Hi @maliming,

Thanks. So should we downgrade framework to lower version or using another library like devart?

Hi maliming,

I am trying to install abp suite version 3.3.2 to downgrade framework to net core 3.1. Can you help me fixing this error:

• You are attempting to install a preview release and did not use the --version option to specify the version.
• A package by this name was found, but it was not a .NET Core tool.
• The required NuGet feed cannot be accessed, perhaps because of an Internet connection problem.
• You mistyped the name of the tool.

Hello support team,

Oracle just release the Oracle EF Core 5 https://www.nuget.org/packages/Oracle.EntityFrameworkCore/5.21.1 Can you guide me on how to upgrade to this new package?

I am having the same problem with Oracle version 19c.xx. I created new solution from beginning using ABP Suite, no migration so I think the issue happens in framework.

@toan.nguyen are you also using Devart Oracle provider or the official Oracle provider?

I am using the Devart Oracle provider. The official Oracle provider haven't been integrated in the 4.2.1 yet, I'm waiting for the new version as you guys said it will be released in version 4.3.

@toan.nguyen are you also using Devart Oracle provider or the official Oracle provider?

@bhyatz I am using Devart.

Hhi maliming,

I am testing version 4.3-preview, I cannot find the option to connect to Oracle using Oracle Official package. Can you please check?

Regards, ToanNM.

• ABP Framework version: v4.3 Preview (RC1)

• DB provider: EF Core
• Tiered (MVC) or Identity Server Separated (Angular): yes / no
• Exception message and stack trace: An error occurred when executing host database seed
• Steps to reproduce the issue:
  • Change the Entity Framework from using SQL server to Using Oracle, official .net package
  • Run the DBMigrator project
  • Errors occurred as below image

• Open the Oracle PL/SQL Developer, browse created tables. It show error table/view does not exist

• We checked the database and can see that the table name created include the "" characters. Change the query to select * from "AbpBlobContainers" t include the "", can see the result.

I think that the issue is create the table with "" characters when creating the models. Please support.

Hi,

Did you re-create migration file?

Hi liangshiwei,

Yes. I created the migration files after change from useSQL to useOracle, also delete/re-created after errors occured did not solve the problem.
