* Strange SQL Server Connection Error *
Oct 10, 2005
Hi guys,
We've been experiencing this strange error from our SQL server for about a month now and i've tried alot of things, visited alot of websites and manufactured a few possible solutions but nothing helps! Its very frustrating.
This is the error i get when i try and expand the server tree:
A connection could not be established to [OurServerName]
Reason: SQL Server does not exist or access denied.
ConnectionOpen (Connect())..
Please verify SQL Server is running and check your SQL Server registration properties by clicking on [OurServerName] node) and try again.
What really gets to me is that everything works after i restart the server. Then things will go fine for about a day or two and then the same thing again. This i causing alot of downtime for us. Can anyone please just give me a suggestion? :confused:

Hi,I need some help. I am getting this error after I complete the asp.net register control and click on the continue button. It crashed when it tries to get it calls this Profile property((string)(this.GetPropertyValue("Address1")));When I look at the stack, it is coming from my ProfileWrapper class which adds user address, city, etc.. from a class which inherits fromSystem.Web.Profile.ProfileBase. From the stack, it is calling the System.Web.Profile and crashed when it tries to open a connection atSystem.Data.ProviderBase.DbConnectionPool.GetConnection(DbConnection owningObject). I already migrated all aspnet_user, aspnet_roles, etc.. and don't get any connection errors. It is only when I try to get the profile data. This works on my pc, but throws an error on my lunarpage website.Any help is greatly appreciated.Thanks,AJAn error has occurred while establishing a connection to the server.

I get this SQL-sever error in my application. I guess it has something to do with the declaration of namespaces? Does anyone know for sure? Thanks in advance!

I have a script that creates a database and sets up everything required for merge replication. Merge replication is pull with a single parameterized row filter based on HOST_NAME() and joins on other tables. It works perfectly.
I recently decided to drop all my identity columns and use rowguid's instead.
I modified my script by only changing the primary key column definitions, basicaly I went from "[Id] [int] NOT FOR REPLICATION IDENTITY (1,1) NOT NULL PRIMARY KEY CLUSTERED" to "[Id] [uniqueidentifier] ROWGUIDCOL NOT NULL DEFAULT NEWSEQUENTIALID() PRIMARY KEY CLUSTERED".
The script still works fine. Everything is executed succesfully and even the snapshot agent finishes it's job.
But the problem is, that when I want to create a partition I get the following error:
A value for the parameter @host_name was specified, but no articles in the publication use HOST_NAME() for parameterized filtering. (.Net SqlClient Data Provider). Microsoft Sql Server, Error: 20672
If I try to synchronize a subscription then the subscription is created succesfully, but I get an error while synchronizing stating:
Merge agent was unable to determine if another subscription exists for the current partition.
And yes, I do have my filters set up 100% correctly.
The funny thing is, if I create the publication via Management Studio, then I don't get that error.
But if I create the publication via Management Studio, immediately afterwards generate the script for it, delete the publication and create the publication from the generated script, I get the error again
From this I have concluded that no way can the problem be in my new script...
Everything is dandy fine with the server as well, because the original scipt still works flawleslly.
Does anyone have any ideas what I could try to get things working?
Has anyone even gotten merge replication set up via script, while database -> uses only rowguids, hostname parameterized filter and joins?
Or should I just report this as a bug to Microsoft and go back to my original script, including the identity hell?
PS! I'm using Windows Server 2003 Standard x86 SP2, SQL Server 2005 Standard x86 SP2

Can anyone help me solve why my server is locking up.
We're running sql server 2005 ent on a 2 cpu dual core server. With 3gig. Once each the last couple weeks, the machine has hung and the only thing I can find that's suspicious is on the sql server log. It's below. After the excerpt is about 50 more different memory errors. As far as I know there's no ssl configured for log in, it mostly uses private lan cards for security between it and the web/application server.

Hi All,
we are working on a web application created in ASP & SQL 2000 environment.
In the code , we have a single connectionstring to connect database.
The application was running fine for the past 3 years, but all of a sudden we are getting "timeout expired" error only in someparts of the application but not on all database access.
The code which raises this error is a bit large which need to look into table of 8k recs with more conditions.
The same sql query took 1:01 minutes to execute in query qnqlyser.
I changes the script timeout to 900secs,
I herd we need to upgrade MDAC or we need to change connection timeout or we need to cahnge the code.
we cannot change the query, it is the most possible way we could get that.
Can somebody help me with the possible solution.
Thanks & Regards,
Sai. K.K

Hi,We have 2 servers. Server1 is a 2000 box, with SP3 (yes I know it isnot up to date). Server2 is a 2005 box, SP2.I set up Server1 (2000) to have a linked server to Server2 (2005). Thereason I did this is because we are using a stored procedure onServer2 to send mail, as we have found that using mail on 2000 doesn'talways work as advertised.When I set up the linked server on the 2000 box, for security I justset it up to use a SQL Server user on the 2005 box. The SQL Serveruser on the 2005 box has permissions to run the stored procedure forsending mail.Here's the weird thing though. When calling the stored procedure onthe 2005 box from the 2000 box, sometimes we get an error that "Thedefault database cannot be opened", and the query does not run on the2005 box. However, it only happens *sometimes*. Other times, the queryruns fine.Since the problem seeemed to be with the default database, I changedthe SQL Server user on 2005 default database to the SAME database thatcontains the stored procedure.However, I just don't understand why it's even TRYING to open thedefault database, since when we called the linked server we are doingso as, and it's referencing the default database in the name:EXEC Server2.DefaultDatabase.dbo.StoredProcedureNameHowever, after changing the user's default database to"DefaultDatabase" as shown above, the query runs fine.Why are we having this problem? That is, if I change the defaultdatabase to something other than "DefaultDatabase", then the querydoesn't run, even though the database name is referenced in the abovequery??Obviously, this is not desireable, because that means we can only runqueries that are in "DefaultDatabase", which may not always be thecase.Thanks much

I am sure I am using the same connection string for all connection.open, and closing all connections as soon as possible… but
When I try to debug my web app with vs, it runs for some time then I get:
The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached exception
However, if I just access the application normally form the url (not using vs.net) it runs flawlessly.
Has some one had the same problem? i can't debug help!!

Vendor app (written in VB '05) connects fine building screens that list data from only one record but blows up building 'list' screens that list multiple records. Really strange-it works fine when run locally on the server (Win2K3) and when run from one developer's machine (which has VS 2005 but not SQLExpress) but not from other developer's machines (which have both VS 2005 & SQLExpress) nor from a 'user' machine (which has neither). All have .Net Frameworks 2.0, the developer machines have SQL Management Studio & connect fine via that.
Vendor, of course, says it's a configuration issue so not their problem. I'm trying to figure out what they could be doing differently when building a list screen & therefore why it would fail. Fact that it works locally suggests that the failure is in the remote connection-but fact that it connects on 'single record' screens says that remote connections work. So what would be different about a request to return multiple records and why would it work locally but not remotely?
BTW, Surface Area Configuration Manager won't run-it reports 'localhost does not exist on the network or it cannot be configured remotely'. This is when running the Configuration tool directly on the server.
Any ideas?

Hi
I've got a database in SQL Server 2000 on Windows Server 2003 which appears to be okay from SQL Enterprise Manager and from SQL Query Analyser but which has a problem with one particular table when connected to from a VB DLL using ADO. The queries do either a select or an insert - the latter is via a stored procedure. Once the failure happens, any other queries generate a -2147217871[Microsoft][ODBC SQL Server Driver]Timeout expired.
If I delete the table and recreate it all is well. If I run an integrity check nothing shows up. I've tried deleting the indexes and that made no difference either. SQL Server is patched up to SP4 and ADO is from the MDAC 2.8. VB is version 6 Enterprise with SP6. None of the other databases in the instance exhibit the problem and they're all structured in an identical way. The table is quite large but we've got much larger one's using the same procedures and they don't have a problem. Also, if I restore a backup of the problem database onto another machine the problem shows on the other machine too.
Any ideas anyone?

Hello,I developed a win32 .exe CGI that connects to a clustered SQLServer toreport some data.The software is written with Borland C++Builder.This is the oledb string:Name=Provider=SQLOLEDB;Password=xxx;Persist Security Info=True;UserID=xxxx;Data Source=xxxxx;Initial Catalog=xxxxx;NetworkLibrary=dbmssocnIt suddendly stopped working on my customer network, so I made sometest and I verivied that the problem is on the connection withSQLServer: my test program just opens a connection, closes it andexits, reporting in a log file if the open was successful or failed.If I run the program locally, just launching it, no problem, it works.I can run it mutilple time continuosly and is connects every time.If I run the program through my webserver, as a CGI that's how it issupposed to work (http:\localhostscriptsconnect.exe), it connectsthe first time, and then I have to wait 40 seconds to connect againsuccessfully, or it fails.If I try against MY sqlserver on my laptop or on my network no 40 secproblems, but on my customer network, with THEIR SQLServer , if I tryto connect from their webserver, or from my laptop webserver, I havethis 40sec problem.I analyzed the network traffic, and I discovered that when I run mytest program locally it originates only TCP/IP packets, and SQLServeranswers only with TCP/IP.But when I use it from the webserver as a CGI, it originates an UDPpacket, then SQL answers with another UDP packet, and then theycommunicate over TCP/IP.This when it works: the second time my program continues to send theUDP packet, but it receives no answer, and fails the communication.I can only say that:- we haven't touched the program for months, and it really stoppedworking suddendly, so I suspect that something in my customer netowrkhas changed- I tried many different OLEDB strings, disabling connection poolingand all the services, calling the SQLServer by name or IP...- the problem can't be related to my program, because now is reallyjust an oledb connection testAnyone have an idea?Thank you very much,Mattia

Well this has got most of us stracthing our head as not matter what we do we can't connect remotely
But it get's a bit more complex. We have an existing web application running with a local instance of express running fine. However as the server is getting hammered we need to put the new version of the site on a second server. Unfortunately the key contact who use to work on the old system and set it up is no longer avialable. We've been through all the basics and nothing works... our latest attempt was to install a new instance of 2005 as we were not sure what was going on.
So, here is the log for this new clean instance:

How do I know this is not a connectivity/firewall issue? Simple:
1. We stop the SQLExpress instance
2. Setup netcat to listen on that port (nc -l -p 4286)
3. Connect via telnet (telnet SERVERNAME 4286) and type something which then appears printed out on the other end.
Anyway, the Windows Firewall is off and I can't see any other firewalls installed (we did not setup this server).
Btw, if we try and connect to the existing instance we get:

Hi, I had an old web application created during asp.net 1.1 and it have a connection problem with the sql server 2005 when it is mirgrated to a new webserver with dotnet framework 2.0 platform. I have enabled the remote access(TCP/IP and named pipes) in sql server 2005, did all the neccessary things, check whether the TCP/IP is enabled, named pipe is enabled... I created another web application using VS 2005. The database connection works perfectly well.This are the connectionString from the old web application.<appSettings> <add key="ConnectionString" value="Server=127.0.0.1;Database=somedb;User id=user; Password=somepassword; Trusted_Connection=False; POOLING=FALSE"/></appSettings> Thankyou in advance!

I have a Rounding error: Between flat file connection manager Source & OLE DB Connection Destination (SQL Server 2005) in my Dataflow.
File looks like this lets call column names Col A,B,C,D

I have a field of text of in a flat file that the flat file connection manager Source picks up correctly €ś70000893€?
However when it gets the OLE DB Connection Destination the data has changed to 70000896. That€™s before its even Written to the database.
The only clue that something is wrong in the middle is the great Data viewer shows the number as 7.000009E+07
Other clues looking at the data it appears there is a rounding error on only the number that dont end in 00

Now you all must admit that, if your somewhat new to this databasing, It's a ***.
The source for my application is Visual Web Designer 2005 Express
It is an ASP.Net driven site with membership roles and all the good stuff.
the latest theory is that I need to change the provider config in the web.config file from AspNetSqlProvider
to something else. Most of my complications and frustrations come from GoDaddy and no access to the
shared server (understandibly).
I hope I gave enough info for help and not too much..

I am using c# and ASP.NET 2 and I am getting a very strange error. I
have a field called CompanyID in SQL Server 2005, and it allows null
values in it. When this CompanyID is not NULL, ie for example it is
202, then when i press the update button it allows me to update
perfectly in the database. However if the CompanyID is NULL,
and I try to update the companyID, to lets say 202, the application
just crashes with the following message:- System.InvalidCastException: Object cannot be cast from DBNull to other types. I tried to set some breakpoints in the application to debug, however it does not even pass through these breakpoints! Any ideas on what the problem can be or how I can debug? Thanks for your help and time Johann

Hi,
In my package I am executing 8 'Execute package' tasks which calls 8 different packages. All these tasks are indepent so they are not connected to each other. In each package I have defined a variable at the start of each package there is a script task to assign the 'StartTime' system variable value to the user defined variable.
If I run the tasks individually, it is running without any problem. When I am running all the tasks in the parent package, very often the package fails and each time different different tasks are failing. But the error happens at the script task which is used to define the start time. The error message is 'Error: The script threw an exception: Object reference not set to an instance of an object.'. But inside the script task, I have only one statement which assigns the system start time value to the user variable. Also, in my log file, I am getting 2 entries for all the tasks in that failing child package, but I have not specified any looping in my parent package. One more peculiar thing is even though as per the log entry it ran twice, no single record is inserted/updated(????).
Anybody have any idea of this problem?
Thanks.

Hello,
I am running the code below that simply adds a row with two values to a Table. When it is run, it gives me the following error:
A .NET Framework error occurred during execution of user defined routine or aggregate 'InsertCurrency':
System.Data.SqlClient.SqlException: Violation of PRIMARY KEY constraint 'PK_Sales.Currency'. Cannot insert duplicate key in object 'dbo.SalesCurrency'.
This seems to indicate I am adding a duplicate key, however I have confirmed several times that I am not adding a duplicate key.
Here is the code. Thanks for any suggestions about why this error is occuring.
<SqlProcedure()> _
Public Shared Sub InsertCurrency(ByVal currencyCode As SqlString, ByVal name As SqlString)
Using conn As New SqlConnection("context connection=true")
Dim InsertCurrencyCommand As New SqlCommand()
Dim currencyCodeParam As New SqlParameter("@CurrencyCode", SqlDbType.NVarChar)
Dim nameParam As New SqlParameter("@Name", SqlDbType.NVarChar)
currencyCodeParam.Value = currencyCode
nameParam.Value = name
InsertCurrencyCommand.Parameters.Add(currencyCodeParam)
InsertCurrencyCommand.Parameters.Add(nameParam)
InsertCurrencyCommand.CommandText = _
"INSERT SalesCurrency (CurrencyCode, Name) VALUES(@CurrencyCode, @Name)"
InsertCurrencyCommand.Connection = conn
'
conn.Open()
InsertCurrencyCommand.ExecuteNonQuery()
conn.Close()
End Using
End Sub

I have a table called subscribers with the following fields
CustID (identity)email (text) fname (text)lname (text) - may be emptysubDate (smalldate)Confirmed (boolean) - initially will be emptyConDate (smalldate) - initially will be empty
I have a strongly typed dataset that contains only the one table. It has the method GetDataByIsSubscribed
SELECT emailFROM SubscribersWHERE (email = @email)
And I have a function which calls it
Public Function ValSubscribe(ByVal vEmailAddr As String, ByVal vFName As String, ByVal vLName As String) As String Dim SubscriptionAdapter As New EmailSubscriptionsTableAdapters.SubscribersTableAdapter Dim dF As Data.DataTable = SubscriptionAdapter.GetDataByIsSubscribed(vEmailAddr) If dF.Rows.Count > 0 Then ValSubscribe = "This email address is already subscribed!" Else SubscriptionAdapter.InsertSubscriber(vEmailAddr, vFName, vLName, Now) ValSubscribe = "success" End IfEnd Function
This is an existing table that contains duplicate email addresses, but I don't want to add any more dups.
You can see I have another method to add records, which works fine, though I've only tried to add email addresses that I know aren't in the table. If I run the above code which first checks to see if an email address is in the table, and I use an email address that is, I get the following error
System.Data.ConstraintException was unhandled by user code Message="Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints."

I think I understand what this error is telling my, but I don't get why. All the fields except CustID allow nulls. There are no foreign-keys, and I don't see where any fild by custID requires unique entries. If I run the query in the designer, I don't have a problem.
What am I missing?

I have a function that retrieves a data set from a passed SQL string. I'm getting this weird error.
Input string was not in a correct format

I have no idea why, but it seems to trying to convert the string into an integer. Both the argument and the parameter in the function are strings. I checked on the internet and the usual response is this is because the SQL is incomplete, but I have it showing me the compiled SQL string, and it is not imcomplete. I've tried hotwiring the query to match something I know will work, and I still get the same error. I've also tried compile the string using .ToString() on my number portion, storing the converted number into a string and only combining strings on the call, using another string variable as a temporary holder, using the String.Concat function, and even CStr. There is no way possible that this thing is an integer when the call is sent...
Any ideas?
