Error executing query in Java code to connect to Presto - jdbc

Question

We are trying to connect to Presto using Java code and execute some queries. Catalog we are using is MySQL.
Presto is installed on the Linux server. Presto CLI is working fine on Linux. Started Presto in Linux.
MySQL is also installed on the Linux machine. We are able to access MySQL in windows using DbVisualizer.
I created a MySQL connector catalog for Presto. I'm successful in querying data of MySQL using Presto CLI as presto --server localhost:8080 --catalog mysql --schema tutorials.
Executing the Java code on the Windows machine, I'm able to access MySQL and execute queries, but we are unable to query data. When we try to run a query from Presto, it is giving us Error Executing Query. In the below example, I have used a jar from Trinosql
package testdbPresto;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.Properties;
public class PrestoJdbc {
public static void main(String args[]) throws SQLException, ClassNotFoundException {
try{
//connect mysql server tutorials database here
Class.forName("com.facebook.presto.jdbc.PrestoDriver");
String url = "jdbc:trino://35.173.241.37:8080/mysql/tutorials";
Properties properties = new Properties();
properties.setProperty("user", "root");
properties.setProperty("password", "Redcar88!");
properties.setProperty("SSL", "true");
Connection connection = DriverManager.getConnection(url, properties);
Statement statement = null;
statement = connection.createStatement();
//select mysql table author table two columns
String sql;
sql = "select auth_id, auth_name from mysql.tutorials.author";
ResultSet resultSet = statement.executeQuery(sql);
//Extract data from result set
while (resultSet.next()) {
//Retrieve by column name
String name = resultSet.getString("auth_name");
//Display values
System.out.println("name : " + name);
}
//Clean-up environment
resultSet.close();
statement.close();
connection.close();
}catch(Exception e){ e.printStackTrace();}
}
}
Output:

Answer 1

It is quite old question but it might be still relevant.
You are trying connect to trino with presto jdbc driver. PrestoSQL was rebranded as Trino . So in order to access trino via jdb, you should use trino jdbc driver.
Add trino dependency in your classpath.
If you use maven, add this dependency in the pom.
<dependency>
<groupId>io.trino</groupId>
<artifactId>trino-jdbc</artifactId>
<version>${trino-jdbc.version}</version>
</dependency>
Then use the following driver
Class.forName("io.trino.jdbc.TrinoDriver");

Answer 2

Here is a code that works with Trino.
fun main() {
val trinoUrl = "jdbc:trino://myDomain:443"
val properties = Properties()
properties.setProperty("user", "noUserS")
// properties.setProperty("password", "noPass")
properties.setProperty("SSL", "true")
DriverManager.getConnection(trinoUrl, properties).use { trinoConn ->
trinoConn.createStatement().use { statement ->
statement.connection.catalog = "catalog1"
statement.connection.schema = "default"
println("Executing query...")
statement.executeQuery("""
select
restaurantId,
type,
time
from table1
where time > CURRENT_TIMESTAMP - INTERVAL '1' hour
""".trimIndent()
).use { resultSet ->
val list = mutableListOf<Map<String, String>>()
while (resultSet.next()) {
val data = mapOf(
"restaurantId" to resultSet.getString("restaurantId"),
"type" to resultSet.getString("type"),
"time" to resultSet.getString("time")
)
list.add(data)
}
println("Records returned: ${list.size}")
println(list)
}
}
}
exitProcess(0)
}
It is Kotlin, but it's easy to understand.
The .use {..} it's try-with-resources in Java.
Hope this helps.
