# Defining the Field Resolution Order in PQL

The PQL accepts the ; token to separate operations in the query, and it will be replaced with a series of self fields (as described in Manipulating the Field Resolution Order) when transforming from requested to executable query. This guarantees that the operations will be executed in the given order in the query.

For instance, this query:

/?query=
  posts.
    author.
      id|
      name|
      url;
  posts.
    comments.
      id|
      content

... is resolved as this one:

/?query=
  posts.
    author.
      id|
      name|
      url,
  self.
    self.
      posts.
        comments.
        id|
        content
