Removing comma in a string - response (3) by Raja_KT

You have not explained with other columns. Let me assume that you can try thus: select oreplace (col1,',','')||oreplace (col2,',','')||oreplace (col3,',','') from table1.
For space use ||''|| say like select oreplace (col1,',','')||''||.....
If you want to append with text then select  'collect stats on '
Cheers,
