的SQL Server連接兩個表

Question

我想兩個表的結果結合起來，因爲當我單獨做，我得到的空值的結果

這是我的代碼有

DECLARE @origSiteID int = 836, 
    @NewSiteID int = 838 


SELECT tblControls_Rooms.ID, @origSiteID 
FROM tblControls_Rooms 
WHERE SiteID = @OrigSiteID 

SELECT tblControls_Rooms.ID, @NewSiteID 
FROM tblControls_Rooms 
WHERE SiteID = @newSiteID 

當我運行它：

ID (No column name) 
1942 836 
1943 836 
1944 836 
1945 836 
1946 836 

和

ID (No column name) 
2025 838 
2026 838 
2027 838 
2028 838 

我想要得到的結果是：

ID (No column name) 
1942 836 
1943 836 
1944 836 
1945 836 
1946 836 
2025 838 
2026 838 
2027 838 
2028 838 

Answer 1

聯盟會的工作，你也可以使用...

SELECT ID, SiteID 
FROM tblControls_Rooms 
WHERE SiteID IN (@OrigSiteID, @NewSiteID) 

Answer 2

我認爲這會爲你工作：

SELECT DISTINCT(tblControls_Rooms.ID), tblControls_Rooms.SiteID 
FROM tblControls_Rooms 
WHERE SiteID = @OrigSiteID 
OR SiteID = @newSiteID 

你可能不需要DISTINCT
