JDBC Driver#
The Presto JDBC driver allows users to access Presto using Java-based applications, and other non-Java applications running in a JVM. Both desktop and server-side applications, such as those used for reporting and database development, use the JDBC driver.
Requirements#
The JDBC driver is compatible with Java versions 8 or higher, and can be used with applications running on Java virtual machines version 8 or higher.
Installing#
Download presto-jdbc-350.jar and add it to the classpath of your Java application.
The driver is also available from Maven Central:
<dependency> <groupId>io.prestosql</groupId> <artifactId>presto-jdbc</artifactId> <version>350</version> </dependency>
We recommend using the latest version of the JDBC driver. A list of all
available versions can be found in the Maven Central Repository. Navigate to the
directory for the desired version, and select the presto-jdbc-xxx.jar
file
to download, where xxx
is the version number.
Once downloaded, you must add the JAR file to a directory in the classpath of users on systems where they will access Presto.
After you have downloaded the JDBC driver and added it to your classpath, you’ll typically need to restart your application in order to recognize the new driver. Then, depending on your application, you may need to manually register and configure the driver.
Registering and configuring the driver#
Drivers are commonly loaded automatically by applications once they are added to its classpath. If your application does not, such as is the case for some GUI-based SQL editors, read this section. The steps to register the JDBC driver in a UI or on the command line depend upon the specific application you are using. Please check your application’s documentation.
Once registered, you must also configure the connection information as described in the following section.
Connecting#
When your driver is loaded, registered and configured, you are ready to connect to Presto from your application. The following JDBC URL formats are supported:
jdbc:presto://host:port
jdbc:presto://host:port/catalog
jdbc:presto://host:port/catalog/schema
The following is an example of a JDBC URL used to create a connection:
jdbc:presto://example.net:8080/hive/sales
This example JDBC URL locates a Presto instance running on port 8080
on
example.net
, with the catalog hive
and the schema sales
defined.
Connection parameters#
The driver supports various parameters that may be set as URL parameters,
or as properties passed to DriverManager
. Both of the following
examples are equivalent:
// URL parameters
String url = "jdbc:presto://example.net:8080/hive/sales";
Properties properties = new Properties();
properties.setProperty("user", "test");
properties.setProperty("password", "secret");
properties.setProperty("SSL", "true");
Connection connection = DriverManager.getConnection(url, properties);
// properties
String url = "jdbc:presto://example.net:8080/hive/sales?user=test&password=secret&SSL=true";
Connection connection = DriverManager.getConnection(url);
These methods may be mixed; some parameters may be specified in the URL, while others are specified using properties. However, the same parameter may not be specified using both methods.
