带 LIMIT 的 Doctrine 更新查询

Question

我想用这样的 LIMIT 进行更新查询:

UPDATE anytable SET anycolumn = 'anyvalue' WHERE anothercolumn='anothervalue' LIMIT 20

这怎么可能用 Doctrine 2.1 实现？

Answer 1

我发现我必须从entityManager获取连接并调用executeUpdate:

$em->getConnection()->executeUpdate(
    "UPDATE anytable SET anycolumn = 'anyvalue'
     WHERE anothercolumn='anothervalue'
     LIMIT 20");

doctrine page about native queries说:

If you want to execute DELETE, UPDATE or INSERT statements the Native SQL API cannot be used and will probably throw errors. Use EntityManager#getConnection() to access the native database connection and call the executeUpdate() method for these queries.
