返回不符合连接的行-Gettingrowsreturnedthatdon'tconformtoaJOIN

I have two types of rows in a table:

表中有两种类型的行:

There is the standard data, which is tied to a taskId and is loaded into the database during a process, the first two rows below are this type of data. The second type of data is not loaded in the process, it is inserted as part of a form. YOu can see the difference because the first type of data has a taskId and NonScrumStoryId is NULL. In the second case, NonScrumStoryId column is populated and TaskId is NULL.

有一个标准数据，它绑定到一个taskId并在处理过程中加载到数据库中，下面的前两行是这种类型的数据。第二种类型的数据不会被加载到流程中，而是作为表单的一部分插入。您可以看到差异，因为第一类数据有一个taskId，而非scrumstoryid为空。在第二种情况下，非scrumstoryid列是填充的，而TaskId是NULL。

I have a query to get data from this table:

我有一个查询来从表中获取数据:

My problem is that this query is only returning rows from the table that are from the process, it is not returning NonScrumStory columns and I need it to.

我的问题是，这个查询只返回来自流程的表中的行，它不返回非scrumstory列，我需要它。

Edit: It appears part of the WHERE clause is causing the issue.

编辑:它会出现WHERE子句的一部分，导致问题。

Ater investigation it probably has to do with this line:

之后的调查可能与这条线有关:

AND PDT.PK_Product LIKE @productId

How can I remedy this?

我该如何补救?

LEFT JOIN Task TSK ON DTH.TaskId = TSK.PK_Task

LEFT JOIN Story STY ON TSK.StoryId = STY.PK_Story

LEFT JOIN Product PDT ON STY.ProductId = PDT.PK_Product

AND PDT.PK_Product LIKE @productId

...
AND ActivityDate <= @endDateParam
AND (@productId IS NULL OR PDT.PK_Product LIKE @productId)
AND (
