ODBC Connection Issue On Client Site
Jun 7, 2007
Hi,
It might be a basic question but could you please help me on that?
Working Environment:
I have developed application on SQL Server 2005 and now wants to Run on Client Site, I am using access as a front end and SQL server 2005 back end through ODBC (System Dsn) which is working good. (user has been added on SQL Server and on Database)
Question:
1) Do I need to create new System Dsn Or other DSN (Keep in mind I have already create System DSN in Server) at each client site to access application from Server?
(If yes then I am trying to do that, it allow me to create (with required database which is on Server) and verify but doesn€™t save on ODBC list so I can€™t use that name to run appliation on client site)
I am using windows authentication.
Thanks for help in advance

I apologize if this is not the correct forum for this posting. Looking at the descriptions, it appeared to be the best choice.
I am running Windows XP Pro SP2. I have installed the SQL Native Client for
XP. However, when I try to add a new data source through ODBC Connection
Manager, SQL Native Client is not listed as an option. I have followed this procedure on three other systems with no problems. What would be causing the
SQL Native Client to not show up in the list of available ODBC data sources?

Hi All,
I've developed an application that connects to a SQL Server 2005 Express database. I created a DSN to connect to the database through ODBC. Currently, I am testing locally and everything works fine.
I would now like to install my application on another workstation and connect remotely to the database located on my development machine.
The client workstation does not have SQL Server 2005 Express installed on it because I would just like my application to connect remotely by creating the DSN and using ODBC. What I'm missing here are the database drivers. The "SQL Natice Client" is not available on this client workstation. How can I deploy the necessary drivers with my installation file so that I may create the required DSN name using the SQL Native Client driver?
Thanks!

We have set up Mirroring with a witness server and everything works fine when we failover from the SQL Management console.
However, if we failover when our Maccola client is connected, the client blows up - clearly because it can no longer connect to the database.
The ODBC DSN used by the Maccola client shows a checkbox for the 'select a failover server' but the checkbox is grayed out.
Also the summary of settings for the DSN at the end of the wizard reveals that the failover to server (y/N) option is set to N.
The default setting for this DSN is 'populate the remaining values by querying the server' but it doesn't appear to be getting the settings for failover from the server or any other interactive DSN settings either. The server is clearly set for mirroring.
Another suspicious item is that the DSN cannot connect to the server with SA permissions, even though the server is set to mixed security and we use the correct authentication.
Is it possible that the client MACHINE is not authenticating with the domain or sql server properly. We are logged into the client with the domain account that is the SQL admin account on the sql server box.
We should be able to interact with the sql server settings through the ODBC DSN on the client shoulnd't we?
Are we missing a service pack on the client?
Thanks,
Kimball

On Windows XP systems I get the following issue when trying to browse the MSDB folder in SSIS
Client unable to establish connection
Encryption not supported on SQL Server. (Microsoft SQL Native Client)
I have noticed another post where several others have noticed the same issue. It appears to only occur on Windows XP installations. Is there a workaround or fix for this?

I am using SSIS 2014 with the below .net framework version and installed in Windows server 2012 R2 . I have installed my client's odbc drivers (both 32 bit and 64 bit) in my production server and created ODBC system DSNs for 32 bit and 64 bit.
When i open SSIS 2014 and tried to create the odbc connection but i can able to see only the 32 bit system DSN connection ,i can't able to see my 64 bit odbc system dsn connection.

And i installed my client odbc drivers(32,64 bit) and created ODBC system DSNs in my local system and when i open ssis 2014 and i can able to see both the ODBC system DSNS(32,64) connections from SSIS ODBC connection.
I am using below version of .net framework in my local system which was installed in windows 7 and i have SSIS 2012 also installed in my system and i can able to see both ODBC connections using 2012 as well in my local system.

I have tried this on several different operating systems (VISTA and XP ) and several versions of SQL NATIVE CLIENT including 2005.90.3042.0
I have a 64 bit "SQL NATIVE CLIENT" connection that fails. The exact same connection and code succeeds on 32 bit.
My customer and I prepend "oledb:" to the connection string and it starts working.
FAILS on 64 bit:
Provider=SQLNCLI.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=Wrigley_Test;Data Source=MONGO;Use Procedure for Prepare=1;Auto Translate=True;Packet Size=4096;Workstation ID=RIPTIDE;Use Encryption for Data=False;Tag with column collation when possible=False;MARS Connection=False;DataTypeCompatibility=0;Trust Server Certificate=False
WORKS

I debugged my code to the point that I know it is happening when I call CreateAccessor for my SQL statement.
m_hr=m_pIAccessor->CreateAccessor(DBACCESSOR_ROWDATA, GetCols(), (m_pDBBinds+IsBookmarked()), 0, &m_hAccessor, NULL);
Error:
Microsoft SQL Native Client: Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.
Does anyone have any suggestions?

As a SQL adminstrator any maintenance I perform including performing full database backups against the sql server with users connected to a certain database, causes the odbc connection to fail between the web server and the sql database. This causes all clients to experience an odbc failure. The only resolution is to reboot the webserver. There is ODBC driver incompatibilites that exist between the servers. Does anyone have any suggestions? I am in the process of a change control request to upgrade the ODBC on the production SQL server to 3.70.0623 the same as the web server but am not sure that this is the issue. Can there be something in the application itself that would be causing it to break and not reestablish the ODBC connection?
Thanks

I have an application on:
W2K client
Sql 2000 + No SP
MS ODBC V3.8
C++
The application, running on the client, connects to SQL server for many simultaneous queries involving select, insert and update. Application creats a thread for each query. Each thread connects to the sql server via ODBC using sqlconnect.
However I find that the individual thread do not close properly and stay open even after sqldisconnect has been issued on the client. At one point I have over 1200 threads on client application trying simultaneously to connect to the server and the sqlserver is holding with 276 threads open.
I do not understand why the ODBC connection stays open even after sqldisconnect is issued. I have even tried disabling connection pooling, to no effect. The performance is very poor.
How can I issue a large number of queries to same sql server via ODBC while guaranteeing performance?

Hi all,
I followed an excellent tutorial (from Microsoft) about creating and using a SQLExpress db table internal to your website and the site I created works just fine - locally. When I publish to my web host provider I get this error:
[SqlException (0x80131904): 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)]
My web host provider supports .NET 2.0 but doesn't support MS SQL Server. But that should matter - right? Because I'm putting the db instance right in the website?
I did a search and followed some of the advice:
I went into the SQL Server Surface Area Config Mgr and set SQLExpress for local and remote connections and rebooted/republished. I also have SQL Server 2005 installed as a separate entity (if that makes a difference).
I still get the above error. This is the connection string from the web.config:
<connectionStrings>
<add name="ConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Customers.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
</connectionStrings>
And this is the call from the markup:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT * FROM [Customer]"></asp:SqlDataSource>
Does any know the fix for this?
Thanking you in advance
Pat

We've run into an issue running against the SQL Native Client ODBC driver (version 2005.90.2047.0) on Windows 2003 Server (Itanium). The "INFO: ODBC 64-Bit API Changes in MDAC 2.7" article (http://support.microsoft.com/kb/298678) doesn't say that the returned value for SQL_ATTR_CONCURRENCY changed to a 64-bit value, but if you request this attribute from the SQL Native Client driver, a 64-bit value is returned. The ODBC spec still indicates that SQL_ATTR_CONCURRENCY is a SQLUINTEGER value, which is 32-bit, even on a 64-bit platform.
This is easy to see by using the ODBC Test utility in the Windows SDK for ia64, "C:Program FilesMicrosoft SDKBinWin64ia64odbcte32.exe". If you connect to the SQL Server driver and then simply call SQLGetStmtAttr(SQL_ATTR_CONCURRENCY), you'll see that the *StringLengthPtr argument returns 8 bytes, when it should only return 4.
Note that we've also seen the same behavior with SQL_ATTR_ROW_BIND_TYPE as well as other statement attributes defined to return SQLUINTEGER values.
Has anyone else run into this?
Thanks,
Chris

I have a SQL express database which I need to access from a shared hosting plan. I can create an ODBC connection through the hosting provider's control panel for SQL Server, but it won't connect. I tested this locally and discovered that the SQL Native Client connects fine, but the previous SQL Server driver does not. This seems to only happen with SQL 2005 Express edition; it works with the Developer Edition. Does SQL Express only use the Native SQL Client??
Thanks in advance for your help!

VWD 2005 Express. Visual Basic. Sql Server 2005. I am trying to establish a connection to a SQL database. The connection (and all other database reads and writes) work fine in debug and in "view in browser" from VWD. I am running the VWD on the same server that hosts the site. When on my server (Windows 2003 Server) under IIS, the connection attempt times out.
Below is the code that is failing (only on the server when deployed):
Private Shared Sub OpenConn(ByVal cmd As SqlCommand, ByVal Success As Boolean)
Dim conn As New SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings("GoodNews_IntranetConnectionString").ToString)
'The connection string resolves to ("Data Source=HQSERVERHQSERVER;Initial Catalog=GoodNews_Intranet;Integrated Security=True"
Try
conn.Open()
cmd.Connection = conn
Success = TrueCatch ex As Exception
Success = False

As stated in the subject I have a situation where if database mirroring is employed for either manual or automatic failover, all the client (including web connections) connections use ODBC not ADO, or OLEDB etc... so what methods are recommended? Client side redirect is not available so I could not employe the "Data Source =A; Failover Partner=B..." option.
Right now the method employed (pre database mirroring and basically employing log shipping on SQL 2000) is to have a DNS alias for the ODBC connection so that if the server were to change in a failover situation the DNS record would have to be altered, so that all the client connections would not have to be reconfigured.

Dominic Baines

SQL Native Client 2005.90.3042.00 ODBC driver does not return SQL_CVT_DOUBLE as part of the mask from SQLGetInfo for SQL_CONVERT_WCHAR, SQL_CONVERT_WVARCHAR even though driver actually supports converting nchar and nvarchar to SQL_DOUBLE. For example,
select
{ fn convert(N'1.23', SQL_DOUBLE) }
works, but
SQLUSMALLINT nInfoType = SQL_CONVERT_WCHAR;
SQLUINTEGER nInfoValue = 0;
SQLRETURN rc = SQLGetInfo( hdbc, nInfoType, &nInfoValue, sizeof( nInfoValue ), NULL );

Hi,
When I'm using SQL server 2005, and ODBC drive €œSQL Native Client€? I get an error when executing the below given code. Error Message: €œTransaction cannot start because more than one ODBC connection is in use.€?
But this works well with SQL Server 2000 with ODBC drive "SQL Native Client" and in SQL server 2005 also when I used ODBC drive €œSQL Server€?.
I used aTrgConn.Execute(€œBegin Transaction€?) and it's working properly. But unfortunately I cannot use this method, because I want to run the same code with Oracle ODBC as well.
Is this a known issue in SQL Native client drive with SQL server 2005? Do you know a solution for this?
Please Help..............
Thanks in advance.
Code:
Dim aTrgConn As New ADODB.connection
Dim aCmdIns As New ADODB.Command
Dim aCmdUpd As New ADODB.Command
aTrgConn.Open sConnStr
Set aCmdIns.ActiveConnection = aTrgConn
Set aCmdUpd.ActiveConnection = aTrgConn
aTrgConn.BeginTrans

Hi folks,
I have installed SQL Server 2005 on my Domain Controller successfully
and installed the SQL Server tools from the DVD including workstation components on my XP client computer (which is actually hosting the Domain controller as virtual VMWare machine).
The authentication is set to mixed mode and I have created a login with all possible rights on SQL Server, but which is at the same time my Domain Admin (So the user is setup in SQL Server in the format Domainuser)
Now when I open any client program (SQL Srvr2005 Management console, or Toad for SQLSrvr) and try to connect, the client does find the server correctly, but I cannot login.
The error status is actually 1, which means "unexpected internal error" as far as I have read.
I have turned off Windows firwalls by default and also turned off my custom firewall to see if it makes a difference, but it doesn't.
My activated connection protocol on both the server and the client is TCP/IP and I have then changed the port on both the server and the client to a common 4665, which I then granted full passage through my firewall.
Now the error has changed and says "the target machine has actively refused the connection", with status code 0... ???
So that's my current situation... Please, can anyone help me? What am I doing wrong?
Any tips would be appreciated,
-Patrick-
