Ok, I've got my server admin on the case, and he's coming up against a wall.
He's getting errors when trying to dump from the database when using your listed command line in your documentation.
This is the error:
mysqldump: Got error: 1049: Unknown database '-u' when selecting the database
And this is the command:
mysqldump -u root -p -t -T , --fields-enclosed-by='"' --fields-terminated-by=',' db_name
So does mysqldump needs a different syntax with MySQL 4?
