Doctrine Backuptables

Question

Doctrine 2에서 백업 테이블을 만들 수있는 방법이 있습니다.

XML을 가지고 있으며 매일 cron 작업으로 가져 오기를 원합니다. 처음에는 끝이 _new 인 새 스키마를 만듭니다.

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); 
} 

xml에서 데이터를 가져온 후. 그리고 모두 괜찮습니다, 나는 테이블

$dm = Doctrine\DBAL\DriverManager::getConnection($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(); 

하지만 난 다시 가져올 때, 나는 다음과 같은 오류가 이름을 바꿉니다. . . . . 당신이 테이블 접두어, 때문에 인덱스 이름 중복 문제를 가지고있는 것처럼 :(

사람이 내 실수를 알거나 백업 테이블을 실현하는 더 나은 아이디어가 있습니까?

Answer 1

이 보이는위한하지 접두사 인덱스를 않습니다 당신은 그 종류의 기능을 위해 다른 데이터베이스를 사용해야하며, 이후에 이름을 바꿀 수 있으며 열린 두 연결로 데이터를 동기화 할 수 있습니다.
