Ecto SQL

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 https://github.com/elixir-ecto/ecto_sql.git
$ cd ecto_sql
$ mix deps.get
$ mix test.all

Note that mix test.all runs the tests in test/ and the integration_tests 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' mcr.microsoft.com/mssql/server:2017-latest

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-20.3.8.26-alpine-3.11.6 --build-arg MYSQL=5.7 +integration-test-mysql
$ earthly -P -i --build-arg ELIXIR_BASE=1.8.2-erlang-20.3.8.26-alpine-3.11.6 --build-arg MSSQL=2019  +integration-test-mssql
$ earthly -P -i --build-arg ELIXIR_BASE=1.8.2-erlang-20.3.8.26-alpine-3.11.6 --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 127.0.0.1 -U postgres -d postgres ecto_test
MYSQL_PASSWORD=root mysql -h 127.0.0.1 -uroot -proot ecto_test
sqlcmd -U sa -P 'some!Password'
