Third class of the CodeIgniter course, in which we will see how the Query Builder works, which will help us to connect with databases.
3 – Query Builder in CodeIgniter
In this third class we will analyze what Query Builder is and how we can connect to any SQL database and make requests from CodeIgniter.
We will see how in reality it is still an abstraction layer, which will allow us to carry out complex queries to SQL databases in a simple way.
As you can see, Query Builder is not only that abstraction layer that we discussed, but we can also migrate our MySQL database to another engine, such as MariaDB or Oracle, without having to make major changes 🙂
So, we recommend you do the same and try to connect to a database, to confirm that everything works perfectly, because in the next class we will see the first of the three aspects that this framework has: The model.
Doubts or questions? You already know, you can send them to the intranet support form, and Luis will be delighted to assist you 🙂
