Get your ClickHouse version
It's easy to forget the exact of version of ClickHouse you installed, so you might want an easy way to find it - thankfully, there is an easy way.
Use the following query to get your current ClickHouse version:
SELECT version()
If you're using the CLI, you can run this query as follows:
clickhouse-client -q "SELECT version()"
If you don't have the client, you can also do it over the HTTP interface
curl http://ch_host:8123/?q=select+version()
