What is the first step in creating a query parameter from distinct values?

The first step in creating a query parameter from distinct values is to create a query with the distinct values. This foundational step is critical because it allows you to define the set of unique values that will be used as parameters in subsequent queries or visualizations. By establishing this distinct set, you ensure that the parameter can be effectively tied to the specific data range you are interested in, allowing for more precise filtering and analysis.

Engaging with distinct values provides a structured way to generate a list of options that users can select from, enhancing the interactivity and utility of dashboards and reports. If you were to skip this step, the parameter may not function as intended, as there would be no predefined set of values to reference.

Subsequent actions, such as creating the parameter, specifying the column, or selecting a query, depend on having that initial set of distinct values available, making it a crucial starting point in the process.
