Ecdo [![Build Status](]( [![Coverage Status](](

Like an [ecto](, but dynamic. EcDo.
Ecto is a domain specific language for writing queries and interacting with databases in Elixir.
Ecdo is a dynamic interface for ecto.

Ecdo was build for accessing it from erlang(elixir need to be in path)
or simplify building dynamic interface, for example API.

Example of using from erlang:

'Elixir.Ecdo':query({<<"weather">>, 'Elixir.Weather'}, #{<<"where">> => [{'==', <<"">>, 1}]})
'Elixir.Ecdo':query({<<"weather">>, 'Elixir.Weather'}, #{<<"where">> => <<" == 1">>})

Example of use from elixir:

Ecdo.query {"weather", Weather}, %{"where" => " == 1"}

Simple example of building API:

defmodule Weather.Api do
  def json(json) do
    map = Poison.decode! json
    # may be restrict something
    Ecdo.query({"weather", Weather}, map) |> Repo.all

# Example of use:

Weather.Api.json ~S({"where": "weather.temp_lo > 25", "limit": 10})

Due to some direct manipulations with ecto intern AST, ecdo aims to have always close to 100% of test cover.

## Usage

You need to add both Ecdo and the database adapter as a dependency to your `mix.exs` file. The supported databases and their adapters are:

Database                | Ecto Adapter           | Dependency
:---------------------- | :--------------------- | :-------------------
PostgreSQL              | Ecto.Adapters.Postgres | [postgrex][postgrex]
MySQL                   | Ecto.Adapters.MySQL    | [mariaex][mariaex]
MSSQL                   | Tds.Ecto               | [tds_ecto][tds_ecto]
SQLite3                 | Sqlite.Ecto            | [sqlite_ecto][sqlite_ecto]


For example, if you want to use MySQL, add to your `mix.exs` file:

defp deps do
  [{:mariaex, ">= 0.0.0"},
   {:ecdo, "~> 0.1.0"}]

and update your applications list to include both projects:

def application do
  [applications: [:mariaex, :ecdo]]
