一、查詢出分組對應的fid；

select * from T_BD_MATERIALGROUP_L where fname like '%000%'

二、找出對應的物料fnumber；

select a.fnumber from T_BD_MATERIAL a

left join (select fid,fname From T_BD_MATERIALGROUP_L ) t4 on a.FMATERIALGROUP=t4.fid

where t4.fname like '%000%' and FMATERIALGROUP=16416826

三、更新；

update a set a.FMATERIALGROUP=12258320 from T_BD_MATERIAL a

left join (select fid,fname From T_BD_MATERIALGROUP_L ) t4 on a.FMATERIALGROUP=t4.fid

where t4.fname like '%000%' and FMATERIALGROUP=16416826

物料表的分組前臺跟後臺不一樣
