Eloquent WHERE LIKE子句,包含两列以上

Question

我一直在尝试在Laravel中进行查询,在原始SQL中将是这样的

"SELECT * FROM students WHERE (((students.user_id)=$id) AND (((students.name) Like '%$q%') OR ((students.last_name) Like '%$q%') OR ((students.email) Like '%$q%')))")

我遵循这个线程(Eloquent WHERE LIKE子句有多个列),它工作正常,但只有两列Ej:

$students = student::where(user_id, Auth::id())
         ->whereRaw('concat(name," ",last_name) like ?', "%{$q}%")
         ->paginate(9);

但是,如果我添加两列以上,那么无论变量$ q中的内容是否与一列或多列匹配,结果变量始终为空:

$students = student::where(user_id, Auth::id())
         ->whereRaw('concat(name," ",last_name," ",email) like ?', "%{$q}%")
         ->paginate(9)

我很确定我错过了什么,但我找不到它是什么.提前致谢.

你可以这样做:

$students = student::where('user_id', Auth::id())->where(function($query) use ($q) {
    $query->where('name', 'LIKE', '%'.$q.'%')
        ->orWhere('last_name', 'LIKE', '%'.$q.'%')
        ->orWhere('email', 'LIKE', '%'.$q.'%');
})->paginate(9);

上面的Eloquent会输出类似的SQL

"SELECT * FROM students WHERE students.user_id = $id AND (students.name like '%$q%' OR students.last_name Like '%$q%' OR students.email Like '%$q%')"
