Mariaex 
Usage
Add Mariaex as a dependency in your mix.exs file.
def deps do
[{:mariaex, "~> 0.8.2"} ]
endAfter you are done, run mix deps.get in your shell to fetch and compile Mariaex. Start an interactive Elixir shell with iex -S mix.
iex(1)> {:ok, p} = Mariaex.start_link(username: "ecto", database: "ecto_test")
{:ok, #PID<0.108.0>}
iex(2)> Mariaex.query(p, "CREATE TABLE test1 (id serial, title text)")
{:ok, %Mariaex.Result{columns: [], command: :create, num_rows: 0, rows: []}}
iex(3)> Mariaex.query(p, "INSERT INTO test1 VALUES(1, 'test')")
{:ok, %Mariaex.Result{columns: [], command: :insert, num_rows: 1, rows: []}}
iex(4)> Mariaex.query(p, "INSERT INTO test1 VALUES(2, 'test2')")
{:ok, %Mariaex.Result{columns: [], command: :insert, num_rows: 1, rows: []}}
iex(5)> Mariaex.query(p, "SELECT id, title FROM test1")
{:ok,
%Mariaex.Result{columns: ["id", "title"], command: :select, num_rows: 2,
rows: [[1, "test"], [2, "test2"]}}
Configuration
Important configuration, which depends on used charset for support unicode chars, see :binary_as
in Mariaex.start_link/1
JSON library
As default, Poison is used for JSON library in mariaex to support JSON column.
If you want to use another library, please set config.exs like below.
config :mariaex, json_library: SomeLibrary=======
