我想首先使用PowerTools对代码进行逆向工程.当我从本地MS-sql数据库进行逆向工程时,它可以工作,但不能从Oracle DB中进行.我在输出控制台中收到以下错误：
System.Data.ProviderIncompatibleException: The provider did not return a ProviderManifestToken string. ---> Oracle.DataAccess.Client.OracleException: ORA-1005: null password given; logon denied at Oracle.DataAccess.Client.OracleException.HandleErrorHelper(Int32 errCode,OracleConnection conn,IntPtr opsErrCtx,OposqlValCtx* pOposqlValCtx,Object src,String procedure,Boolean bCheck) at Oracle.DataAccess.Client.OracleException.HandleError(Int32 errCode,Object src) at Oracle.DataAccess.Client.OracleConnection.Open() at Oracle.DataAccess.Client.EFOracleProviderServices.GetDbProviderManifestToken(DbConnection connection) at System.Data.Common.DbProviderServices.GetProviderManifestToken(DbConnection connection) --- End of inner exception stack trace --- at System.Data.Common.DbProviderServices.GetProviderManifestToken(DbConnection connection) at System.Data.Entity.Design.EntityStoreSchemaGenerator.GetProviderSchemaMetadataWorkspace(DbProviderServices providerServices,DbConnection providerConnection,Version targetEntityFrameworkVersion) at System.Data.Entity.Design.EntityStoreSchemaGenerator.CreateStoreSchemaConnection(String providerInvariantName,String connectionString,Version targetEntityFrameworkVersion) at System.Data.Entity.Design.SsdlGenerator.EntityStoreSchemaGeneratorDatabaseSchemaLoader.CreateStoreSchemaConnection(String providerInvariantName,Version& storeSchemaModelVersion) at System.Data.Entity.Design.EntityStoreSchemaGenerator..ctor(String providerInvariantName,String namespaceName) at Microsoft.DbContextPackage.Handlers.ReverseEngineerCodeFirstHandler.ReverseEngineerCodeFirst(Project project)
我可以通过右键单击项目>来正常生成EF文件.添加> ADO.NET实体数据模型>选择“从现有数据库”并按照向导的其余部分.我更喜欢powertools,原因有几个(主要是映射为.cs文件).使用Oracle时为什么不能进行逆向工程？ TIA
