mysqldump 无法识别数据库名称？

Question

I am trying to export all of the tables of one of my databases "gamestore" located on localhost, to an xml file. I open command prompt as administrator and run this command:

C:\Program Files\MySQL\MySQL Server 8.0\bin>mysqldump --xml -u root -p gamestore > backup.xml;

I am prompted for a password, and I enter the correct one, but then I'm given an error:

mysqldump: Couldn't find table: ";"

I'm not sure what's causing this. Any advice?

If I reenter the command as:

C:\Program Files\MySQL\MySQL Server 8.0\bin>mysqldump --xml -u root -p --databases gamestore > backup.xml;

and enter the correct password, I still get an error:

mysqldump: Got error: 1049: Unknown database ';' when selecting the database

Answer 1

Just get rid of the trailing semicolon in your command.

During parsing of > backup.xml; the Windows command processor turns it into effectively

mysqldump --xml -u root -p --databases gamestore ;

with the redirection enabled, and MySQLDump gets confused about that now-extra semicolon.
