jdbc

jdbc(jdbc_connection_uri, 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).

Examples

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')
