我不知道如何导入SQL转储文件.如果不先在MySQL中创建数据库，我似乎无法导入数据库.
这是尚未创建database_name时显示的错误:
username = username of someone with access to the database on the original server.
database_name = name of database from the original server
$ mysql -u username -p -h localhost database_name < dumpfile.sql
Enter password:
ERROR 1049 (42000): Unknown database 'database_name'
如果我以root用户身份登录MySQL并创建数据库
mysql -u root
create database database_name;
create user username;# same username as the user from the database I got the dump from.
grant all privileges on database_name.* to username@"localhost" identified by 'password';
exit mysql
然后再次try 导入sql转储:
$ mysql -u username -p database_name < dumpfile.sql
Enter password:
ERROR 1007 (HY000) at line 21: Can't create database 'database_name'; database exists
我应该如何导入SQL转储文件？
