Check SQL Reference for "exception_clause" when creating Primary Key.
Could help to do what you need just using SQL (no PL/SQL).

Johann,
how about the following. what this does is, using the inner begin/end
block, catches when an insert would fail because of the PK failure and
ignores the error.
This is very quick and dirty - it will work fine if you are not working
with
a huge amount of data.
declare
cursor c1 is
select col1, col2
from some_table;
begin
for c1_rec in c1 loop
begin
insert into new_table(col1, col2)
values (c1_rec.col1, c1_rec.col2);
exception
when too_many_rows then
null;
end;
end loop;
end;
/
If you are talking about lots and lots of data, you could easily query
the
table you are inserting into, testing for the existence of the value you
are
attempting to insert. If you find it, skip the insert. Like this:
declare
rec_count number;
cursor c1 is
select col1, col2
from some_table;
begin
for c1_rec in c1 loop
begin
select count(*)
into rec_count
from new_table
where col1 = c1_rec.col1; -- this assumes that col1 is the pk!
if rec_count = 0 then
insert into new_table(col1, col2)
values (c1_rec.col1, c1_rec.col2);
end if;
exception
when too_many_rows then
null;
end;
end loop;
end;
/
Good Luck!

Looking for an a sample cursor routine to load a PK enabled table to
eliminate
any dupes from the load table.
