Greatest and LEast cannot be used in Teradata. It does not
support those two clauses.
The only option is by using Case Stmnt as given above.
But then if the no.of Column increases(say 200) , its
tedious to write a complex Case stmnt and also it not a
optimised way of writing such queries.
HOping to see more better ans for this question. Also it is
a commonly repeated ques in most of the interviews.
