Info

This Project includes most of the changes from all forks on GitHub!

But has also a few changes:

  • SQLite support is better (Schema Reading, multiple Primary Keys, and much more)
  • Remove direct References to the Dataproviders
  • Dump Indexes from SQLServer
  • Different Migration Scopes in one Database

NuGet

https://www.nuget.org/packages/DotNetProjects.Migrator/

Introduction

This project is a fork of "ye olde trusty" Migrator.Net - the original project can be found here on google code, and has since moved to github

Usage Example

M_001_InitialSchema.cs

[Migration(1)]
public class M_001_InitialSchema : Migration
{
	public override void Up()
	{
		Database.AddTable(
			"Users",
			new Column("Id", DbType.Guid, ColumnProperty.NotNull | ColumnProperty.PrimaryKey),
			new Column("CreationDate", DbType.DateTime, ColumnProperty.NotNull),
			new Column("ModificationDate", DbType.DateTime, ColumnProperty.NotNull),
			new Column("Name", DbType.String, 255),
			new Column("Password", DbType.String, 255),
			new Column("ExplicitRoles", DbType.String, int.MaxValue));
	}

	public override void Down()
	{
	}
}

Code to Apply Migration:

using (var p = ProviderFactory.Create(ProviderTypes.SQLite, connection, null))
{
	var migrator = new Migrator(p, typeof(M_001_InitialSchema).Assembly, false));

	if (migrator.LastAppliedMigrationVersion != null && migrator.LastAppliedMigrationVersion.Value > migrator.AssemblyLastMigrationVersion)
	{
		throw new Exception("Database has newer Migrations applied then the Software supports");
	}
	else
	{
		migrator.MigrateToLastVersion();
	}
}

What's different in the fork

In this fork the main changes are:

  • Now targets .Net Framework 4.0 instead of 2.0/3.5.
  • NetStandart 2.0 will be supported when released
  • Support for reserved words.
  • Support for guid types across all databases.
  • Utility classes for removing all tables etc. from a database (to support migration integration tests).
  • Warnings in Oracle when attempting to create column/table/key names that are over-length.
  • Removed reliance on deprecated SqlServer views such as Sysconstraints (to support Azure Sql Server deployment).
