Hi all
I'm new to teradata I want to confirm about the order priority of the execution of the query.
Sample query
Select top n x_column, y_column, z_column from table_abc order by x_column desc;

Whether the query fetch top n records at first and then execute order by or else order by execut first and then if fetches top n records..
Thanks in advance..
