An Error When Instantiating C#-based COM Object In OLE DB Provider Linked To SQL Server Express
Aug 24, 2007
Hi,
I'm working on an OLE DB provider. This provider is supposed to retrieve data from managed application running in background. The data retrieval is handled by C# component communicating with source application via remoting, the data are then exposed via component's COM interface. OLE DB provider itself instantiates the communication component.
Now, the problem: this worked ok in SQL server 2000, but it doesn't seem to work in SQL server express edition. Concretely, the communication component fails to get created (CoCreateInstance ends with 'class not registered') and SQL server logs this:
2007-08-24 14:48:49.42 spid51 Error: 6511, Severity: 16, State: 20.
2007-08-24 14:48:49.42 spid51 Failed to initialize the Common Language Runtime (CLR) v2.0.50727 with HRESULT 0x80131022. You may fix the problem and try again later.
I've googled a bit and found out someone else getting this message, and he was told something like 'trying to load CLR in some cases is disabled in newer (>2000) versions of SQL server'.
Now, I have very little knowledge of SQL server, CLR integration etc., so I'm not sure whether this applies to my case as well, but I think so - that problematic COM object is C#-based.
I'd be glad for any hints, ideas how to solve this issue, I just need the OLE DB provider to be able to access that managed application.
I have two servers, DEV and PROD. Now my DEV server works just great, I can connect to the linked server, query, etc... all is well.
So I'm setting up my PROD server and when I go to add the linked server I get:
Cannot initialize the data source object of OLE DB provider "SQLNCLI".... and Unable to complete login process due to delay in opening server connection.
Now I am running SQL Server 2005 and connecting to an SQL 2000 server.
The odd part is that this works just fine on DEV.
When I go to create the linked server I set:
Linked Server: "LinkedServerName"
Server Type: "SQL Server"
and that's it.
I go to Security and enter my DOMAINUSER.ACCOUNT and then enter the login creds for the linked server.
When I click "OK" I get the above mentioned error code.
3.Create linked server with scripts: exec sp_addlinkedserver N'MyOracle1', 'Oracle', 'ORAOLEDB.Oracle', N'//10.154.14.235', N'FetchSize=2000', '' exec sp_addlinkedsrvlogin @rmtsrvname='MyOracle', @useself=N'FALSE', @rmtuser=N'root', @rmtpassword='Sqlexp!23' Â Â 4. After create successful and testing the connection ,I got the error below.(My windows firewall is turn off)
An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)
Cannot initialize the data source object of OLE DB provider "ORAOLEDB.Oracle" for linked server "MyOracle".OLE DB provider "ORAOLEDB.Oracle" for linked server "MyOracle" returned message "ORA-12504: TNS:listener was not given the SERVICE_NAME in CONNECT_DATA". (Microsoft SQL Server, Error: 7303)
This is a problem that never get solved, sometime I can use other way to avoid it, but havn't found a solution yet, i hope I can get some more idea here.
I am using SQL 2005, when I run
select * into #import1 from OpenRowSet('microsoft.jet.oledb.4.0','Excel 8.0;hdr=yes;database=\ws8webjeff2.xls', 'select * from [jeff2$]')
I get
Cannot initialize the data source object of OLE DB provider "microsoft.jet.oledb.4.0" for linked server "(null)".
when I try to compile a SP with that statement in it, I get the same error, like
create stored procedure test
as begin
select * into #import1 from OpenRowSet('microsoft.jet.oledb.4.0','Excel 8.0;hdr=yes;database=\ws8webjeff2.xls', 'select * from [jeff2$]')
end
so it seems the error may not relate to the real file, since at the compile stage, it should not check the real file?
On my live db, after I restart the SQL service, the statement will work, after a while, one or several days, I get the same error again. I can not restart my live db quite often for sure, so now I have another backup db server, I need run the statement on the backup server and then read the data from there.
I have the same problem at two places, both use SQL 2005.
So far there are three questions
1, why it works after restart, but only last for a while? something about memory? since the backup db seldom need restart and work fine after many days.
2, why it gives error in compile stage?
3, why two dbs in different Enviroment has the same problem
The most answer I have gathered so far is permission issue, true I got similar error if the import file is located in a place which SQL has no right to access. But in this case, it should not be.
Hi,I have SQL Server Express Edition. I tried working out some ASP.NET Labs in my local system. Here is the link of the Virtual Lab which I tried. http://msevents.microsoft.com/CUI/WebCastEventDetails.aspx?EventID=1032286906&EventCategory=3&culture=en-US&CountryCode=USI recieve this error in my local system. 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. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)I tried working out solutions from various websites. But the no solution is effective. Could anyone help me in solving this issue.
I want to create a table in MS-Access. So I have written the following query.
Code Snippet select * from Openquery(KKACC, 'select * Into Temp from Table select 1 as col1')
But I am getting the following error.
Code Snippet
OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "KKACC" returned message "Syntax error in FROM clause.". Msg 7321, Level 16, State 2, Line 1 An error occurred while preparing the query "select * Into Temp from Table select 1 as col1" for execution against OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "KKACC".
How can I resolve this error. Does any one have any work arround for this..?
We have a SQL2005 server install running on a Win2003 Server. It has a linked server to iHistorian using the iHOLEDB provider for iHistorian. Randomly and after a few execution to this provider, we start getting errors
Msg 7303, Level 16, State 1, Line 2
Cannot initialize the data source object of OLE DB provider "IhOLEDB.iHistorian" for linked server "fspheafhs1".I created a data source in VS2005 for BI on the SQL server using the iholedb provider. This was successful. However, all queries or OPENQUERY statements to the linked server fail. This seems to continue until SQL Server is restarted. Does anyone know how to reset a provider in SQL Server or tell if the SQL Server is having trouble with the provider? There are no message in the SQL Error Log. Again the provider continues to work outside of SQL Server, but no longer can be accessed from within SQL Server. Thanks in advance.
Hallo i'm trying to connect a VFP DBC as a linked server on MSSQL2000sp3a, using following parameters:
Product name: VFP
Data source: \networkpath odbc
Provider: VFPOLEDB.1
No security context I'm trying the same operation both from a W2000sp4 server (+ MDAC 2.8sp1 ?) and a WXPPsp2, against two identical copies of the DBC that resides on two different path (one on the final path and one on a test path). From WXPPsp2 everything runs ok, from W2000 i'm always getting this error: Error 7399: OLE/DB Provider 'VFPOLEDB' IUnknown::QueryINterface returned 0x80070005: Access Denied (already reported in this thread, http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1832362&SiteID=1 but it didn't helped me)
The error happens independently from the user the query runs under (basicly AD account, both domain admin and normal user). MSSQL runs under a domain account which have full permissions (for test purpose) on the directories where DBC reside.
I did no further modifications on the WXP machine in order to have the linked server running, simply it ran smoothly from the beginning.
Clearly the difference rely on the different OS... but what else?
i ran component checker to determine the MDAC version but some components version numbers slightly differs from the expected ones (eg. resulting version is 2.0.1064 versus 2.0.1022 expected in MDAC 2.8) so i suppose to have MDAC2.8 sp1 on the server. thanks in advance
I'm currently having an issue with a linked server. Here's the surrounding information:
A) I have a clustered SQL Server 2005 Instance (A) and a SQL Server 2000 instance (B). B) There is a linked server on A to B. When I set it up, I did run the fix to ensure A could talk to B (There was an issue with communication between 2005 and 2000 servers). It has been there since I installed A, and has worked fine.. Until last week. C) This linked server uses static credentials to connect to B. D) Named Pipes are enabled on both servers to listen to both connections on both A and B in cliconfg. So A has a named pipe listening for B, and B has a named pipe listening for A. E) A has a view that looks at a table on B - It's a table view, very simple, just pulls in all the data from the table on B.
So, I go to do a select statement from the view, connected as a user other then 'sa'. I then get the error:
Named Pipes Provider: Could not open a connection to SQL Server Linked Server Error Source: ncli Client (Paraphrasing, didn't copy that down, but it was the ODBC connector)
Well, that's odd. It's been working fine for months now..
I then go and connect as sa on A to query B. It works! Mind you, absolutely NO QUERY from A to B will run again until I run SOME kind of query has been run as sa on A.
Mind you, this is not a credential issue. Every user who connects to the linked server to B uses a stored credential that is DBO to the database on B. The same User Name and Password exists on both A and B.
Also of note, I check the activity monitor. There's a process that is "dormant" every time I run a query against the view. The details of this connection are:
sp_reset_connection;1
My question is, why is it resetting the connection on B when being queried from A? Why is it "all of a sudden" a problem? Are there any changes that coudl ahve been made that would cause this?
Any help with this confusing issue would be appreciated.
I just installed a SQL Server 2005 Express SP2 instance on a server with an existing SQL Server 2000 SP3 installation. (I need SQL Server 2005's INSERT from an EXEC capability). It's working great now except for one thing: I can't link any other SQL servers! I've already successfully added and queried a linked Oracle server, but attempting to add a linked SQL server gives me the following error, no matter which SQL provider I try to use:
Code Snippet "The linked server has been created but failed a connection test. Do you want to keep the linked server?" Additional information: --> An exception occured while executing a Transact-SQL statement or batch (Microsoft.SqlServer.Express.ConnectionInfo) --> Cannot create an instance of OLE DB provider "SQLNCLI" for linked server "SERVERNAME". (Microsoft SQL Server, Error: 7302)
The technical details reveal the error source as "sp_testlinkedserver".
I've scoured the net and premier support for advice on this problem, but the little I found wasn't helpful. I've tried reinstalling the SQL Native Client, but it didn't help. I've tried uninstalling SQL Server 2005 Express completely (including management studio and native client), rebooting, and reinstalling everything, with no luck. The server (obviously) does not have a firewall enabled. I've tried stopping the SQL 2000 Server installed on the system, no help. If I create a test .UDL file on the system, pointing to any of the SQL servers I'm trying to link, clicking the "Test Connection" button returns successful. I'm also able to connect to and query the servers directly from the SQL 2005 Express Management Studio. I just can't add them as linked servers.
The server is running Windows 2003 SP1, SQL Server 2000 SP3, and SQL Server 2005 Express SP2 (the default "SQLExpress" named instance). I've tried setting up SQL 2005 Express to run under the network service account and under a domain account used by the other SQL 2000 servers.
From other SQL 2000 servers, I can connect and link to the SQL Server 2005 Express instance successfully. I can also successfully add linked SQL servers in SQL Server 2000 instance installed on the same server. Only adding linked SQL servers in 2005 Express seems to be broken.
Anyone have any other suggestions? I'm totally baffled. Thank you so much for any helpful advice.

In case if anyone has a solution to it, please let me know.

I just installed the latest VS 2008 C# Express and SSCE 3.5. I am trying to test the "LINQ to SQL" feature. I added a data connection to Nortwind.sdf, selected "Microsoft SQL Server Compact 3.5 (.NET Framework Data Provider for Microsoft SQL Server Compact 3.5)" as data provider, tested the connection, and get the following error when I drag and drop the "Customers" table on the design surface "The selected object(s) use an unsupported database provider" ?. I can create new tables and view existing tables etc. except droppinjg it on the design surface. What am I doing wrong?
The installation on my WindowsXP machine went without a hitch.

I am very frustrated. Everything works on the local host but when I upload to server I can login to the admin role I created, but when I try to access pages that have role priveleges I get the following error: The SSE Provider did not find the database file specified in the connection string. At the configured trust level (below High trust level), the SSE provider can not automatically create the database file. The ASPNETDB.MDF database was uploaded using the Database Publishing Wizard. Please help!
Basically the error that I am getting is in our test automation when running as non-admin on the box (regular user). We use .Net C# SQLConnection class to connect to SQL express 2005 impersonating with admin credentials. After getting the connection we try to execute a select command and it some time fails with following error: A transport-level error has occurred when receiving results from the server.

I have a dataflow task. On which I have OLEDB as my source. I connect to my database and execute a stored proc. the stored proc results in a result set with only one row and two columns. First Column is an integer and the second row is a varchar(max) with xml script in it. Not that it should matter because it is in varchar(max).
Anyway, it give me an error
[OLE DB Source [321]] Error: A rowset based on the SQL command was not returned by the OLE DB provider.
What am I doing wrong?
Can I not have a stroed proc that returns a result set as my data source?
