Not sure if I'm reading Puma logs right. So I'd like to clarify three things:

***First*** 

If in controller we do something like:

```
def find_user
  user = User.where(name: "Alex")
  @user = user.where(age: 25)
end

```

How many sql queries are made?

***Second***

```
def find_user
  user = User.where(name: "Alex")
  @user = user
end

```

The same question.

***Third***

```
def find_user
  user = User.find(1).id
  @user = User.find(1).first_name
end

```

The same question.
