我尝试构建一个使用skip()和take()函数的查询,由于某种原因,它一直在最后添加offset 0
,而不应该是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

答案 0 :(得分:2)
当您执行skip(n)
时,它会向您的查询添加offset n
,正如您所注意到的那样。当您执行take(n)
时,它会为查询添加n的限制。然后,在构造实际查询时,该限制将覆盖偏移量。
但是take(0)
,你说你想要零结果。 Eloquent认为你不想申请限制,所以不这样做。相反,只剩下偏移量,并且本身不构成有效查询。
确保take()
值大于零,你应该没问题。 :)
(注意:对于工会化查询,这不完全正确,但这完全不同。)
