在学说上进行迁移时出错

Question

我正在尝试通过对刚刚创建的实体进行迁移来将表创建到 sql server 中，但是在执行查询时会引发异常：

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:迁移

  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

那么迁移的时候迁移：

$ php bin/console doctrine:migrations:migrate

}

提前致谢。

第一个解决方案：

我打开了SQL Server Management Studio，对三个查询一一进行了测试。前两个工作只是 find 但第三个失败了，所以我按照@sepupic 所说的做了，它工作了。

谁能解释一下为什么当我使用 maker-bundle 进行迁移时，以下查询：

$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”是一个保留字，所以我将这个类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，实际上您的对象是 'dbo.user.roles' 没有括号，所以你应该使用'user'作为你的表格的参数，而不是'[user]'

Answer 2

问题是 'user' 是 sql server 中的保留字，所以我将类重构为不同的名称，它从头到尾都工作得很好
