Problems Opening SQL Server 2000 Connection From Website
Feb 15, 2007
I am getting the error message below when trying to connect to SQL Server 2000. Here are the details:
Problem is occuring with a new website trying to connect to SQL Server. The error occurs right at the open statement.
Using SQL Server 2000
Web server is on a different machine than SQL Server
I have many websites connecting to this SQL Server. Websites are all on the same webserver.
I can connect to this SQL Server using the Query Analyzer using the same ID and PW as in my connection string
My web application runs OK using this SQL Server when I run it from my laptop - just changed the connection string Initial Catalog parameter.
Any help would be appreciated.

I'm developing an intranet site in ASP.NET 2.0 but I can't seem to connect to the DB from within my code. I've created a .vb class that houses a private Connection() that other functions within the class can call to connect to the database. In the calling function, I've declared my connection object and called the "Open" method on the object. However, when I attempt to execute the stored procedure command by calling the "ExecuteScalar" method, I get the following error:
"ExecuteScalar requires an open and available Connection. The connection's current state is closed."
Here's the code from my class:
Imports System.Data
Imports System.Data.SqlClient
Namespace Encompass
Public Class EncompassSecurity
Public Shared Function GetHRIDByNTUserID(ByVal strNTUserID) As String
Dim strHRID As String
'Create command object
Dim cmd As New SqlCommand("usp_Get_HRID_By_NTUserID", Connection())
cmd.CommandType = CommandType.StoredProcedure
'Open DB connection
Dim DBConnection As SqlConnection = Connection()
DBConnection.Open()
'Input parameters
Dim inNTUserParam As New SqlParameter("@NT_UserID", SqlDbType.VarChar)
inNTUserParam.Direction = ParameterDirection.Input
inNTUserParam.Value = strNTUserID
cmd.Parameters.Add(inNTUserParam)
'Output parameters
Dim outHRIDParam As New SqlParameter("@HRID", SqlDbType.Int)
outHRIDParam.Direction = ParameterDirection.Output
cmd.Parameters.Add(outHRIDParam)
'Run stored procedure
strHRID = cmd.ExecuteScalar()
Return (strHRID)
'Close DB connection
DBConnection.Close()
End Function
Private Shared Function Connection() As SqlConnection
Dim strConnectionString As String
strConnectionString = ConfigurationManager.ConnectionStrings("Conn").ConnectionString
Return New SqlConnection(strConnectionString)
End Function
End Class
End Namespace
Here's the code from my web.config file:

Well here is my connection string, I used these details to succesfully access the server from mySQL gui.
SqlConnection shhfd = new SqlConnection ("Data Source=http://www.mydomain.co.uk; " +
"user id=mteccles; password=mypass; connection timeout=30; "
then... try { shhfd.Open(); blah blah blah.
The exception caught is as follows.
at System.Data.SqlClient.ConnectionPool.GetConnection(Boolean& isInTransaction) at System.Data.SqlClient.SqlConnectionPoolManager.GetPooledConnection(SqlConnectionString options, Boolean& isInTransaction) at System.Data.SqlClient.SqlConnection.Open() at WebService1.Service1.HelloWorld() in g:inetpubwwwrootwebservice1service1.asmx.cs:line 120
My guess is that something in the web.config isn't right or maybe the host (webfusion) is strange. Thanks if anyone can help.

Hi,
I have a application running on Biztalk server , VS 2008 and SQL server 2008.
I have opened a SQL connection string and referring some DB which works absoluetly fine.
But in my code in C#, i try to open another connection with some different database, as i apply the connection.open(), it gives me a very strange error of Sql server 2005. And i dont have Sql 2005 on my box.
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) (Microsoft SQL Server, Error: 53)
Can you please help me out??
Thanks.

Where can I further educate myself on this subject?
Right off from the start I would assume that installing SQL Server 2000 or 2005 on Windows Server 2003 that is set up as a web server hosting a website would be against "best practices." Is my assumption right?
Common sense tells me to not to host a website on a pc that is also hosting my database.

Hi
I access a DB by as abvious creating a DB Connection and then sending a querry to it. Finally creating an SQL Command and then exuting it.
But the thng is I am using a static function:
which opens a new connection and returns a data reader based on the querry. i.e
pubblic static SqlConnection OpenConnection()
{
try
{
string connectionString = "Data Source=mm\SQLEXPRESS;Initial Catalog=monsoonDB;Integrated Security=True";
SqlConnection conn = new SqlConnection(connectionString);
conn.Open();
return conn;
}
catch (Exception ex)
{
throw;
}
}
Now I have the execute selectquerry function.....
public static SqlDataReader ExecuteSelectQuerry(string querry)
{
try
{
SqlConnection conn = OpenConnection();
SqlCommand scomm = new SqlCommand(querry, conn);
SqlDataReader sdr = scomm.ExecuteReader();
return sdr;
}
catch (Exception e)
{
return null;
}
}}
now my question is....the instance of conn is limited only to that function only, and not returned outside. Whereas only the SqlDataReader is returned outside. Does that have any abnormal affect on the application. Since my ASP Application is getting locked (not doing anything, nt even post back!) sometimes after a few DB operation.
Arent these connections and instances Managed (auto garabage collection)?? Can memory leaks under such a situation occur.
Please help
Thanks

Hi most of my code follows the following format in a lot of my pages, my question is; Am i approaching it the right way in terms of performance, sql injection attacks and anything someone more knowledgeable than myself can think off, please feel free to criticise the code. Thank youprotected void Page_Load(object sender, EventArgs e)
{string strID = Request.QueryString["id"];
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["streamConnectionString"].ConnectionString);SqlCommand command = new SqlCommand("stream_EventsByID", conn);
command.CommandType = CommandType.StoredProcedure;command.Parameters.Add("@eventID", SqlDbType.Int).Value = Request.QueryString["id"];
conn.Open();
SqlDataReader reader = command.ExecuteReader(CommandBehavior.CloseConnection);
eventList.DataSource = reader;
eventList.DataBind();

Hello, Im new with databases.
I know that opening a connection to a DB is expensive. Usually I write a method that opens a connection to the DB then I execute a query and then close the connection. Pretty standard.
OK, so how do I handle opening connections to the database when I need to run multiple queries. For example, i have a webpage that need to query the database to see if the user has moderator privledges, then depending on that query I have to query the DB again for moderator specific information or non-modertaor information.
So in this case how do i handle opening connections to the DB. Is it ok to generally have to open a connection to a DB multiple times on a page load?
The obvious solution is to keep the connection open. That is, open a connection, query the Db, keep the connection open, do the conditional statment ( if is_Moderator) then query the DB again for the info that I need, and then close the connection. But, from all the books that Ive been reading this is not a good practice because business logic should not been in the dataAccess layer.
Any help would be much appreciated.

I have had a local Website up and running based on the MS Personal Website Starter Kit using Visual Studio 2005 Professional and SQL Server Express.
I am now trying to get the databases to run on SQL Server 2005 Standard Edition but can't get the connection to work.
I have changed the connection string in the Web.Config file from:
connectionString="Data Source=.SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|Personal.mdf" providerName="System.Data.SqlClient"
To
connectionString="Data Source=.scastle;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|Personal.mdf" providerName="System.Data.SqlClient"
But am getting the following error:

Line 9: End If
I am able to connect OK in both Server Management Studio (Server Name: SCastle, Windons Authentication) and clicking Connect to Database in Server Manager in Visual Studio (Server Name: (local)).
Have I got the connection string wrong or do I need to set up additional permissions in the database?
Thanks for your help.

Hi all,
I've got a little problem.
I'm working on a ASP.NET project. The applications has 4-layers. When I look in the Data Access Layer and test the typed dataset, then the "Preview Data" works fine. I see the right records from SQL Server 2005.
But when I run the app (default.aspx) in debug-mode, then the system gives the following error:
"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)"

(Hope this isn't a "stupid" question, but I haven't been able to find a straight-forward answer anywhere)"
I currently have code that iterates through a dataview's records, making a change to a field in some of the records. The way I have this coded, a conection has to opened & closed for each individual record that's updated:
dsrcUserIae.UpdateCommand = "UPDATE UserIAE SET blnCorrect = @blnCorrect WHERE (ID = @ID)" dsrcUserIae.UpdateParameters.Add("blnCorrect", SqlDbType.Bit) dsrcUserIae.UpdateParameters.Add("ID", SqlDbType.Int)
Dim myDataView As DataView = CType(dsrcUserIae.Select(DataSourceSelectArguments.Empty), DataView) For Each myRow As DataRowView In myDataView If myRow("FkUsersAnswerID") = myRow("AnswerID") Then intCorrect = 1 Else intCorrect = 0 End If dsrcUserIae.UpdateParameters.Item("blnCorrect").DefaultValue = intCorrect dsrcUserIae.UpdateParameters.Item("ID").DefaultValue = myRow("ID") intUpdateResult = dsrcUserIae.Update() Next
It seems like I should be able to do something like this (call update once), but I'm not sure how...
dsrcUserIae.UpdateCommand = "UPDATE UserIAE SET blnCorrect = @blnCorrect WHERE (ID = @ID)" dsrcUserIae.UpdateParameters.Add("blnCorrect", SqlDbType.Bit) dsrcUserIae.UpdateParameters.Add("ID", SqlDbType.Int)
Dim myDataView As DataView = CType(dsrcUserIae.Select(DataSourceSelectArguments.Empty), DataView) For Each myRow As DataRowView In myDataView If myRow("FkUsersAnswerID") = myRow("AnswerID") Then myRow("blnCorrect") = 1 Else myRow("blnCorrect") = False End If Next
intUpdateResult = dsrcUserIae.Update() 'Want all changed myRow("blnCorrect") to be updated to datasource
Can anybody explain how to do the bulk update? I've seen some info about AcceptChanges and Merge, but I'm not sure if they apply here, or if they more for Transactions.

Hi,
I'm writing an application with Visual Studio 2005 (Visual Basic .NET 2.0) which uses a SQL Compact Edition 3.5 database. On my HTC Touch with Windows Mobile 6.1 installed the application crashes, without any error message, if I try to open a connection. But...On the Windows Mobile 6 Pro emulator the connection opens normaly. The whole application runs perfect.
On both "devices" are the same dll's, of version 3.5.0.0.
I'm using the following code to open the connection:
Code Snippet
Private mySQLce_strConnection As String = "Data Source ='" & App_Path() & "MControl_SQLce.sdf" & "';"
Dim localConnection As New SqlCeConnection(mySQLce_strConnection)
localConnection.Open()
I tried so many things but without any success. But...I'm able to open the database (MControl_SQLce.sdf) with the Query Analyzer 3.5 on the Mobile. No problem.
This is my configuration:
Dev PC:
Windows XP SP2
Visual Studio 2005 Pro
.NET Framework 2.0 SP1
.NET Compact Framework 2.0
SQL Server Compact Edition 3.5 (this version I reference to in my VS project)
Mobile Device (HTC Touch):
Windows Mobile 6.1
SQL Server Compact Edition 3.5
Any suggestions? I can't figure this out.

Hello everyone. I'm very new to asp.net. I've been coding in vb.net for a while now (getting my associates degree in desktop application programming) and my boss wants all of my new applications to be web based now. Well, i decided to take some initiative on this and begin a new project for my department. This is a very small project. So far, everything is coming along alright (i found an eBook that's helped me quite a bit). Everything was cool until yesterday when i tried to connect to our sql server database. I get an error message stating:

Because i'm testing this on my system as well as the remote system which hosts the application, i can see the error message on the remote system. Here is the error it's giving me:

You can see my SQL Connection string in there as well. Can someone please help me with this? I can post the code to the entire page as well if that would help. I'm developing this with Dreamweaver MX 2004 (i like dreamweaver MUCH better than visual studio, especially for web design/development). Thanks,
Eric

I'm pretty sure this problem started after applying Windows 2000 SP2 on machines running SQL 7 SP3. It may be that I only started manipulating these particular DTS jobs since that upgrade.
Problem: In EM I open a DTS package and it causes the server machine to crash to a blue screen. This has happened from a Windows 98 workstation running against a Windows 2000 Server SP2 running SQL7 SP3 and on a standalone laptop running Windows 2000 SP2 running SQL7 desktop edition SP3
Can anyone point me to more information on why this is happening?
Thanks
Doug

Hi,
I'm trying to connect to an SQL server 2000 database table from my PDA using VB.NET through a bluetooth connection. I keep getting an error telling me that I cannot connect. I have tried everything that I can think of to fix it.
Do I need a copy of SQL Server CE on the PDA, even though I'm only viewing data from my PC's database on my PDA?

Can I connect from a SQL Server 2005 database to a SQL Server 2000 database, without establishing a linked server connection.
I need to fire a SELECT query on a SQL Server 2000 database, but don't want to add it as a linked server. Is there any way I can do this or its not possible??

I am trying to make a simple connection to my sql server, but am getting an error. I am not sure why it says SQL Server 2005 in the error as we use 2000. I have found others to have the problem on the web, but have found no answers. One person said the sql connection worked when he downgraded to 1.1; however, I'd like to avoid that. Here is my code:
<%@Import Namespace="System.Data.SqlClient" %>
<script runat="server">
Sub Page_Load()
Dim conNorthwind As SqlConnection
conNorthwind = New SqlConnection("Server=1CDRSRV4; uid=username; pwd=password; database=Northwind")
conNorthwind.Open()
End Sub
</script>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
Connection Opened!
</body>
</html>
here is my error:

i'm using sql server 2005 express edition as the database server for my web application. Right now, i want to deploy it and the problem is, my hosting is using sql server 2000. So, is it possible to deploy my database that has been created in sql server 2005 in the sql server 2000? I'm afraid that the connection string for sql server 2000 is different from sql server 2005. In addition, i'm using forms authentication in my web application. So, some data regarding to the forms authentication like dbo.asp_net.membership table, dbo.asp_net.roles table is in my database. Is it the table that has been created like dbo.asp_net.membership can be used in sql server 2000 since it is created by asp.net forms authentication function?

Hi all,
I am trying to trouble shoot this database VS 2003 web application I have. I cannot connect to the database on the server through the VS program. However, I can connect to the server database via Enterprise Manager on my machine. Also, I am able to connect my VS 2003 program to a replicated database on my local machine, it connects without a problem. So, I am assuming there is a setting that is not right on the server machine. I am running SQL Server 2000. But, I am getting this error below which seems to apply more to Server 2003.
Any ideas?
Thanks!

I have asp code that uses C# to create a SQL connection and a command. Then I create a data set and fill the data set using my comand. Finally I bind my data set to a data grid named myDataGrid. I am not sure where myDataGrid comes from since it is never defined. Where does myDataGrid come from? Also, I believe that I do not need to call page_Load since auto wire is set to true by default so it is my understanding that this method page_Load will be called by default.void page_load(object sender, EventArgs e) { SqlConnection myConnection = new SqlConnection("server='(local)'; trusted_connection=true; database='mattsDEMO'"); SqlDataAdapter myCommand = new SqlDataAdapter("select * from people", myConnection); DataSet ds = new DataSet(); myCommand.Fill(ds, "people"); MyDataGrid.DataSource=ds.Tables["people"].DefaultView; MyDataGrid.DataBind(); }
When I place a data grid controll on my page named myDataGrid, I do not see a data grid and there is no data either. The code in the HTML looks like this:
<body> <form runat="server"> <p> <asp:DataGrid id="myDataGrid" runat="server" BorderColor="Maroon"></asp:DataGrid> </p> </form></body>I tried using debug that comes with the .Net framework (since I am using Web Matrix) but I get an error saying no symbols were found for this document when setting break points. What are symbols and why do I need them?So, I basically have four (4) important questions that I need help answering: 1) Why do I not have any data in my data grid? 2) Where did myDataGrid come from? 3) Is the page_Load method called by default if auto wire is set to true or not declared? 4) Why do I need symbols for debug?Below is all my code in one complete view:<%@ Page Language="C#" %><%@ Register TagPrefix="wmx" Namespace="Microsoft.Matrix.Framework.Web.UI" Assembly="Microsoft.Matrix.Framework, Version=0.6.0.0, Culture=neutral, PublicKeyToken=6f763c9966660626" %><%@ import Namespace="System.Data" %><%@ import Namespace="System.Data.SqlClient" %><script runat="server">
// Insert page code here //
</script><html><head> <script language="C#">void page_load(object sender, EventArgs e){SqlConnection myConnection = new SqlConnection("server='(local)'; trusted_connection=true; database='mattsDEMO'");SqlDataAdapter myCommand = new SqlDataAdapter("select * from people", myConnection);
DataSet ds = new DataSet();myCommand.Fill(ds, "people");
MyDataGrid.DataSource=ds.Tables["people"].DefaultView;MyDataGrid.DataBind();}
</script></head><body> <form runat="server"> <p> </p> <p> <asp:Label id="Label1" runat="server">This is a test!</asp:Label> </p> <p> <asp:DataGrid id="myDataGrid" runat="server" BorderColor="Maroon"></asp:DataGrid> </p> </form></body></html>Thanks,Ryan

I am using asp.net 2.0, and am attempting to connect to a SQL Server 2000 database. When I run the web page either in the debugger, or by viewing it in the browser, I get the following error message:
Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server connection.
I think that maybe my values for uid, and pwd are not correct? If this is the problem, then I don’t know what their values should be? Should uid always be equal to sa ??(If so why?)
Also I don’t know what the password should be. I don’t know what the name of the password as it was assigned over two years ago when I installed sql server 2000. I might need some instructions on how to find this value in SQL server.
Someone please help me if you can. Here is a snippet of the code I am using:
String sqlStmt = "INSERT INTO LogIn (UserName,PassWord) VALUES ('JohnyRocket','FastestRocket99')";
SqlConnection sqlConn = new SqlConnection("server=localhost;uid=sa;pwd=;database=MyWebSite;");
SqlCommand sqlCmd = new SqlCommand(sqlStmt, sqlConn);
sqlConn.Open();
