【问题描述】：

我要做的只是查询一个视图，但我收到以下错误：

数据库“ELITEPROD”中的 CREATE TABLE 权限被拒绝

我正在使用实体框架编写 ASP.NET MVC5。这是我正在运行的代码：

string sql = @"SELECT ref.*, sts.[IMPORT_STATUS]
               FROM [ELITEPROD].[dbo].[SPEECH_PSYCH_WRITER] AS ref
               LEFT JOIN dbo.SPEECH_PSYCH_IMPORT_STATUS AS sts 
               ON sts.REQUEST_ID = ref.REFERRAL_ID
               WHERE REFERRAL_TYPE = @referType AND REFERRAL_CONTACT = @username 
               AND (sts.[IMPORT_STATUS] IS NULL OR sts.[IMPORT_STATUS] <> '');";

var referrals = eLite.Database.SqlQuery<Referral>(sql,
    new SqlParameter("@referType", referType),
    new SqlParameter("@username", username)
).ToList();

在 web 配置文件中，我配置了 2 个数据库。此查询发生在第二个查询上。不是DefaultConnection。数据库没有内存不足，我也没有（故意）尝试创建表。有什么想法吗？

这是完整的错误：

【问题讨论】：

这能回答你的问题吗？ CREATE TABLE permission denied in database 'tempdb'

Similar question 问题是数据库实例内存不足。

另一个可能的欺骗目标：Listing table results in “CREATE TABLE permission denied in database” ASP.NET - MVC4

【参考方案1】：

您的调用堆栈通过

System.Data.Entity.Database.Create(DatabaseExistenceState existenceState) +218

这意味着您的目标数据库不存在或与您的模型不是最新的，并且 EF 正在尝试更新架构。

也许您的连接字符串是错误的，但无论如何您都应该提前创建/迁移数据库架构，而不是在启动时。

【讨论】：

或者：完全禁用 EF 迁移并使用 SSDT 手动执行。我发现在任何真正复杂的项目中，或者当我需要使用新的 SQL Server 功能（仍在等待临时表、索引视图、表分区和EF 中的窗口功能支持...)

【参考方案2】：

在 Models 文件夹中，我设置了 ELiteDbContext.cs 并且我有这个定义：

public DbSet<Referral> Referrals  get; set; 

由于这只是我正在查询的一个视图，并且永远不会写入它，我所要做的就是注释掉 DbSet 行，一切正常。

【讨论】：

尽管如此，当不优先工作时，turn off automatic migration 总是一个好主意。
