Oracle.ManagedDataAccess.EntityFramework – ORA-01918:用户’dbo’不存在

前端之家收集整理的这篇文章主要介绍了Oracle.ManagedDataAccess.EntityFramework – ORA-01918:用户’dbo’不存在前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我正在尝试使用Oracle.ManagedDataAccess 6.121.1.0提供程序实现代码第一次迁移,但是根本没有成功。

当我收到ORA代码时,我假设连接已成功打开。但是迁移是失败的,因为可能,提供程序表现为sql Server,而不是Oracle。我认为这是托盘使用“dbo”作为默认模式。

这是我的web.config设置:

<configuration>
  <configSections>
   <section name="entityFramework"
             type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection,EntityFramework,Version=6.0.0.0,Culture=neutral,PublicKeyToken=b77a5c561934e089"
             requirePermission="false" />
    <section name="Oracle.ManagedDataAccess.Client"
             type="OracleInternal.Common.ODPMSectionHandler,Oracle.ManagedDataAccess,Version=4.121.1.0,PublicKeyToken=89b483f429c47342" />
  </configSections>
  <entityFramework>
    <contexts>
      <context type="MyProject.Context.MainContext,MyProject.Context">
        <databaseInitializer type="MyProject.Context.Config.ContextInitializer,MyProject.Context" />
      </context>
    </contexts>
    <defaultConnectionFactory type="Oracle.ManagedDataAccess.Client.OracleClientFactory,Oracle.ManagedDataAccess" />    
    <providers>    
      <provider invariantName="Oracle.ManagedDataAccess.Client" 
                type="Oracle.ManagedDataAccess.EntityFramework.EFOracleProviderServices,Oracle.ManagedDataAccess.EntityFramework,Version=6.121.1.0,PublicKeyToken=89b483f429c47342" />
    </providers>
  </entityFramework>
  <system.data>
    <DbProviderFactories>
      <remove invariant="Oracle.ManagedDataAccess.Client" />
      <add name="ODP.NET,Managed Driver"
           invariant="Oracle.ManagedDataAccess.Client"
           description="Oracle Data Provider for .NET,Managed Driver"
           type="Oracle.ManagedDataAccess.Client.OracleClientFactory,PublicKeyToken=89b483f429c47342" />
    </DbProviderFactories>
  </system.data>
  <connectionStrings>
    <add name="MainContext"
         providerName="Oracle.ManagedDataAccess.Client"
         connectionString="Data Source=OracleServer:1521/BRSYSDS;User ID=USER;Password=PASSWORD;" />
  </connectionStrings>
  <!-- other settings -->
</configuration>

这里Stacktrace:

我也有同样的问题,并由Thiago Lunardi的回应解决。谢谢。我没有足够的声誉来表决你的回应。在这里提到,在UPPERCASE中设置我的模式名后,我成功了。

将其放在您的新的dbContext类的上下文文件中,如下所示:

public partial class MyAppContext : DbContext
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    modelBuilder.HasDefaultSchema("UPPERCASE_SCHEMA_NAME");
