SQL & PL/SQL

Hi,

I'm juste learning how to create stored procedures and through sqldevelopper, I'd like to create a stored procedures which create a table  and import its value from a select statement; after I need to update the table by adding some columns.

The two queries looks like:

CREATE TABLE TBL_MEMBRES_CLEAN AS
SELECT IDM, SNAME, FNAME, DBIRTH, INF1, INF2, INF3, INF4
FROM tbl_membres;

alter table
   tbl_membres
add
   (
   SNAME_CLEAN tbl_membres.SNAME%TYPE,  
   FNAME_CLEAN tbl_membres.FNAME%TYPE,
   COL1 VARCHAR2,
   COL2 VARCHAR2,
   COL3 VARCHAR2,
   COL4 VARCHAR2
   );

Is it possible to make them by using only one procedure ?

Thanks in advance.
