数据库是MySQL数据库，我想把我查出来的数据里面包含一二三，我想把一二三转换成数字的一二三如何实现。

SELECT distinct 

a.department AS 部门,

b.dealings_abbreviation AS 供应商,

a.business_manager_name AS 负责人,

a.consignment_date AS 发货日期,

a.weight AS 重量

FROM

bm_shipment_quantity a left join bd_current_unit_alias b on a.supplier=b.id 

group by a.department,b.dealings_abbreviation,a.consignment_date

ORDER BY find_in_set('a.department','1,2,3') ASC

主要是想把业务部排个序，现在的这个写法在页面上显示的是业务三二一这么个顺序
