We have a teradata table with around 200 million rows. Whenever users query this table, they would like to see the output ordered by 2 columns in that table.
When I looked into the EXPLAIN of the query with and without ORDER BY, the estimated time is shown same with high confidence (as the stats are rightly available). I was expecting the query with ORDER BY to give a longer time that the one without ORDER BY.
Any reason, why it wasn't that way..?
