Re: error when using move, any suggestions? - Mailing list pgsql-jdbc

Hi Dave,

It works fine in psql:
blast=# begin;
BEGIN
blast=# declare test cursor for select id from region where
protein_database = 1;
SELECT
blast=# move forward 99 in test;
MOVE
blast=# fetch forward 2 in test;
   id
--------
 486175
 481881
(2 rows)

Is this a driver error?
Thanks for your reply
Cheers
Noel
