選擇記錄，忽略某些範圍之間的日期的空值

Question

我只想要記錄必須存在於特定日期之間的記錄。對於例如如果日期在2013年7月1日至2013年7月17日之間，並且我在2013年7月5日的購買表中輸入了日期爲2013-6-5的條目，並在2013-7-17日的銷售表中輸入了特定產品的條目。它應該忽略這些行並僅選擇那些在所需日期範圍內發生銷售的行。我的下面的查詢無法正常工作。由於上述定義的情況除以零發生異常。請幫助我。

SELECT  o.Name AS Owner, c.Name AS Company, SUM(sq.PQuantity) - SUM(sq.SQuantity) AS Quantity, SUM(sq.PQuantity * sq.PRate)/SUM(sq.PQuantity) AS Rate, 
          (SUM(sq.PQuantity) - SUM(sq.SQuantity)) * (SUM(sq.PQuantity * sq.PRate)/SUM(sq.PQuantity)) AS Amount,sq.CompanyId AS CompanyId, o.OwnerId AS OwnerId 
    FROM   (SELECT  OwnerId, CompanyId, Quantity AS PQuantity, RatePerShare AS PRate, 0 AS SQuantity, 0 AS SRate, Date 
           FROM   Purchase 
           UNION ALL 
           SELECT  OwnerId, CompanyId, Quantity AS PQuantity, 0 AS PRate, 0 AS SQuantity, 0 AS SRate, Date 
           FROM   Bonus 
           UNION ALL 
           SELECT  OwnerId, CompanyId, Quantity AS PQuantity, CostOfShare AS PRate, 0 AS SQuantity, 0 AS SRate, Date 
           FROM   RightShare 
           UNION ALL 
           SELECT  OwnerId, CompanyId, 0 AS PQuantity, 0 AS PRate, Quantity AS SQuantity, RatePerShare AS SRate, Date 
           FROM   Sales) AS sq INNER JOIN 
          Owner AS o ON sq.OwnerId = o.OwnerId INNER JOIN 
          Company AS c ON sq.CompanyId = c.CompanyId 
    WHERE  (sq.OwnerId = @Param1) AND (CONVERT(DATE, sq.Date, 111) BETWEEN @Param2 AND @Param3) 
    GROUP BY sq.CompanyId, c.Name, o.Name, o.OwnerId 

Answer 1

將HAVING SUM(sq.PQuantity) > 0添加到您的查詢底部。
