Hi again!
With a glass of Kopi Lanang - Dampit (http://www.malangtimes.com/baca/13954/20160820/132007/kopi-dampit-malang-salah-satu-kopi-terbaik-dunia/) to cure my longing for the atmosphere of coffee time in Aceh, and with great enthusiasm to finish writing my thesis (desperately need to be finished within two weeks :(), I've found an old note about working with MySQL, accidentally. I think it worth to be shared here. Here we go!
This time, we want to show unique value from a MySQL table with these values:
Let's solve this problem by creating a MySQL database and named it as "unique", and create a table "test" with above data and structure.
This is how I've done it using Linux terminal:
[root@adisun ~]# mysql -u root -p
Enter password:

Hopefully this post will be useful :)
