Question

我目前有一个Asp.net网站，为其所有提供商使用MySQL数据库。即时通讯使用默认的asp.net Web表单模板作为测试床，登录工作，注册工作，但当我尝试管理我的新帐户时，我收到此错误

Table 'trotski.usersopenauthaccounts' doesn't exist

尝试调用此函数时

Dim accounts = OpenAuth.GetAccountsForUser(User.Identity.Name)

（整个错误日志：）

Answer 1

Table 'trotski.usersopenauthaccounts' doesn't exist

数据库usersopenauthaccounts中的表trotski不存在，它是自解释的吗？检查它指向的数据库并确保该表存在。

Answer 2

堆栈跟踪表明您使用的是Visual Studio 2012以及entity framework和asp.net membership provider。我怀疑您使用的是SimpleMembership提供程序并使用了Visual Studio中的模板。

您可能在项目的某个位置有SimpleMemberShipInitializer类的实现。在此实现中，您可以找到：

WebSecurity.InitializeDatabaseConnection(
"DefaultConnection", "UserProfile", 
"UserId", "UserName", autoCreateTables: true
);

（在我的最新项目中，此代码位于InitializeSimpleMembershipAttribute.cs file）

内的filters文件夹中

注意最后一个名为autoCreateTables的参数。使用此参数，您应该能够让SimpleMemberShip Provider创建所需的表，如果它们确实缺失的话。
