我正在尝试构建一个使用 skip() 和 take() 函数的查询，由于某种原因它一直offset 0在末尾添加而不是它应该是LIMIT 0,0

代码：

    $dbSearch = new SchoolInfo;
    $dbSearch = $dbSearch->where(function($query) use($search) {

        $query->where('school_name', 'LIKE', '%'.$search.'%')
            ->orWhere('address_1', 'LIKE', '%'.$search.'%')
            ->orWhere('address_2', 'LIKE', '%'.$search.'%')
            ->orWhere('address_3', 'LIKE', '%'.$search.'%')
            ->orWhere('address_4', 'LIKE', '%'.$search.'%')
            ->orWhere('county', 'LIKE', '%'.$search.'%')
            ->orWhere('postcode', 'LIKE', '%'.$search.'%')
            ->orWhere('head_teacher_email', 'LIKE', '%'.$search.'%')
            ->orWhere('head_teacher_first', 'LIKE', '%'.$search.'%')
            ->orWhere('head_teacher_last', 'LIKE', '%'.$search.'%');
    });
    $results = $dbSearch
        ->skip($startat)
        ->take($startat)
        ->orderBy('school_name', 'ASC')
        ->get();

这是我得到的错误

当您这样做时skip(n)，它会offset n向查询中添加一个，正如您所注意到的。当你这样做时take(n)，它会为查询添加一个 n 的限制。然后，在构造实际查询时，限制会覆盖偏移量。

但是take(0)，你是说你想要零结果。Eloquent 认为您不想应用限制，因此不会。相反，只剩下偏移量，它本身并不构成有效的查询。

确保该take()值大于零，你应该没问题。:)

（注意：这对于联合查询并不完全正确，但这完全是另一回事。）
