Error message

setUnicodeStream

What it means

setUnicodeStream is explicitly unsupported in this driver: the override always throws SQLFeatureNotSupportedException. It signals that the JDBC 1.0-style Unicode character stream parameter API has no Presto implementation, independent of the supplied parameter index or stream.

Solutions

1. Use setString with a java.lang.String instead of a Unicode character stream
2. Set character data via setCharacterStream alternatives only if the driver implements them (it does not for this driver version)
3. Refactor code paths that rely on stream-based character parameters
