SELECT productno,
         productsubno,
         LISTAGG (productdesc, ',') WITHIN GROUP (ORDER BY productdesc)
    FROM TABLE_X
GROUP BY productno, productsubno

o/p :

1 2 laptop,desktop,hardisk

You can achieve output without commas by modifying
" LISTAGG (productdesc, ',') WITHIN GROUP (ORDER BY productdesc)"  TO
" LISTAGG (productdesc, '      ') WITHIN GROUP (ORDER BY productdesc)"

You can publish it as a csv by using

  SELECT productno||','||
         productsubno||','||
         LISTAGG (productdesc, ',') WITHIN GROUP (ORDER BY productdesc)
    FROM TABLE_X
GROUP BY productno, productsubno

1,2,laptop,desktop,hardisk

which query did you use? did you transcribe it accurately?

i.e. it is hard for use to know what that error relates to. Please copy/paste the EXACT query you used and the EXACT error message.
