StringBuffer pagingSelect = new StringBuffer(100);
pagingSelect.append("select * from ( select row_.*, rownum rownum_ from ( ");
pagingSelect.append(sql);
pagingSelect.append(" ) row_ where rownum <= " + endRow + ") where rownum_ > " + startRow);
startRow 是记录开始处
endRow 是记录结束处
举例来说：
从第11条到第20条
select * from (
select row_.*, rownum rownum_ from (
select person_id, chn_name, chn_firstname_py from t_pbase_info
) row_ where rownum <=20
) where rownum_ >=11
