string Mysql

Mysql = "CREATE TABLE Trainees "&

		+"(emp_id integer not null,"&

		+"emp_fname char(10) not null, "&

		+"emp_lname char(20) not null)"

EXECUTE IMMEDIATE :Mysql ;

string Mysql

Mysql="INSERT INTO department Values (1234,"&

       +"'Purchasing',1234)"

EXECUTE IMMEDIATE :Mysql USING My_trans ;
