In Databricks SQL, a single query can serve as the data source for multiple, distinct visualizations. The standard workflow is to execute the query once, then create the first visualization from the results. Subsequently, you can create a second, different visualization from the same query results. Both of these independently created visualizations can then be added to a single dashboard. This approach is efficient as it avoids redundant query execution and maintenance, directly accomplishing the user's goal of having two visualizations from one query on one dashboard.

A. They will need to alter the Query to return two separate sets of results.

This is incorrect. A single result set from one query is sufficient to create multiple different visualizations.

C. They will need to create two separate dashboards.

This is incorrect. The objective is to add both visualizations to the same dashboard, which is a standard feature.

D. They will need to decide on a single data visualization to add to the dashboard.

This is incorrect as it contradicts the requirement to add two visualizations.

E. They will need to copy the Query and create one data visualization per query.

This is an inefficient and unnecessary step. Databricks SQL is designed to support creating multiple visualizations from a single query object.

1. Databricks Documentation

"Create and manage dashboards in Databricks SQL": This document outlines the process of adding visualizations to dashboards. It states

"You can add visualizations and text boxes to dashboards." The process described involves adding existing visualizations from queries

implying a many-to-one relationship (many visualizations to one dashboard).

Reference: Databricks SQL Guide > Dashboards > Create and manage dashboards in Databricks SQL.

2. Databricks Documentation

"Work with query results": This page explicitly confirms that a single query can have multiple visualizations.

Quote: "You can work with query results in the SQL editor to create visualizations and dashboards. ... You can create multiple visualizations on different tabs to help you interpret your query results."

Reference: Databricks SQL Guide > Queries > Work with query results.

3. Databricks Documentation

"Visualizations in Databricks": This document details how to create visualizations from query results. The interface allows adding a new visualization via a + button on the results tab

which can be done multiple times for the same query result set.
