Sybase and SQL Server almost have same set of commands till SQL Server 2000 and Sybase versions till that.

Anyhow FYI, Nolock is discontinued from SQL Server 2005 onwards.

Im pulling my data from sybase into SQL Server 2000 using a linked server. My code looks like this

select * from openquery(LinkServer,'select * from sybasetable WITH( NOLOCK )')


however i am getting an error

[OLE/DB provider returned message: [Native Error code: 156]
[DataDirect ADO Sybase Provider] Incorrect syntax near the keyword 'WITH'.
]
OLE DB error trace [OLE/DB Provider 'Sybase.ASEOLEDBProvider' IColumnsInfo::GetColumnsInfo returned 0x80004005:   ].
Msg 7399, Level 16, State 1, Line 1
OLE DB provider 'Sybase.ASEOLEDBProvider' reported an error.

Try using without WITH (NOLOCK) keywords and tell me the results.

Kindly check whether the login used for Linked Server Creation has select rights on that table.

How about we start with the Sybase product (there are at least 4) and the complete version (e.g. ASE 12.5.3).

My guess is that you are using ASE, not ASA which is why the ASA-only "NOLOCK" qualifier is not working.

Bill

No.  NOLOCK is not supported by ASE.

What version of ASE?
Do a "SELECT @@version" and post the results.

Hmmm.  If you can't get something simple like SELECT @@version" to work, I am guessing there is something wrong with your linked server / OLE DB setup.

You will have to go straight to the server to get the version information.

What kind(s) of thing(s) are you doing that are causing locks on the table(s)?

Also, what is the overall project requirement?  It may be possible to do something that doesn't have all the limitations and issues associated with a linked server.

Regards,
Bill
