Declarative Query Configuration

The QueryConfig class provides a configuration-based alternative to the fluent builder API. It is covered in detail in the Query Builder page, under the Declarative Query Configuration section.

Quick Reference

use Derafu\Query\Config\QueryConfig;

// From an array.
$config = new QueryConfig([
    'table'   => 'products',
    'select'  => 'id, name, price',
    'where'   => 'category?=electronics',
    'orderBy' => ['price' => 'DESC'],
    'limit'   => 10,
]);
$result = $config->applyTo($queryBuilder)->execute();

// From a YAML file.
$config = QueryConfig::fromYamlFile('queries/product_report.yaml');

// From a JSON file.
$config = QueryConfig::fromJsonFile('queries/sales.json');

// Auto-detect format by extension.
$config = QueryConfig::fromFile('queries/report.yaml');
