獲取SQL Server 2012中無法綁定多部分標識符錯誤

Question

我在執行查詢後出現此錯誤。兩個表都有一列ID。我使用Microsoft SQL Server 2012

消息4104，級別16，狀態1，行
多部分標識符 「CDATA.ID」 無法綁定。

代碼：

INSERT INTO CDATA(Name, Mobile, Email, [Address], [Date]) 
    SELECT Name, Mobile, Email, [Address], [Date] 
    FROM CustomerData 
    WHERE CustomerData.ID != CDATA.[ID] 

Answer 1

要檢查是否戰績表已經存在，你可以使用NOT EXISTS：

INSERT INTO CDATA(Name, Mobile, Email, [Address], [Date]) 
SELECT Name, Mobile, Email, [Address], [Date] 
FROM CustomerData 
WHERE NOT EXISTS (SELECT 1 FROM CData WHERE CustomerData.ID = CDATA.[ID]); 

或者EXCEPT：

INSERT INTO CDATA(Name, Mobile, Email, [Address], [Date]) 
SELECT Name, Mobile, Email, [Address], [Date] 
FROM CustomerData 
EXCEPT 
SELECT Name, Mobile, Email, [Address], [Date] 
FROM CDATA;
