根据学说进行迁移时出错

Question

我正在尝试通过为我刚刚创建的实体进行迁移来将 table 创建到 sql 服务器中，但它在执行查询时抛出异常：

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，我创建了一个新的用户实体

我进行了迁移：

$ 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

然后迁移迁移的时候：

$ php bin/console doctrine:migrations:migrate

迁移文件如下所示：

}

提前致谢。

第一个解：

我打开了 SQL Server Management Studio 并一一测试了三个查询。前两个只找到了，但第三个失败了，所以我按照@sepupic 说的做了，它成功了。

有人可以解释一下为什么当我使用 maker-bundle 进行迁移时，查询如下：

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

没有显示 user 而不是 [user]?

最终解决方案 好像 'user' 是一个保留字，所以我将 class 重构为一个不同的名称，它从头到尾都工作得很好

Answer 1

您的代码应如下所示：

EXEC sp_addextendedproperty N'MS_Description', N'(DC2Type:json)', N'SCHEMA', 'dbo', N'TABLE', 'user', N'COLUMN', 'roles'

错误告诉您对象 'dbo.[user].roles' 不存在，实际上您的对象 'dbo.user.roles' 没有括号，因此您应该使用 'user' 作为 [=23] 的参数=]，不是 '[user]'

Answer 2

问题是 'user' 是 sql 服务器中的保留字，所以我将 class 重构为不同的名称，它从头到尾都运行良好
