cmd console:
First enter the bin directory where mysql is located, such as: cd C:\Program Files\MySQL\MySQL Server 5.5\bin
mysqldump –u root –p database [table name 1 table name 2..] > file path
For example: backup the datacenter database to c:\datacenter.sql
mysqldump –u root –p datacenter> c:\datacenter.sql
If you want to backup some tables of the database
mysqldump –u root –prot datacenter user > d:\aa.sql

If an error is reported: ERROR 1046 (3D000): No database selected
Then mysql first use the database name, and then execute the source command
