mybatis解决＜foreach＞标签不能超过1000的问题

    <select id="getProductInfoList" resultType="vo">
        select a.name 
        from A a
        where a.idin
        <foreach collection="ids" item="item" index="index" open="(" close=")" separator=",">
            #{item}
        </foreach>
    </select>

java.sql.SQLSyntaxErrorException: ORA-01795: maximum number of expressions in a list is 1000

    <select id="getProductInfoList" resultType="vo">
        select a.name 
        from A a
        where a.id in
         (select b.id from B b where b.id = #{billNo}  and DELETED = 0)
    </select>

	SELECT
		*
	FROM
		${tabNameMx} M
		WHERE
		M.CODE_ID IN
		<foreach collection="idList" index="index" open="(" close=")" item="id" separator=",">
			<if test="(index % 999) == 998"> NULL) OR M.CODE_ID IN(</if>#{id}
		</foreach>

CODE_ID IN('......','998',NULL ) OR M.CODE_ID IN('999',.....  NULL) OR M.CODE_ID IN('.....')

<select id="queryEnoByCapita">
  select t.custid,to_char(t.eno) as eno from T_E_ACCOUNT t where t.status !='2' and   t.custid in
 <trim suffixOverrides=" OR t.custid in()">
 <foreach collection="capita" item="custId" index="index" open="(" close=")">   
            <if test="index != 0">
                <choose>
                    <when test="index % 1000 == 999">) OR t.custid in (</when>
                    <otherwise>,</otherwise>
                </choose>
            </if>
     #{custId,jdbcType=VARCHAR} 
 </foreach>
 </trim>
</select>

<trim>标签suffixOverrides：去掉后缀匹配上的东西，本例中后缀如果是 OR t.custid in()与suffixOverrides的属性值刚好匹配，则去掉 OR t.custid in()
 
index 集合迭代的位置从0开始，为何需要<if test="index != 0">？如果没有，则sql是 t.cust in (,1,2..)会多一个逗号
 
没有999条数据的拼接SQL为：t.cust in (1,2..998) 
超过999条的数据拼接SQL为：t.cust in (1,2..998) or t.custid in（999,1000...1998） ...

collection  foreach循环的对象
item 集合中每一个元素或者该集合的对象,支持对象点属性的方式获取属性#{obj.filed} 或#{value}
index 循环的下标,从0开始 
open 表示以什么开始 
separator 每次进行迭代之间以什么符号作为分隔符 
close表示以什么结束

prefix  添加前缀
prefixOverrides  删除前缀
suffix  添加后缀
suffixOverrides  删除后缀
