create table #temp
partid     int,
maskid     int,
chemicalid int,
status  nvarchar(50)
insert into #temp
PartId    maskId
100       1000
200       1000
400       1500
600       1700
700       1700

Chemical Master Table
   PK                          fk
Chemicalmasterid  ChemicalId  PartId
  1                901         100
  2                902         200
  4                920         400
  6                909         600
  7                909         700

I need to write query do

update status='conflict chemical id' where
another parts related to same mask on temp table #temp have different checmicalid

for explain

#temp table have part 100 for masked 1000 and checmicalId 901
I will search on database

Are mask number 1000 have related parts ON Table parts have same maskId ?

yes it have

what other parts have same maskId ?

200 have maskid 1000

Are these parts as 200 have same chemicalid as exist on temp table #temp for same maskId ?

No then status will be 'conflict checmical id '

status conflict because maskId 1000 have chemicalId 901 on temp table #temp but on table parts
related parts have same maskId have different chemicalId as 902

What I have tried:

100 1000 901  conflict chemicalid
700 1700 909
400 1500 920
