Question

I want to create cartesian product sql query.But,I'm getting the error.Where I wrong?

alter table #Personel
(
Ad varchar(100)
)

alter table #Masa
(
 MasaAdi varchar(100)
)

insert into #Personel values('deneme1'),('deneme2'),('deneme3')
insert into #Masa values('Masa1'),('masa2'),('masa3')
select Ad,MasaAdi from
(
   select ROW_NUMBER() over(partition by MasaAdi order by ID,Ad ) as Sira
      ,ID,Ad,MasaAdi
   from (
   select newid() as ID,Ad,MasaAdi from #Personel
   left outer join #Masa on 1=1
   ) t
) t2 where Sira = 1 order by Ad
Was it helpful?

Solution

On SQL Server you can write

select Ad,MasaAdi from
(
 select ROW_NUMBER() over(partition by MasaAdi order by ID,Ad ) as Sira,ID,Ad,MasaAdi
 from (
 select newid() as ID,Ad,MasaAdi 
 from #Personel
 cross join #Masa
 )t
 ) t2 where Sira = 1 order by Ad

This is the best syntax to emphasize that it is a cross join.

But on SQL Server 2008 your query gives the same result .

EDIT:

Your problem is not the select statement, but the inserts. Inserts with multiple value clauses is a new feature of SQL Server 2008. For 2005 you have to write:

insert into #Personel values('deneme1')
insert into #Personel values('deneme2')
insert into #Personel values('deneme3')

insert into #Masa values('Masa1')
insert into #Masa values('masa2')
insert into #Masa values('masa3')
