Creates a new Query object.

use Doctrine\ORM\EntityManager; // Retrieve the EntityManager instance $entityManager = ... // Create a Query object to retrieve all records from the 'users' table $query = $entityManager->createQuery('SELECT u FROM App\Entity\User u'); // Execute the query and retrieve the results $users = $query->getResult();
use Doctrine\ORM\EntityManager; // Retrieve the EntityManager instance $entityManager = ... // Create a Query object to retrieve all records from the 'users' table where the email address is 'example@example.com' $query = $entityManager->createQuery('SELECT u FROM App\Entity\User u WHERE u.email = :email'); $query->setParameter('email', 'example@example.com'); // Execute the query and retrieve the results $users = $query->getResult();This example shows how the createQuery method can be used to retrieve records based on a condition (in this case, where the email address is 'example@example.com'). The WHERE clause specifies the condition, and the setParameter method is used to provide a value for the placeholder in the query. In both examples, the Doctrine ORM library is used to manage database operations, and specifically the createQuery method is used to create and execute database queries.
