Answer 2

数据假设每隔一列是查询重复，并且没有ID柱最初

WITH T (FirstName, LastName,Ranking) 
AS 
(
SELECT 
    FirstName, 
    LastName, 
    2* ROW_NUMBER() OVER(ORDER First Name, Last Name) AS Ranking --, other columns 
FROM TBL 
) 

SELECT Name --, other columns 
FROM 
(
SELECT FirstName AS Name, 
Ranking-1 as r--, other columns 
FROM T 

UNION 

SELECT LastName AS Name, 
Ranking as r--, other columns 
FROM T 
) Tbl ORDER BY r ASC
