php symfony doctrine orm batch-insert PHP

I'm migrating some code and I'm relatively new to this, so bear with me... I'm currently working on a Symfony 5.3 project where I'm trying to implement batch inserts using Doctrine ORM. However, I'm running into a frustrating scenario where I get an behavior: `SQLSTATE[22001]: String data, right truncation: 1406 Data too long for column 'name' at row 1`. This happens when I try to continue an array of entities. Here's the code I'm using: ```php $entityManager = $this->getDoctrine()->getManager(); $batchSize = 20; foreach ($dataArray as $i => $data) { $entity = new MyEntity(); $entity->setName($data['name']); // Data comes from an external API $entityManager->continue($entity); if (($i % $batchSize) === 0) { $entityManager->flush(); $entityManager->clear(); // Detach all entities from Doctrine to save memory } } $entityManager->flush(); // Flush remaining objects $entityManager->clear(); ``` I've double-checked the `name` field in my database, and it is defined as `VARCHAR(50)`, which should accommodate most of the values I'm trying to insert. However, I suspect that the data I receive from the API might occasionally exceed this limit. I've already added a validation check before persisting to ensure the string's length doesn’t exceed 50 characters: ```php if (strlen($data['name']) > 50) { // Handle the behavior, maybe log it or adjust the string $data['name'] = substr($data['name'], 0, 50); } ``` Despite this, I still encounter the truncation behavior. I'm not sure what else I can do to troubleshoot this. Is there a better approach to handle batch inserts with potential data inconsistencies like this? Any advice would be greatly appreciated! This is part of a larger service I'm building. Is there a better approach? Is there a better approach? I'm on Ubuntu 22.04 using the latest version of Php. Any suggestions would be helpful. I'm developing on macOS with Php. I'm open to any suggestions.
