[Zope-DB] Assign query result(nextval) to variable

[Israel Carr]

I have since come up with the following.  Is there a way to group all
queries into one transaction in a ZSQL method?  If I put a BEGIN; and
COMMIT; it doesn't perform them all as one transaction.  What is the
drawback of having multiple queries in one method?  

Thanks for previous help.

INSERT INTO project (proj_id)
  SELECT nextval('project_sequence_id_key'::text);

INSERT INTO memo (proj_id)
  SELECT nextval('project_sequence_id_key'::text);

INSERT INTO project
  (proj_leader, vend_id, vend_name, vend_leader, po_date)
VALUES
  (<dtml-sqlvar proj_leader type="string">,
   <dtml-sqlvar vend_id type="int">,
   <dtml-sqlvar vend_name type="string">,
   <dtml-sqlvar vend_leader type="string">,
   <dtml-sqlvar po_date type="string">
);

What you want to do is use currval('project_sequence_id_key') which will
give you the current value.
