Server Aliases/linked Servers Cause Remote Queries
Apr 4, 2008Can 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.
Run Remote Proc Without Using Linked Servers
Aug 1, 2002Hi
Is there a way (workaround) of running a remote stored
procedure as pass through query and without having to use
linked servers. Something similar OPENROWSET when
selecting form a remote object?
Many thanks

Linked Server Time Difference
May 31, 2006I am using SQL 2000 and/or SQL 2005 to link to an Oracle Db usingOPENQUERY.The SQL 2000 box is SP4 on Win2000.I can run a query thru Q.A. for SQL 2000 or I can run an Oracle querythru SQL-Plus to see the data. But, if I run a date-query using thelinked server then SQL Server returns a TIME that is off by 4 hours.SQL Query:SELECT * FROM OPENQUERY( ORASERVER, 'SELECT MYDATE FROM MYTABLE')Oracle Query:'SELECT MYDATE FROM MYTABLE'Oracle results:04/16/2006 01:07:00SQL 2000 result:04/16/2006 05:07:00Has anyone seen this before? Is there a fix?I have searched the newsgroups and MS Kb but can not find an answer.Thanks,Marty

Sql Server 2000 - Linked Servers
Jan 23, 2001I'm working with SQL Server 2000 installed in Windows 2000. When i tried to add the 'servername' as a linked server , i got the following message:
" Error: 15038. The Server 'servername' already exists."
When i execute "sp_linkedservers" , i could see the name "servername" in the list. But before doing this i had Restored the "MSDB" database on this server. Should i use "sp_droplinkedservers" and add them again.
Any comments are most welcome.
Thanks, Santha.
Server 2003 - Linked Servers
May 7, 2008I've set up a Linked server connection to a Windows 2003 server running MySql using SSL.
I can run SQL and T-SQL from the query window using the Server management studio on the
server, and everything is good.
As soon as I apply a trigger to a table on our local server running the same
script, I get a "linked server unable to begin a distributed transaction"
error.
I've google'ed my brains out on this error and tried both Mysql ODBC drivers
3.51 and 5.1 and keep getting the same error.
Any suggestions? Thanks, Tony T
Setting Up Linked Servers With SQL Server And Oracle

Linked Remote Server
Feb 11, 2005I need to be able to query remote server tables and join them to local tables. Thought that linked server would be best so that I can use local stored procs for parameters if needed. I have no administrative control over remote server. I have been given select permissions only to one db on remote server. Both servers are sql2000, local machine has spk3.
I have established the remote server in network client utility. I can register the remote server in EM, look at tables. I can run select statements against the remote server in QA when I log in and specify that server. I can reference an odbc data connection with web pages and display rowsets.
Next, I created a linked server under security, using sql (since it's an sql 2000 db) with the same name used above in the client utility and the em. I created a local login with the same name and password as the login used successfully above (Paragraph 2). On the security tab, I've used sa as the local login and entered the remote user and password, using the default 'be made without using a security context'. When I try to view the tables (which I can do through registered) or run this through QA:
SELECT * FROM OPENQUERY(CASCE, 'SELECT person_pk, lastname FROM dbName.dbo.tblName (NOLOCK)'),
I get: sql error 17: sql server does not exist or access denied
If I edit security, wipe out the top settings and specify the security context below using the login information, same thing. Tried messing around with different security contexts, no help or ole db error.
Any help? In addition, any tutorials out there a little more user friendly than the bol? I think I want to use the linked server option and stored procs.

Linked Server: Works Local, But Not Remote
Nov 14, 2007I have created a linked server (to an AS/400) via MSDASQL. It works fine when I execute queries locally (i.e. from Management Studio running on the SQL 2005 server).
However, when I execute a query from a remote machine I get an error (see below for the exact message).
I know the ODBC connection is between the SQL server and the AS/400, and that the remote client does not have connectivity to the AS/400. But shouldn't the SQL server be able to pass the query through to the linked server even if the query is initiated from a remote machine?
Does anyone have any suggestions on how I can resolve this problem so that queries against the linked server can be executed from remote machines?
Errors:
OLE DB provider "MSDASQL" for linked server "MERCURY" returned message "[Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed".
OLE DB provider "MSDASQL" for linked server "MERCURY" returned message "[IBM][iSeries Access ODBC Driver]Key value in connection string too long.".

Copying a backup file is not an option either, and Mailing it on media make it a significant delay.

Remote Update Having A Linked Server Takes Forever To Execute
Oct 17, 2006UPDATE CD SET col1=SR.col1,col2=SR.col2,col3=SR.col3,col4=SR.col4,col5=SR.col5,col6=SR.col6,col7=SR.col7,
col8=SR.col8,col9=SR.col9,col10=SR.col10
FROM LNKSQL1.db1.DBO.Table1 CD
join Table2 USRI on USRI.col00 = CD.col00
join table3 SR on USRI.col00 = SR.col00
Here, I'm trying to tun this from an instance and do a remote update. col00 is a primary key and there is a clustered index that exists on this column. When I run this query, it does a 'select * from tabl1' on the remote server and that table has about 60 million rows. I don't understand why it would do a select *... Also, we migrated to SQL 2005 a week or so back but before that everything was running smooth. I dont have the execution plan from before but this statement was fast. Right now, I can't run this statement at all. It takes about 37 secs to do one update. But if I did the update on a local server doing remote joins here, it would work fine. When I tried to show the execution plan, it took about 10 mins to show up an estimated plan and 99% of the time was spent on Remote scan. Please let me know what I can do to improve my situation. Thank you
Remote Scan On Linked Server - Fast SELECT/Slow UPDATE
Aug 14, 2001In an ASP, I have a dynamically created SQL statement that amounts to "SELECT * FROM Server1.myDB.dbo.myTable WHERE Col1 = 1" (Col1 is the table's primary key). It returns the data immediately when executed.
However, when the same record is updated with "UPDATE Server1.myDB.dbo.myTable SET Comments = 'blah blah blah' WHERE Col1 = 1", the page times out before the query can complete.
I watched the program in Profiler, and I saw on the update that sp_cursorfetch was being executed as an RPC once per each row in the table. In a table of 78000 records, the timeout occurs well before the last record is fetched, and the update bombs.
I can run the same statements in Query Analyzer from a linked server and have the same results. The execution plan shows that a Remote Query is occurring on the select that returns 1 row, and a Remote Scan is taking place on the update scanning 78000 rows (I guess this is where all the sp_cursorfetch calls are happening...?).
How can I prevent the Remote Scan? How can I prevent the execution of the RPC sp_cursorfetch for each row in the remote table?
Thank you!

Remote Servers ?
Jan 8, 2001Hi Everybody,
Can anybody help me on Remote Servers. I want to create a remote server
from 6.5 to 7.0. Is it possible to create a remote server from 6.5 to 7.0?.
From the Books online I saw remote server related commands. Like Linked servers in 7.0, tables of 7.0 can be extracted like "select * from <Remote_server>.<Database>.<Owner>.<Table_name>", in 6.5 Remote servers?. How do we execute a stored procedure of 7.0 Database from 6.5 server in remote server?.
Can anybody guide me on the above topics.
Tks in advance,

sp_addlinkedserver @server = '233.56.152.112',
@srvproduct = N'SQL Server'
This caused the server to show up in the linked servers under Security folder in the Enterprise Manager GUI.
BUT WHEN RUNNING THE FOLLOWING QUERY:
(Select * from 233.56.152.112].remoteDATABASE.dbo.remoteTABLE)
I GET THE FOLLOWING ERROR:

Linked Server And Remote Server Help
Jan 14, 2004I'm documenting various server configurations such as linked and remote servers. Rather then clicking on each linked and remote server to view their properties I am trying to query sysservers. According to BOL, the column isremote is 1 if server is a remote server, else 0 if server is a linked server. When I query sysservers I see just the opposite. Is BOL wrong or am I missing something? Through Enterprise Manager I see 3 remote servers and 13 linked servers. syssservers shows 3 servers with isremote = 0 and 13 servers with isremote = 1.
Also, I understand remote servers are provided for backward compatibility. If that is the case, why is the default instance listed under remote server and not linked server. Also, why does replication list repl_distribution under remote server and in some cases the subscriber server is also listed under remote servers.
Thanks, Dave
