SQL聯盟所有「語法Eror in從句子」

Question

我很努力與MS Access 2010 SQL。任何人都可以看到爲什麼下面的SQL語句會在FROM子句中產生「語法錯誤？」

INSERT INTO Attendance 
SELECT [AttendanceData].Student, [AttendanceData].[10/1/2015] AS AttendValue, 
"10/1/15" AS AttendDate 
FROM [AttendanceData] 
UNION ALL 
SELECT [AttendanceData].Student, [AttendanceData].[10/2/2015] AS AttendValue, 
"10/2/15" As AttendDate 
FROM [AttendanceData]; 

個人陳述做工精細，但與UNION ALL結合，我收到

語法錯誤在FROM子句「。

任何幫助，將不勝感激！

謝謝

Answer 1

嘗試使用某些東西這樣的：

INSERT INTO Attendance 
SELECT R.Student, R.AttendValue, R.AttendDate 
FROM 
(
    (SELECT [AttendanceData].Student, [AttendanceData].[10/1/2015] AS AttendValue, 
    "10/1/15" AS AttendDate 
    FROM [AttendanceData]) 

    UNION ALL 

(SELECT [AttendanceData].Student, [AttendanceData].[10/2/2015] AS AttendValue, 
    "10/2/15" As AttendDate 
    FROM [AttendanceData]) 
) AS R 

Answer 2

在MS Access的Jet/ACE SQL，你不能在追加查詢使用聯合查詢直接。您將看到查詢調試器突出顯示UNION ALL語句。

將聯合查詢單獨保存爲存儲的查詢對象，然後將其用於追加查詢的SELECT語句中。

INSERT INTO Attendance 
SELECT * FROM UnionAttendance 

或者，你可以使用派生表：

INSERT INTO Attendance 
SELECT * 
FROM ( 
    SELECT [AttendanceData].Student, [AttendanceData].[10/1/2015] AS AttendValue, 
    "10/1/15" AS AttendDate 
    FROM [AttendanceData] 
    UNION ALL 
    SELECT [AttendanceData].Student, [AttendanceData].[10/2/2015] AS AttendValue, 
    "10/2/15" As AttendDate 
    FROM [AttendanceData] 
);
