mysql replication: show 'bad' query

Question

Is there a way to get MySQL to display the query that caused replication to stop? I have a DB with hundreds of identical tables, each of which has a trigger to update a related table. One of these is (apparently) not configured properly. I can't use the 'replication skip' trick as it will simply halt at the next write (and there are thousands).

If I can get the actual 'broken' query I can simply amend the table definition.

Suggestions?

Mysqld logs to syslog where you should see the error and the problematic statements logged. Apart from that, you can call SHOW SLAVE STATUS\G on the slave and look for the "Last_Error" column to get the same information. Additionally, you could use mysqlbinlog to take a look at the slave's relay log to see if there are more similar queries in the queue.
