create table #Personel
(
Ad varchar(100)
)

create table #Masa
(
MasaAdi varchar(100)
)

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')

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

它正在创建如下所示的结果。

deneme1 - masa2
deneme2 - masa3
deneme1 - masa1

好吧，它是能够将同一个人两次部署到不同的表。

e.g deneme1 - masa2
    deneme1 - masa1

我不想那样做。我想做如下所示的事情。

e.g deneme1-masa2
    deneme2-masa3
    deneme3-masa1

所以，我不想将同一个人两次部署到不同的表。

    with 
cte1 as
(
    select *, row_number() over(order by Ad) RowNumber
    from #Personel
),
cte2 as
(
    select *, row_number() over(order by newid()) RowNumber
    from #Masa
)
select cte1.Ad, cte2.MasaAdi
from cte1
    join cte2 on
        cte1.RowNumber = cte2.RowNumber
