# Displaying sample data for a column

{% hint style="info" %}
**Required workspace permission:**

* **Source data:** Preview source data
* **Destination data:** Preview destination data
  {% endhint %}

For each column on **Database View**, you can display a sample list of the column values.

For columns that have an assigned generator, the sample shows both the current values and the possible values after the generator is applied.

To display the sample values, in the **Column** column, click the magnifying glass icon.

If the generator is Passthrough, then the sample data panel contains only **Original Data**.

If a different generator is assigned, then the sample data panel contains both **Original Data** and **Protected Output**.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.tonic.ai/app/generation/database-view/database-view-sample-data.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
