executed the query on pypmyadmin, also on mysql shell using : mysql -u root -p
it’s not executed because it returns nothing, both phpmyadmin and mysql shell.
the i run the same query on my xampp localhost on windows and it was executed successfully.
i follow this tutorial to build my webserver : http://www.servermom.org/build-ubuntu-server-a-complete-guide/
i’m sorry before, now the query was executed successfully. the problem is mysql use 100% of cpu, and then i’ve tried to index my table and it works. thanks for your help :)
