You can write a single ClickHouse query that combines the result of two queries by using subqueries.

You can use `WITH` to write subqueries, here’s example: <https://onelinerhub.com/clickhouse/using-subqueries-in-with-queries>

Also I am curious to know why you had to write clickhouse query?
For most of queries, query builder works. Have you tried query builder?

It says I've exhausted the amount of panels that can be created using query builder

You can upgrade to paid plan which will offer unlimited panels, alerts and more advanced features.

where can I check what features are available for free plan?
