   g:=priceWorx.frcPriceListItemGroups('020','221');
   d:=priceworx.frcCustomerDiscounts('020','221',cuno);
  loop

    fetch d into comno,cpls,cuno,cpgs,stdt,tdat,qanp,disc,src;
    --dbms_output.put(chr(9)||cpgs);
    sQ:='Update saap.CustomersPriceGroups set "'|| trim(cpgs)||'"=:disc '
       || ' Where cuno=:cuno';
    execute immediate sQ using disc,cuno; 
    commit;
    dbms_output.put_line( sQ );
    dbms_output.put_line( chr(9)||'Parameters:   disc='|| disc||' cuno='||cuno);
    exit when g%notfound;
  end loop;
  close g;
  close d;
end loop;

推荐答案
