When using a MySQL database, you often need to back up and restore the database, and it is very convenient to export sql file backup and directly perform sql file recovery.

How to export and import sql files from a MySQL database through the cmd command?

Export 1. Export database

Contains data objects and data

Mysqldump-hhostname-uusername-ppassword databasename > / home/justin/databasename.sql II. Export database table structure

Only database table structure

Mysqldump-hhostname-uusername-ppassword-d databasename > / home/justin/databasename.sql III. Export stored procedures and functions

1. Query stored procedures and functions in the database

Method 1:

Select `name` from mysql.proc where db = 'databasename' and `type` =' PROCEDURE';-- stored procedure select `name` from mysql.proc where db = 'databasename' and `type` =' FUNCTION';-- function

Method 2:
