----------------------------------
I'm sorry to disturb you again. I do not get what you mean...
I tried to use RelBuilder.field("a", "a") or RelBuilder.field("a", "f0"), but
it throws {{no relation with alias 'a'; aliases are: [_DataSetTable_0]}}. And I
debug into {{field(String, String)}} and find that the {{stack.peek}} returns a
LogicalTableScan (the stack size is 1), not a Project.
My question is how can I refer to the field using the alias name, after using
an AS ?
I have been confused that why these code exist L788~L799 [1] ? It seems
duplicate with the following codes.

> RelBuilder does not translate identity projects even if they rename fields
