Shape the future of IBM!

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,

  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.

We'd like a way to ALTER INLINE Scalar Functions

As noted in our 55126.379.000 PMR.... ‎

We recently encountered an issue when the need arose to change an inline UDF that has dependent objects (i.e. stored procedures). We ‎
found we cannot simply ALTER the UDF as we do when changing a stored procedure. Instead, we are required to drop dependent objects, redeploy the UDF and then recreate the dependent objects... including issuing grants. ‎

We did find that a non-inline function can be altered so, an option was to do a one-time conversion of the ‎function to a non-inline so that it could be altered in the future but, this still required the one-time drop of ‎dependent objects.‎
‎ ‎
So, short of converting all our functions to non-inline, so that we can subsequently do ALTERs on them, we'd like there to be a way to enhance UDFs WITHOUT dropping dependent objects and rebuilding everything that's dependent on them.‎
‎
This apparent restriction makes enhancing existing INLINE functions risky and time consuming.‎
