SQL 2000行列式
Hi guys!
我有一个这样的表：
if exists (select 1
from sysobjects
where id = object_id( 'ProProcess ')
and type = 'U ')
drop table ProProcess
go


/*==============================================================*/
/* Table: ProProcess */
/*==============================================================*/
create table ProProcess (
PROP_ID bigint identity,
PROP_JOBNO varchar(10) not null,
PROP_PROCESS_NO varchar(30) not null,
PROP_CLASS_NO varchar(10) null,
PROP_MAC_NO varchar(30) null,
PROP_STARTDT datetime null,
PROP_FINISHDT datetime null,
PROP_CREATEDT datetime null,
PROP_UPDATEDT datetime null,
PROP_CREATER varchar(30) null,
constraint PK_PROPROCESS primary key (PROP_JOBNO, PROP_PROCESS_NO)
)
go

测试数据如下：
insert into ProProcess(PROP_JOBNO, PROP_PROCESS_NO, PROP_CLASS_NO, PROP_MAC_NO, PROP_STARTDT, PROP_FINISHDT)
select 'B0001 ', 'Get Order ', 'D ', NULL, '2007-05-02 12:00:00 ', '2007-05-02 12:01:00 ' union
select 'B0001 ', 'Make Film ', 'D ', NULL, '2007-05-02 12:05:00 ', '2007-05-02 12:11:00 ' union
select 'B0001 ', 'Open Paper ', 'D ', '01 ', '2007-05-02 12:12:00 ', '2007-05-02 12:15:00 ' union
select 'B0001 ', 'Printing ', 'D ', 'P02 ', '2007-05-02 12:17:00 ', '2007-05-02 12:37:00 ' union
select 'B0002 ', 'Get Order ', 'D ', NULL, '2007-05-02 12:00:00 ', '2007-05-02 12:01:00 ' union
select 'B0002 ', 'Make Film ', 'D ', NULL, '2007-05-02 12:05:00 ', '2007-05-02 12:11:00 ' union
select 'B0002 ', 'Open Paper ', 'D ', '02 ', '2007-05-02 12:12:00 ', '2007-05-02 12:15:00 ' union
select 'B0002 ', 'Printing ', 'D ', 'P01 ', '2007-05-02 12:17:00 ', '2007-05-02 12:37:00 '
GO

现在需要的结果为：
[PROP_JOBNO], [Get Order], [Get Order StartDT], [Get Order EndDT], [Make Film], [Make Film StartDT], [Make Film EndDT], [Open Paper], [Open Paper StartDT], [Open Paper EndDT], [Printing], [Printing StartDT], [Printing EndDT]
B0001, NULL, 2007-05-02 12:00:00,2007-05-02 12:01:00,NULL,2007-05-02 12:05:00,2007-05-02 12:11:00,01,2007-05-02 12:12:00,2007-05-02 12:15:00,P02,2007-05-02 12:17:00,2007-05-02 12:37:00
B0002, NULL, 2007-05-02 12:00:00,2007-05-02 12:01:00,NULL,2007-05-02 12:05:00,2007-05-02 12:11:00,02,2007-05-02 12:12:00,2007-05-02 12:15:00,P01,2007-05-02 12:17:00,2007-05-02 12:37:00

不知各位兄台有没有良方
