What outcome can you expect if you apply the coalesce function to multiple fields?

When applying the coalesce function to multiple fields, you can expect it to return the first non-null value found in the provided fields. This behavior allows you to extract a meaningful data point from a series of fields, effectively identifying the first available value among them.

The coalesce function is particularly useful in scenarios where you have a dataset with optional fields or where some records might lack certain values. By focusing on the first non-null entry, it ensures that the output is a distinct and useful data point, which is why this choice is correct.

In contrast to other options, generating a list of unique field values does not align with the coalesce function since it provides a single output rather than a list. While it will return a null value if all fields are null, this outcome speaks to the function's behavior rather than to the primary outcome of querying for a data point. The function can be applied to a variety of data types, not exclusively numeric ones, further supporting the assertion that it returns one distinct data point rather than being limited to numeric values.
