+## Creating virtual (SQL) datasets
+
+In the Analytics admin portal, a dataset can be created from:
+
+* A physical table or view (select it from the **Table** dropdown).
+* A **virtual dataset**, defined by a SQL query.
+
+Create a virtual dataset in the Analytics admin portal by using the portal’s dataset creation flow and providing a SQL query.
+
+### Tips and best practices
+
+* Enter a non-empty SQL query. Creating a virtual dataset requires SQL that is not empty or whitespace.
+
+### Troubleshooting
+
+* **Dataset creation fails with an “SQL query cannot be empty or whitespace” error**: Edit the dataset and provide a SQL query with at least one non-whitespace character.
+
+## When a dataset already exists
+
+When creating datasets programmatically (for example, via internal services that call the analytics API), dataset creation can be configured to either:
+
+* **Reuse** an existing dataset when the dataset already exists.
+* **Recreate** an existing dataset by deleting it first and then creating a new one (a delete-and-recreate flow).
