How to call DDL statements from pl/sql?..

Answer / pavan_1981

One can call DDL statements like CREATE, DROP, TRUNCATE,
etc. from PL/SQL by using the "EXECUTE IMMEDATE" statement.
Users running Oracle versions below 8i can look at the
DBMS_SQL package .
begin
EXECUTE IMMEDIATE 'CREATE TABLE X(A DATE)';
end;
NOTE: The DDL statement in quotes should not be terminated
with a semicolon.

Another way is One can also use the older DBMS_SQL package
(V2.1 and above) to execute dynamic statements. Look at
these examples:
CREATE OR REPLACE PROCEDURE DYNSQL AS
cur integer;
rc integer;
BEGIN
cur := DBMS_SQL.OPEN_CURSOR;
DBMS_SQL.PARSE(cur, 'CREATE TABLE X (Y DATE)',
DBMS_SQL.NATIVE);
rc := DBMS_SQL.EXECUTE(cur);
DBMS_SQL.CLOSE_CURSOR(cur);
END;
