Demo after the previous post, showing just executing SQL
Interactive Elixir (1.8.1) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)> alias Ora.Repo
Ora.Repo
iex(2)> result = Ecto.Adapters.SQL.query!(Repo, "select * from scott.emp where empno = :1 ", [7369])
13:34:54.892 [debug] QUERY OK db=16.0ms
select * from scott.emp where empno = :1 [7369]
%{
columns: ["EMPNO", "ENAME", "JOB", "MGR", "HIREDATE", "SAL", "COMM", "DEPTNO"],
num_rows: 1,
rows: [
[7369, "SMITH", "CLERK", 7902, ~N[1980-12-17 00:00:00], 800.0, nil, 20]
]
}

Note. Can also use Ecto.Adapters.SQL.query which will then return the usual tuple
iex(3)> result = Ecto.Adapters.SQL.query(Repo, "select * from scott.emp where empno = :1 ", [7369])
13:38:05.739 [debug] QUERY OK db=16.0ms
select * from scott.emp where empno = :1 [7369]
{:ok,
%{
columns: ["EMPNO", "ENAME", "JOB", "MGR", "HIREDATE", "SAL", "COMM", "DEPTNO"],

}}

Need to set MIX_ENV to dev/test/prod to switch between environments.
