匹配在T-SQL多個條件存儲過程

Question

我被迫用以下結構（ScheduledEmails）的表工作，我希望找到最有效的方式來處理多個變量被設置爲1（真）

下面的腳本，如果只有一個選擇將只返回正確的值。

可能有人推薦的方式來修改底部查詢，以適應多個條件。

例如@IsMonday和@IsTuesday是真實的等？

我試過AND/OR的多種組合，但似乎沒有產生所需的結果。

DECLARE @IsMonday bit 
DECLARE @IsTuesday bit 
DECLARE @IsWednesday bit 
DECLARE @IsThursday bit 
DECLARE @IsFriday bit 
DECLARE @IsSaturday bit 
DECLARE @IsSunday bit 
DECLARE @Is0000 bit 
DECLARE @Is0100 bit 
DECLARE @Is0200 bit 
DECLARE @Is0300 bit 
DECLARE @Is0400 bit 
DECLARE @Is0500 bit 
DECLARE @Is0600 bit 
DECLARE @Is0700 bit 
DECLARE @Is0800 bit 
DECLARE @Is0900 bit 
DECLARE @Is1000 bit 
DECLARE @Is1100 bit

Answer 1

如果我明白你的要求正確，你只是想選擇從ScheduledEmails表星期和時間段當天的記錄，並將其插入到ScheduledEmailQueue表。如果情況確實如此，你可以創建一個動態的SQL查詢並執行它。如果我錯誤地理解你的要求的話，我提前:)

DECLARE @dayOfWeek VARCHAR(20) 
DECLARE @hourOfDay INT 
DECLARE @hourOfDayColumnName VARCHAR(20) 
DECLARE @dayOfWeekColumnName VARCHAR(20) 
DECLARE @sql VARCHAR(MAX) 

SET @dayOfWeek = datename(dw,GETDATE()) -- Monday to Sunday 
SET @hourOfDay = datepart(hh, GETDATE()) -- Single digit 0 - 23 
SET @hourOfDayColumnName = 'Send' + CASE WHEN LEN(@hourOfDay) = 1 THEN '0' + CONVERT(VARCHAR, @hourOfDay) ELSE CONVERT(VARCHAR, @hourOfDay) END + '00' 
SET @dayOfWeekColumnName = 'Send' + @dayOfWeek 
SET @sql = 'INSERT INTO ScheduledEmailQueue (ScheduledEmailId, Created) 
SELECT Id, GETDATE() FROM ScheduledEmails WHERE ' + @dayOfWeekColumnName + ' = 1 AND ' + @hourOfDayColumnName + ' = 1' 

PRINT @hourOfDayColumnName 
PRINT @dayOfWeekColumnName 
PRINT @sql 
EXEC (@sql) 

對不起道歉，我誤解你的問題，但我仍然不清楚您的要求。如果您使用的星期幾和小時，他們總是會把你返回奇異值（例如週一和22）。如果你想基於多種標準來選擇值，那麼你將不得不做這樣一個簡單的硬編碼查詢：

SELECT Id, GETDATE() FROM ScheduledEmails WHERE 
SendMonday= 1 AND 
SendTuesday = 1 AND 
Send0000 = 1 AND 
Send0100 = 1 

如果您不知道所需的天，事先小時的值，那麼你可以將它們傳遞作爲存儲過程的參數並用於過濾。
