# Data Preview

The Data Preview feature generates a query that returns the first 10 records of a table or column. This gives users a quick glimpse of what data is present before writing a query.

To generate a Data Preview, follow the steps below:

* In the Schema Explorer, hover over any table or column name.
* Click the kebab (3 dots) icon that appears.
* Click **Data Preview**
* A new tab will open, displaying the first 10 rows of the selected table or column.

Do not write your final query in the tab opened using Data Preview as it will not auto-save, and there is a risk of losing work.
