Multitable insert problem with sequences

Question

Lets consider that I have the folowing configuration:
create table t1 (col number, col2 varchar2(100));
create table t2 (col number, col2 varchar2(100));
create sequence s;
I want to put the same sequence value into many tables with one multitable insert like:
insert all
into t1 (col, col2) values (a, 'dummy 1.1')
into t2 (col, col2) values (a, 'dummy 1.1')
into t2 (col, col2) values (a, 'dummy 1.2')
into t2 (col, col2) values (a, 'dummy 1.3')
select s.nextval as a from dual
I know that the previous statement is "impossible" (acording oracle documentation http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_9014.htm it is forbidden and issue "ORA-02287: sequence number not allowed here" exception)
Do you have any ideas how to workaround this?

Answer 1

SQL> insert all
  2  into t1 (col, col2) values (s.nextval, 'dummy 1.1')
  3  into t2 (col, col2) values (s.currval, 'dummy 1.1')
  4  into t2 (col, col2) values (s.currval, 'dummy 1.2')
  5  into t2 (col, col2) values (s.currval, 'dummy 1.3')
  6  select 1 from dual;
4 rows created.
SQL> select *from t1;
       COL COL2
         1 dummy 1.1
1 row selected.
SQL> select * from t2;
       COL COL2
         1 dummy 1.1
         1 dummy 1.2
         1 dummy 1.3
3 rows selected.
