<!-- Answer --> The reason your SQL works in clickhouse-client but fails in Superset is that Superset uses the sqlglot library to parse SQL, and sqlglot currently doesn't support the ON CLUSTER clause. Superset passes your SQL to the driver, and if sqlglot can't parse a clause, you'll get errors like the one you saw. There isn't any special handling for ON CLUSTER in Superset's ClickHouse integration—unsupported syntax just results in errors surfaced to the user [cite](https://github.com/apache/superset/blob/a1cbd2578e24ed6c72024e1d1cf195846ace05d7/superset/db_engine_specs/clickhouse.py). Workarounds discussed in the community include: running DDL like CREATE TABLE ... ON CLUSTER directly in ClickHouse (not through Superset), creating a view in ClickHouse that encapsulates your logic and querying that from Superset, or extending sqlglot to support the clause (which requires Python development) [cite](https://github.com/apache/superset/discussions/32345). If you need to run this kind of DDL from Superset, there isn't a built-in workaround—it's a limitation of the current SQL parsing layer. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
