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
