Data Source Name Not Found And No Default Driver Specified
Mar 12, 2007
I know this may be a simple problem, but here it is:
I have SQL server express installed on Windows 2003 server (Testing) it works fine;
When I move it to my production server (Windows 2003) I get the error message"Data source name not found and no default driver specified "
The system DSN in ODBC connections works fine, or at least completes the test ok.
My application is written in Classic ASP
PLEASE HELP
Thanks

trying to install sql server2005 on a windows 2003 server box.
getting msg below at the sql server . i looked at other posts on trying to uninstall SQL Native Access Client and norton antivirus. i could never find the snac on the add - remove programs and this server does not have a virus protection program yet.
here's the history of the installs on the server:
wanted to test a 2005 upgrade so:
1) installed sql server 2000 then sp4 then restored some databases to it - all OK
2) tried to upgrade to sql 2005 but ran into problems and left it at that.
had a disk drive crash on the d drive so lost the installs but not the operating system
when the drive was replaced, left alone for a while
then wanted to test a straight 2005 install
1) removed the broken 2005 attempt
2) removed the 2000
3) installed 2005 and got the error on the subject line:
TITLE: Microsoft SQL Server 2005 Setup
------------------------------
SQL Server Setup could not connect to the database service for server configuration. The error was: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified Refer to server error logs and setup logs for more information. For details on how to view setup logs, see "How to View Setup Log Files" in SQL Server Books Online.
i've gone through as many of the forums that i can and have tried several things - like uninstalling 2005 and installing pieces and parts but but nothing seems to work.
Thanks!

i am attempting to run phpbb using ms sql 2005 on the same box but get the following error during the setup
Could not connect to the database, see error message below.
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
i am not sure yet if this is an issue with sql, php or phpbb
php is installed in iis and has all the modules installed which the php msi installer supported. i can run php code but in this case when i'm running the install.php file for the phphbb setup, i fill in the values for the database and got that error
phpbb detects all the required server settings and sees that i have ms sql installed
any suggestions on what that error means or how to go about configuring odbc driver?
probably a simple issue. but i'm still new with sql stuff

Hi all,
We are using a package to extract data from a source build on some image using SOLID ODBC 5.2 driver.
When we tried to extract data through MS SSIS(SQL Server Integration Services) package using SOLID 5.2 ODBC driver connection, it throws an error as mentioned below:
ERROR DESCRIPTION:
Error: 0xC02090F5 at Data Flow Task, DataReader Source [1]: The component "DataReader Source" (1) was unable to process the data.
Error: 0xC0047038 at Data Flow Task, DTS.Pipeline: SSIS Error Code DTS_E_PRIMEOUTPUTFAILED.
The PrimeOutput method on component "DataReader Source" (1) returned error code 0xC02090F5. The component returned a failure code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing. There may be error messages posted before this with more information about the failure.
Error: 0xC0047021 at Data Flow Task, DTS.Pipeline: SSIS Error Code DTS_E_THREADFAILED. Thread "SourceThread0" has exited with error code 0xC0047038. There may be error messages posted before this with more information on why the thread has exited.
Also, we tried the same in a Excel sheet using the SOLID 5.2 ODBC driver it is working fine.
Does the SOLID ODBC driver support .Net framework or do we need to install any other components??
Thanks and Regards,
Nirmal

I have this Stored Procedure:

When I execute it in the SQLExpress, the result returned as expected. But when I bind to Gridview I got this error:
A field or property with the name 'Jan' was not found on the selected data source.
How do I solve this?
I am using drag and drop SQLDatasource to call the Stored Proc and VB.net is the language. Thanks

I have a custom folder layout for reporting services on our test environment so each tester can test the reports against the data in their own instances. The developers have reports in a different layout that's more in line with what will be in production. So I figured some simple RS scripting would handle things.
It was easy to create the folder structure, easy to create the shared data sources in each testers reports folders, and easy to deploy the report from the developers folder (source) to the testers report folders. However, when I try to use SetItemDataSources to change the data source in the newly duplicated reports, I keep getting an error telling me that the data source cannot be found.
Here's the relevant code fragment:
'Set report DataSource references
Dim DataSources(0) As DataSource
DataSources(0) = New DataSource
' update with new data source info
DataSources(0).Name = strDSName
Dim Item1 as DataSourceReference = New DataSourceReference
Item1.Reference = strRef
DataSources(0).Item = Item1
Console.WriteLine( "Setting report {0}, data source to {1}", strTargetReport, strRef)
RS.SetItemDataSources( strTargetReport, DataSources)
strDSName is "OLTP", strRef is the path to the shared data source, "/Reports/Tester1/Data Sources/OLTP". strTargetReport is the name of the report itself, full path name to "/Reports/Tester1/Report1".
Each tester has their own folder off the main reports folder "Reports", with an incremental number, as in "Tester1". Each testers folder has it's own Data Sources folder. There is only one data source for all reports, "OLTP".
/Reports
/Reports/Tester1
/Reports/Tester1/Data Sources
/Reports/Tester1/Data Sources/OLTP
/Reports/Tester1/Report1
/Reports/Tester1/Report2
I even went into SQL Server Management Studio and tried changing the (now broken) data source setting for a report to point to the correct data source (OLTP), then copied the generated script, then ran it - and still got the data source cannot be found error. That's what my latest code shown above was based on.
Anyone got any clues?
Thanks,

I am testing an application that uses mysql that works 100% fine with Microsoft Windows XP on Windows Vista Premium Home Edition.
Using Vista's ODBC Data Source Administrator I have set up and successfuly tested the DSN Connection to the Database.
However, when I call the set up DSN with the application I get [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified.
I am using the mysql-connector-odbc-3.51.12-win32.
I have tried editing the registry DSN files - the problem still persists.
Does anybody know a way to solve this problem

I was working for 2 days on integrating reporting services with MOSS 2007.
The problem i faces was to create a data source for the
uploaded report (Not created using a wizard ) that will connect
me to the SQL server.
As i clicked on the arrow near the uploaded report to manage the data source, i found no
data source for this item.
I would be pleased to know the howto create this data source and where.
Best Regards,

Hi SQL Server Team,
In order to add a data source by using ODBC Administrator, programmatically i am using SQLConfigDataSource. Thus calling SQLConfigDataSource with the fOption set to either ODBC_ADD_DSN for creating a new DSN.
Following is the stattement specified in the source code. where type_of_driver = "Microsoft Access Driver (*.mdb)"; and parameters contains the data source source credentials information such as DSN, UID, PSW, FIL, Description, DataDirectory,DEFAULTDIR and DBQ all separated by " ".
rc = SQLConfigDataSource(NULL, ODBC_ADD_DSN, type_of_driver, parameters);
after execution of below mentioned command an error is encountered i.e -1 is returned if the DataDirectory path exceeds certain nested directories link. for eg. the file path specified below.
C:My DocumentsClients CurrentAHW Netcare BenefitsDeliverables1-5 Results Chain - system LevelAlberta NetcareBenefits Logic System Level V01.rcm
Creating a datasource with the file name i.e Benefits Logic System Level V01 every time.
rc = :: SQLConnect(hDbc, (unsigned char *)szSource, SQL_NTS, (unsigned char *)szUserName, SQL_NTS, (unsigned char *)szPassword, SQL_NTS);
Also following error message was encountered during execution of SQLConnect command.
/*szErrorMsg = 0x0012e834 "[Microsoft][ODBC Microsoft Access Driver]General error Not enough information to connect to this DSN with SQLConnect. Use SQLDriverConnect."*/
Thus followed the instruction smentioned in the error message an dtried using SQL DriverConnect() in the following manner.
rc = :: SQLDriverConnect(hDbc, NULL,(SQLCHAR *)"DSN=RCM",SQL_NTS,outstr, sizeof(outstr),
&outstrlen,SQL_DRIVER_NOPROMPT);
Still an error is encountered but this time it returns a RETCODE of 100 whrease earlier it had returned -1.
Inform the procedure to be followed using SQLConnect when DataDirectory path is too long.
An early reply will be appreciated.
Cheers & Regards,
Saresh

Hello Everybody,
I have a problem that when I insert a date 06.04.2007 on my
computer it is interpreted in European style (meaning: dd/MM/yyyy)
and the same code on another computer is interpreted in American
style (MM/dd/yyyy). So on one computer 06.04 means 6th on April, and
on others 4th of June. The question is how can I programatically set
that all the SQLDataSources (or en every one of them separately) take
the date from the text box in one or the other way – not depending
on local settings (it does not matter for me too much which one -
just so that it always works the same way. It would be better for me
to use European style though).All the best,Joseph

I have two instances in SQL on my machine. When creating a New Data Source in BIDS, I can only see the default instance. I have checked the SAC manager to make sure the second instance allows remote connections and the setting are exactly the same as the default. Any ideas? Thanks.

I have several versions of SQL Server and have been using SQL 2008 on a regular basis due to this issue. Our SQL 2014 when I do the Import Data process, it opens up the dialog window, hit next, and the data source is currently defaulting to ".NET Framework Data Provider for IBM i" - when it does this it immediately errors out with:
"An error occurred which the SQL Server Integration Services Wizard was not prepared to handle.
Additional Information:
> Exception has been thrown by the target of an invocation (mscrolib)
>> Failed to find or load the registered .NET Framework Data Provider (System.Data)"
It immediately crashes/closes the Import/Export wizard with me unable to change the data source to what I need it to be.
My 2008 defaults to SQL Server Native Client 10.0 and does allow me to change to that same option (at which point it errors) but it does not close the wizard.
I need a way to either:
> Default the starting Data Source to be something else
> Fix whatever error is causing it to crash - I am at a loss as to what the error is looking for
> Not have the wizard crash whenever it defaults to this source.
Any of the above solutions would work fine - but at the moment I am unable to use the Import/Export wizard at all in SQL 2014.

Hi,
I'm running W2K3 SP1. The MDAC Configuration Checker reports MDAC 2.8 SP2. The only discrepancy is MSADCO.DLL, where the expected version is 2.82.1830.0 and my actual version is 2.82.2651.0 (svr03_sp1_gdr.060301-1546).
The error message I'm getting when I use the ODBC Administrator dialog to set up a new entry is: "The setup routines for the SQL Server ODBC driver could not be found. Please reinstall the driver."
This is followed by a dialog titled: "Driver's ConfigDSN, ConfigDriver, or ConfigTranslator failed." The body text of the dialog is "Component not found in the registry."
Does anyone have any idea how I can repair this?
Thanks,

I have tried my best and not able to locate the source of this error.
The error logged in Event Viewer shows the source is from MSSQLServerOLAPService, but it is impacting the Reporting Services reports that use the Analysis Services as a data source to hang frequently.
Have anyone else encounter this and know what the Category 256 Event ID 22 means?
I am using SQL 2005 RTM MSAS and MSRS.

Good morning,
I have written a package which accepts variables for the server, initial catalog & table name.
I execute sql to drop the following stored procedure, then following sql statement to create it.
================================================================
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE procedure [dbo].[SP_CreateMatchProc]
@sTable varchar(300)
as
BEGIN
SET NOCOUNT ON
declare @cmd nvarchar(2000)
set @cmd = ''''
Set @cmd = 'SELECT REPLACE(field1 + field2 + field3 + field4 + field5, '' '', '''') AS dBString '
+ 'FROM ' + @sTable + ' ORDER BY <table>_ID COLLATE Latin1_General_CI_AS'
exec (@cmd)
END
GO
================================================================
Then in the Oledb source (validateexternalmetadata = false) I use "sqlcommand from variable" with a variable value of "SP_CreateMatchProc '<tableName>'"
The package runs fine in the IDE regardless of variable values, but when I created a batch file which calls dtexec I get a failure:
Error: 2007-10-04 08:46:42.82
Code: 0xC0202005

Code: 0xC004701A
Source: Data Flow Task DTS.Pipeline
Description: component "OLE DB Source" (310) failed the pre-execute phase and returned error code 0xC0202005.
End Error
with the ValidateExternalMetadata set to TRUE I get
Error: 2007-10-04 09:21:35.20
Code: 0xC004706B
Source: Data Flow Task DTS.Pipeline
Description: "component "OLE DB Source" (10621)" failed validation and returned validation status "VS_NEEDSNEWMETADATA".
End Error
the most notable thing I see there is that it looks like a different ID (310) with out the validation and (10621) with it.
Any help would be greatly appreciated.

I am trying to use a DTS package to extract data from an old Pervasive SQL 2000 (Btrieve) data source, and copy into an MS SQL Server table.
I have installed the Pervasive ODBC driver and got linked tables in Access working. I can see the data.
When I create the DTS package, it shows a list of the tables in the drop-down, but when I hit the Preview button I get an unspecified error. I can finish setting up the DTS package, the new MS SQL Sever table gets created, and the field transformations all look correct. However, when I execute the package it fails. In the logs, I get an unspecified error, the only error code I get in log is: 80074005.
Please help.
Thanks!

Hi
In this code how can I create a new data source and new data source view and model and structure that it run dynamic.
In this code I have a lot of errors, that they are about server and database don€™t have in current code,
In this code, first I should definition server or no?
Database dbNew = new Database (databaseName,
Utils.GetSyntacticallyValidID(databaseName, typeof(Database)));
srv.Databases.Add(dbNew);
dbNew.Update(true);
***********************************************************
How can I create data source and data source view and model and structure?
Please say code of that, and guide me.
databasename and srv is unknown.
Do I add other reference with analysis services?
Please explain about these codes:
************************************************************************
1)
RelationalDataSource dsNew = new RelationalDataSource(
datasourceName,
Utils.GetSyntacticallyValidID(

*************************************************************
4)
// Make sure we have the name we thought
dss.Tables[0].TableName = tableName;

ms.Source = new DataSourceViewBinding(dsv.ID);
ms.CaseTableName = "Customer";
Add columns:
ScalarMiningStructureColumn smsc;
// From table "Customer" we will add a couple of columns
// CustomerID - key
smsc = new ScalarMiningStructureColumn("Customer ID",

I have set up a new connection as a connection from data source, but I cannot see how to use this connection to create my Data Flow Source. I have tried using an OLE DB connection, but this is painfully slow! The process of loading 10,000 rows takes 14 - 15 minutes. The same process in Access using SQL on a linked table via DSN takes 45 seconds.
Have I missed something in my set up of the OLE DB source / connection? Will a DSN source be faster?
Thanks in advance

Today I was making a few reports.
When I tested the reports in Visual Studio, they worked great: I got the expected result.
But when I deployed the reports to our reportserver the problem started.
When I click on the directory in which my reports are deployed, I got my 4 reports.
Till now everything worked correct.
But when I click on a report to view the results it went wrong.
I got an error:
"Cannot create a connection to data source 'Live'"
(Live is the name of our data source).
We are using the Windows Logons and I am sure that I have all the rights on the server, I gave myself 'sysadmin' rights, so it should work.
I also have tried it with all the roles assigned on my account, but then it still won't work.
When I modify the data source, and set it to another server en database it works.
The datasource 'Live' exists on a x64 MsSQL server, en the other datasource is on a x86 MsSQL server.
Maybe that is the problem?
Can someone tell me what is wrong?

I was trying to load data using SSIS, Data Flow Task, OLE DB Source, source was a view to a OLE DB Destination (SQL Server). This view returns 420,591 rows from Query Analyzer in 21 seconds. Row length is 925. When I try to executed the Data Flow Task from SSIS, I had to stop the process after 30 minutes, because only 2,000 rows had been retrieved. I modified the view to retun top 440, 000 and reran. This time all 420, 591 rows were retrieved and written in 22 seconds. Next, I tried to use a TOP 100 Percent. Again, only 2,000 rows were return after 30 minutes. TempDB is on a separate SAN Raid group with 200 gig free, Databases on a separate drive with 200 gig free. Server has 13 gig of memory and no other processes were executing.
The only way I could populate the table was by using an Execute SQL Task and hard code an Insert into table selecting data from the view (35 seconds) from SSIS.
Have anyone else experience this or a similar issue? Anyone have a solutionexplanation?

Hi there,
I am trying to use the new ListView control in VS2008 in an ASP.Net app. My problem starts already with the datasource. I drag and drop a SqlDataSource and select
Microsoft SQL Server Compact 3.5 (.NET Framework Data Provider for Microsoft SQL Server Compact 3.5)
I can connect to the database and test the query in the wizard (I do not need to use a password??)
This is the webconfig entry
<add name="ConnectionString" connectionString="Data Source=C:Program FilesMicrosoft SQL Server Compact Editionv3.5SamplesNorthwind.sdf" providerName="Microsoft.SqlServerCe.Client.3.5"/>
I add the following line in the page load event
AppDomain.CurrentDomain.SetData("SQLServerCompactEditionUnderWebHosting", true);
However I get the error message that the data provider cannot be found and it might not be installed. I added the reference and also gave the folder above ASP.NET full access rights.
Anyone else encountered this problem. It is quiet strange? Thanks a lot for your help.
Cheers,
Chris

I am trying to combine 2 tables, one is an event table, the other is a system table.
I would like to update field system.transaction with the first event.transaction
Where event.account = system.account
and event.effdt > system.effdt
and event.effdt <= system.effdt + 30
It's not really a join so I'm not sure how to write it.
Thanks,
Doug

Hi all, this is REALLY weird, I can t seem to make heads or tails of it. but from my understanding the each datatype has set contrstraint assigned to it ( example int datatype can only except non-decimal numeric values ) as well as a datetime datatype can only except a vaild date.
Though oddly i have found the following dates in a table ( in addtion the when aby kind of data operation is performed on the table sql returns the following error:
Server: Msg 8630, Level 16, State 1, Line 1
Internal Query Processor Error: The query processor encountered an unexpected error during execution.
Here are some of the dates that were present in the table:
DateColumn1
-----------
1900-01-01 857:44:45.813
1900-01-01 872:51:16.427
1900-01-01 872:54:57.440
1900-01-01 873:09:32.107
1900-01-01 873:13:10.560
1900-01-01 873:16:49.867
1900-01-01 888:27:00.640
DateColumn2
---------
-22063-05-18 00:00:00.000
-20285-02-03 00:00:00.000
In addtion there were some other columns that have had odd data in them(VERY WEIRD)
Char25Column
---------
ÃQ307000
ÃQ307000 ÃQ307000
ÃQ307000
ÃQ307000
Any Thoughs?
Thanks

HI All,
I have created around 150 reports using SSRS. I just made a new data drive subscription(file sharing) using report manager. Now I'm wondering is there any option to make subscription at the higher level? That means instead of subscribing one report by one report , can I do it at the folder lever using report manager without writting a programm?
Thanks
