我正在尝试编写一个 SQL 查询来为看起来像的数据生成 orderid

 ID SYMBOL   Date          OrderID
 112    GR   24-Jan-13     0
 112    FIX  31-Aug-11     0
 112    FIX  29-Sep-11     0
 112    FIX  17-Nov-11     0
 112    MIN  19-Dec-08     0
 112    MIN  05-Feb-09     0
 445    GR   24-Jan-13     0
 445    GR   25-Jul-13     0
 445    FIX  31-Aug-11     0
 445    FIX  29-Sep-11     0
 445    FIX  17-Nov-11     0

需要输出为：

ID  SYMBOL  Date        OrderID
112 GR      24-Jan-13   1
112 GR      25-Jul-13   2
112 FIX     31-Aug-11   1
112 FIX     29-Sep-11   2
112 FIX     17-Nov-11   3
112 MIN     19-Dec-08   1
112 MIN     05-Feb-09   2
445 GR      24-Jan-13   1
445 GR      25-Jul-13   2
445 FIX     31-Aug-11   1
445 FIX     29-Sep-11   2
445 FIX     17-Nov-11   3

查询：我的尝试：

;with ctes  (ID, SYMBOL, date, orderid)as
 (
    select ID, SYMBOL, date , orderid from #temp

Union all

select  m.ID, m.SYMBOL, m.date, t.orderid + 1
from ctes t 
inner join #temp m on t.ID = m.id 
and t.symbol = m.symbol

  )select  * from ctes



create table #temp (id int, SYMBOL varchar(5), [Date] datetime, orderid int)
insert into #temp (id, symbol, [date], orderid)
values(112, 'GR',   '24-Jan-13',    0) 
insert into #temp (id, symbol, [date], orderid)
values(112,'GR', '25-Jul-13',   0)
insert into #temp (id, symbol, [date], orderid)
values(112, 'FIX',  '31-Aug-11' ,   0)
insert into #temp (id, symbol, [date], orderid)
values(112, 'FIX',  '29-Sep-11' ,   0)
insert into #temp (id, symbol, [date], orderid)
values(112, 'FIX',  '17-Nov-11' ,   0)

SQL Server 实际上有一个内置函数：ROW_NUMBER()

在你的情况下，你会像这样使用它：

SQL小提琴

MS SQL Server 2008 架构设置：

create table dbo.temp (id int, SYMBOL varchar(5), [Date] datetime, orderid int)
insert into dbo.temp (id, symbol, [date], orderid)
values(112, 'GR',   '24-Jan-13',    0) 
insert into dbo.temp (id, symbol, [date], orderid)
values(112,'GR', '25-Jul-13',   0)
insert into dbo.temp (id, symbol, [date], orderid)
values(112, 'FIX',  '31-Aug-11' ,   0)
insert into dbo.temp (id, symbol, [date], orderid)
values(112, 'FIX',  '29-Sep-11' ,   0)
insert into dbo.temp (id, symbol, [date], orderid)
values(112, 'FIX',  '17-Nov-11' ,   0)
insert into dbo.temp (id, symbol, [date], orderid)
values(112, 'FIX',  '14-Jan-13' ,   0)
insert into dbo.temp (id, symbol, [date], orderid)
values(112, 'MIN',  '19-Dec-08' ,   0)
insert into dbo.temp (id, symbol, [date], orderid)
values(112, 'MIN',  '05-Feb-09' ,   0)
insert into dbo.temp (id, symbol, [date], orderid)
values(112, 'MIN',  '19-Aug-09' ,   0)
insert into dbo.temp (id, symbol, [date], orderid)
values(112, 'MIN',  '19-Sep-13' ,   0)
insert into dbo.temp (id, symbol, [date], orderid)
values(445, 'GR',   '24-Jan-13' ,   0)
insert into dbo.temp (id, symbol, [date], orderid)
values(445, 'GR',   '25-Jul-13' ,   0)
insert into dbo.temp (id, symbol, [date], orderid)
values(445, 'FIX',  '31-Aug-11' ,   0)
insert into dbo.temp (id, symbol, [date], orderid)
values(445, 'FIX',  '29-Sep-11' ,   0)
insert into dbo.temp (id, symbol, [date], orderid)
values(445, 'FIX',  '17-Nov-11',    0)

查询 1：

SELECT id,SYMBOL,[Date],
       ROW_NUMBER()OVER(PARTITION BY id,SYMBOL ORDER BY [Date]) AS OrderId
  FROM dbo.Temp
 ORDER BY id,SYMBOL,[Date]

结果：

|  ID | SYMBOL |                             DATE | ORDERID |
