我正在尝试编写一个SQL查询来生成看起来像
的数据的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

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)

SQL Server实际上有一个buildin函数：ROW_NUMBER()
在你的情况下，你会像这样使用它：
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]
