在Laravel 5中编写自定义查询

Question

我想获取一些数据以及雇员的最后休假日期及其雇员姓名，因此我编写了此查询，该如何在laravel 5中执行此操作

SELECT employee.firstname,employee.lastname,employee.id,hr_leave.*,LAST(hr_leave.date) AS lastleaveday
FROM employee
INNER JOIN hr_leave
ON employee.id=hr_leave.hrid
WHERE hr_leave.oid=$id

employee
id  oid  firstname  lastname

id is primary key

hr_leave
id  oid  hrid  leave_from  leave_to  days  reason

id is primary key hrid is the foreign key

Answer 1

$empls= DB::table('employee')
            ->join('hr_leave', 'hr_leave.hrid', '=', 'employee.id')
            ->select('employee.*')
            ->where('hr_leave.oid', $id)
            ->get();

For Select --> DB::select('your query here.....');
For Insert --> DB::insert('your query here.....');
For Update --> DB::update('your query here.....');
