Free and open source schema versioning and migration tool made with .NET Core. Run migrations with plain SQL, arrange versions in ordinary folders and seed your data from CSV via stand-alone CLI (no CLR needed), Azure Pipelines, Docker or ASP.NET Core code. https://yuniql.io

yuniql

yuniql (yuu-nee-kel). Free and open source schema versioning and database migration engine made natively with .NET Core. Use plain SQL scripts, bulk import CSV, integrate CI/CD pipelines, zero runtime dependencies and works with windows and linux. Supports SqlServer, PostgreSql, MySql, and MariaDB.

<!--

Inspired by Evolutionary Database Design by Martin Fowler and Pramod Sadalage. -->

Working with CLI

Manage local db versions and run database migrations from your CLI tool. Perform local migration run or verify with uncommitted runs to test your scripts. Install yuniql CLI with Chocolatey or use alternative ways listed here https://yuniql.io/docs/install-yuniql

choco install yuniql --version=1.0.1

Run migrations for SQL Server

docker run -d -e "ACCEPT_EULA=Y" -e "[email protected]!" -p 1400:1433 -d mcr.microsoft.com/mssql/server:2017-latest
SETX YUNIQL_CONNECTION_STRING "Server=localhost,1400;Database=yuniqldb;User Id=SA;[email protected]!"

git clone https://github.com/rdagumampan/yuniql.git c:\temp\yuniql-cli
cd c:\temp\yuniql-cli\samples\basic-sqlserver-sample

yuniql run -a
yuniql list

Run migrations for PostgreSql, MySql and others

docker run -d -e POSTGRES_USER=sa -e [email protected]! -e POSTGRES_DB=yuniqldb -p 5432:5432 postgres
SETX YUNIQL_CONNECTION_STRING "Host=localhost;Port=5432;Username=sa;[email protected]!;Database=yuniqldb"

git clone https://github.com/rdagumampan/yuniql.git c:\temp\yuniql-cli
cd c:\temp\yuniql-cli\samples\basic-postgresql-sample

yuniql run -a --platform postgresql
yuniql list --platform postgresql

Working with Azure DevOps Pipelines Tasks

Run your database migration from Azure DevOps Pipelines. The tasks downloads package and cache it for later execution just like how Use .NET Core or Use Node tasks works. Find Yuniql on Azure DevOps MarketPlace. Developer guide is available here https://yuniql.io/docs/migrate-via-azure-devops-pipelines.

Working with Docker Container

Run your database migration thru a Docker container. This is specially helpful on Linux environments and CI/CD pipelines running on Linux Agents as it facilitates your migration without having to worry any local installations or runtime dependencies. Developer guide is available here https://yuniql.io/docs/migrate-via-docker-container.

git clone https://github.com/rdagumampan/yuniql.git c:\temp\yuniql-docker
cd c:\temp\yuniql-docker\samples\basic-sqlserver-sample

docker build -t sqlserver-example .
docker run sqlserver-example -c "<your-connection-string>" -a --platform sqlserver

Working with ASP.NET Core

Run your database migration when your ASP.NET Core host service starts up. This ensures that database is always at latest compatible state before operating the service. Applies to Worker and WebApp projects. Developer guide is available here https://yuniql.io/docs/migrate-via-aspnetcore-application.

dotnet add package Yuniql.AspNetCore

using Yuniql.AspNetCore;
...
...

//docker run -d -e "ACCEPT_EULA=Y" -e "[email protected]!" -p 1400:1433 -d mcr.microsoft.com/mssql/server:2017-latest
var traceService = new ConsoleTraceService { IsDebugEnabled = true };
app.UseYuniql(traceService, new Configuration
{
    WorkspacePath = Path.Combine(Environment.CurrentDirectory, "_db"),
    ConnectionString = "Server=localhost,1400;Database=yuniqldb;User Id=SA;[email protected]!",
    AutoCreateDatabase = true,
    Tokens = new List<KeyValuePair<string, string>> {
        new KeyValuePair<string, string>("VwColumnPrefix1","Vw1"),
        new KeyValuePair<string, string>("VwColumnPrefix2","Vw2"),
        new KeyValuePair<string, string>("VwColumnPrefix3","Vw3"),
        new KeyValuePair<string, string>("VwColumnPrefix4","Vw4")
    }
});

Working with Console Application

Run your database migration when Console App starts. Developer guide is available here https://yuniql.io/docs/migrate-via-netcore-console-application.

dotnet add package Yuniql.Core

using Yuniql.Core;
...
...

static void Main(string[] args)
{
    //docker run -d -e "ACCEPT_EULA=Y" -e "[email protected]!" -p 1400:1433 -d mcr.microsoft.com/mssql/server:2017-latest
    var traceService = new ConsoleTraceService { IsDebugEnabled = true };
    var configuration = new Configuration
    {
        WorkspacePath = Path.Combine(Environment.CurrentDirectory, "_db"),
        ConnectionString = "Server=localhost,1400;Database=yuniqldb;User Id=SA;[email protected]!",
        AutoCreateDatabase = true
    };

    var migrationServiceFactory = new MigrationServiceFactory(traceService);
    var migrationService = migrationServiceFactory.Create();
    migrationService.Initialize(configuration.ConnectionString);
    migrationService.Run(
        configuration.WorkspacePath,
        configuration.TargetVersion,
        configuration.AutoCreateDatabase,
        configuration.Tokens,
        configuration.VerifyOnly,
        configuration.BulkSeparator);
}
