But there is no problem after removing a placeholder

Then it turned regular after he SQL statements to the following
String SQL="insert into account (account_id, recommender_id, login_name login_password, status, create_date, pause_date, close_date, real_name, idcard_no, birthdate, and gender) values (1 account_seq nextval,? ,? ,? , '0', sysdate, null, null,? ,? The to_date (? , '- dd yyyy - mm),?) ";
