Home -> Community -> Mailing Lists -> Oracle-L -> RE: QUESTION ON RESTRICTING BULK COLLECT
Rajan,
For what it's worth I have never been able to get bulk collect to work on a large number of records restricting with recno. It was so painfully slow. I use it to bring small lookup tables into memory but I don't use it for cursor-driven programs, like data loads.
I've found that speed is OK (600,000 recs/hr) without bulk collect on the driving cursor, but using FORALL commits.
But if your question is, how can you pull the records in order with bulk collect, can't you do it with a subquery?
CURSOR c1 is
SELECT * FROM
( select * from table_a
order by col1);
OPEN c1;
fetch c1 bulk collect into ... limit rows;

Hi Folks,
I know this has been discussed before. As usual I
inherited a procedure which runs like a 'wool in the
oil bath'.It deals with 10 Million row table. I was
planning on using 'Bulk collect' feature. I knew bulk
collect runs 'amok' if you don't restrict the number
of rows you process. In my case rownumber may not work
because I need to bring in all the rows in sequesnce
of say 10000 in one bulk run so that I could process
all 10 Mil. I would greatly appreciate any ideas and
suggestions.
TIA.
BTW I am on 8.1.6.3
Regards,
RS
