When the databse file's "copy to output" property is set to "copy always" my data is not saved and when I
change it to "do not copy" it gives me the error "cannot attach the database file", and does not open my connection.
I dont know what to do.....
Hello,
We have a strange problem occurring in an environment at a remote client that we're looking into. I was wondering if anybody else has experienced something similar.
We have a COM+ transactional component sitting on a machine that connects to a SQL server machine in the same room (ie no firewall between the two as far as I know, but I'll double check that to make sure).
This component was written in Delphi and uses ADO (sqloledb provider) to connect to the SQL Server. This works 99% of the time. However, there are times where we get the following error when trying to open connection (using the Connection ADO interface):
[DBNETLIB][ConnectionRead (WrapperRead()).]General network error. Check your network documentation
or this:
Connection failure
The error codes associated with these were found in oledb.pas :(-2147467259) $8004D01C and (-2147168228) $80004005
When this happens, it seems to last a few seconds (usually around 10) and then everything comes back to normal. I'm just wondering what could make this happen when the SQL Server seems to be responsive when we try to connect to it using other means. The SQL machine runs Win2k3 sp2 for testing purposes.
Since we were not able to reproduce it yet, I wrote a little application trying to connect to a sql server when it is set on pause. When I run it inside a COM+ transaction, I get the same errors as above right away, the third time I'll get an error telling me that SQL is in pause state, If I run the exact same code but inside a simple vbs application (ie no COM+ transaction), I only get the pause error message sometimes after a few more seconds, and none of the other errors above. Could it be that the COM+ transaction is trying to do other things and these fail so it returns another error? If so, how come after a bit I get the proper message?
Anyways, I'm pretty lost as to why this is happening and how we can try to debug it since we have not been able to reproduce it yet. If anybody has any clues, please let me know.
Many thanks,
Greg
I'm currently experiencing major problems with SSIS when opening and editing large .DTSX package files that contain Exec DTS 2000 Tasks which have the package data loaded internally. I have no issues if I point the task to a .DTS file, or to an actual DTS package on a SQL 2000 server - but if I load the package internally then once the underlying .DTSX file gets over around 17MB or so in size (which doesnt take long making a few edits to even fairly simple packages now and then), I start to experience major issues with VS/BIDS 2005 crashing randomly when I try to perform any action with the package (open, save etc). Things like OutOfMemory exception errors, followed by the properties of Exec DTS 2000 task being deleted, and also sometimes accompanied by messages about the application not being installed properly.
Again its ONLY when the underlying .DTSX file reaches a certain size limit, and only when I've got an Exec DTS 2000 task with the package loaded internally. I've replicated the issue using several different package files on several different machines (even on servers with lots of memory, fwiw).
Can anyone out there help me with this? SSIS - namely SSIS Exec DTS 2000 package tasks - are our lifeblood at my company and this trend of random and serious crashing on large package files is very disturbing to say the least.
thanks,
Wil
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

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)

Dim outHRIDParam As New SqlParameter("@HRID", SqlDbType.Int)
outHRIDParam.Direction = ParameterDirection.Output

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 a loop that can run say 30k times. in there i am using the try / catch / finally blocks to handle ADO.NET Transactions (thanks CADDRE!)Should i open and close the SQL Connection for each record? or open it and close it outside of the loop only once ?thanks in advance, mcm

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.
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 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:

I have a Merge-Pull subscription setup between two SQL 2005 databases. While watching the status messages display for the subscription, I am constantly seeing the following message being displayed:
"The merge process could not connect to the Publisher '{server}:{database}'. Check to ensure that the server is running."
It will display for anywhere between 15 seconds to a few minutes, then it will display the standard "Waiting 60 seconds..." message which is what I'm used to seeing when all is working well.
There doesn't seem to be any network issues that I can identify. I ran a quick script to run ping continuously against the publisher server and verified that the server was constantly "pingable", even when the above message was displayed (which, by the way, was being displayed by using SSMS while connected to the publisher).
Does anyone know what would cause this message to appear all the time - for extended amounts of time, with occasional glimpses of a non-error status?
I'm currently using database mirroring as a hot-standby, without a witness. Everything appears to be running fine, but I'm receiving intermittent errors that appear to state that my servers are loosing connectivity, thus disabling (inactivating) the mirror until the connection has been reestablished.
The errors are listed below, basically, I note a block of log entries for each mirrored database stating that mirroring is inactive for the database(s), next Error 1474, next the connection error, then another block of log entries for each mirrored database stating that the mirroring session is once again active.
Database mirroring is inactive for database 'NetRS'. This is an informational message only. No user action is required.
Error: 1474, Severity: 16, State: 1.
Database mirroring connection error 4 '64(The specified network name is no longer available.)' for 'TCP://SQL01NRS:7024'.
Database mirroring is active with database 'Telephony' as the principal copy. This is an informational message only. No user action is required.
I have confirmed that the sessions are in sync, so am not concerned about the data - but would love to get rid of these errors / disable / enable. I'm assumming that if I had setup a Witness, that I would see the mirrored database flip-flopping back and forth between Principal and Mirror.
Please let me know if I can provide any additional details to assist ...
We just upgraded our accounting packages database from Pervasive 8.1 to V9.11. MY SSIS extract packages were working just fine. Now I am getting several erros stating that some columns cannot be found:
For example, in the [sysdtslog90] table, I have these errors:
Column "CreditLimitAmt" cannot be found at the datasource. or
Column "RsrvRptky" cannot be found at the datasource. (from a different pkg)
The table schemas did not change, the columns still exist. The SQL I use also runs just fine in the client interface.
Has anyone experienced this? The bottom line is that now the extract packages are broken.
TIA.
I have a package that uses a for loop to iterate through an unknown amount of excel files and pull their data into a table. However, there will be cases when the file is corrupted or has some sort of problem so that either the transformation will fail or the excel source will fail.
I have it so that for each iteration if the transform was successful the file is moved to an archive directory, and if it fails the file is moved to a different directory.
But I don't want the package to be marked as failed. For the control flow tasks I have set the individual components to FailPackageonFailure = False, and for the Data Flow tasks I have set ValidateExternalMetadata = False.
It no use to set the MaxErrorCount higher because I can't guarantee how many files will be processed and how many might fail.
Could anyone suggest a clean way to trap these errors? Specifically, the "Cannot Aquire Connection from Connection Manager", which is the excel connection.
Thanks

I was getting the following error
"Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."
so I tried doing the following
SqlClientPermission pSql = new SqlClientPermission(System.Security.Permissions.PermissionState.Unrestricted);
pSql.Assert();
and then I get this error
"Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."
Any idea how to remedy this ?
Thanks in advance

Hello,I have a Win2K3 Server with SS2005 developers edition. I am working on aWindows XP Pro workstation which has SQL Server 2000 installed as well asthe SQL Native Client. I'm using an MS Access ADP to connect to the serverand for some reason it's extremely slow, even to the point of throwing timeout errors and "can't generate SSPI context" messages. I've hit the MSwebsite and found info on the SSPI error, but none of the items thatgenerate the error apply to my situation. I've tried using the surface areamanager to change the connection to name pipes, name pipes and tcpip etc,but no luck.Is there anything I should be looking at or any known issues that wouldaffect this kind of performance?Thanks!Rick

Hi,
I have an reporting services (SSRS 2005) installed locally and I am trying to access it locally through : http://localhost/reportserver, but all I get back is this page.
localhost/ReportServer - /
Microsoft SQL Server Reporting Services Version 9.00.3054.00
Also when I try to connect to reporting services through SSMS I get the following error message.
Cannot Connect to Server ServerNameSQL2005
Unable to connect to the remove server (Microsoft.SQLServer.Management.UI.RSClient)
No connection could be made because the target machine actively refused it(System).
About my set up, I have SQL Server 2005 (SP2) installed in a named instance called SQL2005, I have reporting services set up to run under local system and I have gone through the RS config tool and everything in there appears to be correct. U double checked in IIS that the report server folder is "ReportServer" and not "ReportServer$SQL2005". I have set up full read write permissions to all the virtual directories, to my domain account which is also a local administrator. The user logs in under windows authentication (marked in the directory security tab in IIS, for the virtual directory & the default website).
Whenever I start the service however I get the following errors in the windows application log:
Report Server (SQL2005) cannot create the trace log C:Program FilesMicrosoft SQL ServerMSSQL.3Reporting ServicesLogFilesReportServer__05_15_2008_10_27_52.log.
&
Report Manager cannot create the trace log C:Program FilesMicrosoft SQL ServerMSSQL.3Reporting ServicesLogFilesReportServerWebApp__05_15_2008_10_27_07.log.
Also I am unable to deploy my SSRS 2005 project from BI studio with more errors, I get the following exception thrown in a windows. (I am trying to deploy to the root "ReportServer" folder, not a sub folder.
A connection could not be made to the report server http://localhost/reportserver.
System.Web.Services.Protocols.SoapException: Server was unable to process request ---> System.InvalidOperationException: Unable to generate a temporary class (result=1)
error: CS2001 "Source File "C:WindowsTempc-zsc7th.0.cs" could not be found.....
I don't have sharepoint installed, I do have the dashboard designer for Performance Point Server 2007 installed though.
I have been on this thing for hours, I have tried appending "$SQL2005" on to the end, stopping and starting RS Service multiple times. Change all the permssions in IIS so that the user can full control over the IIS virutal directory. I am at a loss at what else I could try.
Any Idea's?
Thanks!!
Hi all-
I setup a new ODBC connection to MS SQL Server 2000 on Windows XP and keep getting the following errors when I try to
either register a new SQL Server 2000 group within Enterprise Manager or test the new ODBC connection:
Current configuration
- MS SQL Server 2000
-Windows XP
-ODBC 3.85.1117
Errors:
I. Within SQL Server 2000 Enterprise Manager
Error: SQL Server connection open
II. When I test the ODBC connection:
Microsoft SQL Server ODBC Driver Version 03.85.1117
Running connectivity tests...
Attempting connection
[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]Specified SQL server not found.
TESTS FAILED!
Now here is what has me totally confused:
I can use the command line ISQL to access the database on the server and IP is all correct and port is available.
Any tips how to get this ODBC working?
Thanks

For some reason, when I try to delete old DB connections from the connection manager, it causes compilation errors because it is not removing the references from the meta data. I get Object ID errors where it is still trying to find the connection after it has been deleted. I have tried going to the code behind and searching then deleting the invalid reference, but that still does not work. I have a connection for 2 totally different databases that are no longer being used in the SSIS package and I would like to get rid of them.
Suggestions?
Hi,
As I was developing my SSIS package, I created several variables and tasks ( FTP, WMI Reader Task ). I am now cleaning up, deleting unwanted variables and connections in the design window. I save and build the package and when I load the package, I get warnings that these variables are referenced but can't find them and errors that the WMI connection is not found.
When a package calls a sub-package, it stores the absolute path of the child package in its dtsx xml file in a Connection String property. How annoying !!! . When I deploy this to another machine with a different file structure, it becomes a problem. Why can't it store the path relative to the parent package, which would be typically in a sub-directory under the parent ?
These last 2 days have been nothing but frustration and my deadline is slipping. Any help is appreciated.
Thx,

Purpose: Need to import excel source data into SQL Server 2005 tables. Excel source data comes in nulitple excel files with the same structure but different data. I would appreciate someone taking a look at the following information and notifying me of what I am doing incorrectly.
I Inserted a foreach loop container, a data flow task located inside the foreach loop contaiiner, an excel and SQL Server 2005 connections.
After trying multiple times I went the following URL and followed step by step direction on how to connect excel workbooks dynamically: http://msdn2.microsoft.com/en-us/library/ms345182.aspx . I also used http://www.sqlstrings.com/ as a reference when creating the connection string.
Creating a Foreach Loop Container:
1. Opened foreach loop container 2.Set the Enumerator to 'Foreach File Enumerator" and configured the enumerator by setting the directory location and file base name to E:ClientsDep CommBEABEA_Test_Source and *PersonnelExpense*.xls respectively. 3. Clicked Variable Mapping; created two variables called, "ExcelFile", and "ExtProperties" and closed out of the foreach loop container.
I. Created Excel Connection:
Created excel connection called, €œDynamic Excel Connection Manager,€? that initially pointed to one of the excel workbooks.
Went to the connection properties by right clicking the connection manager.
Expanded Expressions and clicked the ellipsis button to bring up property expressions
Chose Connection String in the Property.
Clicked the Expression Ellipsis button.
Put the following inside the Expression multi line text box:
A. "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + @[User::ExcelFile] + ";Extended Properties="" + @[User::ExtProperties] + """
Clicked the Evaluate Expression button to get the following:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=;Extended Properties=""
Clicked Ok button
Inserted a Data flow task inside the foreach loop container.
II. Configured Tasks that is associated with Dynamic Excel Connection Manager or Package:
Set the Foreach loop container Delay Validation to true.
Set the Data Flow Task Container Delay Validation to true.
Set the Dynamic Excel Connection Manager Delay Validation to true.
Set the SQL Server Connection Manager Delay Validation to true.
Set the Package Delay Validation to true.
Package Locale ID set to English
Ran the package after connecting the excel source data flow to the OLEDB destination and have inserted part of the error in this post. Please see below.
Error: 0xC0202009 at Package, Connection manager "Dynamic Excel Connection Manager": An OLE DB error has occurred. Error code: 0x80004005.
An OLE DB record is available. Source: "Microsoft JET Database Engine" Hresult: 0x80004005 Description: "Could not find installable ISAM.".
I modified the connection string after receiving the error by removing the extended properties. The following is the modified connection string: "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + @[User::ExcelFile]
I repeated step I.6 above and received the following expression: Provider=Microsoft.Jet.OLEDB.4.0;Data Source=
I ran the package and received the following error in part: OLE DB record is available. Source: "Microsoft JET Database Engine" Hresult: 0x80004005 Description: "Unrecognized database format 'E:ClientsDep CommBEABEA_Test_SourcePersonnelExpense_OCCs_051007.xls'."
I did not find anything helpful when I searched for the above errors and would very much appreciate anyone€™s assistance on this issue as this issue needs to be taken care of ASAP.
Does anyone have any ideas as to why I received this error and what can I do to resolve this issue?
Your assistance in this matter is truly appreicated!
Thanks!!

I am in the process of importing an Excel Spreadsheet using the natively connection manager in SSIS 2008. Â There is one column however that is causing me grief.
SSIS has natively chosen the problematic column to be a DT_WSTR(255). Â I have gone into the Excel connection manager's Advanced Editor and altered it to be a DT_WSTR(1000) (see image 1 attached).
I am still getting truncation issues though, as per image 2 attached. Â why this is?

I recently updated the datatype of a sproc parameter from bit to tinyint. When I executed the sproc with the updated parameters the sproc appeared to succeed and returned "1 row(s) affected" in the console. However, the update triggered by the sproc did not actually work.
The table column was a bit which only allows 0 or 1 and the sproc was passing a value of 2 so the table was rejecting this value. However, the sproc did not return an error and appeared to return success. So is there a way to configure the database or sproc to return an error message when this type of error occurs?
