【问题描述】：

我有一个带有时间戳字段的交易历史“TRANSACTION_HISTORY”表

TRANS_ID-----SIGNATURE_TIMESTAMP-------SIGNATURE_USR---INTERNAL_STATUS

2148091------22/07/2015 15:35:06 ---------- RS1------------00

2148091------22/07/2015 15:36:08----------  RS1------------01

2148091------22/07/2015 15:46:07----------  RS1------------B1

2139220------22/07/2015 15:36:07----------  RS1------------00

2148089------22/07/2015 15:31:42----------  GC1------------00

我正在尝试按用户状态在不同时间段按交易类型分组的每日交易计数。所有具有time stamp <= 9 A.M.then 9 A.M. 等的事务。

Status--------- 9:00 A.M.----------11:00 A.M.------3:00 P.M.---Grand Total

Pending (00) -----7-----------------9--------------21----------37

User1 ------------2-----------------3--------------13----------18

User2 ------------4-----------------2---------------6----------12

User3 ------------1-----------------4---------------2-----------7

Booked(01)  ------3-----------------4--------------12----------19

User1 ------------0-----------------1---------------7-----------8

User2 ------------2-----------------1---------------3-----------6

User3 ------------1-----------------2---------------2-----------5

Completed(B1)-----3-----------------4--------------12----------19

User1 ------------0-----------------1--------------7------------8

User2 ------------2-----------------1--------------3------------6

User3 ------------1-----------------2--------------2------------5

这是我目前写的代码：

选择 t.description，

   case
     when ts.id in ('B1', 'B2', 'B3') then
      'Completed'
     else
      ts.description
   end as status_Desc,
   hist.signature_timestamp,
   usr.login_name as user_name,
   case
     when hist.signature_timestamp <=
          to_date('22/07/2015 09:00:00', 'dd/mm/yyyy hh24:mi:ss') then
      '9 AM'
     when hist.signature_timestamp <=
          to_date('22/07/2015 11:00:00', 'dd/mm/yyyy hh24:mi:ss') then
      '11 AM'
     when hist.signature_timestamp <=
          to_date('22/07/2015 15:00:00', 'dd/mm/yyyy hh24:mi:ss') then
      '3 PM'
     when hist.signature_timestamp <=
          to_date('22/07/2015 18:30:00', 'dd/mm/yyyy hh24:mi:ss') then
      '6:30 PM'
   end as time_Slot from k$transaction_header  h,
   k$transtypes          t,
   k$transaction_history hist,
   k$usr                 usr,
   k$TRANSACTION_STATUS  ts where h.trtype = t.trtype and hist.trans_id = h.id  and usr.id = hist.signature_usr and ts.id = hist.internal_status   and H.ACCOUNT_DTE >= sysdate - 1

谢谢，

棘手但试试这个：

    with myCte
as
(
select Signature_Usr,
Case
 when CONVERT(Time,TimeofTransaction) < CONVERT(TIME,'1900-01-01 9:00:00.000') then Before9
 when CONVERT(Time,TimeofTransaction) < CONVERT(TIME,'1900-01-01 10:00:00.000') and 
  CONVERT(Time,TimeofTransaction) >= CONVERT(TIME,'1900-01-01 9:00:00.000') then After9Before10
 /* And So On */
 End as TimePeriord
 from myTable

)

select Signature_USR,COUNT(Signature_USR) as CountOfTrans,TimePeriod
 from myCte
 Group by Rollup(Signature_USR,TimePeriod)
