如何加入维度 table 的逆轴结果 table？

Question

这是我的测试环境

select * from dbo.fact1

IdRecordRedcap	FechaRegistro	TotalPruebas	TotalPruebasPositivas
1	2022-01-06	510	384
2	2022-01-07	300	184

 select * from dbo.DimMeasures

IdDimMeasures	NameMeasure
1	TotalPruebas
2	TotalPruebasPositivas

到目前为止，我能够运行包含 UNPIVOT 过程的查询，但我需要将它与 dbo.DimMeasures 结合起来，这样我才能得到 IdDimMeasures每个 NameMeasure

--UNPIVOT dbo.fact1
SELECT  u.FechaRegistro,
    u.NameMeasure,
    u.ValueMeasure 
FROM dbo.fact1 as x

UNPIVOT 
  (
     ValueMeasure
     for NameMeasure IN
     (
        TotalPruebas,
        TotalPruebasPositivas
    ) 
  ) AS u
GO

FechaRegistro	NameMeasure	ValueMeasure
2022-01-06	TotalPruebas	510
2022-01-06	TotalPruebasPositivas	384
2022-01-07	TotalPruebas	300
2022-01-07	TotalPruebasPositivas	184

Answer 1

SELECT  u.FechaRegistro,
        u.NameMeasure,
        u.ValueMeasure,
        m.IdDimMeasures
FROM dbo.fact1 as x

UNPIVOT 
  (
     ValueMeasure
     for NameMeasure IN
     (
        TotalPruebas,
        TotalPruebasPositivas
    ) 
  ) AS u
LEFT OUTER JOIN dbo.DimMeasures AS m
ON m.NameMeasure = u.NameMeasure;

输出：

FechaRegistro	NameMeasure	ValueMeasure	IdDimMeasures
2022-01-06	TotalPruebas	510	1
2022-01-06	TotalPruebasPositivas	384	2
2022-01-07	TotalPruebas	300	1
2022-01-07	TotalPruebasPositivas	184	2
