在学说上进行迁移时出错 [英] Error when making a migration on doctrine

问题描述

我试图通过对刚创建的实体进行迁移来在sql服务器中创建表，但是在执行查询时会抛出异常：

I'm trying to create a table into a sql server by making a migration for the entity I just created, but it throws an exception when executing the query:

SQLSTATE [42000, 15135]: [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Object is invalid. Extended properties are not permitted on 'dbo.[user].roles', or the object does not exist.

通过使用maker-bundle，我创建了一个新的User实体

By using maker-bundle I created a new User entity

我进行了迁移：

$ php bin /控制台make：migration

$ php bin/console make:migration

  Success!


 Next: Review the new migration "src/Migrations/Version20181121121145.php"
 Then: Run the migration with php bin/console doctrine:migrations:migrate
 See https://symfony.com/doc/current/bundles/DoctrineMigrationsBundle/index.html

然后迁移迁移时：

$ php bin/console doctrine:migrations:migrate

迁移文件如下：

namespace DoctrineMigrations;

use Doctrine\DBAL\Schema\Schema;
use Doctrine\Migrations\AbstractMigration;

/**

        $this->abortIf($this->connection->getDatabasePlatform()->getName() !== 'mssql', 'Migration can only be executed safely on \'mssql\'.');

        $this->addSql('CREATE TABLE [user] (id INT IDENTITY NOT NULL, username NVARCHAR(180) NOT NULL, roles VARCHAR(MAX) NOT NULL, password NVARCHAR(255) NOT NULL, email NVARCHAR(255) NOT NULL, PRIMARY KEY (id))');

    }

    public function down(Schema $schema) : void
    {
        // this down() migration is auto-generated, please modify it to your needs
        $this->abortIf($this->connection->getDatabasePlatform()->getName() !== 'mssql', 'Migration can only be executed safely on \'mssql\'.');

        $this->addSql('CREATE SCHEMA dbo');
        $this->addSql('DROP TABLE [user]');
    }
}

谢谢。

第一个解决方案：

我打开了SQL Server Management Studio，并逐个测试了三个查询。可以找到前两个，但是第三个失败，所以我按照@sepupic的说明进行了工作。

I opened SQL Server Management Studio and tested one by one the three queries. The first two worked just find but the third one failed, so I did what @sepupic said and it worked.

有人可以解释一下为什么我使用maker-bundle，查询如下：

Can somebody explain me why when I made the migration using the maker-bundle, the query below:

$this->addSql('EXEC sp_addextendedproperty N\'MS_Description\', N\'(DC2Type:json)\', N\'SCHEMA\', \'dbo\', N\'TABLE\', \'[user]\', N\'COLUMN\', roles');

不显示 user 而不是 [user] ？

最终解决方案
似乎用户是保留字，因此我将类重构为一个不同的名称，并且从头到尾都很好用

Final Solution It seems to be 'user' is a reserved word, so I refactored the class to a different name and it worked just fine from the beginning to the end

推荐答案

问题是用户是保留字在sql server中，所以我将类重构为其他名称，并且从头到尾都很好用

The problem is that 'user' is a reserved word in sql server, so I refactored the class to a different name and it worked just fine from the beginning to the end
