SQL Server需要输出

Question

我有一张表格如下：

Country_ID | Country_name
-----------+-------------
    1      | India
    2      | Srilanka
    3      | South Africa
    4      | Australia

我现在需要一个查询来显示如下数据：

Match ID | Match Details
---------+---------------------------
    1    | India V/s Srilanka
    2    | India V/s South Africa
    3    | India V/s Australia
    4    | Srilanka V/s South Africa
    5    | Srilanka V/s Australia
    6    | South Africa V/s Australia

Answer 1

我想你想要自己加入更高ID的表

select
    row_number() over (order by a.country_id, b.country_id)
    , a.country_name + ' v/s ' + b.country_name
from
    myTable a
    join myTable b on a.country_id < b.country_id
