Error message

getSQLXML

What it means

PrestoResultSet has no SQLXML support: getSQLXML is a stub that unconditionally throws SQLFeatureNotSupportedException, echoing the method name. Calling it to fetch an XML-typed column is the trigger; the driver never produces this error on its own.

Solutions

1. Read XML data as a String with getString and parse it in application code
2. Use VARCHAR-typed columns for XML content instead of SQLXML mappings
3. Avoid SQLXML APIs with the Presto JDBC driver
