Example 1: laravel join
Inner Join : ->join('contacts', 'users.id', '=', 'contacts.user_id')
Left Join : ->leftJoin('posts', 'users.id', '=', 'posts.user_id')
Right Join : ->rightJoin('posts', 'users.id', '=', 'posts.user_id')
Cross Join : ->crossJoin('colors')
Advance Queries :
-----------------
->join('contacts', function ($join) {
$join->on('users.id', '=', 'contacts.user_id')
->where('contacts.user_id', '>', 5);
})
Example 2: laravel update from query
$affected = DB::table('users')
->where('id', 1)
->update(['votes' => 1]);
Example 3: laravel not in query
DB::table(..)->select(..)->whereNotIn('book_price', [100,200])->get();
Example 4: laravel orWhere
$camps = $field->camps()->where('status', 0)->where(function ($q) {
$q->where('sex', Auth::user()->sex)->orWhere('sex', 0);
})->get();
Example 5: wherein laravel
DB::table('user')->whereIn('id', [100,200])->get();
Example 6: laravel where has
use Illuminate\Database\Eloquent\Builder;
$posts = App\Post::whereHas('comments', function (Builder $query) {
$query->where('content', 'like', 'foo%');
})->get();
$posts = App\Post::whereHas('comments', function (Builder $query) {
$query->where('content', 'like', 'foo%');
}, '>=', 10)->get();
