Question

我的问题是：

为什么Symfony中的doctrine migration命令无法报告我在下面列出的SQL错误
如何让它报告此类错误，而不是看起来已成功。

要明确 - 我知道为什么SQL本身会失败。这很容易。失败的沉默本质就是问题。

我在PHP文件中有一个学说迁移，如下所示：

[... boilerplate ...]

public function up(Schema $schema)
{
    $this->addSql(<<<SQL

    -- This runs fine
    CREATE TABLE [[redacted - this part runs fine]];

    -- This fails with a unique key constraint
    INSERT INTO `users_orgs` (`org_id`, `user_id`, `active`)
    SELECT `oid`, `uid`, 1 as `active` FROM `orgs`;

    -- Never gets here
    ALTER TABLE `orgs` CHANGE `uid` `primary_user_id` int(11) unsigned DEFAULT NULL;

SQL
    );
}

[... boilerplate ...]

实际结果

由于一个独特的键约束（例如＆＃34;重复输入＆＃39; 6-3＆＃39;用于键＆＃39; PRIMARY＆＃39;＆＃39; - 它＆＃39;复合键）但未报告错误。我知道它失败了，因为它很清楚最后的语句永远不会运行，如果我手动运行违规语句，它就会失败。我跑的时候：

./bin/console doctrine:migrations:migrate

从我的Symfony应用程序中调用doctrine迁移代码，它报告：

$ ./bin/console doctrine:migrations:migrate

                Application Migrations

预期结果

我希望它报告错误。作为测试，我创建了一个带有主键的单列表。我尝试插入一条记录，该记录会在迁移中生成唯一的约束违规。当我执行迁移时，学说报告了这个：

Migration 20160908112332 failed during Execution. Error An exception occurred while executing '        insert into FOO values (1)':

它将与在一个查询中执行多个语句有关。

Doctrine migrations documentation说：

在内部，addSql调用将传递给executeQuery。

我尝试用/** @var \Doctrine\DBAL\Connection $connection */ $connection = $this->getDoctrine()->getConnection(); $createTable = "CREATE TABLE test (org_id int not null, user_id int not null, PRIMARY KEY(org_id, user_id));"; $insert = "INSERT INTO test (org_id, user_id) VALUES (1, 1);"; // this will create the table (if doesn't exist) and add a record, the second insert silently fails. $connection->executeQuery("{$createTable}{$insert}{$insert}");执行多个语句，其行为方式与您相同。（我有不同的软件包版本，但只是补丁级别不同）。当我有多个语句时，如果第一个语句失败，它只会抛出一个错误。

考虑这个例子：

// ... same as above except for executeQuery
$connection->executeQuery("{$createTable}");
$connection->executeQuery("{$insert}");
$connection->executeQuery("{$insert}"); // <- duplicate key error is thrown

可是：

addSql()

我想要达到的目的是为每个陈述使用单独的[... boilerplate ...] public function up(Schema $schema) { $this->addSql("CREATE TABLE [[redacted - this part runs fine]];"); $this->addSql("INSERT INTO `users_orgs` (`org_id`, `user_id`, `active`) SELECT `oid`, `uid`, 1 as `active` FROM `orgs`;"); $this->addSql("ALTER TABLE `orgs` CHANGE `uid` `primary_user_id` int(11) unsigned DEFAULT NULL;"); } [... boilerplate ...]语句。
