    transpose columns into rows

    Hi ,

    I have to transpose columns into rows and Iam using the follg SQL

    select substr(x,begin,end-begin)
    from (select pos+1 begin,nvl(lead(pos) over (order by pos),length(x)+1) end
    from (select instr(x,',',1,rownum) pos
    from dba_objects)
    where rownum <= length(x)-length(replace(x,','))+1
    );

    Here x is a database function which has a value
    of '10,20,30,40'

    This function takes a lot of time to execute so can i use this function
    only once in the sql clause and substitute all further occurences of the function with it's value ?
    Internally I would like to substitue x with it's value since the string can be of any value
