Cannot Create ADO Connection To DB Anymore...
Jul 20, 2005
I rebuilt my machine a few weeks back - re-installed the developer version...
The app in question can see all it's tables in the SQL back end via ODBC and
everything looks normal via Enterprise Manager, but I can no longer create
an ADO Connection.
Source code is unchanged, what's changed is the PC rebuild and consequent
re-installatin of SQL Server developer version.
I suspect it's something to do with the provider (at least that's the only thing
I can see in the .Connect string that's not verifiably correct....)
The error looks like this after I trap and format it:
-----------------------------------------------------------------
12/30/03 21:34:30v0.71 Userid: UPQC on SAG
Proc: basADO: ADO_ConnectionCreate
-2147467259: [DBNETLIB][ConnectionOpen (Connect()).]SQL Server does
not exist or access denied.
Errors encountered when trying to connect:
''''''''''[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or
access denied.
----------Connect String:
Provider=SQLOLEDB.1;SERVER=SAG;DATABASE=TRETS;UID= Trets;PWD=trets
-----------------------------------------------------------------
Can anybody see anything obvious to look for?
I'm thinking I need to know how to verify/validate the presence of provider
"SQLOLEDB.1"... But how?

I've got SQL 7.0 installed on a desktop to develop DTS packages. I've been using it fine for a month or so. Now, all of the sudden, I cannot connect to the server using Enterprise Manager, SQL Analyzer or anything. I get an error stating 'Connection could not be established: ConnectionTransact(GetOverLappedResult())'. The error log states that the max number of connections has been reached. Also, when restarting the server, there is an inticonfig statement that's says it's only allowing one connection. Why? Nobody/nothing else is connected to this server. How do I change it so it'll allow more than one connection? I can't connect to change this setting.
Any help would be appreciated.
Thanks,

Hi,
I'm using SQL Server 7 and have it installed on one PC, Not networked.
Without any explanation Enterprise manager won't let me look at my databases. It lets me look at a server on the web but not my own Server on this PC.
It has worked without any problems until now. I receive this message when I try and look at the servers databases.
**A connection could not be established to H3G5Z8- Cannot open user default database <ID> using master database instead.
Please verify SQL Server is running and check your Server Registration properties.
*********************
Total mystery right out of the blue.
Appreciate any help you could give me.

I have the following code in my ASP program
dbRows = Server.CreateObject("ADODB.Recordset");
dbRows.Open( dbCmd );
dbCmd.Parameters.Delete("@reset");
newUser=((dbRows.EOF) || ((!dbRows.EOF) && (dbRows("isActive").value != 1)) )
if ( newUser ) {
if(Request.ServerVariables("SCRIPT_NAME") != "/profile_edit.asp" ) {
Response.clear();
Response.Redirect("/newuser.asp");
}
} else {
Session("logon_user") = Request.ServerVariables("LOGON_USER")+"";
Session("fullname") = dbRows("full_name").value;
Session("email") = dbRows("email_address").value;
Session("q1") = dbRows("q1").value == " " ? "" : dbRows("q1").value;
Session("q2") = dbRows("q2").value == " " ? "" : dbRows("q2").value;
Session("q3") = dbRows("q3").value == " " ? "" : dbRows("q3").value;
Session("ct") = dbRows("ct").value == " " ? "" : dbRows("ct").value;
Session("so") = dbRows("so").value == " " ? "" : dbRows("so").value;
Session("graphic_level") = 3;
Session("er_view") = dbRows("er_view").value;
dbRows.close();
gLev=Session("graphic_level");
dbCmd.CommandText = "knet_user_setLastLogin"
dbCmd.Execute();
This same code used to work but doesn't anymore. The connection times out and the error points to the dbCMD.Execute command. Here same things I have found:
1. If I point the database calls to the development server it works. If I point the database calls to the production server it fails. I am to get to production through other calls just fine.
2. If I comment out the dbCmd.Execute or dbCmd.CommandText = "knet_user_setLastLogin" seperately the code works.
What is the dbCmd.Execute doing when it is called?
Could it be a problem with the store procedure?
Could it be a software upgrade on the Database server that is causing the problem?
Your help will be greatly appreciated.
Thanks,
Craig-

Hi all,
I've installed SP2 on my server. If I run the package on the server, the package worked there before the installation of SP2. Now with SP2 it doesn't work anymore. In VS2005 on my computer the package works before and after the installation of SP2.
He gives an error with the execution of a sql-task on an oracle server:
Error :Executing the query "insert into cube_content values (trim(?), trim(?), trim(?), trim(?), trim(?), sysdate) failed with the following error: "ORA-01401: inserted value too large for column". Possible failure reasons: Problems with the query, "ResultSet property not set correctly, parameters not set correctly, or connection not established correctly.
Anybody an idea?
Thanks,
Dennis

I have an ASP.NET/ADO.NET page i wrote. It was based off of the development database during most development, and it switched over seamlessly to the production database.
Except for yesterday, when i went back to edit the page. It simply stopped returning results on my queries. To see if it was caused by bad values being passed to the sqldatasource, i tried it in the "Configure Data Source..." window, and it returns zero rows. When passing all of the exact same parameters to the same procedure in the same DB engine, even using the same login information, it works.
Just not in my ADO.NET app anymore...
Can anyone tell me what the hell could be going on here, please? I already rebuilt the page from an older version this morning, being very minimal on changes, and the last thing i changed before it stopped working was the connection string... *BUT* I have triple-checked that against the canon string we have always used in every working copy.
I'm losing a lot of hair over this . Any help would be greatly appreciated.
Thanks in advance

Hi,
I'm unsure what happened, but I'm using SQL Server 05 Developer Edition. I've been working with a local database where I tried to add a clustered index on a huge table (about 50M records). Well, I had to stop the query since it was maxing out my work computer. Since then, I've been unable to open the database or run queries against it.
When I open SQL Server Management Studio the database says In Recovery. Once it's done, when I try to expand tables, I eventually get this error:
TITLE: Microsoft SQL Server Management Studio

Hello,
Yesterday I made the HelloWorld_CLR sample work and figured today I would create a simple windows service to immulate its functionality. When this was not working I tried the sample again and it stopped working. I have tried several things and nothing has worked. Has anyone seen this before or have any ideas on how I can get it working again? I even tried removing SQL Server and its samples then reinstalling to give me a clean slate but that did not work. I did not make any changes to the software nor did I make any changes to the database however the sample did so I need to make sure I can fix this incase it happens in development not to mention I need to continue development.
The Client Queue is normally empty but sometimes has a request to two in it. The Server Queue has alot in it that are both Request and an unspecified type or has a URL for a type. I would paste it in but it takes too much space. Please let me know if you have any ideas because I am not sure what else to try.
Bellow is a sample of the output from running this sample.
Connecting to SQL Server instance
Connected to SQL Server instance
Transaction 1 begun
Dialog begun from service (HelloWorldClient) to service (HelloWorldService)
Message sent of type 'Request'
Transaction 1 committed
Transaction 2 begun
Waiting for Response....
No message received - Ending dialog with Error
Transaction 2 committed
Connection closed - exiting
Press Enter to Exit
Thanks,

Hi,
I installed the dts designer component for 2005 so I could migrate over some 2000 packages and was able to successfully open and run dts packages under 2005.
Then all of a sudden I get this error msg and can't open them, migrate them, export them, etc:
"here were errors loading the package "MyPackageName":
[DNETLIB][ConnectionOpen (Invalid Instance()).] Invalid connection.
(Microsoft.SqlServer.DtsObjectExporerUI)"
That is not a typo, it actually says "here were errors..." instead of "There were errors..."
I've tried the obvious, repair the dts designer component and rebooting, no luck.
Anybody seen this?
Hope this is the right group to post to...
Thx

When I try to run my report manager which is in my local machine, I get the following error message.
The report server cannot open a connection to the report server database. A connection to the database is required for all requests and processing. (rsReportServerDatabaseUnavailable) Get Online Help
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)
I can not open Report server data base and reportserver temperary data base, even in Management Studio. I can not see them there anymore.
Also When I try to open data base engine in my local machine through Management Studio, I can not open it. I get the following error massege.
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) (.Net SqlClient Data Provider)
Recently, I changed data base connection properties of all my reports. coz earlier I used a data base which was in the local machine. But then I connected all my reports to the same data base which is on another server. Then I changed all connection properties of each report. After that I deleted the data base in the local machine.
Would that be the reason for this problem?
Also SLQ server(MSSQLSERVER) and SQL Server Agent has been stopped running. I can not start it from SQL Server Configuration Manager.
Please can anyone tell me how to fix this problem and get my work done as usual?

Hello all!
I've a problem with my database. Till yesterday the option for Auto Grow of Database (10 %) was working very fine, but now it seems to be some problems with it. Finally I had to specify a restricted size for the database and then it again startd to give me some space in the database to write in. Ideally it should have worked automatically, isnt it ???
There is no problem with the space on the drive, I still have some 76 gb of free space there ...
Thanks in advance ...

Hi everyone,
I've a problem which I think a lot of SQL Server 2005 users had already ...however I didn't found any answers so far. Maybe anyone of you might know.
I have installed SP1 for SQL Server 2005 on 2 systems, one is an Enterprise Edition (english) on a Win. 2003 SP1 system and one is a Developer Edition (also english) on a Win. XP Prof. system.
On both systems the installation process of the SP1 worked fine except that it gave me the message "Reboot required" on the step installation of SQL Server Native Client.
After my reboot I reexecuted the installation of SP1 with the result of no error nor reboot message. Everything seemed fine....
However when I checked the status of the services I recognized that the SSIS has switched from LOG ON AS ...my specific login.... to NT AUTHORITYNetworkService and the automatic startup failed.
I tried to change the login to my previous login which also failed. It tried to change it to any other possible login but the startup with all logins failed with the error message:
The service did not respond to the start or control request in a timely fashion.
The event log of the system does tell me the same error message. The summary log of the SP1 installation doesn't show any error or warning message except "Failed to read registry key: Debug". Enclosed is the log file:

Hi,
Made the jump from SQL2000 to 2005 - i'm not a DBA but like to play around with such nice tools- and tried to convert my DTS package into a 2005 one.
I've got a csv file containing some log in information.
As users log in everyday, this keeps getting added to the file.
I'm only interested in the latest appearance of a certain machine on the network so i filter by creating an unique Index
the CSV file get's imported into a temporary table first and then i executed the following on SQL2000
CREATE TABLE [patchings].[dbo].[allfilter] (
[username] varchar (20) NULL,
[machine] varchar (20) NULL,
[os] varchar (20) NULL,
[sp] varchar (20) NULL,
[date] smalldatetime NULL,
[time] varchar(10) NULL,
[logonserver] varchar (20) NULL,
[country] varchar (20) NULL,
[domain] varchar (20) NULL,
varchar (20) NULL,
[brand] varchar (20) NULL,
[model] varchar (20) NULL,
[speed] int NULL
)
CREATE unique INDEX [my filter] ON [dbo].[allfilter]([machine], [os]) with ignore_dup_key ON [PRIMARY]
go
insert into "Allfilter" select * from temptable order by date desc
This worked perfectly in SQL2000.
when i try to do the same in SQL2005, it doens't start inserting the most recent machines (filtered on the date) but machines at random
selecting the select * from temptable order by date desc shows me the correct order for the machines by date so i'ld presume that it adds the most recent combination of machine and operating system from "today" and ignores the older appearances.
if the temptable contained for instance..
MY-MACHINE MY_USER Windows XP Service Pack 2 2006/06/13 10:02:34 Mydomaincontroller BE MY_DOMAIN my_ip IBM type 2593
MY-MACHINE MY_USER Windows XP Service Pack 2 2006/06/15 9:59:59 Mydomaincontroller BE MY_DOMAIN my_ip IBM type 2593
MY-MACHINE MY_USER Windows XP Service Pack 2 2006/06/16 12:33:09 Mydomaincontroller BE MY_DOMAIN my_ip IBM type 2593
MY-MACHINE MY_USER Windows XP Service Pack 2 2006/06/19 10:48:56 Mydomaincontroller BE MY_DOMAIN my_ip IBM type 2593
MY-MACHINE MY_USER Windows XP Service Pack 2 2006/06/20 11:03:49 Mydomaincontroller BE MY_DOMAIN my_ip IBM type 2593
under SQL2000 i'ld see one record in the final "allfilter" table
MY-MACHINE MY_USER Windows XP Service Pack 2 2006/06/20 11:03:49 Mydomaincontroller BE MY_DOMAIN my_ip IBM type 2593
under SQL2005 i don't see the last one though coding is the same
MY-MACHINE MY_USER Windows XP Service Pack 2 2006/06/16 12:33:09 Mydomaincontroller BE MY_DOMAIN my_ip IBM type 2593
I guess i'm missing something here but what?

Hi,SQL Server 2000 SP3Windos 2000 Server SP4I have a DTS package that imports data from a dBase IV databse withfiles located in two folders (dBF1 and dBF2). I use a transform datatask to transform the data.They were running properly, but last week we installed W2K SP4, andnow the transform task for files from dBF2 are not working properly.I have two tranform tasks to extract data from files in dBF2 folder.If I double click to open the transform data task of either of them,Enterprise Manager crashes with the errrormmc.exe applicatio ErrorThe instruction "xxxx" referenced memory at "xxx". The memory couldnot be read.Althoug the transform task for one of the files will run, the otherwill not run giving the messageError Source: DTS packageCatastrophic failureAlso, I have an Access database that has links to the same dBasefiles. For files from dBF2 folder, I'm able to see the data from oneof the files, but if I double click to see the data from the other,access crashes with no specific error message. Nothing has changed ondBase related files (permission wise).The transform tasks to extract data from the other dBase folder (dBF1)files are working fine, and data is accesible from Access.Any advice how to tackle this one?

I use ASP.NET 2.0 and SQL 2005, the SQLCacheDependency didn't work stable for me, it usually works and after a while, it stops working. Recently, It doesn't work. Today I reset service broker by
Alter DB set new_broker
It seems all work, but too early to be happy, it doesn't work now anymore. I don't see any record in
sys.transmission_queue
And I don't see new entries in
sys.dm_qn_subscriptions neither when I modify a record which bind to SQLCacheDependy.
I see some errors in log like
Message
The query notification dialog on conversation handle '{8F8CC642-6340-DB11-8F09-0014227B7B80}.' closed due to the following error: '<?xml version="1.0"?><Error xmlns="http://schemas.microsoft.com/SQL/ServiceBroker/Error"><Code>-8490</Code><Description>Cannot find the remote service 'SqlQueryNotificationService-f79776f7-9ca5-4c5f-8a66-0d81f7673683' because it does not exist.</Description></Error>'.
Any idea how to find out the problem?

1) After a couple of months of work SQL 2000 server stops to increment @@cpu_busy. If you query it you€™ll get a constant value as well as error:
select @@CPU_BUSY
Arithmetic overflow occurred.
134217727
2) If you execute sp_monitor you'll get nothing but errors:
Arithmetic overflow occurred.
Arithmetic overflow occurred.
Arithmetic overflow occurred.
This happens only on multiprocessor machines. SQL Service pack 3. The only way to fix it is to restart the SQL service. If you have a performance tool based on that value, like Idera's SQLdm- sorry, it will show zero.
Is there a fix from MS for that?

Hello there,
I've some really big problems with SQL Server 2005 Express. I Recently, I had 2 instances on my machine, one was a SQL Server 2000 Developer and the other a 2005 Express Version. The 2000 version was not necessary anymore, so I unstalled it, since then, the Express version keeps having probems.
Under the Server Properties -> Database settings -> Database Locations I've changed the path to D:sqldatamssql, but now, the programm always takes the "C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLData" to store and load the databases, no matter what I do.
And there are more problems see here:
Restoring does not work=======================
I wanted to restore a database called "fw40_admin" from a backup file (.bak), but that didn't work at all, it always says this as an error:
"System.Data.SqlClient.SqlError: The operating system returned the error '5(error not found)' while attempting 'RestoreContainer::ValidateTargetForCreation' on 'D:sqldatamssqlfw40_admin.mdf'. (Microsoft.SqlServer.Express.Smo)"
But as soon as I type in the installation path "C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLData" inside the "Restore As" under "Options", it works.
Why does the backup only work in "C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLData", BUT the database locations under the server properties is indicated with "D:sqldatamssql"????
Attaching does not work=======================
Attaching an existing database does not work either. Most databases (mdf) are located on the path D:sqldatamssql, but as soon as I press
Attach Databases -> Add
The dialog window appears with the "D:sqldatamssql" path, but it is unable to find any *.mdfs altough THERE ARE .mdfs in this directory. But Express can find databases in the selected installation: "C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLData".
Why can't Express see the directory on the D: partition???
What is wrong? Here? Can anybody help me?

I am having trouble creating a connection to an MS SQL 2000 database located on a server at the hosting company I'm using, with code running from my localhost. It works when the code is executed on the server at my hosting company, but not when it is executed locally, on my computer. Also, I can't connect to the database using Enterprise Manager. The error I get is this:
SQL Server does not exist or access denied
It has worked before, so I don't understand why it doesn't anymore. It's not a firewall issue, since I have tried to connect with my firewall disabled as well.
Any tips or ideas?

Hi,Just recently I am getting the following error when trying to connect to an SQL DB: Exception has been thrown by target of an invocation. This happens even if I create a new website/solution. Procedure I use:open server explorer and click on create a new connectionchoose SQL server from the listenter my IP address and credentials, click on test and everything is fine. When I go to select the DB the dropdown box is empty, if I type in my database name and click on ok I get the following message:Exception has been thrown by target of an invocationI know it is nothing to do with SQL or credentials as I can create a datasource to my SQL server using my colleagues computer!I have removed VS 2005 from my computer and reinstalled only to be met with the same problem.reinstalling my computer is a last resort!Any ideas?Cheers, Ps, I can connect to my DB using VB code behind.

do we have to create connection and assign it to command object before creating SqlCacheDepency? chek the code below. SqlServer is not invalidating cache when there is update. When i create Dependency using command object, at that time command object does not have connection. It will assign connection to command object in Excute method
SqlCommand cmd = new SqlCommand(commandText);cmd.CommandType = CommandType.StoredProcedure;SqlCacheDependency cacheItem = new SqlCacheDependency(cmd);DataSet result;result = DBHelper.Execute(cmd);HttpRuntime.Cache.Insert(cacheItemName, result, cacheItem);

I am testing RS2008 CTP6.
When I view a Adventureworks sample report (e.g. company sales) I get this errormessage when I use the option "Impersonate the authenticated user after a connection has been made to the data source" :
Cannot create a connection to data source 'AdventureWorks'.
Must declare the scalar variable "@ImpersonatedUser".
All other connection options without impersonate works fine.
Any idea what can cause this problem?
Thanks in advance.

Why is it that sometimes I get this error and sometimes not after I deploy the same shared data souce to my Report Server?
Even if I try deleting the datasouce through Report Manager the redeploy it from VS 2005, it still errors out when I run my report. I am able to run my report fine in VS.
An error has occurred during report processing.
Cannot create a connection to data source 'mydatasourcenamehere'.

Hi, i already create a connection to sybase(ASA) with odbc from ssis (from "data sources" section). but when i try to make data flow source it cann't. so i try to make a connection using "data source views" but when the process comes to end, it becomes error. from my analysis, the Sybase db cannot accept sql command with "[]", because in the fase "data source views" i have to select one or more table, and the default microsoft is using "[]", like: select * from [dbo].[customer], but sybase db cannot handle this. does anyone have the solution for this? Thanks.
Sincerely
Yugicm

I cannot get this error resolve either for myself or any users, and I'm actually part of the Admin group! Furthermore, a user with whom I'm tring allow to view this report keeps getting prompted for their windows username and password. I thought that since this datasource was set to Windows Authentification that it would just pass it through?
I'm pulling my hair out at this point:

Also As far as I know, I've given sufficient permissions to the right logins and right users on my SQL Databases and related stored procs that the datasets (not datasource) run

Hello everyone,
I posted the same issue before, but I couldn't find the solution yet. I am posting this agian cos I tried almost everything and I am not able to solve the issue.
Let me explain what is happening here:
Server A - is my development local machine
Server B - is the remote reporting server, where all reports are deployed
Server C - is where the databases are located
- After successfully deploying the project (the reports and datasources) on the remote server and try to run the report , I am getting the following error message
An error has occurred during report processing. (rsProcessingAborted)
Cannot create a connection to data source 'dsCallB'. (rsErrorOpeningConnection)
For more information about this error navigate to the report server on the local server machine, or enable remote errors
- I tried to deploy and run the same report on my local machine report server(Server A), which is still accessing the same database from Server C. This works fine.
So from this we can understand that A ==> B ==> C is not working, however A ==>C works fine(using Server A as a report server).
I almost tried all the possible solutions that are posted on the forum, such as storing the credential information on the report server (server B), created a data source, which is not a shared data source, on the report server level e.t.c. and I ended up with nuthin.
The weired thing is that there are existing reports that are already created and deployed(by somebody else) in the report server (server B) , which access the database on Server C. These existing reports run with no problem, even I can create a report which uses the existing data source and runs perfectly. However, when I create a new report which uses a different data source (from Server C), and deploy it to Server B and tried to run it, the above error message comes.
Please let me know if you have any idea.
Thx.
