SQL & PL/SQL

Hi,

For modifications, I have to extract data from one table and insert it in another one, after this I have to get the new id from the second table and place it in the first table.

More or less, it should be so:

For every record loop
select law_item from table_one;
insert law_item into table_two;
insert into table one(law_id) values(table_two_sequence.currval);
End loop;

I saw (and I tried) many thing on Internet... (as type, bulk collect...) but did not succeeded in it.
Does anybody have a solution ?

Thank you in advance from Belgium-)
