How to get Part Id that have part level 0 and not have map from ?

I work on SQL server 2012 I face issue I can't get Parts that have map to

and not have map from for part level 0

so Firstly I get parts that have part level 0

then secondly

if part have code type to 1273200 then it must have code type from 974451

if part have code type to 194480 then it must have code type from 7320911

so I need to display

parts that have code type 1273200

for part level 0 and not have map from 974451

OR

parts that have code type 194480

for part level 0 and not have map from 7320911

sample code

  create table #codes  
(  
PartId int,  
CodeTypeId  int,  
Partlevel int  
)  
insert into #codes(PartId,CodeTypeId,Partlevel)  
values  
---this is correct----  
(1250,974451,0),  ---map from  
(1250,1273200,0), ---map to  
(1250,7320911,0), ---map from  
(1250,194480,0),  --map to  
------------------  
--where map from 974451 for part id 1900 for partlevel 0  
(1900,1273200,0),---map to  
(1900,7320911,0),---map from  
(1900,194480,0),--map to  
------------------  
(2200,974451,0),---map from  
(2200,1273200,0),---map to  
--where map from 7320911 for part id 2200 for partlevel 0  
(2200,194480,0),--map to  
-----------------  
(3400,974451,1),  --where map from 974451 for part id 3400 for partlevel 0 so if 1 it is wrong  
(3400,1273200,0), ---map to  
(3400,7320911,0), ---map from  
(3400,194480,0),  --map to  
------------------  
-----------------  
 --where map from 974451 for part id 3900 for partlevel 0 so if 1 then it is not exist   
(3900,1273200,0), ---map to  
(3900,1997801,0),   
(3900,7320911,0), ---map from  
(3900,194480,0),  --map to  
  
  
(5020,974451,1),   
(5020,1997801,1),  
(5020,7320911,1), --where map from 7320911 for part id 5020 for partlevel 0 if 1 then it is not exist  
(5020,194480,0),  --map to  
------------------  
  
------------------  
  
 ---map from 974451 not exist for part id 7050 but not care because I need only parts have partlevel 0  
(7050,1273200,1), ---map to  
(7050,7320911,1), ---map from  
(7050,194480,1),  --map to  
-----------------  
 ---map from 7320911 not exist for part id 8900 for partlevel 0 if part level 1 then not exist   
(8900,7320911,1), ---map from  
(8900,194480,0),  --map to  
-----------------  
  
 ---map from 7320911 not exist for part id 9200 for partlevel 0    
(9200,194480,0)  --map to  
-----------------  

Expected Result

    PartId CodeTypeId Partlevel  
1900 1273200 0  
2200 194480 0  
3400 1273200 0  
3900 1273200 0  
5020 194480 0  
8900 194480 0  
9200 194480 0

    Hi @ahmed salah ,

    Please refer below and check whether it is working:

    ;with cte as (  
        select *,ROW_NUMBER() over (order by partid) rn from #codes   
        where PartId=1250)  
    ,cte2 as (  
    	select partid,CodeTypeId,floor((rn- 1)/2)+1 as groupid  
    	from cte)  
     ,cte3 as (   
         select distinct  a.PartId,b.CodeTypeId,b.groupid from #codes a  
         cross apply (select CodeTypeId,groupid from cte2) b)  
     ,cte4 as (  
         select a.*,b.PartId PartId1,b.Partlevel from cte3 a  
         left join ( select * from #codes where partlevel=0) b  
         on a.PartId=b.PartId and a.CodeTypeId=b.CodeTypeId )  
     ,cte5 as (  
         select PartId,groupid from cte4  
         where PartId1 is null  
         group by PartId,groupid  
         having count(*)=1)  
     select distinct a.PartId,c.CodeTypeId,c.Partlevel   
     from cte5 a  
     inner join cte3 b on a.PartId=b.PartId and a.groupid=b.groupid  
     left join cte4 c on a.PartId=c.PartId and a.groupid=c.groupid  
     where PartId1 is not null  
     order by PartId  
    

    Output:

    PartId CodeTypeId Partlevel  
    1900 1273200 0  
    2200 194480 0  
    3400 1273200 0  
    3900 1273200 0  
    5020 194480 0  
    8900 194480 0  
    9200 194480 0  
    

    Best regards
    Melissa
