[jira] [Created] (BEAM-11871) SQL UDFs don't work well with Row as an argument

Andrew Pilloud created BEAM-11871:
-------------------------------------

             Summary: SQL UDFs don't work well with Row as an argument
                 Key: BEAM-11871
                 URL: https://issues.apache.org/jira/browse/BEAM-11871
             Project: Beam
          Issue Type: New Feature
          Components: dsl-sql
            Reporter: Andrew Pilloud


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.
