# jdbc {#table-function-jdbc}
`jdbc(jdbc_connection_uri, schema, table)` -返回通过JDBC驱动程序连接的表。

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')
