insert語句中包含子查詢問題
Ibatis中的Insert語句,將values採用select代替
<insert id="insertFaqContinue">
INSERT INTO FAQ (
<dynamic prepend="">
<isNotNull prepend="," property="topicID"> topicID </isNotNull>
<isNotNull prepend="," property="listID"> listID </isNotNull>
<isNotNull prepend="," property="topicID"> faqfloor </isNotNull>
</dynamic>
)
SELECT
<dynamic prepend="">
<isNotNull prepend="," property="topicID"> #topicID# </isNotNull>
<isNotNull prepend="," property="listID"> #listID# </isNotNull>
<isNotNull prepend="," property="title"> #title# </isNotNull>
<isNotNull prepend="," property="topicID"> (SELECT count(faqID)+1 FROM FAQ WHERE topicID = #topicID#) </isNotNull>
</dynamic>
<selectKey resultClass="int" keyProperty="faqID" >
SELECT @@IDENTITY AS faqID
</selectKey>
</insert>
分析:整體結構爲Insert into select 語句,select 語句中包含子查詢
<insert id="insertSubjectRelDemand" parameterClass="subjectreldemand">
insert into dsp_subject_reldemand (no,subject_no,demand_no,version)
select dsp_subject_reldemand_seq.nextval,#subject_no#,#demand_no#,(select version from dsp_subject where no = #subject_no#) from dual
</insert>
<!-- 插入一條歷史編輯內容 -->
<insert id="insertSubjectHistory" parameterClass="subjectHistory">
insert into dsp_hstry (sub_no,editer_no,edit_date,descr,sqls,caliber,clasy,version,edit_des)
(select no,cre_no,edit_date,descr,sqls,caliber,clasy,version,cre_des as edit_des from dsp_subject where no = #no#)
</insert>
