日付範囲の間にテーブルの結合を選択する

Question

endDateまたはstartDateのいずれかが範囲外である複数のテーブルを選択しようとしています。

SELECT * 
FROM excel.construction 
GROUP BY startDate, 
     endDate 
UNION ALL 

SELECT * 
FROM excel.misc 
GROUP BY startDate, 
     endDate 
UNION ALL 

SELECT * 
FROM excel.spawar 
GROUP BY startDate, 
     endDate 
WHERE construction.startDate BETWEEN '2012-01-01' AND '2012-01-10' 
    OR construction.endDate BETWEEN '2012-01-01' AND '2012-01-10' 
    OR misc.startDate BETWEEN '2012-01-01' AND '2012-01-10' 
    OR misc.endDate BETWEEN '2012-01-01' AND '2012-01-10'; 

なぜこの方法ではうまくいかないのですか？

     misc.endDate BETWEEN '2012-01-01' AND '2012-01-10';m
