OpenDataSource Quandary
Aug 17, 2007
I am trying to open and query a Microsoft Access "like" database from SQL Server 2000 using OpenDataSource. This will work for a little while, but if I am to update my ASP.NET code base I have to completely reboot the machine for these queries to work again. I also have two reboot the machine periodically because this functionality decides to crap out. I am doing this from a stored procedure. My code looks like this:
DECLARE @SelectCode varchar(5000)
SET @SelectCode =
'SELECT CONVERT(varchar, Value) AS UnitName FROM
OPENDATASOURCE(''Microsoft.Jet.OLEDB.4.0'', ''Data Source = "' + @Path + @DataFile + '.fcd";User ID=Admin;Password=;'')...Properties WHERE Property LIKE ''UnitName'''
EXEC(@SelectCode)
Now, when I am developing on my local machine that uses Windows Authentication, I have absolutely no problems, unless the source file has a schema error.
Any ideas?

ClientA inv00007
ClientA inv00008
ClientB inv00002
ClientB inv00003
ClientB inv00006

Here's my query:
Select top 500 email, custnumber from MailingList order by email
There may be some duplicate email addresses with different custnumbers. What would the query look like to only show records with unique email addresses, but still return the unique custnumbers in the query.
Thanks in advance.

Hey all, first time poster here.
Cheers!
Enterprise Edition SQL2k sp3a on Win2k3 Enterprise Edition server.
Using BCP to load ~4 million records.
Largest record width is ~350 bytes.
When finished i have over 6 million pages reserved and only about 800 thousand actually used.
Which puts me 'round about 3 rows per page and WAY too much empty space.
YIKES!
Any thoughts as to why this is happening?
Or insight into how BCP handles page allocations that may be different than the typical extent based page allocations for table data?
Thanks!

What is the syntax for using parameters in an opendatasource query? I tried using the below:
SELECT top 10 *
FROM OPENDATASOURCE(
'SQLOLEDB',
'Data Source=10.22.10.78;User ID='+@user+';Password='+@pword
).Northwind.dbo.Categories

Hi all, In a select sql statement, I have to query 2 databases from 2 different servers. The only way I found to do this, is to call OPENDATASOURCE like this :<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:bdConnectionString1 %>" SelectCommand="SELECT * FROM [Table1] t1 left join OPENDATASOURCE('SQLOLEDB','Data Source=servername;Initial Catalog=xxx;Persist Security Info=True;User ID=xxx;Password=xxx').dbname.dbo.table2 t2 on t1.id = t2.id"> </asp:SqlDataSource>My question is the following :Is there a way to connect to the second server without using the full server declaration into the sql statement ? For information, the server connection is already declare into my web.config like that :<add name="bdConnectionString2" connectionString="Data Source=servername;Initial Catalog=xxx;Persist Security Info=True;User ID=xxx;Password=xxx" providerName="System.Data.SqlClient" />so is there a way to use 'bdConnectionString2' directly ?If not, is there a way to connect to the second server without entering informations like User ID and Password ? My problem being that I'm not sure it's safe to send this informations directly from the asp.net page. Thank you

begin
select @datasource = 'Data Source="c:/'
+@FOLDERNAME
+'/'
+@FILENAME
+'";User ID=;Password=;Extended properties=Excel 5.0'
select
*
into
#excel_table
from OpenDataSource( 'Microsoft.Jet.OLEDB.4.0', @DATASOURCE)...sheet1$
end
need to do this ... but using variables in opendatasource not allowed.
so how do we go about it
What i need to do is allow upload of any excel file ... may contain errors and then perform some checks on the data before putting it into another table with a fixed structure.

Hi,
I have written a stored procedure which extracts job history from all our servers using the OPENDATASOURCE function using NT authentication.
It's works fine when the stored procedure is called from Query Analyser, however I want it to be called hourly so are calling it from a SQL agent job.
I have set the job to run as myself, and the owner is myself, but the procedure fails when trying to connect to the first server, giving the error :-
"Executed as user: NT AUTHORITYSYSTEM. about to query : aadmin01 [SQLSTATE 01000] (Message 0) Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection. [SQLSTATE 28000] (Error 18452). The step failed."
It doesn't seem to be able to make the NT authenticated connection when the OPENDATASOURCE function is called from within the context of a SQL agent job.
I know a solution may be to use a regular SQL login for the OPENDATASOURCE calls, but this means hard-coding passwords into the stored procedure - I'd read this is bad practice.
Any thoughts appreciated.
Thanks

Does anyone know if OPENDATASOURCE or OPENROWSET can be called via NT authentication, rather than with a SQL Login? If so, what would be the correct syntax to use?

Ok .. Gurus ... here's my problem
I am able to successfully run a opendatasource query against a flat file from SQL Server. However the problem I am facing is that the resultset that is returned has a line as one column and one row ... is there any way i can get the opendatasource query to recognize tabs as column seperators ????

Hi folks.I'm trying to connect to a Medisoft Advantage SQL db through SQL Serverusing OpenDataSource or OpenRowSet. I have general connections to the dbworking fine, but not with OpenDataSource or OpenRowSet.I've tried variations on:select * fromOpenDataSource('Advantage OLE DB Provider','Data Source=C:MediDataTutormwddf.add;User ID=user;Password=password;Advantage Server Type=ADS_LOCAL_SERVER;Initial Catalog=mwddf.add;')...MWPATWhich gives:OLE DB error trace [OLE/DB Provider 'Advantage OLE DB Provider'IColumnsInfo::MapColumnIDs returned 0x80040e21: [COLUMN_NAME=TABLE_CATALOGORDINAL=-1], [COLUMN_NAME=TABLE_SCHEMA ORDINAL=-1], [COLUMN_NAME=TABLE_NAMEORDINAL=-1], [COLUMN_NAME=TABLE_TYPE ORDINAL=-1], [COLUMN_NAME=TABLE_GUIDORDINAL=-1]].I've also tried:select * fromOpenrowset('Advantage OLE DB Provider','Data Source=C:MediDataTutormwddf.add;UserID=user;Password=password;Initial Catalog=mwddf.add;Advantage ServerType=ADS_REMOTE_SERVER',MWPAT)and 'Select * from MWPAT'.These last yield:[OLE/DB provider returned message: No Data Source specified]which seems closer.Can anyone help? I think this is all Advantage-specific. I've posted ontheir boards, but their not very active...Thanks.David

I would like to create a stored procedure that imports an Excel file toa sql server table. I need to be able to pass the path to thespreadsheet to the stored procedure like so:CREATE PROCEDURE dbo.ImportSpreadsheet(@Path nvarchar(120))ASSELECT * INTO AuditFROM OPENDATASOURCE( 'Microsoft.Jet.OLEDB.4.0','Data Source = ' + @Path + ';Extended Properties=Excel 8.0')...Audit$I will call the stored procedure from within my .NET application andpass it the path as @Path. The path will be chosen by the user at runtime and will be something similar toC:SpreadsheetsAudits.xls.I can make this run in the Query Analyzer:SELECT * INTO AuditFROM OPENDATASOURCE( 'Microsoft.Jet.OLEDB.4.0','Data Source = ''C:SpreadsheetsAudits.xlsAudit_TC.xls'';Extend edProperties=Excel 8.0')...Audit$I could run the SQL directly from my app, but I like to use storedprocs whenever I can for the speed and flexibility. I can change thestored proc and not have to recompile/reinstall the app.Any help would be greatly appreciated.

Hi All
I'm trying to update feilds in a local table from a remote table using the following:
update schema.table1 set acc = r.acc, add = r.add
from OPENDATASOURCE('SQLOLEDB','Data Source=10.10.10.171;User ID=user;Password=mypw').db.schema.table1 as R, schema.table1 as L where R.acc = L.acc
When run from Query Analyser, it fails with:
Could not find server '"db"."schema"."table1" in sysservers. Execute sp_addlinkedserver to add the server to sysservers.
On both servers, the database, schema and table names are the same.
Running SQL2K SP4 on both servers. Don't want to set up linked servers, as they will only connect on a scheduled basis to perform updates.
Other queries such as insert work, as well as update OPENDATASOURCE( . . .) set x=L.x from schema.table where . . . so it's a prob with the From clause of the update.
Am I missing something, or is what I'm trying to do just not possible?
TIA

I have the following T-SQL commands which run without errors:
select Description_Text
from OpenRowset('MSDASQL', 'Driver={Microsoft Text Driver (*.txt; *.csv)};
DefaultDir=D:Import;','select * from company_finance.csv')
select Description_Text
from OPENDATASOURCE('Microsoft.Jet.OLEDB.4.0',
'Data Source=D:Import;Extended Properties="Text;HDR=Yes;FMT=Delimited"')...company_finance#csv
When I run either command on our TEST server, all the text in the fields retrieved is returned, but when I run on our PRODUCTION server, all fields are truncated to 255 characters. The source file company_finance.csv is identical on both servers. Both servers have the same O/S (Win 2K Server), same version of SQL Server 2000 and MDAC (2.71). I cannot figure out if the problem is on the SQL Server side, or has something to do with some registry settings or something else, but both the Text Driver and the Jet drivers produce the similar results on each servers. Are there some config settings in SQL Server or in the registry I can look at to determine why the truncation is occurring? Help!
Thanks for your time.

Greetings all
Have another issue with OPENDATASOURCE
The following SQL appears to run successfully:
Update OPENDATASOURCE('SQLOLEDB','Data Source=10.10.10.171;User ID=*****;Password=******').TRANSFERSTN.TSADMIN.SALESDAY
set STARTDTTM = L.STARTDTTM,ENDDTTM = L.ENDDTTM,CLOSED = L.CLOSED,
CASHEDUP = L.CASHEDUP,CASHINTILL = L.CASHINTILL,CHEQUESINTILL = L.CHEQUESINTILL,
EPSALES = L.EPSALES,EPCUTORETURN = L.EPCUTORETURN,REPFLAG = R.REPFLAG
from OPENDATASOURCE('SQLOLEDB','Data Source=10.10.10.171;User ID=******;Password=*****').TRANSFERSTN.TSADMIN.SALESDAY AS R inner join
TSADMIN.SALESDAY as L on R.SALESDAYID = L.SALESDAYID where L.REPFLAG = 1
However, all records in the remote table get updated if there are any records satisfying the REPFLAG clause, if more than 1 then I guess the last record in the source set.
Running the same SQL against 2 tables in the local DB works perfectly.
These are both MSDE V8.00.2039 SP4 connecting via RAS dial up.
Any ideas where to focus my attention will be gratefully received
Thanks
<EDIT>
Haven't solved the issue, but staggered around it. I have simply reversed the tables in the SQL and executed at the remote server instead, so it is updating a local table while getting data from a remote table. This functions as it should. Any clues to the above would still be good tho' - cheers

Hey guys. I got some problem here.
I have an Excel spreadsheet. the data is something like :
COL1 COL2 COL3
DATA1 1 DETAIL1
DATA2 2 DETAIL2
DATA3 3 DETAIL3
DATA4 4 DETAIL4
DATA5 5 DETAIL5
DATA6 6 DETAIL6
DATA7 7 DETAIL7
etc
there are 1877 * 3 cells in total in the spreadsheet.
but when I execute a query like:
select * from OpenDataSource('Microsoft.Jet.OLEDB.4.0','Data Source=Test.xls;User ID=Admin;Password=;Extended properties=Excel 8.0')...[Sheet1$]
It returns 2132 * 5 units of data!!! And the "F4" and "F5" column just have NULL. so do row 1878 to 2132. I'm confused with that.
I need your help~ 3X in advance. :)
