Hello,

In order to update an entry in your database, you need to use an UPDATE statement.

So let’s say that you have a table called users and a column called nickname and you want to change the entry for a user with nickname DigitalOcean to DO, you could do that with this query:

UPDATE users SET nickname = 'DO' WHERE nickname = 'DigitalOcean';

Of course, if you are unsure, always make a backup of your database first!

I would recommend having a look at this tutorial on how to install and also use a PostgreSQL database:

Hope that this helps! Regards, Bobby
