我的表结构

My table structure

$employee_id = Tbl_payroll_leave_employeev2::select('payroll_employee_id')
   ->join('tbl_payroll_leave_schedulev2','tbl_payroll_leave_employee_v2.payroll_leave_employee_id','=','tbl_payroll_leave_schedulev2.payroll_leave_employee_id')
   ->where('payroll_leave_employee_id',$emp)
   ->get();

`推荐答案`

在这种情况下，必须定义字段<$表 tbl_payroll_leave_employee_v2 或表 tbl_payroll_leave_schedulev2

In where condition, you must define the field payroll_leave_employee_id of table tbl_payroll_leave_employee_v2 or table tbl_payroll_leave_schedulev2

$employee_id = Tbl_payroll_leave_employeev2::select('payroll_employee_id')
   ->join('tbl_payroll_leave_schedulev2','tbl_payroll_leave_employee_v2.payroll_leave_employee_id','=','tbl_payroll_leave_schedulev2.payroll_leave_employee_id')
   ->where('tbl_payroll_leave_schedulev2.payroll_leave_employee_id',$emp)
   ->get();
