Generate script for filling table

Question

Hi all,
I've got table at test Oracle server table1 with columns ID, BTYPE, MYDESCRIPTION. Rows of this table have been inserted manually. Now my need is to write script for creating table (structure + data). I think about writing something like
CREATE TABLE table 1
AS
SELECT 1 AS ID, 'TYPE1' AS BTYPE, 'SOME TEXT' AS MYDESCRIPTION
UNION ALL
SELECT 2 AS ID, 'TYPE2' AS BTYPE, 'SOME TEXT 2' AS MYDESCRIPTION
But rows are too many to type... Could you please suggest some way of generating script for creating table at working server using existing table at test server? The problem is I don't have an access to working server.
Thanks ahead.

Use the view user_tab_cols
say
declare
cursor c1 is
select 'e_'||column_name ||' '||data_type||' ('||data_length||') ' col
  from user_tab_cols
  where table_name = 'DEPARTMENTS'
union
select 'd_'||column_name ||' '||data_type||' ('||data_length||') ' col
  from user_tab_cols
  where table_name = 'EMPLOYEES';
v1 varchar2(500);
begin
v1 := 'create table new_tabl (';
for i in c1 loop
v1 := v1||i.col||',';
end loop;
v1 := substr(v1,1,length(v1)-1);
dbms_output.put_line(v1||')');
end;
/i am using employees and departments table of hr schema.
now as both the tables have some column column so i have used e for employees and d for departments
just do one thing remove the length for date data type in o/p i dont know why it is not working.
this will give you structure for data use any sql stmt
