http://www.doctrine-project.org/jira This file is an XML representation of an issue en-us 5.2.7 850 21-02-2013 http://www.doctrine-project.org/jira/browse/DDC-1716 Doctrine 2 - ORM <p>It is too hard handle rows duplication now. As adviced here <a href="http://stackoverflow.com/questions/3967226/checking-for-duplicate-keys-with-doctrine-2" class="external-link">http://stackoverflow.com/questions/3967226/checking-for-duplicate-keys-with-doctrine-2</a> we should catch \PDOException with code 23000. This is bad behavior.</p> <p>So I propose:<br/> a. Add DuplicateRowException wich will throwed by flush method (maybe wrapped PDOException) with method "getDuplicatedProperties" (based on sql error description parsing + mapping)<br/> b. Add method findOneOrCreate (hello, Propel!) or updateIfExists to ObjectInterface, EntityManager<br/> c. Combine a, b</p> DDC-1716

Better unique constraints handling or even updateIfExists/findOneOrCreate

New Feature Minor Open Unresolved All Benjamin Eberlei Konstantin Mon, 19 Mar 2012 21:11:04 +0000 Thu, 19 Apr 2012 09:15:57 +0000 2.2.1 ORM 5 2 <p>I don't think it should be limited to the flush method, however, as this can occur with "custom" queries also. It would be ideal if the errors being generated can be much more easily (read: standardized) caught or read. </p> <p>I'm in favor of letting the database handle integrity checks, and not run a query to decide wether or not the update or insert queries will violate. Hence the desire to handle this more gracefully.</p> <p>The DBAL statement class (<a href="https://github.com/doctrine/dbal/blob/master/lib/Doctrine/DBAL/Statement.php" class="external-link">https://github.com/doctrine/dbal/blob/master/lib/Doctrine/DBAL/Statement.php</a>) has and execute method which might be a good place to catch and convert the generic PDOExceptions by wrapping the line</p> <p>$stmt = $this-&gt;stmt-&gt;execute($params);</p> <p>in a try/catch statement which then calls some kind of PDOException to Doctrine Exception method</p>
