Assuming you're using ECPG, there are a couple of examples in the
documentation, e.g.,

http://www.postgresql.org/docs/8.3/static/ecpg-commands.html
(see Select using cursors:

http://www.postgresql.org/docs/8.3/static/ecpg-variables.html#AEN33442

The essence is you DECLARE the cursor, OPEN it and then FETCH rows in
some kind of loop, and finish by CLOSE cursor. To exit the loop, you
can check sqlca.sqlcode for 100 (NOT FOUND) or a SQLSTATE of 02000.
