Common source commands for Database Import

Go to the mysql Database Console,

For example, mysql-uroot-p

Mysql> use Database Name

Then run the source command. The following parameter is the script file (for example,. SQL used here)

Mysql> source/home/bak. SQL

Common options:
-- All-databases,-A: Back up all databases
-- Databases,-B: used to back up multiple databases. If this option is not available, mysqldump uses the first name parameter as the database name, followed by the table name. With this option, mysqldum treats each name as the database name.

-- Force,-f: continues the backup even if an SQL error is found.
-- Host = host_name,-h host_name: Backup host name. The default value is localhost.
-- No-data,-d: only export the table structure
-- Password [= password],-p [password]: password
-- Port = port_num,-P port_num: Specifies the port number for TCP/IP connection.
-- Quick,-q: quick export
-- Tables: overwrite the -- databases or-B option. The following parameters are treated as table names.
-- User = user_name,-u user_name: user Name
-- Xml,-X: export as an xml file
