我有一个运行良好的比较查询，但我有许多结果，我认为应该匹配的价格出现在不同的行中。有什么好方法可以让他们匹配给定的代码和帐户，以便将他们排除在我的结果集中吗？

询问：

with cteDev3 (Sequence, AccountID, SecurityID, Ticker, UniqueAccountID, BuyPrice, BuyDate, Shares)as
      (select Al.Sequence, Al.AccountID, al.SecurityID, s.Ticker,ad.UniqueAccountId, BuyPrice, BuyDate, Shares
        from dev3TM2.dbo.AccountLot al
        join dev3TM2.dbo.AccountDetails ad
        on al.AccountID = ad.AccountId
        join dev3TM2.dbo.Security s
        on al.SecurityId = s.SecurityId
        where ad.EnterpriseId = 'HuberFinancial'),
    cteTest2 (Sequence, AccountID, SecurityID,Ticker, UniqueAccountID, BuyPrice, BuyDate, Shares)as
       (select Al.Sequence, Al.AccountID, al.SecurityID, s.Ticker,ad.UniqueAccountId, BuyPrice, BuyDate, Shares
        from test2TM2.dbo.AccountLot al
        join test2TM2.dbo.AccountDetails ad
        on al.AccountID = ad.AccountId
        join Test2TM2.dbo.Security s
        on al.SecurityId = s.SecurityId
        where ad.EnterpriseId = 'HuberFinancial')

select c3.UniqueAccountId as 'Dev3', t2.UniqueAccountId as 'Test2',c3.Ticker, t2.Ticker,
       c3.Shares,t2.Shares, c3.BuyDate, t2.BuyDate, c3.BuyPrice as 'Dev3_BuyPrice', t2.BuyPrice as 'Test2_BuyPrice'
from cteTest2 t2 full outer join
     cteDev3 c3
     on c3.UniqueAccountId = t2.UniqueAccountId
where
--c3.UniqueAccountID is null or t2.UniqueAccountID is null and
        c3.SecurityID = t2.SecurityID and
        c3.BuyDate = t2.BuyDate and
       c3.Shares = t2.Shares and
        (c3.BuyPrice <= t2.BuyPrice -0.001 or c3.BuyPrice >=t2.BuyPrice + 0.001) 
        --c3.BuyPrice = t2.BuyPrice
order by c3.UniqueAccountID, t2.UniqueAccountID, c3.Ticker, t2.Ticker, c3.BuyDate, t2.BuyDate,
c3.BuyPrice, t2.BuyPrice

结果集（部分）：

也许我遗漏了一些东西，但是您看到的价格差异不到十分之一美分（好吧，我假设是美元）。

你给出的例子似乎相差这么多。

也许你应该尝试：

abs(c3.BuyPrice - t2.BuyPrice) >= 0.01

这将消除您拥有的大多数示例。

将价格和数量字段的类型从浮点更改。您不想要这种类型的舍入误差，各种会计师和认证机构也不想要。可以是内置的Money类型，也可以是带有您自己的刻度的整数类型来放置小数点，最好是前者。
