migration from MySql 4.1 to MySql 5.0

[Migrated From Jforum.net]

I'm trying to migrate database from:
mysql Ver 14.7 Distrib 4.1.20, for redhat-linux-gnu (i386) using readline 4.3
to
mysql Ver 14.12 Distrib 5.0.37, for redhat-linux-gnu (i686) using readline 5.0

sql script migrate success.. encoding is correct..
but Jforum shows this:

com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: Unknown column 'forum_id' in 'field list'
at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:936)
at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:2941)

This can't be simple due a database version migration. There are problems with your JForum installation. It looks like you did't run some upgrade script when upgrading from an older version of JForum (or, when converting the table from one version of mysql to another, something happened that corrupted a table... hard to say)

it's funny but i install under FC7 MySQL 4.1 the same version as FC4 has.
I copy database files directly! from FC4, and copy tomcat with working copy of Jforum from FC4.
AND! I have the same exception

Hey Sae,

I am having the same problem... Have to migrate data from Mysql 4.1 to 5.0, and I'm getting an 'Unknown Column' Error, even though the column is defined in the table, and getMetadata also prints it. Plus, when I decided to not update this column, i.e. removed it from the query string, I still get an Error, saying this field not found.

Please let me know how you solved your problem
