No, we have not. I filled a support ticket with Snaplogic and here is the out come of that. Given that there are other tools which can interface with Presto via JDBC, IMHO Snaplogic would have to build a custom snap pack for Presto to be able to support it.
1.We have checked on below behaviour and we are getting the same error as “Method Connection.prepareStatement is not yet implemented” in Generic JDBC - Select Snap.Please find the attached screenshot.
2.We have investigated more on this and found that it’s a known issue with Presto Jar files and still occurring in the latest presto-jdbc-0.187.jar file.They have not fixed the issue yet due to this we are getting errors in Generic JDBC - Select and Generic JDBC - Execute Snaps.Please find the below link for more information for the SQL error.

I'm using presto-jdbc-0.66-SNAPSHOT.jar, and trying to execute presto query to p… resto-server on my java application.
Below sample code, using jdbc statement, is working well.
```
Class.forName("com.facebook.presto.jdbc.PrestoDriver");
Connection connection = DriverManager.getConnection("jdbc:presto://192.168.33.33:8080/hive/default", "hive", "hive");
Statement statement = connection.createStatement();
ResultSet rs = statement.executeQuery("SHOW TABLES");
while(rs.next()) {
System.out.println(rs.getString(1));
}
```
However, using jdbc preparedstatement, throw exception.
Is presto-jdbc not support yet "preparedstatement" ?
Here's my test code and exception info.
Test Code :
```
Class.forName("com.facebook.presto.jdbc.PrestoDriver");
Connection connection = DriverManager.getConnection("jdbc:presto://192.168.33.33:8080/hive/default", "hive", "hive");
PreparedStatement ps = connection.prepareStatement("SHOW TABLES");
ResultSet rs = ps.executeQuery();
while(rs.next()) {
System.out.println(rs.getString(1));
}
```
Exception Info :
```
