Hi,is there away to check with DB Link if one record exists/not exists in a remote database?
Something like...
SELECT item_id FROM TABLE A WHERE NOT EXISTS (SELECT 1 FROM TABLE B WHERE A.item_id=B.item_id)
Where Table A is on a Local machine and Table B is on a remote machine.
Thanks for any help on that.
Alex
