SQL 2012 :: Linked Server To CSV File
Aug 5, 2014
I upgraded my 2008 R2 instance to 2012 and the Linked Server I use for aconnect to a csv file stopped working.
Create script:
EXEC sp_addlinkedserver @server ='Stats_CA',
@srvproduct='',
@provider ='Microsoft.ACE.OLEDB.12.0',
@datasrc='D:RLAPPSStatsStats_CA',
@provstr='Text'
Error message:
OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "Stats_CA" returned message "Unspecified error".
Msg 7303, Level 16, State 1, Line 2
Cannot initialize the data source object of OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "Stats_CA".
I uninstalled and reinstalled the AccessDatabaseEngine - no change.
The provider is displayed, so it's not that.
I verified temp and csv location folder permissions
I tried the -g512 startup option
The csv has a schema.ini as required
It was an 'in place' upgrade, so nothing else has change.

I have a 3rd party dashboard application that I can only use SQL authenticated logins to connect to the database.
I'm trying to create a query within the application that will directly access an excel file through a linked server.
As a test, I login to SSMS as the sql auth user to run the linked server query below but the following error is returned:
select *
from Corporate...[Sheet1$]OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "Corporate" returned message "Cannot start your application. The workgroup information file is missing or opened exclusively by another user.".
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "Corporate" reported an error. Authentication failed.
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "Corporate".
When I login as a Windows auth user, I can successfully run the above query.
I noticed within the linked server's security definition that I cannot specify a windows auth user as the mapped Remote User or as the Remote login
I've tried creating a Credential object with the identity of the windows user and assign that object to the sql auth user but to no avail. I still get the same error
I am using SQL Server express so the option of an automated server agent job to import the excel file is not available.
Details:
SQL Server Express 2012
Office version: Excel 10
Provider: Microsoft.ACE.OLEDB.12.0

I am currently trying to optimize an ETL process that pulls around 150 tables from a OLAP-esque system through a linked server. It's the AllScripts Touchworks EMR database, if that makes a difference. I am having a difficult time fitting an incremental load into a reasonable window of time. For instance, one table, which has around 40 columns, and a total of about 50 million rows, takes around an hour just to pull one day's worth of records when filtering on a single datetime field. The query is:
SELECT *
FROM OPENQUERY([linkedserver],
'
SELECT *
FROM Works.dbo.Visit
WHERE StartDttm BETWEEN ''2014-12-23'' AND ''2014-12-24''
'
)
Which, in the end, returns only about 30k records. However, in trying different approaches, I decided to test out bcp using the following code:
bcp Works.dbo.Visit out f:etlvisit.dat -n -S linkedserver.this extracted the entire table to flat file, but it only took about 15 minutes....add on another 3-4 to load that into the database on my end. Now, my ability to see what's happening on the remote server's end is very limited, but I know that the server has much higher specs than mine. They have 96GB memory vs. my 32GB, twice the cores I've got, etc. So how is this running faster by pulling the entire table over?
I figured that even in the worst case scenario of a full table scan, picking 30k rows out of the table that match a single criteria would certainly run faster than bringing the whole thing over. This isn't isolated to a single table, either. I finished running a test of the incremental extract/load vs. full extract/load via bcp (200GB of data). The incremental takes about 7 hours, bcp takes about 2 hours.

I have a system where people can apply for registration and also a registration fee is involved. The screen where the application is captured has a couple of inserts into different tables. Each of these tables have triggers on them to transfer data to a linked server and they work fine. Today I just added another trigger on a different table but also part of this same save process. Now I am getting the following error:
Microsoft OLE DB Provider for SQL Server error '80004005'
The statement has been terminated.
/orisys.int.za/applicants/ApplicantInsert.asp, line 111
I do not know this error and think it might be time-out.

I have created a linked server that point to a firebird database, everything is fine, I can query the database with something like
Select * from MYLINKEDSERVER...MYTABLE
Now , can i use tablediff utility with this linked server. If yes, any example ..
I would say also that performance is not very important to me. this would be used at the end of the day to make some sort of replication by generating a sql script with datadiff, and run it on a local sql server database and a web based SQL database. The replication is not an option since i am using a shared web hosting and replication is disabled on it .

I have a SQL Server 2012 instance set up with a linked server to an Oracle Database. I need to build a stored procedure (single NVARCHAR(6) parameter in: @accountID) which executes a select statement against the Oracle DB.
Everything's working fine when testing with 'EXEC (''<oraclecodeblock>'') at LINKEDSERVERNAME' if I hard code the value of @accountID in <oraclecodeblock> but when I encapsulate it all within sp_executesql and attempt to parameterize @accountID it's throwing ORA-01722 'invalid number' errors on the Oracle DB. The parameterized value is NVARCHAR as are the account numbers.
Working:
DECLARE @accountID VARCHAR(6);
SET @accountID = '10842';
DECLARE @sql NVARCHAR(MAX);
SET @sql = N'EXEC (''SELECT * from A.Accounts WHERE ID = ''''10842'''';'') AT LINKEDSERVER';
[code]...

How do you name sql linked-servers in your company ?
we have many legacy systems (random naming), but mostly newer systems follow this pattern
<ENVIRONMENT><APPLICATION><FUNCTION><VIRTUAL><NUMBER>
e.g.
PRD-FAX-DB-V01, TST-PAY-WEB-P02 etc.
We have link-servers all over the place. The ideal naming convention should satisfy following:
- developers should not have to modify code when deploying between environments DEV->TEST->PROD. This rules out using actual server name as linked-name.
- the name should easily identify actual server without much mental translation. This rules out relevant but generic names like FAXSERVER or PAYSERVER
- also, if the name could state that it is a linked-server e.g starting with LINK_, it works when reading the code.
So, I was thinking the link-name should simply remove the environment :
e.g LINK_FAX_DB_V01
that way, on DEV box, the underlying sql data source could point to the dev server, while on test, it could point to test server etc. without having to change code, and also knowing which server it's pointing to by just adding a TST or PRD in front-of it.

I wonder if it possible to move data from tables on a linked server to a "normal database"?
Name linked server: Covas
Name table on linked server: tblCountries
Name field: cntCountryName
Name "normal" database: CovasCopy
Name "normal" table: Countries (or dbo.Countries)
Name "normal" field: Country
This is just a test setup. I figure that if I get this working the rest will be easier.
My current query:
select * from openquery(COVAS,'
INSERT INTO CovasCopy.dbo.Countries(Country)
SELECT cntCountryName FROM db_covas.tblCountries;')

I've got an OLEDB DB2 linked server to a db2/AS400 instance and selecting from a table on the server has never caused problems before. One of the columns is a large text field. If I select all the columns but the large text field, it returns as normal, but including the large text field now, I get:
"Transport error: shared memory provider error: 0 - no process is on the other end of the pipe"
The largest entry in the text field is about 5k characters, and there don't appear to be any strange characters.

As a database developer, I have so many databases that I "own" scattered across various servers that it''s getting difficult to remember where all of my databases reside. It doesn't work that the DBAs have taken to some very hard to remember server naming conventions.
I was going to create aliases via the configuration manager, but it turns out the DBAs overwrite my entries each night with THEIR aliases and they won't add any for my use.
So I decided to simply add some records to my host file so that instead of having to connect to "SERVER-AD_DADF-DAFDASS" I can just use "CustomerA".
This solution seems to work until I tried to access a linked server. If I connect to the main server via it's actual name, I can hit the remote/linked server with no issue. However, if I connect to the main server using it's alias, connection to the remote/linked server fails with: Login failed for user 'NT AUTHORITYANONYMOUS LOGON'.
The linked server is set up to use current security context and I'm not logging into the alias any differently that I do when using the actual server name.

I'm having a few issues trying to get a linked server setup from a new SQL2012 installation to a Lotus Notes database. This linked server has previously been working fine on our old SQL2005 environment. All setup using the same details (ODBC driver name matches, account details etc). If we test the connection from the Lotus ODBC driver the test connection is successful, If I then create the Linked server to access this ODBC driver I receive an error :
Cannot initialize the data source object OLE DB Provider "MSDASQL" for linked server "LotusTest"
OLE DB provider "MSDASQL" for linked server "LotusTest" returned message "[Microsoft][ODBC Driver Manager] Driver's SQLSetAttr failed"
OLE DB provider "MSDASQL" for linked server "LotusTest" returned message "[Lotus][ODBC Lotus Notes]
Unable to find path to server. check your network connection is working.(Microsoft SQL Server, Error: 7303)We have just migrated to a SQL Server 2012 64 bit Enterprise from SQL Server 2005 32 bit Standard. We have a 64 bit Lotus client installed to provide the correct ODBC driver which has enabled the test connection direct from the ODBC driver to connect successfully. I'm just at a loss as to how to resolve this issue and get the linked server connecting.

I have a situation that I need to add a field to a table over linked server. The specifications of this is dynamic and it is being done in TQL / Stored procedures and this can not change. My code is generating the statement just fine and if I copy paste it to a new SSMS window and execute it WORKS.. The problem is I need to dynamically generate the statement (I am doing that just fine, I THINK). THEN I need to execute the statement IN THE SPROC, this part is not working.
Here is the code:
SET @AlterSQL = @DestinationServerName + '.[' + @DestinationDBName +'].' + @DestinationSchemaName + '.sp_executesql N'' ALTER TABLE '
+ @DestinationTableName + ' ADD ' + @TempColumn + ' int' + CHAR(39)
The above Creates this when I expose it via a PRINT statement:
addb15.[FSParallel].dbo.sp_executesql N' ALTER TABLE Node ADD ImportIdentity int'
After I create the statement I use:
EXEC @AlterSQL
And this returns the following error:
Msg 2812, Level 16, State 62, Procedure ETLDynamicImport, Line 244
Could not find stored procedure 'FSParallel.dbo.sp_executesql N' ALTER TABLE Node ADD ImportIdentity int''.

Linked Server File DSN?
Can anyone help? I am trying to connect a Domino Server with the NotesSQL ODBC.
I was unable to set the ODBC up as a System DSN ('The setup routines for the
Lotus NotesSQL Driver (*.nsf) ODBC driver could not be loaded due to system error
code 126') and had to set it up as a file DSN.
Can I still set up a Linked Server to it? I keep getting errors:
'7399 Invalid Connection String attribute]
(not sure what I was supposed to enter in the 'Product String' dialog box)
Datasource name not found and no default driver specified]....'
The file DSN was setup OK. I know this because I can use it as a connection in
DTS and successfully import various tables (although it does not work with the
import wizard?)
Does anyone know if I can use the file DSN to setup a linked server?
If so, what do I put in the 'provider string' and 'catelog' dialogs.
Any help much appreciated. wyatt.anderson@nwmhp.nhs.uk

I am trying to link an excel file as a linked server. I tried two methods unsuccessfully.
first: using
EXEC sp_addlinkedserver 'Ex',
'Jet 4.0',
'Microsoft.Jet.OLEDB.4.0',
'c:list5.xls',
NULL,
'Excel 5.0'
GO
When I run
EXEC sp_tables_ex Ex, I get the error below.
Server: Msg 7303, Level 16, State 2, Procedure sp_tables_ex, Line 20
Could not initialize data source object of OLE DB provider 'Microsoft.Jet.OLEDB.4.0'.
[OLE/DB provider returned message: Cannot start your application. The workgroup information file is missing or opened exclusively by another user.]
Second: I link the excel file using ODBC datasource:
EXEC sp_tables_ex mylink, works fine with mylink being the linked server name. I get the table names eg. table1$, table2$.... However when I try to query the tables, I get this error:
Server: Msg 7313, Level 16, State 1, Line 1
Invalid schema or catalog specified for provider 'MSDASQL'.

In Oracle when i create any procedure i define parameter datatype linked to under lying table.
For ex
create procedure testprocedure
(param1 customer.name%type,
param2 customer.salary%type )
Here i have defined param1 and param2 with datatype of name and salary of customer table respectively.
This way i do not need to worry about modifying param1 and param2 datatypes when datatypes of name & salary of customer table changes in future.
How can i accomplish this in SQL server.

Here is my Problem:
1. I have sql 2008 R2 running on my LocalHost.
2. Created Data Base [Customer].
3. Created Linked Server [CUSTOMERLINK] USING Microsoft Jet 4.0 to link to Drive F:Data which has DBF files in it.
4. Create dbo.Customer_Upload Table.
5. INSERT INTO [Customer].[dbo].[Customer_UpLoad]
([Name],[Email])
SELECT
NAME,EMAIL
FROM [CUSTOMERLINK]...[CUS]
All this works fine. I can even put it in to an After Insert Trigger on another table and it works.
My problem is that I need this to work in a scheduled job.
F:Data is just a folder with files in it.
This info is from a Restaurant POS system and I need to update it every night.
I have tried every which way to to setup the security issue as there isn't any login security on the folder and SqlServerAgent wants security.

Hi
I am having an Access database on a shared network drive which has read/write access rights on the that shared network drive.
When I try to Access data through the linked server it gives me gives me a message box saying you do not have permissions to view the data.
Also if i try to use xp_cmdshell to copy over the mdb file to my local drive it say 'Access denied'
But when I copy (through command prompt) the same file to another network drive or my local drive where I have full control the linked server can connect sucessfully.
The problem is the i cannot have 'full control' permissions on shared drive where my database resides.
Has anybody encountered this problem....
Any help will be greatly appreciated.

Hi All,
I have this very big text file (2.5 GB - which of course I am not able to open). This resides on a server which has SQL 2005.
I have created a linked server for this text file on my SQL database, and when I try to query the table, I get an error:
Cannot initialize the data source object of OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "txtsrv".
Why am I getting this error? When I make a dummy linked server on my local machine and test the steps it all works OK. but when I go to this server where the file and it's SQL instance is lying, I get this error. Please can someone provide me with some help on this?
Many thanks,
~S
P.S. Here is how I created the linked server (I also have the Schema.ini lying under the same folder):
EXEC sp_addlinkedserver txtsrv, 'Jet 4.0',
'Microsoft.Jet.OLEDB.4.0',
'C:SSAnalysis',
NULL,
'Text'
