Laravel Query Enrich is designed to easily create complex database queries in Laravel without having to write complicated SQL code. Here are some examples taken from the readme:
Example of fetching 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;

Using the avg function for grabbing the average monthly price for oil and gas
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`

Using an 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 a full name 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`
