Return 单条记录的列作为行

Question

我已经在本网站以及其他网站上阅读了很多关于使用 PIVOT、UNPIVOT、UNION 和 CROSS JOIN 的帖子，但我似乎无法完全获得我正在寻找的结果。

我的 table 如下所示：

EmployeeName    Salary  Address             City        State   Zip     AdditionalDetails
=========================================================================================
Doe, John       400000  111 Jackson Ave     Nowhere     CA      99999   Reliable 
Blow, Joe       300000  222 Johnson St      Somewhere   ME      00000   Always late

我想展示的内容如下：

EmployeeName        Doe, John
Salary              400000
Address             111 Jackson Ave
City                Nowhere
State               CA
Zip                 99999
AdditionalDetails   Reliable

我最接近的是如下使用 UNPIVOT，但是，问题是两列被调换了，我需要交换它们，但我不确定该怎么做。

SELECT *
FROM
(
    SELECT EmployeeName, Salary, Address, City, State, Zip, AdditionalDetails
    FROM EmployeeDetails
    WHERE EmployeeDetails.EmployeeID=@EmployeeID
) AS SourceTable
UNPIVOT
(
    Value FOR Header IN
    (EmployeeName, Salary, Address, City, State, Zip, AdditionalDetails)
) AS UnpivotTable

所以我得到的是：

Value           Header
Doe, John       EmployeeName
400000          Salary
111 Jackson Ave Address
Nowhere         City
CA              State
99999           Zip
Reliable        AdditionalDetails

如何根据需要显示数据？我首先要说的是，此查询一次只会返回一条员工记录。我将此数据附加到 CSV 中，并请求以这种方式显示员工记录。

你快到了：

您的密码是：

SELECT *
FROM
(
    SELECT EmployeeName, Salary, Address, City, State, Zip, AdditionalDetails
    FROM EmployeeDetails
    WHERE EmployeeDetails.EmployeeID=@EmployeeID
) AS SourceTable
UNPIVOT
(
    Value FOR Header IN
    (EmployeeName, Salary, Address, City, State, Zip, AdditionalDetails)
) AS UnpivotTable

你应该有：

SELECT Header, Value
FROM
(
    SELECT EmployeeName, Salary, Address, City, State, Zip, AdditionalDetails
    FROM EmployeeDetails
    WHERE EmployeeDetails.EmployeeID=@EmployeeID
) AS SourceTable
UNPIVOT
(
    Value FOR Header IN
    (EmployeeName, Salary, Address, City, State, Zip, AdditionalDetails)
) AS UnpivotTable

结果：

Return 单条记录的列作为行
