[jira] [Updated] (CALCITE-4043) Improve IllegalArgumentException message in RelBuilder#field

["Ruben Q L (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CALCITE-4043?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ruben Q L updated CALCITE-4043:
-------------------------------
    Description: 
The {{RelBuilder#field}} method that creates a {{RexNode}} based on alias + fieldName throws an {{IllegalArgumentException}} if the corresponding field is not found:
{code}
  public RexNode field(int inputCount, String alias, String fieldName) {
    ...
    throw new IllegalArgumentException("no aliased field found; fields are: " + fields);
  }
{code}

However, the exception message does not include the requested {{alias}} & {{fieldName}}, which is relevant information, definitively useful for troubleshooting.
