RelBuilder#empty does not keep aliases

    XMLWordPrintableJSON

    Details

      Description

      RelBuilder#empty method "Creates a relational expression that reads from an input and throws all of the rows away... The default implementation creates a Values with the same specified row type as the input". However, even though the "original" row-type is kept, its aliases are lost, which can lead to issues when building a plan (especially because this method is used internally by other methods, e.g. by RelBuilder#filter with an "always false" filter).
