原则备份 [英] Doctrine Backuptables
本文介绍了原则备份的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个XML，希望每天都用cron作业导入它。
首先我创建一个结束_new的新模式。
if（$ newTables）{
$ tablePastfix = new \DoctrineExtensions\TablePastfix（'_ new'）;
$ evm-> addEventListener（\Doctrine\ORM\Events :: loadClassMetadata，$ tablePastfix）;
}
$ entityManager = \Doctrine\ORM\EntityManager :: create（$ conn，$ config，$ evm）;
if（$ newTables）{
$ tool = new \Doctrine\ORM\Tools\SchemaTool（$ entityManager）;
$ classes = array（
$ entityManager-> getClassMetadata（'MyClasses'），
$ entityManager-> getClassMetadata（'MyClasses'），
$ entityManager-> getClassMetadata（'MyClasses'），
）;
$ tool-> createSchema（$ classes）;
}
之后我从xml导入数据。
没关系，我重命名表
$ dm = Doctrine\DBAL\DriverManager :: getConnection （$康恩）;
$ sql =DROP TABLE`mytable_old`;;
$ stmt = $ dm-> query（$ sql）;
$ stmt-> execute（）;
$ dm = Doctrine\DBAL\DriverManager :: getConnection（$ conn）;
$ sql =ALTER TABLE`mytable` RENAME`mytable_old`;;
$ stmt = $ dm-> query（$ sql）;
$ stmt-> execute（）;
$ dm = Doctrine\DBAL\DriverManager :: getConnection（$ conn）;
$ sql =ALTER TABLE`mytable_new` RENAME`mytable`;;
$ stmt = $ dm-> query（$ sql）;
$ stmt-> execute（）;
但是当我想再次导入时，我会收到以下错误。 。 。 。 。 ：（

解决方案
看起来你有一个问题，请问有谁知道我的错误或有更好的想法因为... e的索引名称重复，前缀表不为它们前缀索引。您应该为这种功能使用不同的数据库，您可以重命名它或同步打开两个连接的数据。
is there any way to make Backup Tables in Doctrine 2.
I have an XML and want to import it every day with an cron job. First I create a new Schema with the end _new.
if ($newTables) {
$tablePastfix = new \DoctrineExtensions\TablePastfix('_new');
$evm->addEventListener(\Doctrine\ORM\Events::loadClassMetadata, $tablePastfix);
}
$entityManager = \Doctrine\ORM\EntityManager::create($conn, $config, $evm);
if ($newTables) {
$tool = new \Doctrine\ORM\Tools\SchemaTool($entityManager);
$classes = array (
$entityManager->getClassMetadata('MyClasses'),
$entityManager->getClassMetadata('MyClasses'),
$entityManager->getClassMetadata('MyClasses'),
);
$tool->createSchema($classes);
}
After it i import the data from xml. And is all okay, i rename the Tables
$dm = Doctrine\DBAL\DriverManager::getConnection($conn);
$sql = "DROP TABLE `mytable_old`;";
$stmt = $dm->query($sql);
$stmt->execute();
$dm = Doctrine\DBAL\DriverManager::getConnection($conn);
$sql = "ALTER TABLE `mytable` RENAME `mytable_old`;";
$stmt = $dm->query($sql);
$stmt->execute();
$dm = Doctrine\DBAL\DriverManager::getConnection($conn);
$sql = "ALTER TABLE `mytable_new` RENAME `mytable`;";
$stmt = $dm->query($sql);
$stmt->execute();
But when i want to import again, i get the following error . . . . . :(
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000]: General error: 1005 Can't create table 'databasename.#sql-220_87' (errno: 121)' in /Applications/MAMP/bin/php/php5.3.14/lib/php/Doctrine/ORM/Tools/ToolsException.php on line 33

Do anybody know my mistake or have an better idea to realize backup tables?
解决方案
it looks like you have an issue because of index name duplication, prefixing tables does not prefix indexes for them. You should use a different database for that kind of functionality, you can rename it afterwards or sync data with two connections opened.
