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 not in query
DB::table(..)->select(..)->whereNotIn('book_price', [100,200])->get();
Example 3: laravel orWhere
$camps = $field->camps()->where('status', 0)->where(function ($q) {
$q->where('sex', Auth::user()->sex)->orWhere('sex', 0);
})->get();
Example 4: laravel where multiple conditions
$query->where([
['column_1', '=', 'value_1'],
['column_2', '<>', 'value_2'],
[COLUMN, OPERATOR, VALUE],
...
])
Example 5: laravel wher in
$users = DB::table('users')
->whereIn('id', [1, 2, 3])
->get();
Example 6: laravel db::query update
DB::table('user')->where('email', $userEmail)->update(array('member_type' => $plan));
