital and successful product. Software development has continuously evolved during IMS's lifetime, and so has IMS itself. We have kept pace with, adopted, and implemented many industry standard best practices within our organization, including Continuous Delivery, Design Thinking, and Agile.

    When choosing new features to add from the list of requirements in our backlog, we assess which will bring the most value to as many clients as possible and prioritize those.

    After reviewing this request for enhancement and assessing its potential value, our decision is to add this item to our backlog. Items in our backlog are expected to start working within the next 18 months. We reserve the right to re-prioritize our backlog items as new requests come in. This helps ensure that we are constantly focused on providing the best value to all of our clients.


    Have a great day!
