Open the sql file and comment out the line that tries to create the existing database and remove USE mydatabasename and try again

You can also create a database named  mydatabasename  and then try restoring it again   Create a new database using MySQL CLI   mysql -u username  -p password  CREATE DATABASE mydatabasename    Then try to restore your database   mysql -u username  -p password  mydatabase lt mydatabase sql

when u import database from workbench or other method  should be give same name as your dump to avoid this kind of error

If initially typed the name of the database incorrectly  Then did a Php artisan migrate  You will then receive an error message  Later even if fixed the name of the databese you need to turn off the server and restart server

I had the same issue  i run this command on command line and just like you i had added the     at the end  Removing it solved the issue  Instead of this  mysql -uroot -pmypassword mydatabase lt mydatabase sql    try this  mysql -uroot -pmypassword mydatabase lt mydatabase sql

If dump file contains   CREATE DATABASE mydatabasename  USE mydatabasename     You may just use in CLI   mysql -uroot    pmypassword  lt  mydatabase sql   It works

Create database which gave error as Unknown database  Login to mysql shell  sudo mysql -u root -p create database db name   Now try restoring database using  sql file  -p flag will ask for a sql user s password once command is executed  sudo mysql -u root -p db name  lt  db name sql

I solved because I have the same problem and I give you some clues   1 - As  eggyal comments  mydatabase    mydatabasename   So  check your database name  2 - if in your file  you want create database  you can t set database that you not create yet   mysql -uroot -pmypassword mydatabase lt mydatabase sql    change it for   mysql -uroot -pmypassword  lt mydatabase sql

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 lt mydatabase sql    Two options for you     Remove USE mydatabasename  in your dump  and keep using   mysql -uroot -pmypassword mydatabase lt mydatabase sql  Change your local database name to fit the one in your SQL dump  and use   mysql -uroot -pmypassword mydatabasename lt mydatabase sql

I found these lines in one of the  sql files   To connect with a manager that does not use port 3306  you must specify the port number    mysqli   new mysqli  127 0 0 0 1   user   password   database   3307      or  in procedural terms    mysqli   mysqli connect  127 0 0 0 1   user   password   database   3307       It resolved the error for me   So i will suggest must use port number while making connection to server to resolve the error 1049 unknown database

La Chi s answer works for me    You can view his her answer in the comment of zessx answer in this page  But I initially have a problem with it if you also do just tweak his her answer like this  mysql -h localhost -u root -p -D mydatabase  lt  mydatabase sql   Also I would suggest that in the mydatabase sql portion you include the direct location of it in your computer like  C  Users username desktop     Thank you
