Help IBM prioritize your ideas and requests
The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.
Receive notification on the decision
Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.
Enhance SYSIBM.SQLFUNCTIONS to deliver meta data required by JCC (JDBC V4)
This is a quite old story. Back in 2015 this had already been addresses by COGNOS team IBM internally, but due to the possible impact to existing applications, it was refused to open an APAR for this issue. But RFE or DCR has not been opened by COGNOS so far. But now a 'real' customer is hitting this issue.
Actual customer cases are TS002132013, TS002126647, TS002297813 open against Cognos and Db2 and vice versa.
The original issue is lack of meta data being returned by stored procedure SYSIBM.SQLFUNCTIONS to fully support JDBC v4 standard of 'getFunctions' and 'getFunctionColumns' calls issued via jcc driver. The FUNCTION_TYPE value is still missing from the procedure an thus the function output!
