推荐答案

<$ c中有一列父_id $ c>问题表。我想你可以使用它。



对于两个问题你现在使用...... 和你是吗？暴露于... ，你可以将Column Parent_id 更新为5，即 Answer_Id 在答案表中当前吸烟者。



这样，您可以联系。因此，当选择当前吸烟者时，您查询问题表格如...

There is one Column Parent _id in Question Table. I guess you can use that.

For the two questions "Do you currently use..." and "Are you exposed to...", you can update the Column Parent_id to 5, which is the Answer_Id for "Current Smoker" in Answer Table.

This way, you can relate. So, when "Current Smoker" is selected, you query to Question Table like...

SELECT Question_Id, Question FROM Questions WHERE Parent_id = 5

5（ Answer_Id ）在查询时从代码后面传递。



有意义吗？

5 (Answer_Id) is passed from code behind while querying.

Makes sense?
