MS SQL 7.0 To Sybase Via Linked Server With OLE DB
Jul 5, 2001We have created linked servers that connect to Sybase databases using the Sybase OLE DB provider and the Sybase ODBC provider.
The OLE DB provider does not allow the execution of a stored procedure. The message sounds like a permissions issue, but the id specified in the linked server has execute priv. for the stored procedure. It also does not allow the fully qualified name <server>.<db>.<owner>.<obj> to be used.
There are other issues with OLD DB and ODBC.
Anyone have any experiences making MS SQL to Sybase work smoothly?
Linked Server To Sybase 15.5
Jun 1, 2015Cannot create an instance of OLE DB provider "ASEOLEDB" for linked server "[SERVER_NAME]"
The current setup: Our primary database is on Sybase, I needed to extract hierarchical (nested) XML from multiple tables on Sybase. Although Sybase ASE 15.5 has `FOR XML` query capability it does now allow nested XML format. So we used the 'FOR XML', XML functionality in SQL Server (as we had a SQL Server 2008 database available which is used for a smaller system) to query Sybase tables through a Linked Server connection.Our sample nested XML Format is similar to:
<personCol>
<person>
<id>1111</id>
<name>John</name>
<age>21</age>
<sex>M</sex>
[code]....
Creating Linked Server To Sybase IQ
Nov 10, 2006I would like to create a linked server from SQL Server to Sybase IQ. I have created linked servers before so I know how to do that. However, I dont know the specifics of creating a linked server to Sybase IQ.
What are the parameters that are necessary to link IQ to SQL Server. Which Provider do I use? Do I need to install a special driver?
Linked Server Connection To Sybase
Mar 11, 2004Has anyone had problems using an OLEDB linked server connection to Sybase ASE 12.5? I'm having major performance problems when I use string criteria in the where clause. Queries that return 1 row and execute in less than a second using a native Sybase connection take 40 seconds to run using the linked server OLEDB connection. If I use ints in the where clause performance is almost exactly the same between native and linked connections.
Any ideas???

Apr 2, 2008
Hi all,
Iīm trying to create a linked server to a Sybase database (.db file) so i can create some reports in sql 2005 (with Reporting Services and Report Designer). After reading all articles I did the following.
1) Installe Adaptive Server Anyhwere (Interactive Sql) 9.0.2 on the server.
2) Created a USER DSN to the Db file (Control Panel - odbc connections) and it works fine: The Settings for the ODBC are:
ODBC Tab
Data Source Name: dbNOM
Login Tab
Supply userID and Password: (selected)
User ID: DBA
Password: SQL
Database Tab
Server Name: dbNOM
StartLine: C:Program FilesSybaseSQL Anywhere 9win32dbeng9.exe
Database Name: (blank)
Database File: c:Project FolderDataBase.db
As I said, when i go for "test connection", works fine.
3) Sql Management Studio - Object Explorer - Server Objects - New Linked Server, with settings as following:
General
Linked Server: lkDbNom
Server Type: Other Data Source
Provider: Sybase Adaptive Server Anywhere Provider 9.0
Product Name: Sybase
Product Name: dbNom (the dsn name, right?)
Security
Be made using this security context.- Remote Login: DBA; Password: SQL (same as DSN)
All other settings, as default, click in OK and shows no errors (aparently it creates the linked server successfully). But when i try to query the linked server with:
SELECT * FROM OPENQUERY ('SYBASE', 'SELECT * FROM nom_Robot')
And i get the following message:
Msg 102, Level 15, State 1, Line 1
Incorrect syntax near 'SYBASE'.
Even better, if i go to the Object Explorer - Server Objects, i test the connection and itīs ok, but when i try to retrieve the catalog an error displays:
TITLE: Microsoft SQL Server Management Studio

So, i really donīt understand what is missing in my linked server, i tried with MDASQL (OLEDB for ODBC) but it doesnīt even completes to create the linked server.
The database file is ok because, because in another server (one that doesnīt have SQL, only visual studio) i did the following:
1) Installe Adaptive Server Anyhwere (Interactive Sql) 9.0.2 on the server.
2) Created a DSN to the Db file, and it works fine. (copied the db file, so is local, no remote access), exactly the same setting as i did on the sql 2005 server.
3) Created a connection in visual studio 2008 (server explorer - data connections), i can retrieve sdata...but of course the provider is .NET Framework Data Provider for ODBC and i cannot use the same connection string.
Any ideas?
P.S.
Linked Server - Sybase - Error 7399
Jun 26, 2000I am having trouble linking to a Sybase server using the ODBC OLEDB provider, with either the sp_addlinkedserver stored proc, or the "linked servers" wizard in Enterprise manager.
The SQL I am executing is:
/* add server */
exec sp_addlinkedserver
@Server = 'Linked Server Name',
@srvproduct = 'Sybase System 11',
@Provider = 'MSDASQL',
@provstr = 'Driver={INTERSOLV 3.11 32-BIT Sybase};SRVR=servername;DB=targetdatabase;UID=bob; PWD=bob;'
/* create security mapping */
exec sp_addlinkedsrvlogin
@rmtsrvname = 'Linked Server Name',
@useself = 'false',
@rmtuser = 'bob',
@rmtpassword = 'bob'
(Note that this does not use a DSN - I have tried it both ways, but with no joy).
The SQL executes without any errors or warnings. However, when I try to use the linked server connection (eg., visually list the tables available by double clicking the linked server in the Enterprise Manager, or Select * From a table in the Query Analyser) it give the following error:
"Server: Msg 7399, Level 16, State 1, Line 1
OLE DB provider 'MSDASQL' reported an error. The provider did not give any information about the error."
(That is - generic error)
It just seems that I am not putting the connect string components in the right places.
Does anyone have any suggestions on how to set up a linked server to Sybase in this this way?
Many TIA

Instructions For Setting Up A Sybase ASE Server As A SQL Server 2005 Linked Server?
Dec 28, 2005I have a Sybase Adaptive Server Enterprise server which I need to set up as a linked server in SQL Server 2005. The Sybase server is version 12.5.2, and the Sybase ODBC driver version is 4.20.00.67. I have already installed the Sybase client software on the server.
I also created a SystemDSN on the SQL Server to connect to the Sybase server. I tested the connection and it was able to connect.
I ran the following code to create the linked server:
<code>
EXEC master.dbo.sp_addlinkedserver @server = N'LinkedServerName', @srvproduct=N'Sybase', @provider=N'MSDASQL', @datasrc=N'Sybase System DSN', @provstr=N'"Provider=Sybase.ASEOLEDBProvider;Server Name=servername,5000;Initial Catalog=databasename;User Id=username;Password=password"'
</code>
I then ran sp_tables_ex to make sure I could view the tables in the Sybase database. Here is the error message I get:
<code>
OLE DB provider "MSDASQL" for linked server "LinkedServerName" returned message "[DataDirect][ODBC Sybase Wire Protocol driver]Error parsing connect string at offset 13. ".
Msg 7303, Level 16, State 1, Procedure sp_tables_ex, Line 41
Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "LinkedServerName".
</code>
Any ideas what is happening here?
Linked Server From SQL Server 2000 To Sybase 12
Apr 26, 2004:confused:
How do I tap advanced functionality like #temptable and @var from openquery? There is a linked server from SQL Server 2000 to Sybase 12 using Sybase.ASEOLEDBProvider.
Executing an openquery statement from MS SQL will retrieve Sybase data; however, I have no advanced functionality available. When I try to use temporary #tables or declare @vars it returns this error...
Server: Msg 7357, Level 16, State 2, Line 1, Could not process object '…OLE DB error trace [Non-interface error: OLE DB provider unable to process object, since the object has no columnsProviderName='Sybase.ASEOLEDBProvider', Query=…
Linked Server configuration:
Provider options: AllowInProcess is checked
Server options: Collation Compatible, Data Access, RPC and RPC Out are checked
Does anyone have a suggestion or alternative for this functionality? Thank you very much for your input.
Linked Server From SQL Server 2005 (x64) To Sybase
May 24, 2006Hi,
We have been accessing databases on ASE 12.5 (on HPUX) from MS SQL Server 2000 (x32) successfully for years. We do this via linked servers we create on MS SQL Server. When creating the linked server, we would specify the Microsoft OLE Provider for ODBC as the provider, and the data source is the name of a DSN created with the Sybase ASE ODBC driver (4.20.00.67) that points the the HPUX box on which are the Sybase databases.
We have also gotten this to work just fine on MS SQL Server 2005 (x32) Standard Edition SP1. However, we cannot seem to get this to work on MS SQL Server 2005 (x64) Enterprise Edition SP1. The Microsoft OLE DB Provider is not available as an option when creating the linked server on MS SQL Server 2005 (x64). We have tried specifying the SQL Native Client as the provider, but this results in no connection being made and reports the following error:
OLE DB provider "SQLNCLI" for linked server "GCMTESTSQLNATIVE" returned message "Login timeout expired".
OLE DB provider "SQLNCLI" for linked server "GCMTESTSQLNATIVE" returned message "An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.".
Msg 53, Level 16, State 1, Line 0
Named Pipes Provider: Could not open a connection to SQL Server [53].
Do we need to use a different ASE driver when accessing Sybase databases fom the MS SQL Server (x64) platform? Or is there a way to successfully create a linked server on MS SQL Server 2005 (x64) that can communicate with the 32-bit ASE ODBC driver?
Thanks,
Rocco M.
Problem With Sybase Linked Servers
Jan 25, 2008I have two linked servers configured on my server(SQLServer 2000, Win2003). Both are configured to use Sybase ASE OLE DB driver, version 12.5. I have two differen OLE DB Obects configured in Sybase Configuration Manager. One object is configured to point to a Sybase 12.5 server in Boston, the other is configured for a server(same version) in Westboro. I can test connect from the SQLServer machine on each of these, and see that I am connected to each of the Sybase servers. However, my linked servers are only able to connect to the first OLE DB data source listed in the Sybase Configuration Manager. The linked servers are configured to use different OLE DB data sources, and no errors are thrown, but I can see that both actually go to the same data source. If I rename/re-order the OLE DB Data Sources, and make the second one the first one, I can connect to the other server.
Is this a known issue?
We are currently switching over to Sybase ODBC driver(not sure why we used the OLE DB driver in the first place), via which we can connect to both Sybase servers.

What settings or whatever would cause this to take so much longer from the linked server?
Edit:
Note) Other queries from the linked server do not have this behavior. From the stored procedure where we have examined how long each query/update takes... this particular query is the culprit for the time eating. I thought it was to do specefically with this table. However as stated when a query window is opened directly onto that server the update takes no time at all.
2nd Edit:
Could it be to do with this linked server setting?
Collation Compatible
right now it is set to false? I also asked this question in a message below, but figured I should put it up here.

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,

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!
