> SQL UDFs get a  [WrappedRow|https://github.com/apache/beam/blob/master/sdks/java/extensions/sql/src/main/java/org/apache/beam/sdk/extensions/sql/impl/rel/BeamCalcRel.java#L642], which is suppose to be an internal wrapper for BeamCalcRel. We should revisit how rows are passed to UDFs, possibly passing the Schema Row instead. At very least users need to be able to get columns by name.
