Linked Server And Distributed Queries
Feb 6, 2002
Hi there,
I am trying to link one sql server to other sql server(version 7.0). I was able to link server1 to server2 by creating an odbc source and am able to see the tablenames when i click on the linked server tables.
My problem is..when i am trying to query on these tables its giving me error saying "OLE DB provider 'MSDASQL' does not contain table xxxxxx"
i am using select * from servername.tablename.dbo.tablename.
Any help on this will be appreciated.

We are migrating a database that makes use of distributed queries. In other words, it queries data from other databases on the same server, as well as from databases on linked servers.
The use of linked servers as well as linked databases (for lack of a better term) presents a challenge since we will need to register various new linked servers in the target environment. Ideally, we would like the database to be portable such that we will not have to worry about registering linked servers regardless of where it is hosted.
Is there a way to write distributed queries so that do not rely on linked servers/databases? For example:
SELECT * FROM [ServerName].[Database].[Owner].[TableName]
If there is such a method, it would make our database much more portable in terms of server migration.
TIA.

Hi,
There was a distributed trasaction set up and functioning fine, But gave the following error recently.
The operation could not be performed because the OLE DB provider 'SQLOLEDB' does not support distributed transactions
[OLE/DB provider returned message: Distributed transaction error]
Could anyone please help why is this error and how can be rectified.
Thanks in advance

Three weeks ago we began a project that involved importing data from an AIX DB2 6 environment via a linked server configuration. Following the data import a second query was executed against the db2 environment using data that resides in the new table within SQL 7 in the join statement (a very basic example is provided below) This was all accomplished in sequence via a package.
SELECT F_NAME, L_NAME, PASSWD
FROM SQL7.LOCALSRV.dbo.NEWUSERTBL as new, DB2.SYSIBM.MASTERTBL.OLDUESRTBL as old
WHERE new.USER_ID = old.USER_ID
Originally we had no problems and while the execute time was not exactly speedy it was tolerable as we would revisit optimization after we established if what we were trying to accomplish was feasible. At the outset the first data import to build the local table was immeadeate and then the distributed query to retirieve more info to build another local table against the DB2 server took aproxiamtly 1 minute per user row returned. Currently we are looking at still having an immeadeate data import (a matter of seconds to build the first table)but now we are looking at more than 1 hour returned for 1 correesponding row of data off of DB2. We are utilizing the the IBM DB2 ODBC DRIVER.
Any input or suggestions as to what could be causing this or perhaps a more efficeint way to code the statement would be much appreciated. Thanks in advance.

I am working on a linked server where a few of the queries use almost exclusively remote tables from 1 other server. I have read somewhere that there are options to specify where a query is performed but can't find it anywhere. Could someone tell me the command and how to use it or point me to something to read about it.
Thanks

I have a database containing my own tables and data and I wanted tobe able to query this against an accountancy program which has an ODBCdriver. This was never a problem with MS Access and Jet but I hit Jet'slimitations and have moved to SQL.Creating my own SQL database was no problem, but I was unsure of thebest way to be able to be able to have my SQL tables and my accountancysoftware tables appearing in the same Access front end.I created a linked server to the accountancy program. This wassuccessful in that I could see all the tables below the linked server inenterprise manager.My problem occurs when I try to bring the data from these tablesinto my SQL database.I create a new view in my database:-SELECT *FROM OPENQUERY(SAGE_SERVER, 'SELECT * FROM STOCK')(My linked server is called 'SAGE_SERVER' and I am trying to retrieveall columns from the STOCK table.)I then try to save this view and get the following errors.ODBC Error: [Microsoft][ODBC SQL Server Driver][SQL Server]The operationcould not be performed because the OLE DB provider 'MSDASQL' was unableto begin a distributed transaction.[Microsoft][ODBC SQL Server Driver][SQL Server]OLE DB Error Trace[OLE/DBProvider 'MSDASQL' ITransactionJoi JoinTransaction returned 0x8004d00a].Thanks in advance,Marcus Thornton.

Hi,
The distributed query seems to work on the management studio of the server where I have linked the other server to but not accross the network on other management studio with the same impersonated logins. The error I get is.

We get the below error while performing a distributed transaction on linked server. We have several linked servers configured in the source server and all of them succeed with the distributed transaction except on one.

We did all the basic troubleshooting and moreover the distributed transactions work fine if we use a remote server instead.
Error:

I receive the following error message when I run a distributed query against a loopback linked server in SQL Server 2005:
The Microsoft Distributed Transaction Coordinator (MS DTC) has cancelled the distributed transaction.
To resolve this problem, I was told that running a distributed query against a loopback linked server is not supported in SQL Server 2005. And I am suggested to use a remote server definition (sp_addserver) instead of a linked server definition to resolve this problem. (Although this is only a temporary resolution, which will deprecate in Katmai)
However, I run into another problem when I use the remote server definition. I receive the following error message:
Msg 18483, Level 14, State 1, Line 1

A recent SharePoint upgrade has rendered several views obsolete. I am redefining them so that our upper level executive reports show valid data.(yes, I know that doing anything to sharepoint could cause MS to deny support, having said that, this is something I've inherited and need to fix, pronto) The old view was created like so:
USE [AHMC]
GO
/****** Object: View [dbo].[vwSurgicalVolumes] Script Date: 09/04/2015 09:28:03 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE VIEW [dbo].[vwSurgicalVolumes] AS
SELECT
[code]....
As I said, this view is used in a report showing surgical minutes.SharePoint is now on a new server, which is linked differently (distributed?) I've used OPENQUERY to get my 'new' query to work;
SELECT *
FROM OPENQUERY ([PORTALWEBDB], 'SELECT
--AllLists
AL.tp_ID AS ALtpID
,AL.tp_WebID as altpwebid
,AL.tp_Title AS ALTitle
[code]....
My data (ie surgical minutes, etc) seems to be in the XML column, AUD.tp_ColumnSet . So I need to parse it out and convert it to INT to maintain consistency with the previous view. How do I do this within the context of the view definition?Here is a representation of the new and old view data copied to excel :
<datetime1>2014-08-14T04:00:00</datetime1><float1>2.000000000000000e+000</float1><float2>4.190000000000000e+002</float2><float3>1.600000000000000e+001</float3><float4>8.110000000000000e+002</float4><sql_variant1 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:sqltypes="http://schemas.microsoft.com/sqlserver/2004/sqltypes"
[Code] ....
can't format it to make it look decent. InHouseCases =2, InHouseMinutes=419, OutPatientCases =16, OutPatientMinutes=1230. This corresponds to the new data I can see in the XML column; 2.000000000000000e+000 is indeed 2 and 4.190000000000000e_002 is indeed 419.

Can someone please shed some light on what seems to me to be a common requirement.
If I create an alias or linked server to Server1 - say Alias1 - on Server1 and then use that name in a query on Server1, a remote/distributed query is always used (even though we are running on the local server and that overhead is completely unnecessary).
Is SQL Server really not capable of deciding that
select * from Alias1.db1.dbo.table1
and
select * from Server1.db1.dbo.table1
should be optimized and executed exactly the same when Alias1 is Server1, but that it is a distributed query ONLY when Alias1 is really referring to a remote server? I realize that the four part name is not necessary when I am referring to objects on the current server, but I am trying to write code that is server instance independent.
It just seems that if that is not possible, then the only way to create system independent stored procs that can run in dev, staging, and production environments and work with multiple databases on multiple servers is to create all sorts of scripts to regenerate all the procs whenever you move a database between servers?
If SQL Server is even close to the enterprise big iron server that MS now claims it is, it surely needs to support running in dev, staging, and production environments and work with multiple databases on multiple servers?!
I'm really looking for someone to tell me I'm missing something simple, and of course you can do this - but complex workarounds are invited too :-)
This is not something I am investigating as an academic exercise, I am already doing this, but I have to figure out how to do it better because with all these unnecessary distributed queries, performance is horrible.
Thanks

I am trying to write some admin only procedures which will collect information to one of my development server from other production and development servers.
I have created linked servers to access these other servers on the development server. This development server is SQL Server 2000 EE. Other servers which I want to access are 2000 and 2005 (vaious editions)
E.g I have another development server called PRODTEST which is SQL Server 2005 and on the development server I have created a linked server pointing to PRODTEST called TESTLINKSRV. I want to access new object catalog view (as I do not want to use sysobjects)
When I run the following query
SELECT * FROM [TESTLINKSRV].[DBNAME].[sys].[objects]
I get following error,
OLE DB error trace [Non-interface error: OLE DB provider does not contain the table: ProviderName=' TESTLINKSRV ', TableName='" DBNAME "."sys"."objects"'].
Msg 7314, Level 16, State 1, Line 1
OLE DB provider ' TESTLINKSRV ' does not contain table '"DBNAME"."sys"."objects"'. The table either does not exist or the current user does not have permissions on that table.
So I try this query
SELECT * FROM [TESTLINKSRV].[DBNAME].[sys.objects]
and I get following error
Msg 208, Level 16, State 1, Line 1
Invalid object name TESTLINKSRV.DBNAME.sys.objects'.
So bottom line is how do I access catalog views on a 2005 server from a 2000 server using linked server?
I hope someone understands what I am trying to achieve. Please let me know what is it that I am doing wrong.
Thank you

I have a ODBC data source setup for the AS400DB2 which is AS400JDE
The linked server has been created and all the tables are visible within enterprise manager.
If I had a table F0101, datasource = AS400JDE and linked server of AS400
How would I query it.
I gave tried AS400.AS400JDE.DBO.F0101, but i get the following error message.
OLE DB provider 'MSDASQL' does not contain table '"as400jde"."dbo"."f0101"'.

i added a linked sql 7 production server to my sql 7 development server so i could perform some data comparisons between the two
servers. after i linked in the server, i was able to see all the icons for the various tables in the production server. i went to query
analyzer and executed the following openquery:
select * from openquery(itdev_s08, 'select * from dbo.tablename')
it returned all the rows in the table. however, i want to comapre several different values so i needed a better way to query.
i then decided to try the distrbuted query below:
select * from linkedserver.dbname.dbo.tablename
however instead of a result set i got the error message below:
Server: Msg 7314, Level 16, State 1, Line 1
OLE DB provider 'SQLOLEDB' does not contain table '"dbname"."dbo"."tablename"'.
i went to BOL and it told me the only reason i would get this error is if the object did not exist or if i did not have permission
to use it. however, i know the object exists and i have the appropriate permission becuase i can obtain a result set from the
first query in the same query analyzer window. is my syntax incorrect? what am i doing wrong?
thanks!

I am getting the following error when with SQL Express.SQL Server blocked access to STATEMENT 'OpenRowset/OpenDatasource' of component 'Ad Hoc Distributed Queries' because this component is turned off as part of the security configuration for this server. A system administrator can enable the use of 'Ad Hoc Distributed Queries' by using sp_configure. For more information about enabling 'Ad Hoc Distributed Queries', see "Surface Area Configuration" in SQL Server Books Online. While I was very please to see such a verbose error and directions on where to find the answer I have yet to figure out how to turn this option on... I tried sp_configure 'Ad Hoc Distributed Queries', 1 but got the following error The configuration option 'Ad Hoc Distributed Queries' does not exist, or it may be an advanced option.If I execute only sp_configure it does not list Ad Hoc Distributied Queries as an option. I checked the sql Books Online and it tells me to use the Surface configuration tool which SQL Express does not seem to have.... Could someone help me out with this?Thanks - Mark

Hi,
I am trying to use linked servers (all SQLServer 6.5 and 7.0). When I issue a distributed query utilizing the four-part qualified table name for the distributed machine and using the LIKE operator, the execution plan shows that the remote query is returning ALL the rows from the remote distributed server, then performing the LIKE filter locally on my server! Needless to say, performance sux!
Any ideas what I may be doing wrong or what settings I am unaware of?
Example query:
select * from server.database.schema.table where column1 like 'A%'
Thanx in advance for any help.

Hi,
Is it possible to execute queries in parallel on multiple linked servers? I retrieve the checksum of a table on a linked servers like this:
SELECT * FROM OPENQUERY(Server1, 'SELECT CHECKSUM_AGG(BINARY_CHECKSUM(*) FROM Table1')
I need to do this on multiple linked servers at the same time - is this possible? I tried the following but my workstation executes the queries sequentially:
SELECT ("Query Server1"), ("Query Server2"), ("Query Server3"),..
Any suggestions??????

Hi,
I'm deploying an OLE DB provider to be used as linked server in on customer pc. The provider works ok on both machines I used to test it, one with Vista (64-bit), the other with XP (32-bit). Both machines have SQL server express 2005 SP2 (9.0.3042) installed.
Now, customer machine is again Vista (64-bit) with SQL server express 2005 SP2 (9.0.3054), and customer tested it on another Vista machine with SQL server express 2005 SP2 (9.0.3042). On both machines, following error occurs when SELECT statement is issued to the provider (though linked server creation runs smoothly):
Msg 7308, Level 16, State 1, Line 1
OLE DB provider 'XXX.XXXXX' cannot be used for distributed queries because the provider is configured to run in single-threaded apartment mode.
1) registry entry for ThreadingModel is Both
2) the provider works on my side
3) I can't seem to instantiate the provider on customer side even when I disallow provider to be inproc for SQL server, which would hint on some registration issue (maybe some leftovers on my local machines that are not present on customer side)
What is going on, again..?
Thanks for ideas..

Ok, this is a little convoluted so bear with me.
I have a SQL 2000 SP4 box on Windows 2000 Server with the Oracle 11g Client installed.
I've created a linked server to an Oracle database that lives offsite (sites connected with a fairly high speed VPN link).
There's a view on the Oracle database I'm trying to access through the linked server using the four-part naming convention*.
If I execute a fairly simple query against that view, the query runs until it eventually times out two hours later. And by simple, I mean something like this:
select * from CGN_LMS..CGNLMS.V_PRODUCTION_SUM where FISCAL_PERIOD = 200803
That happens if I use the OLE DB provider from Oracle or the one from MS.
Now, if I run the same type of query against that Oracle DB from Excel or Access (using the ODBC driver), the query will complete in seconds, returning about 800 rows of data.
For fun, I created a blank Access database with one linked table that points to that V_PRODUCTION_SUM view on the Oracle database, and one Query within that Access database that SELECTs * FROM the linked table WHERE FISCAL_PERIOD=200803.
I then created a linked server on my SQL 2000 server that points to the Access database. Now, if I hit that saved Access query through the SQL 2000 linked server, it also returns the results in about 9 seconds. If I query the linked table in the Access database and specify WHERE FISCAL_PERIOD = 200803, it completes in about 6-8 minutes.
So I guess my question is... WTF?
How is it that this:
SQL 2000 ->OLE DB provider-> Oracle
Times out after 2 hours, while this:
SQL 2000 -> Jet driver-> Access -> ODBC driver -> Oracle
returns all my results in seconds/minutes?
Couple other side notes...
A lot of the queries that I test with using this linked server work just fine. In fact, with this particular query, if I were to just pull SELECT TOP 800 * with no WHERE clause, the query would run rather quickly (like in 4 seconds).
Also, if I use OpenQuery instead of the 4-part linked server name, the queries return results as quickly as I'd hope. That might work as a last resort, but we have existing applications that use the 4-part names already and we'd rather not have to suss out and change all those if we don't have to.
Any help or insight would definitely be appreciated.

How would I specify this in a query as in the FROM part in a sql statement. I tried the obvious DVD_NASDOMINO.qlsdat.dbo.stmenqry and DVD_NAS.DOMINO.qlsdat.dbo.stmenqry.
Both returned errors in the query.

What can be the reason(s) why I can't get data from a linked server using an ODBC datasource that works fast & fine from MS Access?
I have an ODBC connection (System DSN) configured for an Informix ODBC driver.
The Test button (belonging to this driver-setup) reports a successfull connection test.
Getting data from this database by linking tables in MS Access works fast and easy.
But I have tried for many days now to setup a linked server from SQL Server (2005)
Creation goes fine, but as soon as I issue a query, (e.g. 'select * from infrem723...remotetable' or using 'openquery')
I get the following error:
---
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "MSDASQL" for linked server "infrem723" reported an error. The provider did not give any information about the error.
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "infrem723".
---
Why is Access able to read what "MSDASQL" cannot?
I am desperate - can anybody help?Thanks a lot!

idname, name, address, address2, awardedtoname, suppno
FROM contract INNER JOIN
house ON contract.idname = house.idname)
JOIN
(SELECT DISTINCT
tpd.PropertyNumber AS [Property No], tpd.Address1 + ' , ' + tpd.Address2 AS Estate, tpd.Address1 AS Address1,
[Code] ....
How I could combine the results?

I am using Linked Server in SQL Server 2008R2 connecting to a couple of Linked Servers.
I was able to connect Linked Servers, but I cannot point to a specific database in a Linked Server, also, I cannot rename Linked Server's name.
How to point the linked server to a specific database? How to rename the Linked Server?
The following is the code that I am using right now:
USE [master]
GO
EXEC master.dbo.sp_addlinkedserver
   @server = N'Machine123Instance456',
   @srvproduct=N'SQL Server' ;
GO
EXEC sp_addlinkedsrvlogin 'Machine123Instance456', 'false', NULL, 'username', 'password'Â Â

Is there a way to bypass the syntax checking when adding a stored procedure via a script?
I have a script that has a LINKed server reference (see below) .
INSERT
INTO ACTDMSLINKED.ACTDMS.DBO.COILS ..etc.
ACTDMSLINKED does not exist at the time I need to add the stored procedure that references it.
PLEASE to not tell me to add the LINK and then run the script. This is not an option in this scenerio.
Thanks,
Terry

We have a test db, a staging db and a live db. I have a stored procedure that runs fine on test and staging, but throws the following error on live.
The Microsoft Distributed Transaction Coordinator (MS DTC) has cancelled the distributed transaction.
The stored procedure uses linked servers and a transaction.
We're using the following transaction code in the stored procedure
BEGIN
BEGIN TRANSACTION
BEGIN TRY
---
procedure stuff here
---
COMMIT TRANSACTION
END TRY
BEGIN CATCH
DECLARE @ErrorSeverity INT, @ErrorNumber INT, @ErrorMessage NVARCHAR(4000), @ErrorState INT
SET @ErrorSeverity = ERROR_SEVERITY()
SET @ErrorNumber = ERROR_NUMBER()
SET @ErrorMessage = ERROR_MESSAGE()
SET @ErrorState = ERROR_STATE()
IF @ErrorState = 0
SET @ErrorState = 1
RAISERROR ('ERROR OCCURED:%d', @ErrorSeverity, @ErrorState, @ErrorNumber)
IF XACT_STATE() < 0
ROLLBACK TRANSACTION
END CATCH
END
I found the following link which seems to be the problem we're experiencinghttp://support.microsoft.com/kb/937517
The link includes a workaround which is the following:
"To prevent the SQLNCLI provider from sending an attention signal to the server, use the SQLNCLI provider to consume fully any rowsets that the OLE DB consumer creates. "
How do I use the SQLNCLI provider to fully consume any rowsets?
