Create the table into the trigger using pl sql

To create table into the trigger using pl/sql you can try following code in SQL query editor or in stored procedure.

Create or replace trigger b_br after delete on EMP
declare
n integer;
PRAGMA AUTONOMOUS_TRANSACTION;
begin
dbms_output.put_line('Table Creation in process..');
execute immediate 'create table b_t(b varchar2(10))';
dbms_output.put_line('Table Created..');
end;

Delete from EMP;


Same way you can add more columns in tables with different data types.
