Limited stored procedure support when using Linked Server with MSSQL Server and ASEOLEDB

When using the SAP Sybase ASE OLE DB Provider you are able to create linked servers in MSSQL Server (2005, 2008, 2008 R2, 2012) to access remote data sources such as SAP Sybase ASE 15.7. In principle you create a linked server on the MSSQL Server, using the SAP Sybase ASE OLE DB Provider, or ASEOLEDB in short. From a connection on the SQL Server you can run various queries to access the data.

One thing that comes up from time to time is to access stored procedures on the ASE. One convention well known in linked server is to call the stored procedure using the four part naming convention:

EXEC Linked_Server_name.database.schema.stored_procedure_name

For example, if I created a procedure in the pubs2 database:

create proc sp_authors (@p1 varchar(50))


select * from authors where state = @p1

I call it from a connection via a tool like isql:

1> sp_authors ‘CA’

2> go

au_id       au_lname                                 au_fname

         phone        address

         city                 state country      postalcode

———– —————————————- ——————–

         Oakland              CA    USA          94618

I get back all the records where state is ‘CA’.

On linked server I create linked server named PVLNX1570, which will access my ASE 15.7 on Linux, and I configured it to connect to the pubs2 database. When I use the four part naming convention to execute from a tool like the query tool in the Microsoft SQL Server Management Studio:

PVLNX1570.pubs2.dbo.sp_authors ‘CA’


Msg 7212, Level 17, State 1, Line 1

Could not execute procedure ‘sp_authors’ on remote server ‘PVLNX1570’.

This type of call isn’t supported from Linked Server when the data source isn’t SQL Server. I found this link from the SQL Server documentation:


2008 R2:

Guidelines for Using Distributed Queries

Under Other Guidelines it states:

Stored procedures are supported only against SQL Server data sources.

There is a way to get around this in using the EXEC command. There are many ways to use the command and Microsoft in its wisdom provides a means to call the remote SQL directly with the linked server:

2008 R2:

The syntax is as follows:

EXEC (‘sproc plus parameters’) at Linked_Server_name

For the above sample:

(‘sp_authors ”CA”’) at PVLNX1570

au_id au_lname au_fname phone address city state country postalcode

And there you have it. For sure, if you develop applications and are used to using the four part naming convention, and who wouldn’t since it is a normal convention, this dilemma poses a difficulty and challenge. However, due to this situation you can get around it by using the variation of the EXEC command. The nice thing here is the linked server doesn’t send extra metadata calls during the execution, it simply sends the command as is and let’s the backend do the work, delivering the desired results.

      Hi Paul,

      I found this article on your ISUG blog. Thanks for reposting, I would have never found it. I have a (probably stupid) question regarding this. Do the ASE client tools have to be installed on the SQL Server machine? If so do you think that will resolve the error I'm getting below?

      I set up the linked server using the following procs: sp_addlinkedserver, sp_addlinkedsrvlogin and sp_serveroption. I see my linked server with sp_linkedservers. I created an ODBC connection on my machine that points to the ASE server and it successfully connects.

      I call a remote proc like so:

      exec ('sp_get_branch_info ''0221'', ''CORPORAT'', ''MAILING''') at testdb14

      I get the following error:

      Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "testdb14".

      Thanks again,

      ASE SDK 15.7 software definitely needs to be installed where MSSQL Server
      lives. The server requires the backend drivers to access the backend (ASE in
      this case).


      You mention you make an ODBC connection to the ASE? What exact driver (you can get driver name from the ODBC Admin tool)?

      The error:

      Cannot initialize the data source object of OLE DB provider "MSDASQL" for
      linked server "testdb14".

      tells me you are using an ODBC data source (testdb14) to connect to ASE from linked server. We recommend the use of the ASE OLEDB Provider to do this.


      The weird thing about linked server is it doesn’t always provide good messages.


      Show me the parameters use for the sproc calls to create the linked server.


      What MSSQL Server version?

      What Windows machine (version and whether 32 or 64-bit)

      I will see if I can get the SDK installed on the SQL Server box.

      I'm using the ASE driver v15.7.0.80 odbc version 03.51. I've setup both 32 and 64 bit.

      sp_addlinkedserver @server = 'testdb14', @srvproduct = 'Ase', @provider = 'MSDASQL', @datasrc = 'testdb14'

      sp_addlinkedsrvlogin @useself = 'false', @rmtsrvname = 'testdb14, @rmtuser = 'mdl', @rmtpassword = '******'

      sp_serveroption @server = 'testdb14', @optname = 'rpc' @optvalue = 'true'

      sp_serveroption @server = 'testdb14', @optname = 'rpc out' @optvalue = 'true'

      Microsoft SQL Server 2012 - 11.0.2325.0 (X64)

      Win7 64b

      Thanks again,

      Hi Mark,

      You're using the 15.7 GA version. I am not sure how you get the ASE SD.  But this shoul dbe okay to start but might be better if you can get a current release (15.7 SP122).

      What you are showing me is using the ASE ODBC Driver (Provider = MSDASQL is the MDAC bridge to bridge the oledb calls to odbc api calls). I suggest you use the ASEOLEDB (The OLE DB Provider) as the provider.  You can use the Data Source tool found under the Sybase folder on the machine to create a data source for the OLEDB Provider and see if it will work.  We encounter issues with using ODBC driver under linked server and Engineering isn't able to really fix too many issues there but will provide support using OLEDB for linked server when it comes down to it.

      Hey Paul,

      I created the OLE datasource and changed the provider to ASEOLEDB. Now I'm getting the message: The OLE DB provider "ASEOLEDB" has not been registered. I don't see any Sybase related names in the provider folder so I suspect that is because the pcclient isn't installed on the server.

      They are getting a Java invocation error when trying to install the pcclient on the server box. The server is running the Windows Server 2012 operating system. It apparently doesn't like the Java install.

      I feel like we're making progress we're just not quite there.

      Hi Mark,

      Where is this pcclient from - what distribution? I am thinking maybe from the ASE developers edition? Or something else? Can you download the SDK from either old Sybase or SAP site - assuming you have licensing for ASE?

      Also, maybe we could do this through email - I can't reply to your emails from this posting so maybe send your email address and we could communicate that way?

      Sounds like this pcclient isn't liking to install on windows 7, but I usually don't see problems with installing the 15.7 client software on windows 7.

      The pcclient comes from "Adaptive Server Enterprise 15.7 PC Client CD". The SDK he has tried to install comes from a zip file named I updated my last post to say the SQL Server is running Windows Server 2012. My development machine is Windows 7. Sorry if I misled you earlier.

      My email is mlibnerAtYahooDotCom

      Hi Mark,

      PC-Client 15.7 base has issues installing on Windows 2012, this was not certified with Windows 2012 Server. You need to get EBF21161 PC-Client 15.7 SP100. Even with that version there was issues with the odbc administrator crashing with our odbc driver. So you would have to install SDK 15.7 SP110 or higher on top of the PC-Client.

      So your best bet is if you can get SDK 15.7 SP122 EBF 22089 and just install this and don't worry about the PC-Client 15.7 part unless you need Interactive SQL(DBISQL). They pulled Sybase Central out of the PC-Client 15.7 SP100.

      So basically get SDK 15.7 SP122 and install this.

      Hi Dawn,

      Thanks for the info! We will download and install sp122 and see if that is the silver bullet.

      Thanks again,
