Question

I have one mastertable id Accessories CarColor variant values ( 1 863,862 6 2 5) etc (all id’s are going in my mastertable ) and 5 other table like car color,variant etc which has values

---

id   color
5    red
6    blue
3    green

I need value from each child tables whose id = mastertable.id
like

SqlCommand sqlCommand = new SqlCommand(" select * from cartable where carcolor.id = mastertable.carcolor ") ; 
SqlCommand sqlCommand = new SqlCommand(" select * from varianttable where variant.id = mastertable.variant ")  ; 
SqlCommand sqlCommand = new SqlCommand ("select * from accessoriestable where accessories.id = mastertable.accessories ") ;// 

my question is how can i join all 5 select statements together
or any better solution for this ?

Answer 1

I guess you need this?

select * from mastertable
left join carcolortable on mastertable.carcolor=carcolortable.id
left join varianttable on mastertable.variant=varianttable.id
left join accessoriestable on mastertable.accessories=accessoriestable.id

If as you’ve described in the comment mastertable.carcolor (and others) contains a comma separated list of Id‘s in varchar then it should be:

select * from mastertable
left join carcolortable on 
        ( ','+mastertable.carcolor+',' 
          LIKE 
          '%,'+CAST(carcolortable.id as varchar(100))+',%'
         )
left join varianttable on 
        ( ','+mastertable.variant+',' 
          LIKE 
          '%,'+CAST(varianttable.id as varchar(100))+',%'
         )

left join accessoriestable on 
        ( ','+mastertable.accessories+',' 
          LIKE 
          '%,'+CAST(accessoriestable.id as varchar(100))+',%'
         )
