Suggestion required regarding BULK INSERT usage

Question

Hi All,
There is one table i.e., Markets and it contains 2 million records. I wanted inflate the same data for 10 times so, that count goes to 20 million records. I have written the following script to achieve this...
create or replace procedure mrkts_infltn(val number)
is
type markets_type is table of markets%rowtype;
l_markets markets_type;
begin
select * bulk collect into l_markets from markets;
for n in 1..val
loop
forall i in l_markets.first..l_markets.last
insert into markets values l_markets(i);
end loop;
end;
The above procedure is working fine...Now my question is, there is one column in markets table that is mrkt_id, I wanted to call sequence value for mrkt_id column (I don't want to insert the existng values for mrkt_id column). So, later we can easily delete the inflated data from the markets table by using sequnce value.
Any Help would be appreciated
Thanks,

Answer 1

Try selecting the sequence number in the select statement itself. So while select instead of doing select * from use Select <Seq_no.nextval>, <col1>, <col2> ... ;
Be careful that you select <Seq_no.nextval> instead of the id.
