Hi there.I see this description in doc:

If your query function depends on a variable, include it in your query key

So, I want to know.If I forget to pass a variable include into my query key and what will happen.Thanks.

In this case whenever this variable changes, your query would not update.
You could treat it as a dependency array like in other react hooks.
Additionally based on queryKey, cache entry is created. So if you do not include changing variable in queryKey, different queries might want to store data in the same place.
