Linked Servers And Distributed Quries
Dec 6, 1999
I have Two Access Databases connected as Linked servers through ODBC driver.
I want to run a Distributed Query .
The SQL is as follows:
SELECT Alias1.FiledNames,Alias2.FiledNames from
FROM LinkedServer1.DatabaseName1.dbo.Tablename1 AS Alias1,
LinkedServer2.DatabaseName2.dbo.Tablename2 AS Alias2
It gives me this error message.
ODBC: Msg 0, Level 19, State 1
SqlDumpExceptionHandler: Process 12 generated fatal exception c0000005 EXCEPTION_ACCESS_VIOLATION. SQL Server is terminating this process.
Connection Broken
Am i missing something?
Thanks in Adavance

Can anyone know the difference between using distributed queries for transfering data and replication.
Which is more reliable and which is the better way?
If the volume of database over 2,000,000 with nearly 100 columns,which is the better method?

Is it possible to query linked servers without the Distributed Transaction Coordinator service enabled or allowing network access?
Is that ONLY for transactions? What if I just wanted to read the data and nothing else?

Hi there,
I have two SQL servers, SERVERA and SERVERB. They are on two different VLAN's within our corporate network. They are physically only about 5 feet apart. SERVERA is SQL2005 while SERVERB is SQL2000. I am running a distruted transaction as a result of an insert on SERVERA which then causes a Stored procedure stored on SERVERA to insert a record on a table on SERVERB. I know my syntax is correct, 'cause I can get the Process to work between two servers (one SQL2000 and the other SQL2005) on the same VLAN. But when I run it in the problem environment, I get the following error message:
SQL Execution Error
Executed SQL Statement: INSERT INTO Tablea(recordid, recordtext) values(3, 'Testagain')
Error source: .Net SQLClient Data Provider
Error Message: The operation could not be performed because OLE DB provider "SQLNCL1" for linked server "SERVERB" was unable to being a distributed transaction.
I have checked to make sure that MSDTC is running and it is on both servers.
Any help would be greatly appreciated. Thanks! - Eric-

I have an existing table that I want to partition across multiple servers. I am having a hard time finding an article that explains how to do it.
I am in the process of designing applying a scale out architecture to our database...but have hit this brick wall.
Any help would be great.
Thanks!

I have 4 servers, 2 each for application (Dev & Prod)
DEV 1 & DEV 2 are standalone servers
Prod 1 & Prod 2 are Windows Clustered Servers.
From one application to other we do Distributed transactions. Dev 1 - Dev 2 or Dev 2 - Dev 1 can start DTC and working fine,but issue comes when Prod 1 - Prod 2 or Prod 2 - Prod 1. I get error message OLE DB provider "SQLNCLI" for linked server "xyz" returned message "No transaction is active.".
Msg 7391, Level 16, State 2, Line 3
The operation could not be performed because OLE DB provider "SQLNCLI" for linked server "xyz" was unable to begin a distributed transaction.
I have tested Dev 1 - Prod 1, Dev 1 - Prod 2, Dev 2 - Prod 1, Dev 2 - Prod 2 everything is working fine only Production servers are causing issue.
I enabled all settings needed for DTC on Cluster MSDTC service but no luck.

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

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.

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.
OLE DB provider "SQLNCLI" for linked server "usbo-sql01" returned message "Communication link failure".
Msg 10054, Level 16, State 1, Line 0
TCP Provider: An existing connection was forcibly closed by the remote host.

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:
OLE DB provider "SQLNCLI10" for linked server "SERVERNAME.REDMOND.CORP.MICROSOFT.COM" returned message "No transaction is active.".
Msg 7391, Level 16, State 2, Line 3
The operation could not be performed because OLE DB provider "SQLNCLI10" for linked server "SERVERNAME.REDMOND.CORP.MICROSOFT.COM" was unable to begin a distributed transaction.
Test code:
begin distributed transaction
select top 10 * from [SERVERNAME.REDMOND.CORP.MICROSOFT.COM].master.sys.objects
ROLLBACK

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

Hi All,
I have successfully linked a server and had SQL queries running

(Server: Msg 7353, Level 16, State 1, Line 1)
I've dropped the link and recreated it but I still get the same error
message. Can anyone help???

Hi,
I'm using SQL Server 7.0 SP1.
I have a DTS package that requires me to link 2 servers
and query both in order to get my set of records that I
want to Transform. My query runs fine in QA. I copy and
paste it into the SQL Query window of the transformation.
I click Preview and all that happens is a quick flicker of
the DTS window. When I go to Transformations, there are
no source columns.
Here is a copy of my code that I'm trying to use:
-------------------------------------------------------
declare@start_dteas datetime,
@end_dteas datetime
SELECT@start_dte = date_data_range_start_dte,
@END_DTE = date_data_range_END_dte
FROMSIDDEV.SID_DEVELOPMENT.DBO.T901_RUN
WHERERUN_ID = (selectmax(run_id)
from
SIDDEV.SID_DEVELOPMENT.DBO.t901_run
whererun_type_cd = 'M')
SELECTRUN_ID
INTO#RUNS
FROMCRMDEV02.MDCORE.DBO.T901_RUN
WHEREDATE_DATA_RANGE_START_DTE >= @START_DTE
ANDDATE_DATA_RANGE_END_DTE <= @END_DTE
SELECTT70.*
FROM
CRMDEV02.MDCORE.DBO.T70_MD_UNIVERSE_RELATIONSHIP_M A
NGT AS T70 JOIN #RUNS
ONT70.RUN_ID = #RUNS.RUN_ID
DROP TABLE #RUNS
------------------------------------------------------
Is there an issue with Linked Servers and DTS?
Any help would be greatly appreciated.
Thanks in advance,
Darrin

When I create linked server using integrated security and <they will be impersonated> option I get this:
Server: Msg 18456, Level 14, State 1, Line 1 Login failed for user ''
MS Technet says that SQL Server 7 doesn't allow double hops and to use mappings to standard security login to work around. @#%%~~@@#@#&^%@#
Impersonating to version 6.5 works fine.
Is there any way to link servers using ONLY integrated security?
Any help would be much appreciated.

Hi.
I'm working with SQL Server 7.0 and I've been reading about the linked server option. My question is, if it's possible to link a server with a SQLBase database 7.01.
I have download some drivers to my computer, the odbc driver for sqlbase and the sqlbase ole db driver as well, but when I try to add a new linked server in the enterprise, in the provider name option I can not see any provider name addressing to Centura or Sql base driver.
Has anybody an idea how to make this connection then? or the right way for doing it??
Thanks for any help can be offered.
Regards, Elvia.

I have two 7.0 servers and I want to run a distributed query.
I did sp_addlinkedserver to link server B to server A
and I did sp_addlinkedsrvlogin for a specific login.
After adding login when I try to access a table on server B it
says login failed
All the logins are NT authenticated (in both the servers, So
both servers have same logins.)
but it is not working.

Hi all
I try to configure Linked Servers from the query analyze , and have some troubles.
My steps are :
1. from the enterprise mennenger , add 2 new servers : srv1 , srv2 (both SQL7)
2. from the query analyzer of srv1.master: "sp_addlinkedserver 'srv2'"
3. from the query analyzer of srv1.master:
"sp_addlinkedsrvlogin 'srv2',false,null,'sa','myPass'"
4. select * from srv2.pubs.srv2Table
5. I get the next error :"error 6 : Specified SQL srever not found."
