ibatis 循环迭代

一、指定参数类型为List
<!--iterate不要property属性 -->
<delete id="delStudybook" parameterClass="java.util.List">
 delete FROM STUDYBOOK WHERE ID IN
 <iterate conjunction="," open="(" close=")">
  #bookList[]#
 </iterate>
</delete>

二、不制定参数
<!--iterate不要property属性 传入的参数为数组-->
<select id="checkAccount_count" resultClass="java.lang.Integer">
 select count(*) from dbms_bankAccount b where 1=1 and b.accountno in
 <iterate open="(" close=")" conjunction=",">
  #[]#
   </iterate>
</select>

三、必须要property
<update id="updateUsersIterate" parameterClass="java.util.Map">
 update users set user_name=#userInfo.user_name# where user_id in
 <iterate property="list" conjunction="," open="(" close=")">
  #list[]#
 </iterate>
</update>

<select id="sql_test" parameterclass="myPramBean" resultclass="myResult">
         select *from tablewhere name in
        <iterate property="ids" conjunction="," close=")" open="(" />
        #ids[]#
        </iterate>
       and code=#code#
</select>
