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.

Add function LISTAGG like DB2 and Oracle

Every query which need to group by and concat few columns is impossible with informix.

For example for this SQL :

select t.tabname, c.constrname

,k.checktext, k.seqno

from sysconstraints c, systables t , outer syschecks k

where t.tabname = 'mytable'

and c.tabid = t.tabid

and c.constrtype in ('C','U','P')

and k.constrid = c.constrid

and type ='T'

order by 1,2,k.seqno

To join the checktext column into a single row is very painful or viable only with few programming code

    Other examples:

    SELECT city, LISTAGG(DISTINCT email,';') email_list
    FROM sales.customers
    GROUP BY city;

    SELECT deptno, LISTAGG(ename, ',') WITHIN GROUP (ORDER BY ename) AS employees
    FROM emp
    GROUP BY deptno;

    deptno employees
    ---------- --------------------------------------------------

    Also SQL Server has this function implemented as STRING_AGG
