SQL & PL/SQL

Dear all,

I have found an interesting tutorial about Oracle analytic functions on orafaq web site that I share with you:

hxxp://www.orafaq.com/node/55

I was curious to compare the performance of each query using analytic functions with the traditional methods (GROUP BY and self joins).

Is there any command to write in SQL*Plus in order to see the total amount of seconds or milliseconds elapsed once a query has been terminated?


Thanks in advance,
:)
