我無法按以下方式進行Oracle SQL分組

Question

我收到的錯誤是缺少表達

下面是我的SQL語句

select 
ecell_name, 
ecell_relation,
pmm_datetime,

pmHoExeOutAttLteInterFQci1 As_Exec_Attempt_Out
--pmHoExeOutSuccLteInterFQci1 As_Exec_Succes_Out, 
--(pmHoTooEarlyHoQci1) As Early_HO, (pmHoTooLateHoQci1)  As Late_HO, 
--(pmHoWrongCellReestQci1) As WrongCellReest_HO, 
--(pmHoWrongCellQci1) As WrongCell_HO, (pmHoOscQci1) As Osc_HO

from PMMCOUNTER_DB.LC_N_EUTRANCELLREL_D

where substr (ECELL_NAME,1,4) in 'BKPA' and pmm_datetime BETWEEN TO_DATE('14/06/2019','DD/MM/YYYY') AND TO_DATE('15/06/2019','DD/MM/YYYY') and direction='Outgoing' 
and GROUP BY ecell_relation

Answer 1

首先，您需要刪除and orepator您的前group by 。 其次，您需要使用group by所有選定的字段。 這應該工作：

 select ecell_name,
       ecell_relation,
       pmm_datetime,

       pmHoExeOutAttLteInterFQci1 As_Exec_Attempt_Out
--pmHoExeOutSuccLteInterFQci1 As_Exec_Succes_Out, 
--(pmHoTooEarlyHoQci1) As Early_HO, (pmHoTooLateHoQci1)  As Late_HO, 
--(pmHoWrongCellReestQci1) As WrongCellReest_HO, 
--(pmHoWrongCellQci1) As WrongCell_HO, (pmHoOscQci1) As Osc_HO

  from PMMCOUNTER_DB.LC_N_EUTRANCELLREL_D

 where substr(ECELL_NAME, 1, 4) in 'BKPA'
   and pmm_datetime BETWEEN TO_DATE('14/06/2019', 'DD/MM/YYYY') AND
       TO_DATE('15/06/2019', 'DD/MM/YYYY')
   and direction = 'Outgoing' 
 GROUP BY ecell_relation, ecell_name, pmm_datetime, pmHoExeOutAttLteInterFQci1

Answer 2

在GROUP BY之前刪除運算符“和”
