SQL Unpivot with row numbers

Question

我有一个UNPIVOT SELECT语句

SELECT dycd_acnam, dycd_dynam, dycd_value
FROM GCATT.dbo.tblDaycode UNPIVOT (
dycd_value FOR dycd_dynam IN (
    Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday)
) AS pvtDaycode
GROUP BY dycd_acnam, dycd_dynam, dycd_value

返回像

这样的值

dycd_acnam  |  dycd_dynam  |  dycd_value
----------------------------------------
MT          | Monday       | 1
MT          | Tuesday      | 1
MT          | Wednesday    | 0
MT          | Thursday     | 0

如何在行dycd_acnam之前添加行号?尝试RANK()，但它返回错误的值。我想尽量避免使用#Temp表

Answer 1

如果你只想在结果中添加一个递增列，你可以添加

ROW_NUMBER() OVER (ORDER BY (SELECT 0))

到SELECT列表
