oracle中 数据不能填null，数据操作时必须指定数据类型。否则报无效数据111 的错误
字符串类型的用

如果po中的参数类型是double 那么请使用
jdbcType=NUMERIC

批量删除：

方法：
void deleteBatch(@Param("list") List<InvDistributionResultPO> invDistributionResultList);

mapper.xml中的sql:
 <delete id="deleteBatch">
        delete from INV_DISTRIBUTION_RESULT A
        where exists
        (
        select 1 from(
        <foreach collection="list" item="item" index="index" separator="union all">
            select B.* from INV_DISTRIBUTION_RESULT B where 1=1 and
            B.TASK_MASTER_ID = #{item.taskMasterId,jdbcType=VARCHAR} AND
            B.TASK_CHILDREN_ID= #{item.taskChildrenId,jdbcType=VARCHAR} AND
            B.TASK_RESULT_ID= #{item.taskResultId,jdbcType=VARCHAR}
        </foreach>
        )S where A.ID=S.ID
        )
    </delete>

批量添加：

方法：
void insertBatch(@Param("list") List<InvDistributionResultPO> invDistributionResultList);
mapper.xml中的sql
<insert id="insertBatch">
INSERT INTO INV_DISTRIBUTION_RESULT
        (
        <include refid="Base_Column_List"/>
        )

        <foreach collection="list" index="index" item="item" separator="union">
            select
            #{item.id,jdbcType=VARCHAR},
            #{item.taskMasterId,jdbcType=VARCHAR},
            #{item.taskChildrenId,jdbcType=VARCHAR},
            #{item.taskResultId,jdbcType=VARCHAR},
            #{item.sourceTaskId,jdbcType=VARCHAR},
            #{item.queryAvailableId,jdbcType=VARCHAR}
            from dual
        </foreach>
    </insert>
