oracle在mybatis的批量更新操作

Integer updateLineSequence(@Param("list")List<LoadingPlanDVO> loadingPlanDList,
                           @Param("ownerID") String ownerID,
                           @Param("projectCode") String projectCode,
                           @Param("fixroute")String fixroute);

<update id="updateLineSequence" parameterType="java.util.List">
    <!-- 使用PL/SQL块执行批量更新 -->
        begin
        <foreach collection="list" item="item" separator=";">
            UPDATE linepoint l
            SET l.serialnumber = #{item.loadingSeq}
            WHERE l.OWNERID = #{ownerID}
            AND l.PROJECTCODE = #{projectCode}
            AND l.linecode = #{fixroute}
            AND l.pointcode = #{item.unloadingPlace}
        </foreach>
        ; -- 最后一个语句的分号，确保PL/SQL块正确结束
        end;
</update>
