ms-access: отсутствует оператор в выражении запроса

Question

У меня есть этот sql оператор в доступе:

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];

все было хорошо, пока я не добавил последнюю строку:

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

я получаю эту ошибку:

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

Кто-нибудь знает, почему я получаю эту ошибку?

Вы пропустили запятую:

NULL,  [4 0 Other]
