Hi Try it out....

SQL

Insert into orders (orders_id, customers_id, customers_cid, customers_vat_id, customers_name, customers_email_address)
select
    o.*
from
    Test.dbo.orders o
where
    not exists (
        select 1
        from
            CobraDemoData.dbo.Data a
        where
            a.email0 = o.customers_email_address
    )

Also, you probably want to specify the columns in the select statement, just to make sure the right columns are transposed.
