Which of the following is an example of a derived table in Looker?

A derived table in Looker is a virtual representation of a SQL query result. This means that instead of being a static physical table in a database, a derived table is created on-the-fly based on a specific SQL query. This allows users to define complex logic and transformations performed directly in LookML, and thus dynamically generate results based on the query each time it's called.

Derived tables enable analytics flexibility, allowing developers to create temporary tables that simplify or customize how data is presented. This functionality supports scenarios where aggregations or calculations need to be performed that don’t exist at the base level of the underlying database tables.

In contrast, creating a table from existing views relates more to using existing defined data structures rather than synthesizing new data from queries. Tables with records from a production database pertain to those physical data structures where data is directly stored and not dynamically generated. A physical table stored in a database is simply a concrete storage unit for data, rather than a flexible mechanism for representing SQL query results.
