Hi,

I don't know if I missed anything. I have 2 member tables and one
partition view in SQL 2000 defined as following

CREATE VIEW Server1.dbo.UTable
AS
SELECT *
FROM Server1..pTable1
UNION ALL
SELECT *
FROM Server2..pTable2

CREATE TABLE pTable1 (
[ID1] [int] IDENTITY (1000, 2) NOT NULL ,
[ID2] [int] NOT NULL ,

...<other columns>.........

CONSTRAINT [PK_tblLot] PRIMARY KEY CLUSTERED
(
[ID1],
[ID2]
) ON [PRIMARY] ,
CHECK ([ID2] = 1015)
) ON [PRIMARY]


CREATE TABLE [pTable2] (
[ID1] [int] IDENTITY (1001, 2) NOT NULL ,
[ID2] [int] NOT NULL ,

...<other columns>.........

CONSTRAINT [PK_tblLot] PRIMARY KEY NONCLUSTERED
(
[ID1],
[ID2]
) WITH FILLFACTOR = 90 ON [PRIMARY] ,
CHECK ([ID2] <> 1015)
) ON [PRIMARY]


SELECT is working fine. However, I got error message if I issue an
update command such as

UPDATE UTable
SET somecol = someval
Where somecol2 = somecond

Server: Msg 4436, Level 16, State 12, Line 1
UNION ALL view 'UTable' is not updatable because a partitioning column
was not found.

Anyone have any idea? ID2 is my partition column, why the SQL 2K
doesn't see it. It is a part of primary key, having checking
constrain, and no other constrain on it. Am I missing something?

Thanks a lot.

You cannot have identity columns in an updatable partitioned view.

In that case, how should I deal with the ID1? I need that column to
be an identity column. Thanks.

Consider putting an INSTEAD OF trigger on the partitioned view.

Yes, <> is not a permitted operator. You need to rewrite

CHECK ([ID2] <> 1015)

to

CHECK ([ID2] < 1015 OR [ID2] > 1015)

Another story is whether this view will be very efficient. You should
probably add an index on ID2, or put it first in the primary key.

Oh, I should have added the the IDENTITY appears to work fine, as soon
as I had changed the CHECK constraint.

Thanks for all your help. I changed CHECK constraint, and now it is
not complaining about missing partition column anymore, however, when
do the Update or Insert it gives out Server: Msg 4450, Level 16, State
1, Line 1
Cannot update partitioned view 'UTable' because the definition of the
view column 'ID1' in table '[pTable1]' has a IDENTITY constraint. So
I think IDENTITY is the another issue. As Tom mentioned in his post,
using INSTEAD OF trigger, would anyone please give me an example,
never used before.

Again, thank you very much for your help.
