Laravel’s Eloquent ORM (Object-Relational Mapping) provides a powerful and expressive way to interact with your database. One common scenario in database queries is the need to retrieve records where a particular column matches any value from a given set. Laravel Eloquent makes this task straightforward using the “IN” query.

What is the “WhereIN” Query?

The “IN” query is a SQL clause that allows you to specify multiple values in a WHERE clause. It is particularly useful when you want to retrieve records that match any value from a given list.

In the context of Laravel Eloquent, the “IN” query is often used with the `whereIn` method to simplify the syntax and improve readability.

Using `whereIn` in Laravel Eloquent

Let’s dive into a practical example to illustrate how to use the “IN” query with Laravel Eloquent. Consider a scenario where you have a `posts` table, and you want to retrieve all posts where the `category_id` is in a specific set of categories.

$categories = [1, 3, 5, 7];

$posts = Post::whereIn(‘category_id’, $categories)->get();

In this example, `Post` is the Eloquent model representing the `posts` table. The `whereIn` method takes two parameters: the column name (`category_id`) and an array of values (`$categories`). It retrieves all records where the `category_id` is in the specified array.

Chaining Multiple Conditions

You can also chain multiple conditions with the “IN” query to create more complex queries. For instance, if you want to retrieve posts from specific categories and with a certain status, you can do the following:

$categories = [1, 3, 5, 7];
$status = ‘published’;

$posts = Post::whereIn(‘category_id’, $categories)
->where(‘status’, $status)

Here, we’ve added an additional `where` clause to filter posts based on their status.


The “IN” query in Laravel Eloquent provides a clean and efficient way to retrieve records matching any value from a given set. Whether you’re working with simple queries or chaining multiple conditions, the `whereIn` method simplifies the process and improves the readability of your code.

By leveraging the power of Eloquent, you can write expressive and concise queries, making database interactions a breeze in your Laravel applications.
