How to Efficiently Build Complex OR and AND Queries in Laravel Eloquent?

Laravel Eloquent Query: Advanced OR and AND Conditions

In Laravel Eloquent queries, you may encounter scenarios where you need complex conditions involving OR and AND operators. To effectively handle such queries, Laravel provides a logical grouping feature that allows you to group multiple conditions logically.

Example:

Consider the following query:

WHERE (a = 1 OR b =1 ) AND (c = 1 OR d = 1)

Solution using Logical Grouping:

Laravel's Logical Grouping allows you to organize conditions into nested closures. For the above query, the code would look like this:

Model::where(function ($query) {
    $query->where('a', '=', 1)
          ->orWhere('b', '=', 1);
})
->where(function ($query) {
    $query->where('c', '=', 1)
          ->orWhere('d', '=', 1);
});

By nesting the conditions within closures, you can logically group them and achieve the desired query result.

Raw SQL Alternative:

While logical grouping is a recommended approach, you can also use raw SQL to handle complex queries. However, it is generally not preferred as it can lead to security vulnerabilities and make queries less readable.
