plsql questions

1  can one call DDL statement from PL/SQL?
one can call DDL statements like Create,DROP,Truncate ,etc from PL/SQL by using the "EXECUTE IMMEDIATE" statement examples
DECLARE
  var VARCHAR2(100);
BEGIN
  var := 'CREATE TABLE temp1(col1 NUMBER(2))';
  EXECUTE IMMEDIATE var;
END;

NOTE: The DDL statement in quotes should not be terminated with a semicolon.

Users running Oracle versions below Oracle 8i can look at the DBMS_SQL package (see FAQ about Dynamic SQL).
