# Switch to EF Core Oracle Provider
|
|
|
|
This document explains how to switch to the **Oracle** database provider for **[the application startup template](Startup-Templates/Application.md)** which comes with SQL Server provider pre-configured.
|
|
|
|
## Replace the Volo.Abp.EntityFrameworkCore.SqlServer Package
|
|
|
|
`.EntityFrameworkCore` project in the solution depends on the [Volo.Abp.EntityFrameworkCore.SqlServer](https://www.nuget.org/packages/Volo.Abp.EntityFrameworkCore.SqlServer) NuGet package. Remove this package and add the same version of the [Volo.Abp.EntityFrameworkCore.Oracle](https://www.nuget.org/packages/Volo.Abp.EntityFrameworkCore.Oracle) package.
|
|
|
|
## Replace the Module Dependency
|
|
|
|
Find ***YourProjectName*EntityFrameworkCoreModule** class inside the `.EntityFrameworkCore` project, remove `typeof(AbpEntityFrameworkCoreSqlServerModule)` from the `DependsOn` attribute, add `typeof(AbpEntityFrameworkCoreOracleModule)`
|
|
|
|
Also replace `using Volo.Abp.EntityFrameworkCore.SqlServer;` with `using Volo.Abp.EntityFrameworkCore.Oracle;`.
|
|
|
|
## UseOracle()
|
|
|
|
Find `UseSqlServer()` calls in your solution, replace with `UseOracle()`. Check the following files:
|
|
|
|
* *YourProjectName*EntityFrameworkCoreModule.cs inside the `.EntityFrameworkCore` project.
|
|
* *YourProjectName*DbContextFactory.cs inside the `.EntityFrameworkCore` project.
|
|
|
|
|
|
In the `CreateDbContext()` method of the *YourProjectName*DbContextFactory.cs, replace the following code block
|
|
|
|
```csharp
|
|
var builder = new DbContextOptionsBuilder<YourProjectNameDbContext>()
|
|
.UseSqlServer(configuration.GetConnectionString("Default"));
|
|
```
|
|
|
|
with this one (just changes `UseSqlServer(...)` to `UseOracle(...)`)
|
|
```csharp
|
|
var builder = new DbContextOptionsBuilder<YourProjectNameDbContext>()
|
|
.UseOracle(configuration.GetConnectionString("Default"));
|
|
```
|
|
|
|
> Depending on your solution structure, you may find more code files need to be changed.
|
|
|
|
## Change the Connection Strings
|
|
|
|
Oracle connection strings are different than SQL Server connection strings. So, check all `appsettings.json` files in your solution and replace the connection strings inside them. See the [connectionstrings.com]( https://www.connectionstrings.com/oracle/ ) for details of Oracle connection string options.
|
|
|
|
You typically will change the `appsettings.json` inside the `.DbMigrator` and `.Web` projects, but it depends on your solution structure.
|
|
|
|
## Re-Generate the Migrations
|
|
|
|
The startup template uses [Entity Framework Core's Code First Migrations](https://docs.microsoft.com/en-us/ef/core/managing-schemas/migrations/) by default.
|
|
EF Core Migrations depend on the selected DBMS provider. Changing the DBMS provider, may not work with the existing migrations.
|
|
|
|
* Delete the `Migrations` folder under the `.EntityFrameworkCore` project and re-build the solution.
|
|
* Run `Add-Migration "Initial"` on the Package Manager Console window (select the `.DbMigrator` (or `.Web`) project as the startup project in the Solution Explorer and select the `.EntityFrameworkCore` project as the default project in the Package Manager Console).
|
|
|
|
This will scaffold a new migration for Oracle.
|
|
|
|
Run the `.DbMigrator` project to create the database, apply the changes and seed the initial data.
|
|
|
|
## Run the Application
|
|
|
|
It is ready. Just run the application and enjoy coding.
