问题 I'm attempting to migrate a database from a windows to a linux host. Thanks! Ashley 回答1: You are not finding the the table names under linux mysql, coz its default is case-sensitive.

问题 I have a mysql dump with 5 databases and would like to know if there is a way to import just one of those (using mysqldump or other).
