# Verify your ClickHouse data

Confirm the data source works end to end by running a query in Explore. A simple `SELECT 1` confirms Grafana can query ClickHouse and get a result back, without needing access to any specific table.

To verify your data, complete the following steps.

1. In the navigation menu, click **Explore**.
2. From the data source dropdown at the top-left, select your ClickHouse data source.
   
   For example, select **ClickHouse observability**.
3. The editor opens in **Query Builder** mode by default. Switch it to **SQL Editor**.
   
   Skip this step if the editor is already set to **SQL Editor**.
4. In the SQL editor, enter a simple query to confirm the connection:
   
   SQL ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy
   
   ```sql
   SELECT 1
   ```
5. Click **Run query**.
   
   You should see a single row with the value `1` in the results panel below the editor. That confirms Grafana is querying ClickHouse successfully.

**Confirm successful access**

After running the query, you should see:

- A single row with the value `1` in the Explore results panel
- No connection errors or timeouts

**Congratulations!** You’ve connected ClickHouse to Grafana Cloud and confirmed it returns data.
