In this Laravel course, we will learn about the Laravel Query Builder for Retrieving Data.
The Laravel Query Builder is a powerful tool for retrieving data from the database. It can be used to retrieve data from any table in the database, and it has many features that make it easy to use. It allows you to build complex queries with just a few lines of code. It's a powerful tool that will help you save time when building complex SQL queries or when you need to run multiple queries at the same time.
The first step is to have a database connection set up in the application's configuration file. The second step is to create a model class that extends Eloquent Model and implements the methods that are required by the interface. The third step is to define the query using Laravel Query Builder's fluent API, and finally, execute it by passing it into the find() method of the model class.
Laravel Query Builder was introduced in Laravel 5.5 to replace the old Eloquent query builder and it comes with some advantages over its predecessor:
- The query builder is more intuitive and expressive than before
- It can be used as a fluent API or as static methods
- A single method can be used for all types of queries
- The query builder does not need to be configured before use
When you need to retrieve data from tables in Laravel, the Query Builder is the way to go. It's a powerful tool that can be used for all kinds of queries, not just retrieving data. You can use it to update and delete records as well. The Query Builder is a great tool because it allows you to write SQL queries without having to learn SQL syntax or even know what SQL stands for!
