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%')))")

我遵循这个帖子（Eloquent WHERE LIKE clause with multiple columns）并且它工作正常，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，那么结果变量总是为空，无论变量$ q中的内容是否与一列或多列相匹配：

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

我很确定我错过了什么，但我找不到它是什么。提前谢谢。

您可以这样做：

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

上述Eloquent将输出类似于

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%')"

Eloquent WHERE LIKE子句，包含两列以上
