我一直在尝试将这个mysql查询转换为laravel查询，但我无法解决。
SELECT max(a.date) as max FROM table1 a, table2 b where
a.publishing_time<='2015-02-27 12:30:00' and a.Status='1' and
a.id=b.table1_id
表1字段为：-
sl | date | publishing_time | status
表2字段为
sl | table1_id | additional_fields
我被卡住了，请帮我
尝试此Laravel查询
DB::table('table1 as a')
->select(DB::raw('max(a.date) as max_date'))
->join('table 2 as b', 'a.id', '=', 'b.table1_id')
->where('a.publishing_time'<='2015-02-27 12:30:00')
->where(Status='1')
->get();
试试这个。。
这是laravel联接查询
$resource = DB::table('table1')->join('table2', 'table1.id', '=', 'table2.table1_id')->where('table1.publishing_time','<=','2015-02-27 12:30:00')->where('table1.Status','1');
尝试以下操作：
DB::table('table a as a')->join('table b as b', 'a.id', '=', 'b.table1_id')->max('a.data as max')->where('a.publishing_time', '<=', '2015-02-27 12:30:00')->where('a.status', 1)->get();
