There are two main groups of ClickHouse settings:
2023-07-11 20:59:16 +00:00
- Global server settings
- Query-level settings
2023-07-11 20:59:16 +00:00
The main distinction between global server settings and query-level settings is that
global server settings must be set in configuration files while query-level settings
can be set in configuration files or with SQL queries.

2023-07-11 20:59:16 +00:00
Read about [query-level settings](/docs/en/operations/settings/settings-query-level.md) to learn more about configuring your ClickHouse server at the query-level.
