Question

我有5张与亲子关系的桌子

UserInfo
UserInformation
UserEntryEntry
用户信息
UserBusket

在父子关系中，我的意思是（userInfo的recordId是UserInfo中的主键，UserInformation和UserEntryEntry中的外键，在下表中保持相同的关系）我必须做出一个视图，在该视图中我应该重新聚集所有这五个表的记录数据。主要问题是：

1.IN UserInformation我有重复的数据，我想那不是因为它有关于用户的预注册，注册和编辑信息的记录，并且除了date之外，它们没有其他任何值，在我尝试使用的以下代码中max（datetime）但似乎不起作用，w 我应该怎么做解决此重复问题？

该视图以某种方式复制了view，而我找不到，执行此操作的原因是什么。（我应该有15条记录，然后再按15条显示）

图片上的这是我表的原始数据示例以及所需结果： enter image description here

基于对[UserInformation]表的解释，似乎有多种类型的事务存储为行，以进行预注册，注册和编辑信息。

我不确定您拥有的数据集，但是假设[UserInformation]中每个用户至少有一条记录，如果这样的话，我们可以将其更改为INNER JOIN而不是LEFT OUTER。

根据要从具有预注册，注册和编辑信息的用户那里得到的输出，您必须执行另一个加入过滤条件，如

,SUM(ProductTaxCalculate. Payments) AS TotalPayments
        FROM [UserInfo] Incoming WITH (NOLOCK)
        INNER JOIN [UserInformation] DeclInf WITH (NOLOCK)
        ON DeclInf.IncomingGUID = Incoming.IncomingGUID 
        AND transactiontype ='pre-registration'

我认为您应该将

AND transactiontype ='pre-registration'标识为其他列。
