I can't get mysqldump to work. I typed mysql -uuser -ppassword sfg < sfgdump.sql The error is ERROR 2013 (HY000): Lost connection to MySQL server during query
phpninja <[EMAIL PROTECTED]> wrote: I prefer the mysqldump utility for transfering data. Its pretty fast (if your tables are not huge gigabytes in size).. and preserves you tables/data just as they were when you moved them. As far as I know, copying data on the filesystem level in mysql does not work. You cannot copy data files somewhere else and change the path and expect it to work. Use mysqldump or somthing similar to recreate your tables and move them.

While you can easily move MyISAM table files about amongst MySQL database directories (mind you stop the server and that MySQL access permissions won't follow), the same appears to not be true for InnoDB. I'm not sure what the best way to move or copy an InnoDB table or tables from one database to another is ... anyone? Dan murthy gandikota wrote: > Hi Dan > The table was never dropped.
