MS-訪問：丟失的運算符在查詢表達式

Question

我有這樣的SQL語句訪問：

SELECT * 
FROM (SELECT [Occurrence Number], [1 0 Preanalytical (Before Testing)], NULL, NULL,NULL FROM [Lab Occurrence Form] 
WHERE NOT ([1 0 Preanalytical (Before Testing)] IS NULL) 
    UNION 
    SELECT [Occurrence Number], NULL, [2 0 Analytical (Testing Phase)], NULL,NULL FROM [Lab Occurrence Form] WHERE NOT ([2 0 Analytical (Testing Phase)] IS NULL) 
    UNION 
    SELECT [Occurrence Number], NULL, NULL, [3 0 Postanalytical (After Testing)],NULL FROM [Lab Occurrence Form] WHERE NOT ([3 0 Postanalytical (After Testing)] IS NULL) 
UNION 
    SELECT [Occurrence Number], NULL, NULL,NULL [4 0 Other] FROM [Lab Occurrence Form] WHERE NOT ([4 0 Other] IS NULL) 
) AS mySubQuery 
ORDER BY mySubQuery.[Occurrence Number]; 

一切都很好，直到我說的最後一行：

SELECT [Occurrence Number], NULL, NULL,NULL [4 0 Other] FROM [Lab Occurrence Form] WHERE NOT ([4 0 Other] IS NULL) 

我得到這個錯誤：

syntax error (missing operator) in query expression 'NULL [4 0 Other]' 

任何人都有任何線索爲什麼我得到這個錯誤？

Answer 1

你錯過了一個逗號：

NULL, [4 0 Other]
