laravel 输出最后执行sql 附:whereIn的使用方法

在sql语句执行前

DB::enableQueryLog();

sql sql sql sql sql

dd(DB::getQueryLog());

DB::enableQueryLog();    $data = UsersMenu::select('users_menu.*')      ->join('users as a','a.id','=','users_menu.user_id')      ->where('a.id', $user_id)->get();//    dd($data);//    DB::connection()->enableQueryLog();//    $data = DB::query('select * from users_menu,users where users.id = users_menu.user_id');    dd(DB::getQueryLog());

附：whereIn 后面跟的参数必须是数组

普通sql语句：SELECT users_menu . *

FROM users_menu
INNER JOIN users AS a ON a.id = users_menu.user_id
WHERE a.id

IN ( 1, 2 )

$data = UsersMenu::select('users_menu.*')  ->join('users as a','a.id','=','users_menu.user_id')  ->whereIn('a.id', $user_id);

此时的$user_id 是个数组才行
