我的问题是:
- 为什么 Symfony 中的 doctrine 迁移命令无法报告我在下面列出的 SQL 错误
- 我怎样才能让它报告此类错误,而不是看起来它已经成功了。
明确一点 - 我知道 SQL 本身失败的原因。这是最简单的部分。失败的无声本质就是问题所在。
我在 PHP 文件中有一个 Doctrine 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
第二条语句因唯一键约束而失败(例如“键‘PRIMARY’的重复条目‘6-3’”——这是一个复合键)但未报告错误。我知道它失败了,因为很明显最终语句永远不会运行,如果我手动运行有问题的语句,它就会失败。当我运行时:
./bin/console doctrine:migrations:migrate
在我的 Symfony 应用程序中,调用 doctrine 迁移代码,它报告:
$ ./bin/console doctrine:migrations:migrate
Application Migrations
WARNING! You are about to execute a database migration that could result in schema changes and data lost. Are you sure you wish to continue? (y/n)y

INSERT INTO `users_orgs` (`org_id`, `user_id`, `active`)

预期结果
我期待它报告错误。作为测试,我创建了一个带有主键的单列表。我试图插入一条记录,该记录会在迁移中生成唯一的约束冲突。当我执行迁移时, Doctrine 报告如下:
Migration 20160908112332 failed during Execution. Error An exception occurred while executing ' insert into FOO values (1)':
SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '1' for key 'PRIMARY'

我尝试过的
我在 google 和这里搜索了“silent doctrine failure”、“silent doctrine migration failure”,但没有看到任何内容。任何见解将不胜感激。
最佳答案
这与在一个查询中执行多个语句有关。
Doctrine 迁移 documentation说:
Internally the addSql call are passed to the
dbal executeQuery method
.
我尝试使用 executeQuery
执行多个语句,它的行为方式与您相同。 (我有不同的包版本,但只是补丁级别不同)。当我有多个语句时,它只会在第一个语句失败时抛出错误。
考虑这个例子:
/** @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}");
但是:
// ... same as above except for executeQuery
$connection->executeQuery("{$createTable}");
$connection->executeQuery("{$insert}");
$connection->executeQuery("{$insert}"); // <- duplicate key error is thrown
我想要达到的目的是为每个语句使用单独的 addSql()
语句。
[... 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 ...]
