4.0.18 does not support Unicode. The JDBC driver tries to set the UNICODE charset but can't because this mysql version cannot store Unicode data as a charset. If you used 4.1.1, which is alpha it supports the charset and correlations.
My suggestion is this. Store the blobs on NAS as UNICODE text. mySQL is now used a lookups to the blob data in a particular even hashed directory structure on the NAS device that holds the UTF-8 or UCS data. If this is not available to you, then use 4.1.1 and don't use subselects, that is the most unstable portion of this branch. > -----Original Message----- > From: news [mailto:[EMAIL PROTECTED] On Behalf Of Stormblade > Sent: Thursday, April 22, 2004 5:33 PM > To: [EMAIL PROTECTED] > Subject: My Unicode Woes - Plz Help!!! > > I'm posting this as a last ditch effort to get this working or at least > find out what's going on and perhaps get a workaround if one exists. > > Platform: Windows XP SP1 > Database: MySQL 4.0.18 > JDBC Drv: 3.0.11 > > History: > There is an existing website which uses ColdFusion/SQLServer.
