Unpivot or pivot SQL

Question

I have some tables, only one row, but many columns, like this:
Name Null? Type
column1 NUMBER
column2 VARCHAR2(9)
column3 VARCHAR2(9)
column99 VARCHAR2(9)
I want a SQL to generate this kind of result:
Column1 : 1
Column2 : Oracle
Column3 : DB2
Column99 : SQL Server
This SQL could run in 8i,9i,10g and 11g.
Thanks,

In asktom you can search for a function called PRINT_TABLE. I have modified a little to use it as a table function.
drop type table_object
drop type column_object
drop function print_table
create type column_object as object(column_name varchar2(30), column_values varchar2(4000))
create type table_object as table of column_object
create or replace function print_table( p_query in varchar2 ) return table_object pipelined
is
    l_theCursor     integer default dbms_sql.open_cursor;
    l_columnValue   varchar2(4000);
    l_status        integer;
    l_descTbl       dbms_sql.desc_tab;
    l_colCnt        number;
begin
    execute immediate 'alter session set nls_date_format=''dd-mon-yyyy hh24:mi:ss'' ';
    dbms_sql.parse(  l_theCursor,  p_query, dbms_sql.native );
    dbms_sql.describe_columns( l_theCursor, l_colCnt, l_descTbl );
    for i in 1 .. l_colCnt loop
        dbms_sql.define_column(l_theCursor, i, l_columnValue, 4000);
    end loop;
    l_status := dbms_sql.execute(l_theCursor);
    while ( dbms_sql.fetch_rows(l_theCursor) > 0 ) loop
        for i in 1 .. l_colCnt loop
            dbms_sql.column_value ( l_theCursor, i, l_columnValue );
            pipe row (column_object(l_descTbl(i).col_name,l_columnValue));
        end loop;
    end loop;
    execute immediate 'alter session set nls_date_format=''dd-MON-rr'' ';
    return;
exception
    when others then
      execute immediate 'alter session set nls_date_format=''dd-MON-rr'' ';
      raise;
end;
show errSo this would work like this.
