I am trying to restore database from .sql file , i have created the database in phpmyadmin and also using the create if not exist command in the .sql file which i am restoring to the database and both names of database are same in phpmyadmin and .sql file which is"mydatabase".

Here is the command which i am using to restore database.

Please help me how can i solve this issue. Thanks,

Answer 1

If dump file contains:

CREATE DATABASE mydatabasename; USE mydatabasename;  

You may just use in CLI:

mysql -uroot –pmypassword < mydatabase.sql 

It works.

Answer 2

Whatever the name of your dump file, it's the content which does matter.

You need to check your mydatabase.sql and find this line :

USE mydatabasename; 

This name does matter, and it's the one you must use in your command :

mysql -uroot -pmypassword mydatabasename<mydatabase.sql; 

Two options for you :

1. Remove USE mydatabasename; in your dump, and keep using :
   mysql -uroot -pmypassword mydatabase<mydatabase.sql;
2. Change your local database name to fit the one in your SQL dump, and use :
   mysql -uroot -pmypassword mydatabasename<mydatabase.sql;
