SQL Server 2008 R2 将一行结果拆分为两行

Question

简单来说，table (t1) 看起来像这样：

id     hours    dollars
-----------------------
abc     4         40

我想从 table 中获得如下所示的结果：

abcHours      4      0
abcDollars    0      40

谢谢

Answer 1

您可以使用 cross apply 取消透视：

select x.*
from mytable t
cross apply (values 
    (concat(id, 'Hours'  ), hours, 0      ), 
    (concat(id, 'Dollars'), 0,     dollars)
) as x(newid, hours, dollars)

Answer 2

您可以尝试使用运算符 Union 进行简单查询：

Select  'abcHours' as  abcHour, hours as Hour, 0 as dollar
Union all
Select  'abcDollars', 0, dollars
