How to Combine WHERE Clauses with OR and AND in Laravel Eloquent?

Combining WHERE Clauses with OR and AND in Laravel Eloquent Query

When formulating complex database queries, it's often necessary to combine WHERE clauses with both OR and AND operators. This can be achieved in Laravel Eloquent using logical grouping.

Example:

Consider the query:

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

Solution:

To construct this query using Laravel Eloquent, follow these steps:

1. Create an anonymous query using the where method.
2. Within the inner query, use the orWhere method to combine OR conditions.
3. Create another nested anonymous query to define the AND conditions.

The resulting 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);
});

Note:

While using raw SQL is an option for more complex queries, it's generally recommended to use Eloquent to maintain readability and take advantage of Eloquent's query builder features.
