Example Usage

Look at the following examples. They are way cooler with the Laravel Query Enrich. Aren't they? :)

Categorize books into different price categories (using case when)

With Laravel Query Enrich

$books = Book::select(
    'id',
    'name',
    QE::case()
        ->when(c('price'), '>', 100)->then('expensive')
        ->when(QE::condition(50, '<', c('price')), QE::condition(c('price'), '<=', 100))->then('moderate')
        ->else('affordable')
        ->as('price_category')
)->get();

Without Laravel Query Enrich

$books = Book::select(
    'id',
    'name',
    DB::raw('
        CASE
            WHEN price > 100 THEN "expensive"
            WHEN price BETWEEN 50 AND 100 THEN "moderate"
            ELSE "affordable"
        END AS price_category
    ')
)->get();

Raw SQL

select case
           when `price` > 100 then 'expensive'
           when (50 < `price` and `price` <= 100) then 'moderate'
           else 'affordable' end as `price_category`
from `books`

Fetch orders placed in the last 7 days

With Laravel Query Enrich

$recentOrders = DB::table('orders')
    ->where(c('created_at'), '>=', QE::subDate(QE::now(), 7, Unit::DAY))
    ->get();

Without Laravel Query Enrich

$recentOrders = DB::table('orders')
    ->whereRaw('created_at >= NOW() - INTERVAL ? DAY', 7)
    ->get();

Raw Query

SELECT *
FROM `orders`
WHERE `created_at` >= NOW() - INTERVAL 7 DAY;

Get average monthly price for oil and gas (using avg function)

With Laravel Query Enrich

$monthlyPrices = DB::table('prices')
    ->select(
        QE::avg(c('oil'))->as('oil'),
        QE::avg(c('gas'))->as('gas'),
        'month'
    )
    ->groupBy('month')
    ->get();

Without Laravel Query Enrich

$monthlyPrices = DB::table('prices')
    ->select(DB::raw('avg(`oil`) as `oil`, avg(`gas`) as `gas`, `month`'))
    ->groupBy('month')
    ->get();

Raw Query

select avg(`oil`) as `oil`, avg(`gas`) as `gas`, `month`
from `prices`
group by `month`

Fetch authors and check if they have any books (using exists query)

With Laravel Query Enrich

$authors = DB::table('authors')->select(
    'id',
    'first_name',
    'last_name',
    QE::exists(
        Db::table('books')->where('books.author_id', c('authors.id'))
    )->as('has_book')
)->orderBy(
    'authors.id'
)->get();

Without Laravel Query Enrich

$authors = DB::table('authors')
->select(
    'id',
    'first_name',
    'last_name',
    DB::raw('exists(select * from `books` where `books`.`author_id` = `authors`.`id`) as `has_book`'))
->orderBy(
    'authors.id',
)
->get();

Raw Query

select `id`,
       `first_name`,
       `last_name`,
       exists(select * from `books` where `books`.`author_id` = `authors`.`id`) as `result`
from `authors`
order by `authors`.`id` asc

Getting full name on database level (using concatws)

With Laravel Query Enrich

$authors = Author::select(
    'first_name',
    'last_name',
    QE::concatWS(' ', c('first_name'), c('last_name'))->as('result')
)->get();

Without Laravel Query Enrich

$author = Author::select(
    'first_name',
    'last_name',
    DB::raw("concat_ws(' ', `first_name`, `last_name`) as `result`")
)->first();

Raw Query

select `first_name`, `last_name`, concat_ws(' ', `first_name`, `last_name`) as `result`
from `authors`
