在oracle中缺少表达式

Question

我能知道为什么我会错过表达，这句话是否有任何错误。

    select *  
    from 
    (
       select student_id, attendance_day, attendance_id
       from attendance
    ) src
    pivot
    (
      sum(attendance_id)
      for attendance_day in ([to_date('23-Oct-2016', 'DD-Mon-YYYY')],                                         [to_date('24-Oct-2016', 'DD-Mon-YYYY')])
    ) piv;

Answer 1

更改此行

for attendance_day in ([to_date('23-Oct-2016', 'DD-Mon-YYYY')],                                         [to_date('24-Oct-2016', 'DD-Mon-YYYY')])

到

 for attendance_day in (to_date('23-Oct-2016', 'DD-Mon-YYYY'),to_date('24-Oct-2016', 'DD-Mon-YYYY'))
