# jdbc {#table-function-jdbc}
|
||
|
||
`jdbc(jdbc_connection_uri, schema, table)` -返回通过JDBC驱动程序连接的表。
|
||
|
||
此表函数需要单独的 `clickhouse-jdbc-bridge` 程序才能运行。
|
||
它支持可空类型（基于查询的远程表的DDL）。
|
||
|
||
**示例**
|
||
|
||
``` 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')
|
||
```
