Hi, list friends:
I am reading oracle 9.2 performance planning manual, and see it says:
Today's date. SELECT SYSDATE FROM DUAL can account for over 60% of the
workload on a database.
{page 33 of that manual}
How to understand that words? And does it mean to get the sysdate from
application server rather than the db server? How to do it in the sql statement?
anyone have examples?
Regards
zhu chao
