WITH clause in insert statement?

Question

Hi,
Can I use a WITH clause in my insert select. Something like this:
with q as
      select a
           , b
        from tabc
insert into tab( volume_x, volume_y )
select sum( s.volume_x ), sum( s.volume_y )
  from (
         select q.a  volume_x
              , 0    volume_y
           from q
          where t.b = 'x'
         union all
         select 0
              , sum( q.a )
           from q
          where t.b = 'y' ) s??

Answer 1

Yes, but the WITH clause is part of the SELECT part of the insert:
SQL> create table tab (x number, y number);
Table created.
SQL> insert into tab(x, y)
  2  with v as (
  3     select 1 a, 2 b from dual union all
  4     select 3 a, 4 b from dual
  5  )
  6  select a, b
  7  from v
  8  /
2 rows created.cheers,
