i tried sort rows length(), cast(), substring_index(), failed.

query 1:

select item_name items  order  reverse(mid( reverse(mid(replace(replace(replace(replace(replace(item_name,',',''),' . ','. '),'r. ','g. '),'d. ','g. '),' g ','g. '),1,instr(replace(replace(replace(replace(item_name,' . ','. '),'r. ','g. '),'d. ','g. '),' g ','g. '), 'g. (')-1)), instr(reverse(mid(replace(replace(replace(replace(replace(item_name,',',''),' . ','. '),'r. ','g. '),'d. ','g. '),' g ','g. '),1,instr(replace(replace(replace(replace(item_name,' . ','. '),'r. ','g. '),'d. ','g. '),' g ','g. '), 'g.
