Dear All,
I am using pgsql 7.2. The server always generate following warning message:
NOTICE: ROLLBACK: no transaction in progress

I would like to know how to get rid of such messages

This message indicates a problem with your query. You can only use the ROLLBACK command after starting a transaction with the BEGIN command.

Example:

good:

BEGIN
DELETE FROM table;
ROLLBACK;

bad:

DELETE FROM table;
ROLLBACK;

bad:

BEGIN;
DELETE FROM table;
COMMIT;
ROLLBACK;

bad:

BEGIN;
DELETE FROM table;
ROLLBACK;
ROLLBACK;
