Question

SELECT TOP 1000 
    TGL = CONVERT(DATE, TIMESTAMP), RIGHT('0' + CAST(DATEPART(hour, TimeStamp) AS VARCHAR(2)), 2) AS jam,
    Nilai = MAX(NILAI)
FROM 
    PLC_CPress2P1 
GROUP BY 
    CONVERT(DATE, TIMESTAMP), RIGHT('0' + CAST(DATEPART(hour, TimeStamp) AS VARCHAR(2)), 2)
ORDER BY 
    CONVERT(DATE, TIMESTAMP), RIGHT('0' + CAST(DATEPART(hour, TimeStamp) AS VARCHAR(2)), 2) DESC

我已尝试GATEDATE()和NOW - 两者都无效

Answer 1

我认为你试图从日期等于今天的表格中选择一次？

在这种情况下，您可以这样做：

SELECT *columns*
FROM *table_name*
WHERE *specified_date_column* = CAST(GETDATE() as date)

在这里，您可以看到所有SQL Date函数：https://www.w3schools.com/sql/sql_dates.asp
