Creating Migrations

A migration is just plain T-SQL saved in a .sql file. Individual commands are separated with the GO keyword for sql server, just like when using SSMS.

In the case of mysql and postgresql, the separator used is the semicolon (;) since GO is not supported on those databases

For example:

  Id int not null identity(1,1),
  Name nvarchar(50) not null,
  constraint PK_One primary key clustered (Id)

INSERT INTO One (Name) VALUES ('Person')

Migrations are executed as a transaction by default, which allows them to be rolled back if any command fails. You can disable this transaction for a specific migration by beginning the file with -- no transaction --.

We recommend prefixing migration file names with a zero-padded number so that the migrations are listed in chronological order. For example, a directory of migrations might look like:

0001 - Add Users table.sql
0002 - Add Posts.sql
0003 - Insert default users.sql
0004 - Add auth columns to Users.sql
0005 - Drop tables One To Three.sql

Running Migrations

Migrations run from the command line, in order to allow for automation to be used.

Command Line

To run migrations the typical usage is:

mig --folder="c:\path\to\migrations" --connection="Persist Security Info=False;Integrated Security=true;Initial Catalog=MyDatabase;server=localhost" --provider=sqlserver

By default the provider used is Sql Server

If you use integrated auth, you can use the --database and --server arguments instead of supplying a connection string (server defaults to "localhost").

mig --folder="c:\\path\\to\\migrations" --database=MyLocalDatabase --server=MyServer --provider=sqlserver

Use mig --help to show the complete set of options:

Usage: Minimig [OPTIONS]+
Runs all *.sql files in the directory --f=<folder> specified.
  The databse connection can be specified using the following combinations:
  -A connection string with the --connection along a --provider
      if no provider is specified, the program defaults to sqlserver.
  -Minimig can generate an integrated auth connection string using
      the --database and optional --server arguments, along a --provider.

  -h, --help                 Shows this help message.
  -c, --connection=VALUE     A connection string (can be PostgreSQL or 
                               SQLServer or MySQL). For integrated auth, you
                               can use --database and --server instead.
  -d, --database=VALUE       Generates an integrated auth connection string
                               for the specified database.
  -s, --server=VALUE         Generates an integrated auth connection string
                               with the specified server (default: localhost).
  -f, --folder=VALUE         The folder containing your .sql migration files
                               (defaults to current working directory).
      --timeout=VALUE        Command timeout duration in seconds (default:
      --preview              Run outstanding migrations, but roll them back.
  -p, --provider=VALUE       Use a specific database provider options:
                               sqlserver (default), postgresql, mysql.
      --global               Run all outstanding migrations in a single
                               transaction, if possible.
      --table=VALUE          Name of the table used to track migrations
                               (default: Migrations).
      --schema=VALUE         Name of the schema to be used to track
                               migrations (default: dbo for sqlserver, public
                               for postgresql, mysql for mysql).
      --force                Will rerun modified migrations.
      --version              Print version number.
      --count                Print the number of outstanding migrations.

Reverting Migrations

Minimig has no such concept. It is a forward-only tool. This is done to keep a minimalistic approach.

Running Migrations on CI

It is relatively trivial to configure a docker sql image and run minimig on a ci in order to test your sql migrations, a sample is included on the following repository


For uninstallation execute dotnet tool uninstall --global Minimig from terminal.


This library started as a fork from which is inactive
