将行转置为SQL Server 2015列

Question

需要帮助将数据从行转置为列

col1  col2   col3
-------------------
d1    d2      d3

结果应为

col
----
d1
d2
d3

Answer 1

使用交叉应用

;WITH CTE(col1,col2,col3)
AS
(
SELECT 'd1','d2','d3'
)
SELECT col FROM CTE
CROSS APPLY (VALUES(col1),(col2),(col3)) As Dt (col);

结果，看看演示：http://rextester.com/LVXO57980

col
---
d1
d2
d3

Answer 2

你可以用这个：

SELECT col1 AS col
FROM table_name
UNION ALL 
SELECT col2 AS col
FROM table_name
UNION ALL 
SELECT col3 AS col
FROM table_name
ORDER BY col;

Answer 3

使用此

Select col 
from tablename 
     unpivot ( 
        col
        FOR unpivot_columns IN ([col1],[col2],[col3])
     ) as unpvt;
