# jdbc {#table_function-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**

```sql
SELECT * FROM jdbc('jdbc:mysql://localhost:3306/?user=root&password=root', 'schema', 'table')
```

```sql
SELECT * FROM jdbc('mysql://localhost:3306/?user=root&password=root', 'schema', 'table')
```

```sql
SELECT * FROM jdbc('datasource://mysql-local', 'schema', 'table')
```
