MySQL Error for Blobs
I got an error while entering an BMP image of 1.7MB size in a mediumblob field through MS Access 2003 with MyODBC 3.51.12 on Windows XP SP2 also with MySQL Query Browser and Navicat GUI tool. Navicat returned the error as 'Got a packet bigger than Max_allowed_packet bytes'. What this means?. Access and Query browser simple gives error as MySQL has gone away? Why? please help. Also please give a solution if we have to insert images/Other Objects of size more than 1 MB what we have to do using ODBC driver with/without MS Access VB.net? Thanks CPK
Re: MySQL Error for Blobs
max_allowed_packet is the maximum size of a single SQL statement. It's a setting on the server, as well as for the mysql command line interface. See http://dev.mysql.com/doc/refman/5.0/en/packet-too-large.html I think 1 MB is the default; the maximum setting for MySQL 5 is 1 GB. You can adjust this setting in the server config files (my.cnf or my.ini). I do not know if you need to adjust anything in Navicat, ODBC, Query Browser or Access - sorry!

RE: MySQL Error for Blobs
When a query exceeds the size of the maximum allowed packet, mysqld closes the connection. It assumes something has gone wrong with the client. There are two max_allowed_packet variables, one for the server and one for the client. This is documented in section A.2.9 of the documentation http://www.mysql.org/doc/refman/4.1/en/packet-too-large.html Regards, Jerry Schwartz Global Information Incorporated 195 Farmington Ave. Farmington, CT 06032 860.674.8796 / FAX: 860.674.8341 -Original Message- From: C K [mailto:[EMAIL PROTECTED] Sent: Thursday, November 16, 2006 12:46 PM To: mysql@lists.mysql.com; [EMAIL PROTECTED] Subject: MySQL Error for Blobs I got an error while entering an BMP image of 1.7MB size in a mediumblob field through MS Access 2003 with MyODBC 3.51.12 on Windows XP SP2 also with MySQL Query Browser and Navicat GUI tool.
