当有数据导出需求的时候
我们直接写sql语句就能实现
但是有时候mysql中存储的数值太大了,在excel里面会变成科学计数法,如果超过了64位的话,那么还会丢失精度
需要在sql语句中concat 拼接一个
例如这样的sql里的
concat(' ',a.ding_userid),
select a.id, a.username, a.nickname, a.phone, a.create_time, d.name as store_name, a.status, a.work_types, CASE a.work_types WHEN "2,4" THEN '育婴师,保姆' WHEN "1,2,4" THEN '母婴护理师,育婴师,保姆' WHEN "3,11" THEN '催乳,产康' WHEN "1,2" THEN '母婴护理师,育婴师' WHEN "1,4" THEN '母婴护理师,保姆' WHEN "1,2,3,4" THEN '母婴护理师,育婴师,催乳,保姆' ELSE e.desc END AS many_work, a.grade, concat(' ',a.ding_userid), a.organization_id, concat(' ',a.snow_id), b.name, c.name from mumway_admin a left join mumway_admin_department b on a.department_pid = b.id left join mumway_admin_department c on a.department_id = c.id left join mumway_store d on a.store_id = d.id left join mumway_masterneed e on e.id = a.work_types where a.in_status != 3 order by a.id desc limit 5000;
