combine insert and update sql statement in JSP

I would like to insert data in a table a table called Reservations and Update the Books table to change the reserved row from "N" to "Y". It is a website that let the user reserve a book...if the book is reserved, the username is inserted in the reservations table and the status of the books will change to (REserved=='Y')...

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con=DriverManager.getConnection("Jdbc:Odbc:dBase","","");
stmt=con.createStatement( );

stmt.executeUpdate("INSERT INTO Reservations(ISBN,ReservedDate)"
+ "VALUES('"+isbn_n+"','"+date_d+"')" AND "UPDATE Books SET Reserved='Y' WHERE BookTitle='"+Book_Title+"'");


out.println("You have reserved the book successfully");


}

Select allOpen in new window

it is seems like the way i combine the two is wrong...could you pls help with to discover the mistake...

Thanks folks
