laravel remove data

Abstract:

Laravel is a popular PHP development framework suitable for building web applications. Sometimes, we need to delete some data in the database, which requires the use of the Laravel database query builder.

In this article, we will explain how to use the Laravel database query builder to cull data.

Text:

In Laravel, there are many ways to delete data. We can use Eloquent Model (ORM) to delete records or we can use Query Builder to execute SQL queries to delete records from the database.

In this article, we will use Query Builder to cull data.

First, let's assume we have a table called "users" (containing id, name and email fields).

Now, we need to remove the records with id equal to 1. We can use the following code:

DB::table('users')->where('id', '=', 1)->delete();

Here, we use the DB Facade to select the table to query, and use the where() method to limit which records to exclude. The delete() method is used to delete records from the database.

If we want to delete all records in the table, we can use the truncate() method. This method will delete the entire table and reset the auto-increment ID to 1. Here is an example of how to use the truncate() method:

DB::table('users')->truncate();

In this case, we are not filtering any records. Therefore, all records in the entire table will be eliminated.

If we need to delete records in the table but want to keep the table itself, we can use the drop() method. This method will delete the entire table, not just the records. Here is an example of how to use drop() method:

Schema::drop('users');

Here, we use Schema Facade to select the table to be deleted and use drop() method to delete the table.

Conclusion:

Laravel’s Query Builder is a very useful tool that allows us to easily cull data from the database. In this article, we covered how to cull data using the Laravel database query builder. Now you can easily delete records in your Laravel application.
