mysql - mysqldump error: Got packet bigger than max_allowed_packet' -

my application download mails on imap , stores them in mysql database. before supporting mails size upto 10 mb , hence 'mediumtext' column store mail service content enough. need back upwards mails upto 30mb. changed datatype column 'largetext'. yesterday mail service size 25 mb stored. after whenever execute mysqldump command throws error:

mysqldump: error 2020: got packet bigger 'max_allowed_packet' bytes when dumping table `ib_mailbox_backup` @ row: 3369

row 3369 contains 25 mb mail.

in mysql config increased 'max_allowed_packet' 64m 512m , still fails same error. executing mysqldump command on same machine mysql server running. how solve this?

you can add together --max_allowed_packet=512m mysqldump command. or add together max_allowed_packet=512m [mysqldump] section of my.cnf (thanks @varun)

mysql mysqldump

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
