ORACLE UPDATING CHUNKS BIG TABLE

--Jeff Moden Row- Jeff Moden (5/9/2010) Gosh. my requirement is deleting entire table not just a subset of data oracle updating chunks big table. exchange partition for eda_log_item with partition eda_log_item_p. So basically a create a column in the temp table that has an integer for every 1000 rows, so 1,2,3 etc. Is create new table/rename method appropiate or can i do the following: 1. My idea is to create a partitioned table eda_log_item_p and exchange the maxvalue partition with non partitioned table eda_log_item(step 6), then split maxvalue partition and keep the maxvalue partition empty for next exchange. His T-sql blog is at http://beyondrelational. This ensures that the table is not locked oracle updating chunks big table. I need to remove more than million records. Then, you ll need to use a WHILE LOOP to control the whole thing. When I tried to delete data frrm this table, it takes almost 12-13 hours for that kind of data, which is awful. eda_log_item_p could have different index to speed up search 3.

So if I partition eda_log_item_p and exchange partition with eda_log_item, eda_log_item only use normal index, insertand delete from parent table with cascade could be faster. you don t say if you have a maintenance window (downtime) to do this offline. src = GL; the extra sequences should not be deleted from t2 if the t1. Do you think this approach is ok for OLTP enviroment. I have a table eda_log_item have huge amount of data every day needs housekeeping. It would step through numbers which represented the groups of 1000 and do set based updates of 1000 rows for each iteration of the While Loop. b) flip flop the tables (rename current to old, new to current) c) create table keep as select * from old where you still have all of the old audit information, just elsewhere. Let me make sure I understand what you are saying. ] but, my requirement is deleting entire table not just a subset of data. The main business table has one column I am updating. This table has two foriegn keys and many other constraints. [I am guessing it is doing full table scan on child tables while deleting].

create index on log table create index EITEM_ELOG_FK_I on EDA_LOG_ITEM (LOG_ID) / -- step 4. Followup   November 24, 2008 - 5:24 pm UTC just delete it, it ll be inefficient but since no planning or design took place, there is not much you can do until it is designed to be efficient. If transaction date moves to next month then some delete statements should NOT HAPPEN.quest resource updating agent service.
. Suppose you want to update a column with the value 0, if it that column contains negative value. This table has reference to two tables and about 5 tables refer to this table. Thanks and regards I hate your code, can we fix it. Let us also assume that there are over 2 million row in that column that has a negative value. The counter in the WHILE LOOP will keep track of which groups you ll update.
