I've a MySQL 5.0.84 running in a Slackware 13.0 Staging server and wanted to copy a single table to another server which was built to use Ubuntu 14.04 OS for some other testing. I've taken a mysqldump of that table and copied to the testing server. I get the following error when I try to restore the dump file.

ERROR 1231 (42000):Variable 'character_set_client' can't be set to the value of 'NULL'

Please help me how to fix this error. Thanks!

I did some search in internet and fixed it finally.

Added the following text at the beginning of the mysqldump file and the restore was successful.

/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;

/*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */;
