We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:
Post your ideas
Post ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,
Post an idea
Upvote ideas that matter most to you
Get feedback from the IBM team to refine your idea
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.
IBM Data Server .Net Provider Support For Informix Types TEXT, BYTE and BOOLEAN
We are in the process of moving from .Net Framework to .Net Core. We currently use the Informix Client SDK ADO.Net drivers to access Informix databases using ADO.Net.
When we tried to migrate to the IBM Data Server Driver (IBM.Data.DB2.dll) we found that calling stored procedures worked except for some types (TEXT, BYTE and BOOLEAN). We contacted IBM and were told to use a workaround to call the stored procedures using TEXT and BYTE types, however this workaround does not follow the best practices set down by Microsoft for calling stored procedures from ADO.Net code. Also due to the generic way our products deal with different database providers, the workaround is not going to work for us.
Workaround suggested was to call the stored procedure using:
We've been given no response to the question about the BOOLEAN type.
After many weeks of communication about the issue we were told to either wait an unknown period of time for the new "native" Informix .NET Core provider or raise an RFE here. We are pursuing both options at the moment as this is blocking several projects.
If neither of these give a satisfactory result then we will need consider other options, including moving all our Informix customers to another database provider.
Example to replicate the issue (example for TEXT, but BYTE has the same behaviour) (please note the code below is purely test code to show the issue, it is not production code.)
