1.将EXCEL中不需要的列删除
2.将EXCEL留下列的标题栏命名为数据库表的字段名
3.替换掉文件中的#REF!和#N/A等错误字符。
4.用达梦数据迁移工具将EXCEL文件导入到数据库中，创建新表。
在这里插入图片描述
5.将两张表的相关字段合并

merge into asset_rtu using asset_excel on asset_rtu.description=asset_excel.description when matched then update set

–重复的记录无法合并（共8条，如下可查出）
select * from asset_excel
where description in(select description from asset_excel
group by description having count(description)>1)
order by description;
