3868 A table or view without alias appears more than once in FROM clause.
Explanation:
The same table or view appears more than once without NAMED phrase in the FROM clause of a SELECT statement. This causes ambiguity; the Teradata parser cannot resolve an unqualified column in select list since it can be found in more than one table/view in the FROM clause.
