Home -> Community -> Mailing Lists -> Oracle-L -> RE: frequent commit, example ??? HELP
Hi Andrea,
Don't do it! Adding commits makes the code more complex, much less efficient and risks
violating transactional
integrity. See http://www.ixora.com.au/newsletter/2001_09.htm#commits for a detailed
explanation of the problems.

Hi all,
Thank you all those for responding to the frequent commit question. So members suggested using count, and loop. May I have real example. (OK, I'm bad at pl/sql). Site table has 2 million rows, how to so a commit, let's say 5000 rows. Site_id is unique in site table. How does the counter fit in the following update sql?
update site a set a.site_code =
(select c.area_code
from site_location b,
area c where a.site_id = b.site_id and
c.area_id = b.area_id);
I put a counter is a sample code, and update runs 10 times! then commit, then runs another 10 times! then commit .... I must miss something. Please give me as mush detail as you can. Thank you so much!
Andrea
