jdbc

Note

clickhouse-jdbc-bridge contains experimental codes and is no longer supported. It may contain reliability issues and security vulnerabilities. Use it at your own risk. ClickHouse recommend using built-in table functions in ClickHouse which provide a better alternative for ad-hoc querying scenarios (Postgres, MySQL, MongoDB, etc).

jdbc(datasource, schema, table) - returns table that is connected via JDBC driver.

This table function requires separate clickhouse-jdbc-bridge program to be running. It supports Nullable types (based on DDL of remote table that is queried).
