Php 根据原则进行迁移时出错

我正试图通过对刚创建的实体进行迁移，将表创建到sql server中，但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 doctrine:migrations:migrate

                    Application Migrations

$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

然后，在迁移时：

$ php bin/console doctrine:migrations:migrate

不显示用户而显示[user]

最终解决方案

---

似乎“user”是一个保留字，因此我将该类重构为另一个名称，它从头到尾都运行良好

您的代码应该如下所示：

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，实际上您的对象是没有括号的“dbo..user.roles”，因此您应该使用

'user'

作为表的参数，而不是

'[user]'

问题是“user”是sql server中的保留字，因此，我将该类重构为一个不同的名称，它从头到尾都运行得很好

我按照问题底部的解释做了，它运行得很好。感谢@sepupic>>>有人能解释一下为什么我使用maker bundle进行迁移时，下面的查询是：din not show user而不是[user]？现在，当我尝试将数据插入它抛出的表中时：使用参数[“felipito”，“[]”执行“insert into user（username，roles，password，email）值（？，，，，，？）时发生异常“canelo123”fpcanelo@ati.cu“]：SQLSTATE[42000156]：[Microsoft][ODBC驱动程序17 for SQL Server][SQL Server]关键字“user”附近的语法不正确。无法准备SQLSTATE[420008180]：[Microsoft][ODBC驱动程序17 for SQL Server][SQL Server]语句。也许给出的解决方案与此有关@sepupicAnd对于INSERT，必须在括号中包含表名，因为它是关键字：INSERT INTO dbo。[用户]。。。
