Question

我在Asp.Net MVC 4应用程序中使用Simple.Data for Oracle版本0.18.3.1。它适用于不在模式名称之前的表，但是当我尝试从必须在模式名称之前的表中获取数据时崩溃。我收到的错误是

"No matching table found, or insufficient permissions."

我需要执行的查询如下：

SELECT * FROM SchemaName.TableName

当我尝试在Oracle Sql Developer中执行它时，此查询正常工作。我得到了结果。但是在C＃中使用Simple.Data获得上述错误。我尝试了以下方法：

//BASE CLASS
public class BaseRepository
{
    protected dynamic DB { get; set; }
    public BaseRepository()
    {
        DB = Database.OpenNamedConnection("intranet_db");
    }
}

//Derived Class
public class EmployeeRepository : BaseRepository
{
    public List<Employee> GetEmployees()
    {                
        List<Employee> employees = DB.SchemaName.TableName.FindAllBy(JoinedOn:"2009-05-31");

        // I also have tried the following combinations as specified in documentations
        // DB.SchemaName["TableName"].FindAllBy(JoinedOn:"2009-05-31");
        // DB["SchemaName"].TableName.FindAllBy(JoinedOn:"2009-05-31");
        // DB["SchemaName"]["TableName"].FindAllBy(JoinedOn:"2009-05-31");

        return employees;
    }
}

但它不断抛出上述错误。

我做错了什么？

提前致谢。

使用模式名称访问Simple.Data表会引发错误
