In the event you develop unclustered indexes, you must get an index only approach with incredibly speedy success. If I try to remember the right way, the very best success are going to be in precisely the same purchase since the index you us on big_table_1, but I'm unsure.

After we make use of the Top rated operator in a question, the question optimizer may possibly decide on a distinct query prepare for a similar question than one particular with no Major clause.
The approach With all the Prime makes use of an index scan on t2 giving 20M rows, then nested loop joins 2 rows via an index seek on t1.Code, then applies the highest operator.
This may rely on Anything you mean by "finished". If "finished" indicates you start seeing some display on the gui, that doesn't essentially signify the query has accomplished executing.
This question fetches the best five workforce with the very best salaries. The Get BY statement is critical in this article; without the need of it, we wouldn’t be confident of obtaining the highest earners, only a random list of 5 staff.
