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
