Fixing MySQL replication after a faulty query

Today I run into an issue with MySQL replication that prevented updates from the master to appear on the slaves. When checking the slave status, MySQL reports:

Slave_IO_State: Waiting for master to send event
Slave_IO_Running: Yes
Slave_SQL_Running: No
Last_Error: Query caused different errors on master and slave.

Apparently, an error occurred on the master (like a query that was wrong) and that failed on the slave as well. But since the error messages differ (a bit) the replication was stuck on this query. Manual intervention is required to tell MySQL what to do next.

This is what I used to fix it:

mysql -p
STOP SLAVE;
SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1;
START SLAVE;

I logged in into MySQL (line 1), stopped the slave thread (line 2), skipped the one faulty query (line 3) and started the slave thread again (final line). The status now reports both a running IO and SQL thread.

mysql> show slave status\G

Output:

 Slave_IO_State: Waiting for master to send event
 Slave_IO_Running: Yes
 Slave_SQL_Running: Yes
