用PrepareStatement对象在sql语句 的insert中怎样实现id的自增长，我的代码如下可是有错误 请指教 谢谢

create or replace trigger S_INTERVIEW_ID
before   insert   on   INTERVIEW_INFO
referencing   old   as   old   new   as   new   for   each   row
begin
new.INTERVIEW_ID=S_INTERVIEW_ID.nextval;
end;


        sql
                .append("insert into INTERVIEW_INFO ( INTERVIEW_ID,INTERVIEWEE_NAME, INTERVIEWEE_SEX,");
        sql
                .append("INTERVIEWEE_POSITION,GRADUATION_DATE, EDU_BACKGROUND, FOREIGN_LANG, FOREIGN_MEMO,");
        sql
                .append(" BUSTRIP_FLAG, BUSTRIP_TIME,DEPT_DEVELOP, OUTSOURCING_FLAG, LEAVE_REASON, BIRTH_YEAR,  ");
        sql
                .append("NATIVE_PLACE, BGFRIEND_FLAG,BGFRIEND_PLACE, DESAIRED_SALARY, BEFORE_SALARY, WORK_TIME, ");
        sql.append("COMPACT_STATUS, TECHNICAL_REVIEW,OVERALL_MERIT, FINAL_RESULT, JAPAN_LEVEL)");
        sql.append("values (S_INTERVIEW_ID.Nextval,？,？, ？, ？, ？, ？, ？, ？, ？, ？, ？, ？, ？,");
        sql.append("？, ？, ？, ？, ？, ？, ？, ？, ？, ？, ？)");
