    rpad(...,...,...)

    Hi All,

    Am trying to insert 50As if the column is null
    e.g

    select decode('','',rpad('',50,'A'),'') from dual


    Need help, above code is not working, any idea.

    Thanks in advance.

    You need the column name, compare:

    select decode(dummy,NULL,rpad(dummy,50,'A'),dummy) from dual;

    select decode(dummy,'X',rpad(dummy,50,'A'),dummy) from dual;

    Hi,
    Still not working,
    for example

    if dname is null then I need to add 5 As.

    select decode(dname,null,rpad(dname,5,'A') from dept;

    Thanks.

    Nvl(dname,'AAAAA') might be more intuitive.

    Nvl(dname,rpad('A',50,'A')) would save counting 50 of them. (Most probably wrongly if I were doing it).

    Is it "5", or "50"? Seems to be some confusion. if 50, then RPAD('A',50,'A') is indeed more robust.
