## Installation

[Available in Hex](https://hex.pm/packages/sql_fmt), the package can be installed by adding `sql_fmt` to your list of
dependencies in `mix.exs`:

```elixir
def deps do
  [
    {:sql_fmt, "~> 0.1.0"}
  ]
end
```

Documentation can be found at [https://hexdocs.pm/sql_fmt](https://hexdocs.pm/sql_fmt).

## Example Output

After setting up SqlFmt in your application you can use the SqlFmt functions in order to format queries. Here are a
couple examples of queries with having parameters inline and with passing in the parameters separately:

```elixir
iex(1)> {:ok, formatted_sql} = SqlFmt.format_query("select * from businesses where id in ('c6f5c5f1-a1fc-4c9a-91f7-6aa40f1e233d', 'f339d4ce-96b6-4440-a541-28a0fb611139');")
{:ok, "SELECT\n  *\nFROM\n  businesses\nWHERE\n  id IN (\n    'c6f5c5f1-a1fc-4c9a-91f7-6aa40f1e233d',\n    'f339d4ce-96b6-4440-a541-28a0fb611139'\n  );"}

iex(2)> IO.puts(formatted_sql)
SELECT
  *
FROM
  businesses
WHERE
  id IN (
    'c6f5c5f1-a1fc-4c9a-91f7-6aa40f1e233d',
    'f339d4ce-96b6-4440-a541-28a0fb611139'
  );
:ok
```

```elixir
iex(1)> {:ok, formatted_sql} = SqlFmt.format_query_with_params("select * from help where help.\"col\" in $1;", ["'asdf'"])
{:ok, "SELECT\n  *\nFROM\n  help\nWHERE\n  help.\"col\" IN 'asdf';"}

iex(2)> IO.puts(formatted_sql)
SELECT
  *
FROM
  help
WHERE
  help."col" IN 'asdf';
:ok
```

Be sure to checkout the HexDocs as you can also provide formatting options to the functions to tailor the output to your
liking.

## Supporting SqlFmt

If you rely on this library help you debug your Ecto/SQL queries, it would much appreciated if you can give back
to the project in order to help ensure its continued development.

  statement formatting.
