Doctrine manual transaction

Since we do not do any custom transaction demarcation in the above code, EntityManager#flush() will begin and commit/rollback a transaction. This behavior is made possible by the aggregation of the DML operations by the Doctrine ORM and is sufficient if all the data manipulation that is part of a unit of work happens through the domain model and thus the ORM.  · The ability to unwind a transaction depends upon the particular facts and circumstances of the transaction and the manner in which a transaction is unwound and documented. But where the requirements are met, the so-called “rescission doctrine” offers a potential avenue to unwind a transaction without tax consequences. The Doctrine_Transaction::rollback ($savepoint) rolls back a transaction to the named savepoint. Modifications that the current transaction made to rows after the savepoint was set are undone in the rollback. Mysql, for example, does not release the row locks that were stored in .

When you run that migration, what actually happens with some platforms is you get the updates inside an implicitly commited transaction, then the CREATE TABLE happens outside that transaction, and then there is an attempt to commit an non-existent transaction. Doctrine ORM is an object-relational mapper (ORM)for PHP + that provides transparent persistence for PHP objects. It uses the Data Mapperpattern at the heart, aiming for a complete separation of your domain/businesslogic from the persistence in a relational database management system. The benefit of Doctrine for the programmer is the ability to focuson the object-oriented business logic and worry about persistence onlyas a secondary problem. // Snippet for Symfony 2 application that uses Doctrine 2 to handle transactions // It uses the names of the objects/doctrine repositories from the Beta 4 Manual of Symfony 2. // Get the entity manager.
