time taken for a query

[st2003]

Hello:

This is the query I use to determine top 10 sql's in my database..

select disk_reads, executions, disk_reads/executions, sql_text
from v$sql
where executions != 0
and rownum < 11
order by 3;

How would I conclude the time taken for each query after I run this.

Am I missing any more columns to choose?

------------------

In continuation to that, this is what I have in my statspack report as long running query result:

CPU Elapsd
Buffer Gets Executions Gets per Exec %Total Time (s) Time (s) Hash Value
--------------- ------------ -------------- ------ -------- --------- ----------
14,813,652 296 50,046.1 30.0 1038.63 4974.33 4009553613
SELECT T106.C1,T106.C1,C7,C13,C526870925,C536870921,C4,C53687092
3,C536870915,C536871012,C8,C536870991,C536870992,C536871085 FROM
T106 WHERE ((T106.C4 = 'CANAM_NY') AND (T106.C7 < 5)) ORDE
R BY 1 ASC


Can anyone, PLEASE decode the numbers: [not the select statement]
I mean, what is Elapsed time, CPU Elapsed time, exec etc.,

And from the above, how would we determine, what time it took for the query to run...


Thanks, ST2003
