Hi there,
I'm trying to run the following script on a linked server:
SET XACT_ABORT on
INSERT INTO report_server_a.master.dbo.tblSpaceChecks(Drive, DriveSpace)
EXEC report_server_a.master.dbo.xp_fixeddrives
UPDATE report_server_a.master.dbo.tblSpaceChecks
SET Srvname = @@Servername
The INSERT part goes well, unless I leave the XACT_ABORT OFF; the update part generates:
Could not open table '"master"."dbo"."tblSpaceChecks"' from OLE DB provider 'SQLOLEDB'. The provider could not support a row lookup position. The provider indicates that conflicts occurred with other properties or requirements.
There is more, but not important.
If I run the script on the 'master' server there is no problem. I am not sure what is happening here. If I execute a qualified DELETE operation on the linkedserver, it goes well. I have tried adding a Identity keyfield to the table, but nodice.
I found a similar question via GOOGLE, the answer there was that the targettable should be qualified as SERVER.DB.OWNER.TABLE. Since I am already doing this it is no help to me.
Any hints? Am I missing something here?
BTW, the table I use is:
CREATE TABLE [dbo].[tblSpaceChecks] (
[Drive] [varchar] (5) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[DriveSpace] [varchar] (10) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[Srvname] [varchar] (20) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[Checkdate] [datetime] NULL
) ON [PRIMARY]
GO

Well, I found out WHAT caused the problem and how to work around it. The systemvariable @@SERVERNAME is not accepted as input for the update. I now declare a VARCHAR variable, set it to @@SERVERNAME, and now the update is accepted. Same for the GETDATE() function, had to select this function into my own varaible, and then the update is accepted.

I am still wondering why this is. If anyone can answer this, please let me know. I really hate not understanding..

I would guess that it is due to @@servername probably being declared as sysname (I think that relates to nvarchar(128)) behind the scenes and your field is declared as a varchar(20). I'll have to try something like this when I get some free time to see what it really does.
