选择忽略日期在某个范围内的空值的记录

Question

我只想要那些在特定日期之间必须存在记录的记录。例如如果给定的日期在 2013-7-1 和 2013-7-17 之间，并且我在采购表中有一个条目，日期为：2013-6-5，而销售表中的条目日期为 2013-7-17，用于特定产品。它应该忽略这些行并仅选择在所需日期范围内发生销售和购买的那些行。我的以下查询无法正常工作。由于上面定义的情况除以零异常发生。请帮助我。

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

将HAVING SUM(sq.PQuantity) > 0 添加到查询的底部。
