T-SQL - 合并两个表而不创建临时表

Question

The prefer result i want I have those 2 T-SQL queries:

SELECT 
    CONVERT(NVARCHAR, AL.FECHA, 103) AS [DATE], 
    CONVERT(NVARCHAR, AL.HORA, 108) AS [HOUR], 
    SUM(CAST(AL.TOTALNETO AS money)) AS [AMOUNT]
FROM
    ALBVENTACAB AL
WHERE 
    CONVERT(NVARCHAR, AL.FECHA, 103) = '10/09/2020' 
    -- AND CONVERT(nvarchar, GETDATE(), 103) AND
    AND CONVERT(nvarchar, AL.HORA, 108) BETWEEN (SELECT CONVERT(nvarchar, AL.HORA, 108)) AND CONVERT(nvarchar, GETDATE(), 108)
GROUP BY 
    AL.FECHA, AL.HORA
ORDER BY 
    AL.FECHA

SELECT 
    CONVERT(NVARCHAR, AL.FECHA, 103) AS [DATE], 
    CONVERT(NVARCHAR, AL.HORA, 108) AS [HOUR], 
    SUM(CAST(AL.TOTALNETO AS money)) AS [AMOUNT]
FROM 
    ALBVENTACAB AL
WHERE 
    FECHA = CAST(DATEADD(DD, -7, GETDATE()) AS date) 
    AND CONVERT(nvarchar, AL.HORA, 108) BETWEEN (SELECT CONVERT(nvarchar, AL.HORA, 108)) AND CONVERT(nvarchar, GETDATE(), 108)
GROUP BY 
    AL.FECHA, AL.HORA
ORDER BY 
    AL.FECHA

Individually, their results are correct. I want to create a result as shown in the screenshot.

I tried to create a CTE, but that didn't work. What is the proper way?

Thank you!

Answer 1

First, the query I think you're looking for is something like this. The Friday date (@fecha) was removed to a variable of type DATE. Instead of 2 query, 1 for the week, and 1 for the particular Friday, it's now 1 query. The friday sales are broken out using conditional aggregation into a new column called [FECHA_AMOUNT]. Note: this only works if the variable @fecha falls within the last 7 days.

declare @fecha          date='20201009';

SELECT 
    CONVERT(NVARCHAR, AL.FECHA, 103) AS [DATE], 
    CONVERT(NVARCHAR, AL.HORA, 108) AS [HOUR], 
    SUM(CAST(AL.TOTALNETO AS money)) AS [AMOUNT],
    SUM(case when cast(AL.FECHA as date)=@fecha then CAST(AL.TOTALNETO AS money) 
             else cast(0 as money) end) AS [FECHA_AMOUNT]
FROM 
    ALBVENTACAB AL
WHERE 
    FECHA = CAST(DATEADD(DD, -7, GETDATE()) AS date) 
    AND CONVERT(nvarchar, AL.HORA, 108) BETWEEN (SELECT CONVERT(nvarchar, AL.HORA, 108)) 
    AND CONVERT(nvarchar, GETDATE(), 108)
GROUP BY 
    AL.FECHA, AL.HORA
ORDER BY 
    AL.FECHA;

Finally, as note in the comments. When converting it's always good to use lengths. Also, the money data type is not considered ideal. Fwiw
