In Laravel, constructing multiple WHERE clause queries using Eloquent provides a powerful way to retrieve data with precision. This guide demonstrates how to use Laravel Eloquent for creating such queries step by step.
Granular Wheres with Array
In Laravel 5.3 (and versions up to 7.x), you can utilize granular where
clauses passed as an array:
$query->where([
['column_1', '=', 'value_1'],
['column_2', '<>', 'value_2'],
[COLUMN, OPERATOR, VALUE],
// ...
]);
While this approach is available, using multiple where
calls might be more common.
Granular Wheres with Where and OrWhere
Since June 2014, Laravel allows passing an array to the where
method. If you want all the where
clauses to use the AND
operator, you can group them in an array:
$matchThese = ['field' => 'value', 'another_field' => 'another_value', ...];
// If you need another group of wheres as an alternative:
$orThose = ['yet_another_field' => 'yet_another_value', ...];
// Query with AND operator
$results = User::where($matchThese)->get();
// Query with OR operator
$results = User::where($matchThese)
->orWhere($orThose)
->get();
The resulting query will look like:
SELECT * FROM users
WHERE (field = value AND another_field = another_value AND ...)
OR (yet_another_field = yet_another_value AND ...)
This method provides flexibility in crafting complex queries using Laravel Eloquent.
Remember to adapt the column names, operators, and values to your specific use case.
Conclusion
By leveraging Laravel Eloquent's expressive syntax, you can efficiently construct multiple WHERE clause queries to retrieve data that meets specific criteria. Experiment with these techniques to enhance your Laravel development skills.
