The _____________ parameter provides alternative names for a field that might appear in the URL for a query.

The alias parameter allows developers to define alternative names for a field within Looker, which can be particularly useful in providing more meaningful or user-friendly names in the context of URLs generated for queries. This becomes essential when the default field names may be unintuitive or difficult for end-users to understand. By using the alias parameter, developers can ensure that the field's representation in the URL is clearer and more aligned with the language that users expect or understand, improving the overall usability of the Looker instance.

On the other hand, the label parameter refers to the human-readable name displayed for a field in the Looker interface, while the title parameter is often used to set the title of a dashboard or a visual representation, rather than for fields in URLs. The name parameter is typically the identifier for the field within Looker and does not serve to provide alternative names specifically for URLs.
