jdbc
jdbc(jdbc_connection_uri, schema, table)
- возвращает таблицу, соединение с которой происходит через JDBC-драйвер.
Для работы этой табличной функциии требуется отдельно запускать приложение clickhouse-jdbc-bridge. Данная функция поддерживает Nullable типы (на основании DDL таблицы к которой происходит запрос).
Пример
SELECT * FROM jdbc('jdbc:mysql://localhost:3306/?user=root&password=root', 'schema', 'table')
SELECT * FROM jdbc('mysql://localhost:3306/?user=root&password=root', 'schema', 'table')
SELECT * FROM jdbc('datasource://mysql-local', 'schema', 'table')
