Introduction

blade-sql provides the generation and execution of SQL using Blade, Laravel's template engine

When you want to write a complex SQL with more than 100 rows, isn't it hard to write it in the query builder?
Sometimes you want to write raw SQL for tuning purposes
In such cases, blade-sql is useful!

Requirements

• PHP(^7.3|^8.0)
• PDO
• Laravel:(^6.0|^7.0|^8.0)

Installation

composer require schrosis/blade-sql

Laravel uses Package Auto-Discovery, so doesn't require you to manually add the ServiceProvider

If you don't use auto-discovery, add the BladeSQLServiceProvider to the providers array in config/app.php
And if you use facade aliases, add BladeSQL to the aliases array

Schrosis\BladeSQL\Providers\BladeSQLServiceProvider::class,

'BladeSQL' => Schrosis\BladeSQL\Facades\BladeSQL::class,

Copy the package config to your local config with the publish command

php artisan vendor:publish --provider="Schrosis\BladeSQL\Providers\BladeSQLServiceProvider"

Usage

Create .blade.php file for blade-sql in resources/sql/ dir

{{-- For example, resources/sql/users/select.blade.php --}}
SELECT id, name FROM users WHERE id = :id

Execute SELECT Query

Execute a query using the BladeSQL facade

use Schrosis\BladeSQL\Facades\BladeSQL;

$user = BladeSQL::select('users.select', ['id' => 1])->first();
// (object)[
//     'id' => '1',
//     'name' => 'examplename'
// ]

The result of a select query is a Collection object of stdClass

You can also turn it into a Collection object of Models or your Entity

use Schrosis\BladeSQL\Facades\BladeSQL;
use App\Moldes\Todo;
use App\Entities\YourTodoEntity;

$stdClassCollection = BladeSQL::select('todos.select');

// to model collection
$modelCollection = $stdClassCollection
    ->model(Todo::class); // or model(new Todo())

// to entity collection
$entityCollection = $stdClassCollection
    ->entity(YourTodoEntity::class);

The entity method argument expects a class with a method named fromArray
Otherwise, you can use the Collection::map()

class YourTodoEntity
{
    private $id;
    private $contents;
    private $finished_at;
    private $created_at;

    public static fromArray(array $data)
    {
        // some code
    }
}

Execute INSERT UPDATE DELETE Query

You can also use the BladeSQL facade to perform an insert update delete query

The way to call these methods is the same as the select
The difference is that these methods return the number of rows that have been updated

$insertedRowNum = BladeSQL::insert('todos.new', [
    'contents' => 'Implement that function',
]);

$updatedRowNum = BladeSQL::update('todos.done', [
    'id' => 1,
    'finished_at' => \Carbon\Carbon::now(),
]);

$deletedRowNum = BladeSQL::delete('todos.delete', [
    'id' => 1,
]);

Run on a specific connection

If you want to use a connection other than the default one, call the setConnection method

// Same string value as the argument of DB::connection()
BladeSQL::setConnection('mysql::write')->update('users.change-password', $queryParams);
// or
// Accept ConnectionInterface
$connection = DB::connection('mysql::write');
BladeSQL::setConnection($connection)->update('users.change-password', $queryParams);

Also use it when doing a transaction

Blade Directives and Components

In addition to the basic features of blade, provides directives and components similar to Java's mybatis

@where

Erase the leading AND or OR and prefix it with WHERE

@where component is useful when using @if to create WHERE clauses

@where
AND col_1 = 'value'
AND col_2 = 'value'
@endwhere

It will compile like this

WHERE col_1 = 'value'
AND col_2 = 'value'

If the $slot of @where is empty, the first WHERE is not attached

@set

Works just like @where
Remove the , at the end and prefix it with SET

@set component is useful when using @if to create a SET clause for an update query.

@set
col_1 = 'value',
col_2 = 'value',
@endset

It will compile like this

SET col_1 = 'value',
col_2 = 'value'

@IN

@IN directive Create an IN clause from an array

@IN(id_list)

If $id_list is [1, 2, 3], it will be compiled like this

IN(?, ?, ?)

@LIKE

@LIKE directive escapes values that are bound to the LIKE clause

@LIKE(name)

If $name is 'strawberry 100%', then it will compile like this

LIKE ? ESCAPE '\'

And 'strawberry 100%' will be escaped to 'strawberry 100\%'

You can also easily add _ and %

{{-- if $name is 'strawberry 100%' --}}
@LIKE({name}%) {{-- 'strawberry 100\%%' --}}
@LIKE(_{name}) {{-- '_strawberry 100\%' --}}
@LIKE(%{name}%) {{-- '%strawberry 100\%%' --}}
