joins to the same table

  • Hi,

    I have a transaction table where I have 'receivedby' and 'orderedby' columns. Both the columns are referring the StaffID of Emptable.

    I have to get received by and ordered by in the same query with the relevant names.

    declare @staff table(id int identity(1,1), Name varchar(10))

    insert into @staff values('abc')

    insert into @staff values('def')

    insert into @staff values('ghi')

    insert into @staff values('klm')

    declare @order table(id1 int identity(1,1), orderby int, receivedby int)

    insert into @order values( 1,2)

    insert into @order values( 2,2)

    insert into @order values( 3,2)

    insert into @order values( 4,2)

    insert into @order values( 4,4)

    select * from @staff

    select * from @order

    select id1

    ,orderby

    ,m.Name orderbyname

    ,m1.Name receivedbyname

    from @staff m

    inner join @order t

    on m.id = t.orderby

    inner join @staff m1

    on t.receivedby = m.id

    In the above code i would like to get the name of the staff in the place of order by and received by.

    Thanks,

    Ami

  • What would be your expected result other than what you already have?

    Isn't the result already what you're looking for?

  • Hi,

    I would like to get result like

    1abcdef

    2defdef

    3ghidef

    4klmdef

    5klmklm

    where the relevant names for the orderedby and receivedby staffids.

    thanks,

  • All you have to do is replace the m in the last line with m1 in your query

    select id1

    ,orderby

    ,m.Name orderbyname

    ,m1.Name receivedbyname

    from @staff m

    inner join @order t

    on m.id = t.orderby

    inner join @staff m1

    on t.receivedby = m1.id
