# Run first query

> Confirm your Serverless e6data deployment on AWS works by running a query against your catalog.

With a catalog connected and a cluster running, run a query to confirm the deployment works end to end.

## Run a query

1. In the Compute Plane, open the **SQL Editor**.
2. Select the cluster you created and the catalog you connected.
3. Run a simple query against a table you can see, for example:

```sql theme={"theme":{"light":"github-light","dark":"github-dark"}}
SELECT * FROM your_catalog.your_schema.your_table LIMIT 10;
```

4. Confirm that results return in the results pane.

If the query succeeds, your AWS Serverless deployment is working: the cluster reached your catalog metadata and read your S3 data through the cross-account role.

## If the query fails

* A `403`-style or access error usually means the cross-account IAM role is missing an S3 or Glue permission, or its ARN isn't registered. Revisit [Configure AWS access](/platform/deploy/aws-serverless/configure-aws-access).
* A connection or schema error usually points to the catalog. Revisit [Connect S3 and Glue](/platform/deploy/aws-serverless/connect-s3-and-glue) and use **Test Connection**.
* See [Troubleshooting](/platform/deploy/aws-serverless/troubleshooting) for the full list.

## Next steps

* [Query editor](/query/querying/query-editor) - write and run queries.
* [Connect a BI tool](/query/connect/tableau) - query e6data from Tableau, DBeaver, and more.
* [Create and manage clusters](/query/clusters/create-and-manage) - size, scale, and manage compute.
