Basic Syntax

The basic syntax for updating data with Doctrine 2 Query Builder is as follows:

$qb = $entityManager->createQueryBuilder();
$qb->update('MyEntity', 'e')
    ->set('e.field', ':value')
    ->where('e.id = :id')
    ->setParameter('value', $newValue)
    ->setParameter('id', $entityId)
    ->getQuery()
    ->execute();

This code selects the entity MyEntity and updates the field field with the new value $newValue where the entity ID is equal to $entityId.

Updating Multiple Fields

To update multiple fields in one query, simply add additional set() statements to the query:

$qb = $entityManager->createQueryBuilder();
$qb->update('MyEntity', 'e')
    ->set('e.field1', ':value1')
    ->set('e.field2', ':value2')
    ->where('e.id = :id')
    ->setParameter('value1', $newValue1)
    ->setParameter('value2', $newValue2)
    ->setParameter('id', $entityId)
    ->getQuery()
    ->execute();

Updating Multiple Rows

To update multiple rows based on a specific condition, you can use the andWhere() method to add additional conditions to the query:

$qb = $entityManager->createQueryBuilder();
$qb->update('MyEntity', 'e')
    ->set('e.field', ':value')
    ->where('e.condition = :condition')
    ->andWhere('e.otherCondition = :otherCondition')
    ->setParameter('value', $newValue)
    ->setParameter('condition', $condition)
    ->setParameter('otherCondition', $otherCondition)
    ->getQuery()
    ->execute();

This code updates the field of all MyEntity objects where condition and otherCondition are both true.

Conclusion

Updating data with Doctrine 2 Query Builder in PHP is a powerful tool that can help developers construct complex SQL queries with ease. By understanding the basic syntax and how to update multiple fields and rows, developers can create efficient and effective database interactions.
