In this post I will show you how to fix an error that appears in my thermal printer plugin that says: Error en el servidor: sql: no rows in result set.
This error says that there are no rows in the database, and you may be wondering what printing has to do with a database, so that is exactly what I will discuss in this post.
In this article about programming in the Go language (also known as Golang) we will see how to create a REST API that communicates through JSON, saving and displaying data from a MySQL / MariaDB database.
In the end we will have a REST API with Go using the 4 methods: POST, PUT, DELETE and GET using the Mux router. We are also going to implement the 4 operations of a database: insert, update, delete and select.
I will leave the full open source code at the end of the post.
