OPENQUERY Vs EXECUTE On A Linked Server -- What Is Better?
May 22, 2007
Can anyone tell me, if, generally, the performance or the cost of executing a pass-through command on a linked server in SQL Server 2005 would be better using OPENQUERY or the new option with EXECUTE -- whether the two servers are on the same box or not? I haven't been able to find a comparison between the two.
Have there been any tests of the difference?
What effect on performance is there with 'rpc out' set with sp_serveroption so EXECUTE can be used?
To be more specific I have a development box with SQL Server 2005 and Oracle 9.2.
The new option with EXECUTE would be something like the example in MSDN (Example J.) at:
http://msdn2.microsoft.com/en-us/library/ms188332.aspx
EXEC ( 'SELECT * FROM scott.emp') AT ORACLE;

I need to run a report using a linked server on SQL 2005. The report was running really slow so I tried doing an OPENQUERY which makes it a lot faster. However, I need to pass some parameters and not sure how to do it using OPENQUERY. Here is the query:
SELECT RTRIM(client.ClientID) AS ClientID, client.name2 AS Client_Name, Project.Project, Project.StatutoryDueDate AS DueDate, Project.Extension1, Project.Extension2, Project.StartDate AS AsofDate, Project.PromiseDate AS CommitmentDate, Project.ReceivedDate AS InfoIn, Task.TaskID, Task.Empid, Task.ActualStartDate, Task.ActualFinishDate, Client.Partner,
STAFF.PersonalTitle AS PIC,
Client.Manager,
MGR.PersonalTitle AS TIC,
Client.Accountant,
ACCT.PersonalTitle AS AIC,
CASE WHEN Task.TaskID = 'PREP' THEN EMP.personaltitle END AS Prep_BY,
CASE WHEN Task.TaskID = 'REV' THEN EMP.personaltitle END AS Rev_By,
CASE WHEN Task.TaskID = 'PREP' THEN Task.ActualStartDate END AS Prep_Date,
CASE WHEN Task.TaskID = 'REV' THEN Task.ActualStartDate END AS Rev_Date,
CASE WHEN Task.TaskID = 'MAIL' THEN Task.ActualFinishDate END AS Mailed_Date,
CASE WHEN Task.TaskID = 'TESNT' THEN Task.ActualFinishDate END AS TE_OUT,
CASE WHEN Task.TaskID = 'TERCD' THEN Task.ActualFinishDate END AS TE_IN
FROM PROJECT, PROJCUS, TASK LEFT OUTER JOIN STAFF EMP ON TASK.EMPID = EMP.EMPID, CLIENT LEFT OUTER JOIN STAFF ON CLIENT.Partner = STAFF.EmpID LEFT OUTER JOIN STAFF MGR ON CLIENT.Manager = MGR.EmpID LEFT OUTER JOIN STAFF ACCT ON CLIENT.Accountant = ACCT.EMPID
WHERE CLIENT.ClientID = PROJECT.ClientID AND CLIENT.Engagement = PROJECT.Engagement AND PROJECT.Project = PROJCUS.Project AND
PROJECT.Engagement = PROJCUS.Engagement AND PROJECT.ClientID = PROJCUS.ClientID AND CLIENT.ClientID = TASK.ClientID AND CLIENT.Engagement = TASK.Engagement AND PROJECT.Project = TASK.Project AND CLIENT.DroppedDate IS NULL AND ((PROJCUS.[~Custom35])='BT') AND (CLIENT.OfficeID in (@OfficeID)) AND (PROJECT.Project in (@Project))

Hi,
I run openquery() from a client application(sql 2005) to query SSAS data(sql 2005) through a linked server(sql 2005), but I get the following error:
OLE DB provider "MSOLAP" for linked server "LINKEDMINING" returned message "An error was encountered in the transport layer.".
OLE DB provider "MSOLAP" for linked server "LINKEDMINING" returned message "The peer prematurely closed the connection.".
Msg 7303, Level 16, State 1, Procedure gettpdt, Line 3
Cannot initialize the data source object of OLE DB provider "MSOLAP" for linked server "LINKEDMINING".
And, I am sure that I have made the MSOLAP provider Allow inprocess.
What can i do for this. Please advise.

The following used to work before we had to chang the Linked Server Name (Out of my control)
select * from
openquery(LServ1,'SET FMTONLY OFF; exec [LServ1].database1.dbo.proc1 @issue_id=1,@extract_type=1')
Now the Linked Server Name changed from LServ1 ==> LServ1.DOMAINMSSQLSERVER,1200
(1200-Port #)
Now when i change the Linked Server Name, It gives me an error @ openquery.
I tried the following and so far no luck
select * from
openquery(LServ1.DOMAINMSSQLSERVER,1200,'SET FMTONLY OFF; exec [LServ1].database1.dbo.proc1 @issue_id=1,@extract_type=1')
and
select * from
openquery([LServ1.DOMAINMSSQLSERVER,1200],'SET FMTONLY OFF; exec [LServ1].database1.dbo.proc1 @issue_id=1,@extract_type=1')
Basically how do i specify the NEW Linked Server Name(as a paramter for "openquery"?)
Thanks!

Can someone please tell me what oracle software needs to be installed on a sql server machine that will link to an Oracle database on an NT4 machine.
Also can you also confirm if you have successfully executed an oracle stored procedure from sql server using the open query function. If yes, How? because I have read about people having prolems executing stored procedures with arguments using the OPENQUERY Function.
Thanks

I have a simple SQL statement that runs in a web-based admin system as follows:
INSERT INTO someTable SELECT * FROM OPENQUERY (someLinkedServer, 'SELECT someTable.* FROM someTable WHERE ID = 57')
This works fine on my development system, but on the production system I get the following error:
[Microsoft][ODBC SQL Server Driver][SQL Server]OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "someDB" returned message "Unspecified error".
The linked server definitely exists on the production machine; and the following stored procedure has been run:
exec sp_addlinkedsrvlogin 'someLinkedServer', false, 'machinenameIUSR_macninename', 'Admin', NULLto allow the internet anonymous user account to log into the linked server.
Also:
-- the internet anonymous user has full control permissions over the Access database file
-- the internet anonymous user has full control permissions the administrator/local settings/temp directory (after I read somewhere that this could cause problems; though no such permission is needed to make it work on my development machine.)
As far as I can tell, the production machine (2003 Server) is configured the same way in all relevant respects as the development machine (2000 Server) where everything works.
With such a vague error message, I have no idea where to start, and would appreciate any advice.

I thought this may be very helpful for those of you using SQL7 linked server to Oracle 7.3.4 Database. After much research and no answers when opening a case with Microsoft I finally figured out how to delete using Openquery. There are a few missing pieces of information that would of been a great help in BOL. The first is, the Microsoft OLE DB for Oracle is not the correct choice for the data provier as one might think. The correct choice is the Oracle Provider for OLE DB. The next important thing is that the Oracle table you are querying MUST have a unique index on at least one column not necessarily the column in your WHERE clause. Thirdly, you get much better performance and use of indexes if you put the WHERE clause inside the OPENQUERY statement. Here is the syntax that I found to work in my application:
DECLARE @ins_id varchar(7)
DECLARE @sqlstring nvarchar(2000)
Select @ins_id = '123456'
Select @ins_id = convert(int, @ins_id)
select @ins_id
select @sqlstring = 'DELETE FROM OPENQUERY(LinkedServerName,"SELECT * FROM OracleTableName WHERE I_ID = '
+ '' + @ins_id + '' + '")'
select @sqlstring
EXEC sp_executesql @sqlstring
*Note...I had an additional data conversion from varchar to integer in my statement.
I hope this information helps any others who are having trouble performing this type of task.

Hello.
Suddenly OPENQUERY had started to raise an exception 'Msg 7355, Level 16, State 1, Line 1
The OLE DB provider "SQLNCLI" for linked server "sql2000" supplied inconsistent metadata for a column. The name was changed at execution time.'
The OPENQUERY stament looks like:
Code Block
SELECT * FROM OPENQUERY(sql2000, 'execute dbo.sc_List @AmountId = 24, @WorkMode=1, @SortMode=0')
I don't know what has been changed - seems that everyting is OK.
The problem is that sql2000 is MS SQL 2000 server and this statment is executed on the MS SQL 2005 server.
dbo.sc_List is a procedure that selects data and I need insert that data to the temporary table on the sql2005 server to make some calculations.
I've used OPENQUERY to prevent DTC coordinator from starting distributed transaction.
Whole statement originally looks like
Code Block
INSERT INTO #Templates SELECT * FROM OPENQUERY(sql2000, 'execute dbo.sc_List @AmountId = 24, @WorkMode=1, @SortMode=0')
where #Template is temporary table with columns that exactly match with stored procedure output.
Help me please - what is wrong with sql servers? I know that this query has been working fine for a months and now - such strange errors. I should say also that strored procedure returns always the same columns when called - there is one large select inside it.
Thank you.

I'm posting this because I found this solution after much digging.
The goal here is to incorporate a variable parameter within a OPENQUERY and, ultimately build a dynamic Where clause for use within a OPENQUERY linked server routine. I'm posting because I spent a lot of time trying to get this to work and also, have seen other posts here that hinted it wasn't doable.
First of all - there a good quick article that gets close for FoxPro and possibly works as is for ACCESS:
http://support.microsoft.com/default.aspx?scid=kb;en-us;314520
Here's code for a solution:
DECLARE @OPENQUERY nvarchar(4000),
@TSQL nvarchar(4000),
@FAMILY CHAR(10)
SET @FAMILY='Touring'
SET @OPENQUERY = 'SELECT * FROM OPENQUERY(VFP,'''
SET @TSQL = 'select cov,family,model from vinmast where family='+'['+@FAMILY+']'')'
EXEC (@OPENQUERY+@TSQL)
All shown are single quotes.
In Visual Foxpro, ' ' or " " or [ ] can be used a delimeters
In addition, if wanting to build a dynamic where clause, you could do something like:
SET @TSQL = 'select cov,family,model from vinmast '
IF <some condition met to include FAMILY filter>
Begin
SET @TSQL=@TSQL+'where family=['+@DUTFAMILY+']'''
SET @TSQL=@TSQL+ ')'
End
-----------------
Here's the entire Stored Procedure:
CREATE PROCEDURE dbo.ewo_sp_DUTLookup
(
@DUTPROJECT char(25)=NULL,--Project
@DUTFAMILY char(10)=NULL,--Family
@DUTMODEL char(20)=NULL,--Model
@DUTYEAR char(4)=NULL,--Model Year
@DUTBEGIN char(25)=NULL,--Beginning of COV/DUT number
@DEBUG int=0
)
AS
DECLARE @OPENQUERY varchar(4000),
@TSQL varchar(4000),
@TWHERE varchar(4000),
@intErrorCode int
select @intErrorCode = @@ERROR,
@TSQL='',
@TWHERE=''
IF @intErrorCode=0
Begin
SET @OPENQUERY = 'SELECT * FROM OPENQUERY(VFP,'''
SET @TSQL = ' select dut_pk,cov,family,model,project,modelyr from vinmast '
End
set @intErrorCode = @@ERROR
IF @intErrorCode = 0 and
@DUTFAMILY is not NULL or
@DUTMODEL is not NULL or
@DUTPROJECT is not NULL or
@DUTYEAR is not NULL or
@DUTBEGIN is not NULL
set @TWHERE=' where '
-- Check for Family criteria
If @intErrorCode = 0 and @DUTFAMILY is not NULL and Len(@TWHERE)>0
SET @TWHERE=@TWHERE+' family=['+@DUTFAMILY+'] AND '
set @intErrorCode = @@ERROR

IF @intErrorCode=0 AND substring(@TWHERE,Len(@TWHERE)-3,4)=' AND '
Begin
set @TWHERE=Substring(@TWHERE,1,Len(@TWHERE)-3)
select @intErrorCode=@@ERROR
End
SET @TWHERE=@TWHERE+''')'
IF @debug<>0 and @intErrorCode=0
Begin
print @intErrorCode
print @OPENQUERY
print @TSQL

Hi All -
My Set up:
Server A - Oracle 10g Database
Server B - SQL2005
Client PC - Sql Express
Server A holds all data. I am using a linked server to connect server A and B. I use a set of stored procedures containing the openquery() syntax to get data from Server A to Server B. These stored procedures run every 20 minutes. I then create a publisher on Server B. I subscribe from the client PC to publisher to get data down from Server B to client(Download only subscription).
When I fire up the stored procedures and attempt to replicate, everything works fine. It appears after about 4-5 hours of the stored procedures running replication begins to hang more and and more until eventually it hangs for about 10 minutes and I recieve the following error:
Command attempted:
{call sp_MSreleasemakegenerationapplock}
Error messages:
The merge process was unable to create a new generation at the 'Publisher'. Troubleshoot by restarting the synchronization with verbose history logging and specify an output file to which to write. (Source: MSSQL_REPL, Error number: MSSQL_REPL-2147200994)
I'm not sure if there is an error with openquery() locking? There is some locking activity going on with the TempDB and and Server B database. I've also come across some threads talking about the agent profiles. I'm very new to replication and very confused by all of the options in the agent profiles. Any help would be greatly appreciated!

Hello,
pls. let me know where I could post if this is the wrong place.
I have a Firebird 1.5 application. I created a linked server from my SQL
Server 2000 to the firebird database. In SQL Server Query Analyzer I get errors from various ODBC drivers with "normal" queryies like
SELECT LVNR FROM LINKEDSRV...LVVERW
Pls. note, this all works perfectly in MS Access databases with ODBC-Links to Firebird!
From a programmer of a commercial ODBC driver I heard that this problem may be caused internally by SQL Server, there may be no solution possible in the ODBC driver. One workaround would be to use the OPENQUERY-Syntax like
SELECT * FROM OPENQUERY(LINKEDSRV, 'select LVNR from LVVERW ')
Are there any other solutions? Are there any known issues with firebird odbc-drivers and sql server? Are
there any known good drivers for the use with sql-server? What is the purpose of OPENQUERY - workaround ODBC problems? Are there any settings in SQL Server 2000 (2005 Express) that could help? Are there any settings in ODBC DSN that would help?
regards
arno

I'm trying to use linked server to import big amount of data(around 9 million rows) from mysql to a sql 2005 table.
I plan to create a stored procedure and use job agent to run it at off-peak time everyday. The SP is like:
.....
Truncate table sqltblA;
Insert Into sqltblA(col1, col2, col3)
Select col1, col2, col3
From OpenQuery('mysql', 'Select col1, col2, col3 From mytblB')
.....
But when I tried to CREATE the above SP from management studio, seems the sql server was trying to get all data from table mytblB and ended up with failure after several minutes hang. The error message is sth. like "running out memeory". BTW, during that several minutes hang, I can't query mytblB using mysql's tool as well. it seems to me that table got locked.
However if i try to change the returned result to 100,000 rows by changing script to
Insert Into sqltblA(col1, col2, col3)
Select col1, col2, col3
From OpenQuery('mysql', 'Select col1, col2, col3 From mytblB Limit 100000')
The SP could be created without any problem and running the SP could get the data in table sqltblA.
But that's not what I want, I need all rows instead of a certain amount of rows.
Does anyone know what's going on there when I try to CREATE that SP and any solution to it?
Plus I tried to use SSIS as well. When I'm configuring the DataReader source, which uses ADO.NET's ODBC option to connect to mysql, if its sqlcommand is "select * from mytblB" without the Limit key word, then the configuration page will hang there as well and table mytblB is not accessible by using mysql tool. I'm just sick of wasting time on that and that's why I chose to use SP istead of SSIS. But same result. :-(

Is it that I have a syntax error in the nested OPENQUERY or is there another issue? Do I need to specify a different provider in the Server Link such as OLEDB? Non-nested OPENQUERYs work fine.
I'm generally following theTips and Tricks article.
"Executing predictions from the SQL Server relational engine". One problem is the sample doesn't actually complete the example query after the second nested OPENQUERY call.
e.g.
SELECT * FROM OPENQUERY(DMServer,
'select €¦ FROM Modell PREDICTION JOIN OPENQUERY€¦')
The SQL Server server link's provider is configured to allow adhoc access. I appears that the inner OPENQUERY cannot be prepared by Analysis Server or the Server link provider? but I need to return a key value t.[CardTransactionID] for joining to SQL Server data elements.
OLE DB provider "MSOLAP" for linked server "DMServer" returned message "Errors in the back-end database access module. The data provider does not support preparing queries.".
Msg 7321, Level 16, State 2, Line 2 An error occurred while preparing the query
SELECT * FROM OPENQUERY(DMServer,
'SELECT
t.[CardTransactionID],
t.[PostingDate],
[Misuse Abuse Profile].[Even Dollar Purchase],
PredictProbability([Misuse Abuse Profile].[Even Dollar Purchase]) AS Score,
PredictSupport([Misuse Abuse Profile].[Even Dollar Purchase]) AS Suppt,
t.[BillingAmount]
FROM
[Misuse Abuse Profile]
PREDICTION JOIN
OPENQUERY([Athena Dev],
''SELECT
[CardTransactionID],
[PostingDate],
[BillingAmount],
[AccountNumber],
[SupplierStateProvinceCode],
[MerchantCategoryCode],
[PurchaseIDFormat],
[TransactionTime],
[TaxAmountIncludedCode],
[Tax2AmountIncludedCode],
[OrderTypeCode],
[MemoPostFlag],
[EvenDollarPurchase]
FROM
[dbo].[vMisuseAbuseProfile]
'') AS t
ON
[Misuse Abuse Profile].[Account Number] = t.[AccountNumber] AND
[Misuse Abuse Profile].[Supplier State Province Code] = t.[SupplierStateProvinceCode] AND
[Misuse Abuse Profile].[Merchant Category Code] = t.[MerchantCategoryCode] AND
[Misuse Abuse Profile].[Purchase ID Format] = t.[PurchaseIDFormat] AND
[Misuse Abuse Profile].[Transaction Time] = t.[TransactionTime] AND
[Misuse Abuse Profile].[Tax Amount Included Code] = t.[TaxAmountIncludedCode] AND
[Misuse Abuse Profile].[Tax2 Amount Included Code] = t.[Tax2AmountIncludedCode] AND
[Misuse Abuse Profile].[Order Type Code] = t.[OrderTypeCode] AND
[Misuse Abuse Profile].[Memo Post Flag] = t.[MemoPostFlag] AND
[Misuse Abuse Profile].[Even Dollar Purchase] = t.[EvenDollarPurchase]
')
In desparation I tried returning the case key (CardTransactionID) and the predictive column elements but I get an error when I try that. I assume this is a no-no?
OLE DB provider "MSOLAP" for linked server "DMServer" returned message "Error (Data mining): Only a predictable column (or a column that is related to a predictable column) can be referenced from the mining model in the context at line 2, column 15.".

gave an error:
' msadora reported an error
ole/db returned a message Oracle client & networking component were not found ..'
Any ideas? Should we have a Oracle for Win 2000 CD. It worked for SQL2000 on Winnt server.

I've created a stored procedure on several servers. All with the same name and all in a database with same names.
Now I’m trying to execute the stored procedures by executing a script.... I don’t get it to work!
I can execute it successfully by starting it manually:
exec [CIMPDB01CIMT1].zz_am.dbo.usp_SpaceMon
exec [CIMPDB01CIMT2].zz_am.dbo.usp_SpaceMon
and so on..... no problem
But when I try to execute it by using a script (and substitute the instance names with values taken from a table) it won’t:
declare @x int
declare @dbname varchar(500)
declare @SQL nvarchar(600)
set @x = 1
create table #databases
(ID int IDENTITY,name varchar(500))
insert #databases select instancelongname from instances where actief='J'
while @x <= (select max(id) from #databases)
begin
select @dbname = name from #databases where id = @x
print @dbname
select @SQL='exec ' + @dbname + '.zz_am.dbo.usp_SpaceMon'
print @SQL
execute @SQL
set @x = @x + 1
end
drop table #databases
Msg 203, Level 16, State 2, Line 17
The name 'exec [CIMPDB01CIM].zz_am.dbo.usp_SpaceMon' is not a valid identifier.

I setup a linked server with the following server login mapping:
Local login: db1reader
Remote login: db2reader
db2reader is granted to have read permissions in db2.
I created a stored proc p1 using WITH EXECUTE AS 'db1reader'
Inside the stored proc, I access the link server db2 by "select * from db2server.db2.dbo.table"
db1 reader is granted to have EXECUTE permission on stored proc p1. Trustworthy is on in db1.
Then, I use SQL server 2005 management studio to connect to db1 using db1reader account. Try to execute the stored proc p1. It tells me "Access to the remote server is denied because no login-mapping exists."
Then, I launched a new query in management studio, type in the following TSQL
execute as login = 'db1reader'
go
select * from db2server.db2.dbo.table
revert
go
This time, it works without any error.
Then, in the same query window. I delete all my old TSQL statements and execute my p1 stored proc again.
USE [db1]
GO
DECLARE @return_value int
EXEC @return_value = [dbo].[p1]
SELECT 'Return Value' = @return_value
GO
This time, it works.
What did I do wrong?

Hi,
How do you execute 'DBCC' statements or 'EXEC ...' against a linked server (SQL 2000 sp4) ?

i did "Linked server" between To Servers , and it's Working.
---------------------------
For Example :
Server 1 =S1.
Server = S2.
i create table in S1 : name = TblS1
i create same table in S2 : name TblS2
and i create trigger(name tr_cpD) From S1 in TblS1 For send data To TblS2 in S2
/****************** trigger Code ***************
CREATE TRIGGER dbo.tr_cpD
ON dbo.TblS1
AFTER INSERT
AS
BEGIN
SET NOCOUNT ON;
insert into [S2].[dbname].[dbo].[TblS2] Select ID,Name from insertedEND
**************************************************
result is :
Msg 7399, Level 16, State 1, Procedure tr_cpD, Line 14
The OLE DB provider "SQLNCLI" for linked server "S2" reported an error. The provider did not give any information about the error.
Msg 7312, Level 16, State 1, Procedure tr_cpD, Line 14
Invalid use of schema or catalog for OLE DB provider "SQLNCLI" for linked server "S2". A four-part name was supplied, but the provider does not expose the necessary interfaces to use a catalog or schema.
how i can execute this trigger

UPDATE 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

Ok, so these are the facts:
My company wants to implement a BI, the warehousing company we used sold us panorama on sql server. Our database is on oracle.
They were proposing this method:
a) Link oracle server, copy oracle tables to sql database and then build cubes from sql database. The operation will be made only once a day at night.
I don't like it so make it like this:
b) Build cubes directly from linked oracle server. As it is not good to build directly from tables and views (because they could change between processing dimensions), I used materialized views (or snapshots) and some views on slow modifying tables.
Problem:
Oracle snapshots must be refreshed and that is done in oracle with a procedure.
My question is:
How can I run an oracle procedure directly from sql server? I want to create a job that will refresh the oracle snapshots and process analysis database after that.
I know I can use OPENQUERY to return queries from oracle but I want to execute a script.
Solutions?
Another way was by doing it in a command line.
I asume there is an special job feature that can run programs.
PS. posted in another section too

Can the DTS execute SQL task recognize a table in an Access database that is linked from another Access database?
I'm attempting to use a DTS Execute SQL task connected to Access1.mdb to make a new table in Access1.mdb that is using a Subquery from a linked table in Access2.mdb . (I know it sounds convoluded..) Its giving me an error in my FROM clause as if it can't recognize the linked table from Access2.mdb.
The reason why I'm doing this is that I'm not sure how to run an Access make table query from DTS that will overwrite the existing table in Access. I get an error that the table already exists.
Any Help?

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

I would like to backup a database on a remote SQL 2005 server using T-SQL. The local server I want to issue the command from is also a SQL 2005 Server.
Do I need to use the openquery function?
I am doing this as a job step so I will be executing the query from a local server.
I do not want to use a SSIS package.
Thanks
