【问题描述】*：
脚本语句如下：
select
detail.id as "id",
detail.work_days as "work_days",
detail.on_guard as "on_guard",
detail.no_guard as "no_guard",
detail.remark as "remark",
<if test="tkeys != null">
<foreach collection="tkeys" item="item">
detail.${item.key1} as #{item.key2},
</foreach>
</if>
detail.the_year_month
from
hr_attendance_detail detail
where detail.remark = #{remark}
该语句特殊点是在字段这边写了动态显示字段，初步怀疑是里面的 ? 没有进行替换

mybatis执行的时候，会报
Caused by: dm.jdbc.driver.DMException: 第 9 行, 第 47 列[?]附近出现错误:

该语句在mysql下是能正常执行，传入的参数也是正确的，跟踪调用链，是这边抛出的错误
