Mysql DB upgrade Error from 1.1.x to 1.4

[ralphmyers]

When I attempt to upgrade the zabbix DB to 1.4 I get the following error:
ERROR 1062 (23000) at line 125: Duplicate entry '1' for key 1

I am most likely not patching the db correctly so if someone has the command to do so that would be great. Here is the command that I have been using:
cat patch.sql |mysql zabbix -u [USERNAME] -p

The user has full access to the database, so I dont think its a permissions issue.

Thanks

It seems that you have more than one record in table 'config'. This shouldn't happen. You may safely leave only one record in the table and re-run upgrade script.

That did it. Thanks!
