Ecto SQL

[![Build Status](](

Ecto SQL ([documentation]( provides building blocks for writing SQL adapters for Ecto. It features:

  * The Ecto.Adapters.SQL module as an entry point for all SQL-based adapters
  * Default implementations for Postgres (Ecto.Adapters.Postgres), MySQL (Ecto.Adapters.MyXQL), and MSSQL (Ecto.Adapters.Tds)
  * A test sandbox (Ecto.Adapters.SQL.Sandbox) that concurrently runs database tests inside transactions
  * Support for database migrations via Mix tasks

To learn more about getting started, [see the Ecto repository](

## Running tests

Clone the repo and fetch its dependencies:

    $ git clone
    $ cd ecto_sql
    $ mix deps.get
    $ mix test.all

Note that `mix test.all` runs the tests in `test/` and the `integration_test`s for each adapter: `pg`, `myxql` and `tds`.

You can also use a local Ecto checkout if desired:

    $ ECTO_PATH=../ecto mix test.all

You can run tests against a specific Ecto adapter by using the `ECTO_ADAPTER` environment variable:

    $ ECTO_ADAPTER=pg mix test

MySQL and PostgreSQL can be installed directly on most systems. For MSSQL, you may need to run it as a Docker image:

    docker run -d -p 1433:1433 --name mssql -e 'ACCEPT_EULA=Y' -e 'MSSQL_SA_PASSWORD=some!Password'

### Running containerized tests

It is also possible to run the integration tests under a containerized environment using [earthly](

    $ earthly -P +all

You can also use this to interactively debug any failing integration tests using the corresponding commands:

    $ earthly -P -i --build-arg ELIXIR_BASE=1.8.2-erlang- --build-arg MYSQL=5.7 +integration-test-mysql
    $ earthly -P -i --build-arg ELIXIR_BASE=1.8.2-erlang- --build-arg MSSQL=2019  +integration-test-mssql
    $ earthly -P -i --build-arg ELIXIR_BASE=1.8.2-erlang- --build-arg POSTGRES=11.11 +integration-test-postgres

Then once you enter the containerized shell, you can inspect the underlying databases with the respective commands:

    PGPASSWORD=postgres psql -h -U postgres -d postgres ecto_test
    MYSQL_PASSWORD=root mysql -h -uroot -proot ecto_test
    sqlcmd -U sa -P 'some!Password'
