Which parameter can be used to specify which fields are brought from a join into an Explore?

• A. dimensions
• B. fields
• C. models
• D. tables

Answer: (B)

The parameter that can be used to specify which fields are brought from a join into an Explore is indeed "fields." This parameter allows developers to explicitly list the fields they want to include from a joined view when constructing an Explore. By explicitly defining the fields, it enhances the performance and readability of the Explore, as it avoids unnecessary data being retrieved and processed. Using the "fields" parameter ensures that only the specified fields are available in the Explore for users, allowing for a more tailored and efficient data experience. This approach is particularly valuable in scenarios where joins involve multiple fields, and the developer wants to limit the output to only those necessary for analysis. While "dimensions" refers to the types of fields defined in a LookML view, they are not a parameter specifically used in the context of joins in an Explore. "Models" generally refer to the overarching structure that contains explores and views but do not directly influence the field selection from a join. "Tables" could refer to database tables, but again, this does not indicate which fields are brought into an Explore from a join specifically. Overall, using "fields" provides precision in data retrieval and an optimized user experience when exploring data.
