Sequence in insert all

Question

Hi,
I'm using a sequence in INSERT ALL statement. I want to insert multiple rows using a sequence number which will be generating the unique values for my table. But as far as i know, Oracle treats all occurances of a seq.nextval as a single reference and all of them retains the same value and not different one. My query is as below.
insert all
into t1(c1, c2) values (seq_1.nextval, 'A')
into t1(c1, c2) values (seq_1.nextval, 'B')
select * from dual;
select * from t1;
C1     C2
8     A
8     B
Can some one tell me how can i have different values for each row in insert all statement?

Answer 1

Create a function:
SQL> create or replace
  2  function get_seq_1
  3  return number
  4  is
  5  v_ret number;
  6  begin
  7      select seq_1.nextval into v_ret from dual;
  8      return v_ret;
  9  end;
10  /
Function created.
SQL> insert all
  2  into t1(c1, c2) values (seq_1.nextval, 'A')
  3  into t1(c1, c2) values (seq_1.nextval, 'B')
  4  select * from dual;
2 rows created.
