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

  1. Post an idea

  2. Upvote ideas that matter most to you

  3. 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.

Case TS000932532 - Load should be able to bypass a GENERATED-ALWAYS-from-variable column

Problem
A load on a table containing a certain type of GENERATED ALWAYS column fails with the very odd message "Unexpected load gencol section".
Research pointed out that LOAD cannot handle in any way a GENERATED ALWAYS column getting its information from a variable.
If the variable gets delivered by a function making sure a value is always returned even when the variable is not filled, makes no difference.
None of the LOAD modifiers helps while trying to bypass this restriction. So having the value in the file being handled for load also returns the "gencol" error.

The only option available is to drop the GENERATED ALWAYS-clause before the load and recreate it afterwards.

Possible solution 1:
A possible solution could be to add / extent a "File type modifiers for the load utility" option.

Possible solution 2:
In the case described the value of the GENERATED ALWAYS column comes from a function and should therefore not fail on the usage of variables.
