これを試して。少し単純ですが、機能しています:)
create table my_query (
company1 nvarchar(100),
company2 nvarchar(100),
[year] int,
revenue int,
);
insert into my_query (company1, company2, [year], revenue) values ('A1', 'B1', 2000, 1000);
insert into my_query (company1, company2, [year], revenue) values ('B1', 'A1', 2001, 2000);
insert into my_query (company1, company2, [year], revenue) values ('A1', 'C1', 2000, 1500);
insert into my_query (company1, company2, [year], revenue) values ('C1', 'A1', 2001, 1400);
