Something like this should do the trick, if I read your post correctly:

Code:
UPDATE phpbb_topics SET forum_id="5" WHERE topic_first_poster_name LIKE "%ozerway%" AND forum_id="4" ;

Note (edit): Keep in mind that in many forums, table values might be used across multiple tables; so please insure that you only need to update forum_id in (the) one table in phpbb (you are considering updating).

DBIx::SearchBuilder::Handle::mysql(3pm) 		User Contributed Perl Documentation		   DBIx::SearchBuilder::Handle::mysql(3pm)

NAME
DBIx::SearchBuilder::Handle::mysql - A mysql specific Handle object SYNOPSIS
DESCRIPTION
This module provides a subclass of DBIx::SearchBuilder::Handle that compensates for some of the idiosyncrasies of MySQL. METHODS
Insert Takes a table name as the first argument and assumes that the rest of the arguments are an array of key-value pairs to be inserted. If the insert succeeds, returns the id of the insert, otherwise, returns a Class::ReturnValue object with the error reported. SimpleUpdateFromSelect Customization of "SimpleUpdateFromSelect" in DBIx::SearchBuilder::Handle. Mysql doesn't support update with subqueries when those fetch data from the table that is updated. DatabaseVersion Returns the mysql version, trimming off any -foo identifier CaseSensitive Returns undef, since mysql's searches are not case sensitive by default SimpleDateTimeFunctions Returns hash reference with specific date time functions of this database for "DateTimeFunction" in DBIx::SearchBuilder::Handle. ConvertTimezoneFunction Custom implementation of "ConvertTimezoneFunction" in DBIx::SearchBuilder::Handle. Use the following query to get list of timezones: SELECT Name FROM mysql.time_zone_name; Read docs about keeping timezone data up to date: http://dev.mysql.com/doc/refman/5.5/en/time-zone-upgrades.html AUTHOR
