<sql id="pageS">
select c.* from (

select b.* from

(select @rownum :=@rownum + 1 AS rm,a.* from
(SELECT @rownum := 0) r,

(

</sql>

<sql id="pageE">
) a ) b where b.rm <= #{page}) c where c.rm >= #{page}

</sql>

oracle:

SELECT *
FROM (SELECT M.*, ROWNUM RN
FROM (
select ques_name,ques_type,ques_options,ques_score,ques_serial,QUES_ID,QUES_ANSWER,QUES_EXPLAIN
from q_question_tab
where ques_id in (SELECT ques_id FROM q_paper_question where paper_id=#{paperId})
and ques_type=#{ques.quesType} order by ques_serial
) M
WHERE ROWNUM <= #{page}) z
WHERE RN >= #{page}

mysql:

<include refid="pageS" />

select ques_name,ques_type,ques_options,ques_score,ques_serial,QUES_ID,QUES_ANSWER,QUES_EXPLAIN
from q_question_tab
where ques_id in (SELECT ques_id FROM q_paper_question where paper_id=#{paperId})
and ques_type=#{ques.quesType} order by ques_serial

<include refid="pageE" />
