I would like to know if we can insert 300 million records into an oracle table using a database link. The target table is inproduction and the source table is in development on different servers.The target table will be empty and have its indexes disabled before the insert. if this can be accomplished in less than 1 hour.

I want to know how we can insert more than 3 million records from one table to another table. Can we use Bulk collect and forall to insert the all data.Can we use create table tableB as select * from tableA; From the above which is one is performance wise good.

Please provide an update statement which would update deptno column of EMP table((based on) order by EMPNO) in for every 120 records incrementing by 1.(DeptNo to be incremented by 1,like 10 ,11 , 12 etc).
First 120 Records deptno should be 10,
Next 120 Records deptno should be 11, and so on.

View 2 Replies View RelatedOracle 11gI have a large table of 125 million records - t3_universe. This table never gets updated or altered once loaded, but holds data that we receive from a lead company. I need to select records from this large table that fit certain demographic criteria and insert those into a smaller table - T3_Leads - that will be updated with regard to when the lead is mailed and for other relevant information. select records from this 125 million record table to insert into the smaller table.
I have tried a variety of things - views, materialized views, direct insert into smaller table...I think I am probably missing other approaches. My current attempt has been to create a View using the query that selects the records as shown below. Then use a second query that inserts into T3_Leads from this View V_Market. This is very slow. Can I just use an Insert Into T3_Leads with this query - it did not seem to work with the WITH clause? My Index on the large table is t3_universe_composite and includes zip_code, address_key, household_key.
CREATE VIEW V_Market asWITH got_pairs AS ( SELECT /*+ INDEX_FFS(t3_universe t3_universe_composite) */ l.zip_code, l.zip_plus_4, l.p1_givenname, l.surname, l.address, l.city, l.state, l.household_key, l.hh_type as l_hh_type, l.address_key, l.narrowband_income, l.p1_ms, l.p1_gender, l.p1_exact_age, l.p1_personkey, e.hh_type as filler_data, 1.p1_seq_no, l.p2_seq_no , ROW_NUMBER () OVER ( PARTITION BY l.address_key ORDER BY l.hh_verification_date DESC ) AS r_num FROM t3_universe e JOIN t3_universe l ON l.address_key = e.address_key AND l.zip_code = e.zip_code AND l.p1_gender != e.p1_gender

I want to update a table 8 million records of a table which has 10 millions records, what could be the best strategy if the table has a BLOB column with 600GB worth of data. BLOB itself is 550GB. I am not updating the BLOB column. Usually with non-BLOB data i have tried doing "CREATE TABLE new_table as select <do the update "here"> from old_table;" method .
View 6 Replies View Relatedthe problem is: 2 tables - one with 2 million records, and the other with 8000 records.
i need to compare for each record in a table if there's a similar string on the other table.
i've created a procedure that does the following:
opens the first cursor (select col1,col2,col3,col4... from table 1)
loop
opens second cursor (select col1 from table 2)
loop
if utl_match(col1, table2.col1) > 80 then
insert col1,col2,col3,col4... into tableX
end if
close second cursor
close first cursor
the thing is that this procedure takes forever to end...about 8 days.
is it because im using the utl_match function? is there a way to speed this up?

For instance, if the incoming record is present in the target table I would update them in the target else I would simply insert. I have over one million records in my source while my target has 46 million records. The target table is partitioned based on calendar key. I implement this whole logic using Informatica.
