hi friends... need help...
i am want to insert 500 million data from sTable to dTable such as
insert into dTable
select * from sTable
time taken : 20 mins
Note : there are no index or any constraint on both the tables.
database : oracle 10g
is there any fast way to insert bulk data ?
Twenty minutes for half a billion rows doesn't look that bad.
You may want to try append hint.
Also, if tables are partitioned you may want to use parallel processing; for a few partitions you may want to set degree of parallelism to the number of partitions.
