Alexa內置插槽AMAZON.DATE

Question

使用內置插槽AMAZON.DATE時，根據developer reference將「下週」解釋爲2016-W38。

話語映射到只是一個特定的星期（如「本週」或 「下週」），轉換日期指示週數：2015年-W49。

我想解析這在SQL中。在使用Alexa服務時，是W1或W01年的第一週？謝謝。

Answer 1

更新：日期採用ISO-8601日期格式。第一週是W01，沒有W00。

參考：https://en.wikipedia.org/wiki/ISO_8601#Dates

原來的答覆：

我找不到文檔，但在這裏就是答案......

• 今天是星期三28日，272日。
• Alexa說這是2016-W39。 （我剛剛檢查過）。
• 2016年在星期五開始，所以W39在上週五的267天開始，這是1月1日之後的38周。 （7分之267= 38.14）。
• 算回38周到年初。

因此，一年的第一週稱爲W1。

這就是我最終使用SQL Server存儲過程解析AMAZON.DATE內置插槽的方式。

CREATE PROCEDURE [dbo].[procMomaAlexaExhibitions] 

@p_alexa_date VARCHAR(50) = '' 

AS 
BEGIN 

SET NOCOUNT ON; 

DECLARE @p_start_date VARCHAR(10) = '' 
DECLARE @p_end_date VARCHAR(10) = '' 

--SET @p_alexa_date = '2015-W20-WE' 

-- Today if null 
IF(@p_alexa_date = '' OR @p_alexa_date IS NULL) 
BEGIN 
SET @p_start_date = (SELECT CONVERT(VARCHAR(10), GETDATE(), 121)) 
SET @p_end_date = (SELECT CONVERT(VARCHAR(10), GETDATE(), 121)) 
END 

-- Alexa provided a normal date 
IF(ISDATE(@p_alexa_date) = 1) 
BEGIN 
SET @p_start_date = CONVERT(VARCHAR(10), @p_alexa_date, 121) 
SET @p_end_date = CONVERT(VARCHAR(10), @p_alexa_date, 121) 
END 

-- Alexa provided a year-month 
IF(LEN(@p_alexa_date) <= 8 AND ISNUMERIC(REPLACE(@p_alexa_date,'-','')) = 1) 
BEGIN 
SET @p_start_date = @p_alexa_date + '-01' 
SET @p_end_date = @p_alexa_date + '-31' 
END 

-- weekend 
IF(RIGHT(@p_alexa_date, 3) = '-WE') 
    BEGIN 
    DECLARE @p_week VARCHAR(2) 
    DECLARE @p_year VARCHAR(4) 
    DECLARE @p_start_date_wk VARCHAR(10) = '' 
    DECLARE @p_end_date_wk VARCHAR(10) = '' 

    SET @p_week = REPLACE(SUBSTRING(@p_alexa_date,7, LEN(@p_alexa_date)),'-WE','') 
    SET @p_year = LEFT(@p_alexa_date, 4) 

    SET @p_start_date_wk = CONVERT(VARCHAR(10), DATEADD(wk, DATEDIFF(wk, 6, '1/1/' + @p_year) + (@p_week-1), 6), 121) 
    SET @p_end_date_wk = CONVERT(VARCHAR(10), DATEADD(wk, DATEDIFF(wk, 5, '1/1/' + @p_year) + (@p_week-1), 5), 121)  

    SET @p_start_date = CASE WHEN datename(weekday, CAST(@p_start_date_wk AS smalldatetime)) = 'Saturday' THEN CONVERT(VARCHAR(10), CAST(@p_start_date_wk AS smalldatetime), 121) 
          WHEN datename(weekday, CAST(@p_start_date_wk AS smalldatetime) + 1) = 'Saturday' THEN CONVERT(VARCHAR(10), CAST(@p_start_date_wk AS smalldatetime) + 1, 121) 
          WHEN datename(weekday, CAST(@p_start_date_wk AS smalldatetime) + 2) = 'Saturday' THEN CONVERT(VARCHAR(10), CAST(@p_start_date_wk AS smalldatetime) + 2, 121) 
          WHEN datename(weekday, CAST(@p_start_date_wk AS smalldatetime) + 3) = 'Saturday' THEN CONVERT(VARCHAR(10), CAST(@p_start_date_wk AS smalldatetime) + 3, 121) 
          WHEN datename(weekday, CAST(@p_start_date_wk AS smalldatetime) + 4) = 'Saturday' THEN CONVERT(VARCHAR(10), CAST(@p_start_date_wk AS smalldatetime) + 4, 121) 
          WHEN datename(weekday, CAST(@p_start_date_wk AS smalldatetime) + 5) = 'Saturday' THEN CONVERT(VARCHAR(10), CAST(@p_start_date_wk AS smalldatetime) + 5, 121) 
          WHEN datename(weekday, CAST(@p_start_date_wk AS smalldatetime) + 6) = 'Saturday' THEN CONVERT(VARCHAR(10), CAST(@p_start_date_wk AS smalldatetime) + 6, 121) 
          END 
    SET @p_end_date = CASE WHEN datename(weekday, CAST(@p_end_date_wk AS smalldatetime)) = 'Sunday' THEN CONVERT(VARCHAR(10), CAST(@p_end_date_wk AS smalldatetime), 121) 
          WHEN datename(weekday, CAST(@p_end_date_wk AS smalldatetime) + 1) = 'Sunday' THEN CONVERT(VARCHAR(10), CAST(@p_end_date_wk AS smalldatetime) + 1, 121) 
          WHEN datename(weekday, CAST(@p_end_date_wk AS smalldatetime) + 2) = 'Sunday' THEN CONVERT(VARCHAR(10), CAST(@p_end_date_wk AS smalldatetime) + 2, 121) 
          WHEN datename(weekday, CAST(@p_end_date_wk AS smalldatetime) + 3) = 'Sunday' THEN CONVERT(VARCHAR(10), CAST(@p_end_date_wk AS smalldatetime) + 3, 121) 
          WHEN datename(weekday, CAST(@p_end_date_wk AS smalldatetime) + 4) = 'Sunday' THEN CONVERT(VARCHAR(10), CAST(@p_end_date_wk AS smalldatetime) + 4, 121) 
          WHEN datename(weekday, CAST(@p_end_date_wk AS smalldatetime) + 5) = 'Sunday' THEN CONVERT(VARCHAR(10), CAST(@p_end_date_wk AS smalldatetime) + 5, 121) 
          WHEN datename(weekday, CAST(@p_end_date_wk AS smalldatetime) + 6) = 'Sunday' THEN CONVERT(VARCHAR(10), CAST(@p_end_date_wk AS smalldatetime) + 6, 121) 
          END 
    END 

-- not a weekend 
IF((@p_alexa_date LIKE '%-W%') AND (RIGHT(@p_alexa_date, 3) <> '-WE')) 
    BEGIN 

    SET @p_week = SUBSTRING(@p_alexa_date,7, LEN(@p_alexa_date)) 
    SET @p_year = LEFT(@p_alexa_date, 4) 

    SET @p_start_date = CONVERT(VARCHAR(10), DATEADD(wk, DATEDIFF(wk, 6, '1/1/' + @p_year) + (@p_week-1), 6), 121) 
    SET @p_end_date = CONVERT(VARCHAR(10), DATEADD(wk, DATEDIFF(wk, 5, '1/1/' + @p_year) + (@p_week-1), 5), 121)  

    END 

從那裏你可以在SQL中做這樣的事情。 FYI

WHERE (ExhVenuesXrefs.BeginISODate <= @p_start_date) 
AND (ExhVenuesXrefs.EndISODate >= @p_end_date)
