My be you can try with and an SQL
create directory root as 'C:\';
declare
    vclob clob := empty_clob();
begin
    with mydata as
        select
            l || 'a' data1
        ,   l || 'b' data2
        ,   l || 'c' data3   
        ,   row_number() over(order by l)       curr
        ,   (row_number() over(order by l)) - 1 prev
        from
            ta
    select
        replace(ltrim(max(sys_connect_by_path(data1 || ',' || data2 || ',' || data2,':')), ':'), ':', chr(13))
    into
        vclob
    from
        mydata
    start with
        curr = 1
    connect by
    prior curr = prev;
    dbms_advisor.create_file(buffer     =>  vclob
                            ,location   =>  'ROOT'
                            ,filename   =>  'mycsv.csv'
end;
