Cannot Set Connection Property Of Backup Database Task If Connection String Is Customized In Connection Object
I added a connection (ADO.NET) object by name testCon in the connection manager - I wanted to programmatically supply the connection string. So I used the "Expressions" property of the connection object and set the connectionstring to one DTS variable. The idea is to supply the connection string value to the variable - so that the connection object uses my connection string.
Then I added a "Backup Database Task" to my package with the name BkpTask. Now whenever I try to set the connection property of BkpTask to the testCon connection object, by typing testCon, it automatically gets cleared. I am not able to set the connection value.
Then after spending several hours I found that this is because I have customized the connection string in testCon. If I don't customize the connection string, I am able to enter the "testCon" value in the connection property of the BkpTask.
Is this an intrinsic issue?

CustomData Property On Connection String?
Analysis Services has a CustomData connection string property. You can put anything on it, then inside an MDX query you can use the CustomData() function to retrieve whatever was on the connection string. This is helpful for passing in a security token. Is there anything equivalent for SQL Server?

I have been trying to host my website on Go Daddy for about 3 weeks and I have cleared several problems but this one remains.

Edit Connection Manager Connection String At Runtime With C#
This is the first time I have used SSIS, so please bear with the ignorance. I have a super simple package that inserts x000's of rows into a temporary table. The data source is a file that the user will upload. I need to be able to tell the package what file to upload. I'm thinking the simplest thing would be to edit the connectionString property of the SourceConnectionFlatFile at runtime. Is this possible? What form should the file path be in (UNC, other)? And, are there any other considerations I should be aware of? Thanks!

How To Re-use Connection Manager ADO.NET Connection In A Script Task?
I'm currently using: Dts.Connections.Item("myADO.NET connection").AcquireConnection(Nothing)Dim conn As New SqlClient.SqlConnection(Dts.Connections.Item("myADO.NET connection").ConnectionString) conn.Open() This seems silly, in that I'm not really using the same connection, but using the connection string of a connection that already exists. And, for my purposes, it's not working currently, because I've switched from Windows Authentication to SQL Auth... and the password isn't coming over in the ConnectionString property.How do I re-use the exact same ADO.NET connection I have in my connection manager in a script task? That's the recommended way to go, right?

Variable Connection String For OLE DB Connection
Good Morning, I hope that I am just missing a step in the process somewhere. I have established a string variable called DatabaseServer and another called DatabaseName. In the OLE DB connectionstring expression I have the following: Code Snippet "Data Source=" + @[User::DatabaseServer] + ";Initial Catalog=" + @[User::DatabaseName] + ";Provider=SQLNCLI.1;Integrated Security=SSPI;Auto Translate=False;" My understanding is that changing the variable from SERVERA to SERVERB should repoint the connection. (Test to pre-production to production in my current promotion environment.) This should also take effect in any dataflow task using the database connection above right? When I try to repoint the server variable (and only the server variable) I am either a.)throwing errors saying the original connection cannot be found in the data flow task, or b.)the job appears to be processing fine, but the repoint did not take place and data is still flowing to the original server. Can anyone offer suggestions as to what I am missing? The properties values in the DB connection: ConnectionManagerType is OLEDB DataSourceID is blank DelayValidation is False (Setting to true changes nothing in my test) Expression for ConnectionString is (see above) RetainSameConnection is False SupportsDTCTTransactions is True (and appears to be unchangeable.)

Is There A Sql Database Function To Check Connection String?
Im working on a db library and I have everything working, what Im wanting to do is though is add a method that can check a connection string to make sure it is actually working. Right now, I have it doing a simple select * query to a particular table and returning true or false if an exception is caused. But I want to make the library as generic as possible, so is there another way to test teh connection string and tell if its working or not?Thanks,Cedric

How Doo I Get Database Connection From SSIS Script Task?
When I try this code in an SSIS "Script Task": Dim dbConnectionManager As ConnectionManager = Dts.Connections(0) Dim dbConnectionRaw As Object = dbConnectionManager.AcquireConnection(Nothing) Dim dbConnection As OdbcConnection = CType(dbConnectionRaw, OdbcConnection) I get this error: Unable to cast COM object of type 'System.__ComObject' to class type 'System.Data.Odbc.OdbcConnection'. Instances of types that represent COM components cannot be cast to types that do not represent COM components; however they can be cast to interfaces as long as the underlying COM component supports QueryInterface calls for the IID of the interface. I'm just trying to get a basic database connection from the DTS package in my script task. Is there a better way to do this? Preferably, I would use ADO.NET rather than the old COM stuff. However, if SSIS still requires the use of COM, that's fine as well, as long as I can fix the above code. Thanks in advance!

Then I copied this connection string to the code, the connection couln't be made. I feel very confused. I am wondering if I need to add ASP.NET user to SQLExpress. But I don't know how to do it? Can anyone please help me out! Many thanks!

Connection String For Remote Database Connectivity(SQL Server2000)
hai, I am working on ASP.NET 2003 with SQLServer2000. My application requires to be connected to the Database which is there in my Headoffice. My SQLServerName is "MyDBServerTestDB" Database Name is "WebTO", UserID="******" and Password="******" My Remote Server IP Address is "192.168.1.2" and its Static IP is "58.93.61.235" I have specified the Connection string for my Remote Server as "Provider=SQLOLEDB.1;Server=58.93.61.235TestDB;UID=******;PWD=******;Database=WebTO" (or) "Provider=SQLOLEDB.1;Server=58.93.61.235TestDB,1433;UID=******;PWD=******;Database=WebTO" (1433 is the Port number of the Remote SQLServer) but it is giving the error " SQL Server does not exist or access denied". if i execute the same application at my Headoffice (Remote Server) by changing the Connection string as "Provider=SQLOLEDB.1;Server=192.168.1.2TestDB;UID=******;PWD=******;Database=WebTO" then, it is working fine. Can anyone tell me where i went wrong or what i have to specify in my Connection string so that i can access my Remote Database Server. Thanks in Advance, Srinivas.

[HELP!] How Do You Make The Database Path Relative In The Connection String?
Hi everyone, I am working on a Hospital Information System project with a team of 6.Each one of us builds or modifies a part of the system and shares the project over a common repository. The problem here is that we use the absolute path of the database in our connection string. Although the directory structure of our project is the same for each member, since the main project folder itself is stored in different locations on each person's computer (for example, one may have it stored in c:My Documents and the other in d: My Documents), we are forced to modify the connection string manually each time someone else from the team updates the repository with the database. How do we make the path of the database relative so that we don't have to modify the connection string manually each time after receiving an update from the repository? Your help is greatly appreciated.

Connection Manager Property Expression Editor
Is it possible to use a property, say name, of an object ( say the connection object) in the "Property Expression" of that object? I would like to modify the Connection String property of a flat file connection manager to append date to it. To do this I need to be able to use the Name property of the connection manager in the Property Expression editor. How ever I get an error that it does not recognize name, it almost seems to suggest I can only use variables. I find it hard to believe since it seems like common requirement to be able to use properties of an object (connection manager) in modifying other properties of the object. Any help would be greatly appreciated. Thanks.

Provider Specific Db Connection Property Page
Hi all, As part of out solution we provide a tool that allows the end user to create a connection to their specific database so that they can tell us about job information specific to them. Once we have this information, we will generate a query that we will use to periodically transfer data from their database to ours. So there's the background. Of course, we could be connecting one of many possible databases for each client, so we are using ADO.NET's Abstract DB classes and the factory objects to allow us to connect to any kind of database using any of the many .net providers out there. When you are setting up a database connection in any connection manager, for example the one in visual studio or the one in SQL server management studio. whenever you select a specific provider, a connection string property page seems to be presented for that particular provider. Now i assume that the connection manager somehow gets the connection properties page by calling a method or accessing some property in the provider assembly, buit i just can't find it. I would rather use the providers connection property page rather than create my own if i don't have to, so does anyone know how to access this page? Any help on this, as always, is greatly appreciated. Paul.

How To Change Configured Value For The ServerName Property Of A Connection Via DTEXEC
I am launching a package the following way: DTEXEC.EXE /SQL "ProcessReportingDatabase" /SERVER RTG23SQLDB01 /REPORTING V /SET "Package.Variables[User::RunID].Value";35 /SET "Package.Connections[RSAnalytics].Properties[InitialCatalog]";"Fnd Prj 1 Dec29" /SET "Package.Connections[RSAnalytics].Properties[ServerName]";"RTG23SQLDB01UAT1PROD" The problem does not happen with the [User::RunID] variable or the [Initial Catalog] property of my [RSAnalytics] connection object. But I am not successful in setting the [ServerName] property. What happens when executed is that the package retains the ServerName property of the deployed package (Value="RTG23SQLDB01UAT1QA"), instead of what I pass in via DTEXEC??? Is ServerName read-only or something? I've tried configuring the package connection to RTG23SQLDB01UAT1PROD and creating a package configuration that I specify in place of the /SET - but to no avail as well! This package has to work against 10 instances. I really don't want to have to create a separate package for each instance, and then a hack to figure out which one to call. TIA - Dave

Changing The ConnectionString Property For A File Connection Manager
I have a package that I plan to run against about 700 databases to look for anomalies. I have several package variables in place that are passed in at runtime. One of them will hold the path and filename of the error log for the current database in process. I want each database to generate it's own error log for documentation and research purposes. However, when I run the package, it continues to use the path and filename that I entered when I created the File Connection Manager. I am trying to update that value in a Script Task by using the ConnectionManager class and setting the value for the "ConnectionString" property. This method is working for the OLEDB Connection Manager (which tells the package which Access database to process), but not for my File Connection Manager. Please help! DO

Problem Configuring Password Property For Oledb Connection.
I'm creating an xml configuration file to hold the connection string including the password (sql server authentication). My package protection level is set to 'EncryptSensitiveWithPassword'. I set up my connection manager and I check the 'Save my password' box. The 'Test connection' button reports that the connection is OK. I enable the package configurations and I go through the Package Configuration Wizard and I specify 'xml configuration file' and I choose 'Specify configurations settings directly' and I specify a configuration file name with the same directory as the package. I check the 'ConnectionString' property and the 'Password' property and then click 'Close'. Then I save my package changes. Now I look at the xml configuration file in a text editor and I see the Password property has an empty element: <ConfiguredValue></ConfiguredValue> Is it supposed to be empty? When I right-click the package in solution explorer and pick 'Reload with upgrade' then I have to enter the password, but the validation fails with 'Acquire connection' error. Should I just be saving the 'Connection string' property, or should I save all the connection elements (i.e. ServerName, UserName, Password etc.)? If I edit the xml configuration file and I type the password into the <ConfiguredValue> element above, and then I do 'Reload with upgrade', then the 'Acquire connection' validation error goes away. Could this mean that I am not able to encrypt the password? Thanks.

Connection Strings, Trusted-connection VS Username-password, SQL Server 2005 Express
All -- Please help. I have some questions about connection strings. BACKGROUND... Note that I am using the "SQL Native Client OLE DB Provider", SQL Sever 2005 Express, ASP.NET, C#.NET, and VS.NET 2005. Note that I do not want to use the "Attach a database file" type of connection string. Note that I am using the site http://www.ConnectionStrings.com as a reference. Note that this "Standard security" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Uid=MyDatabaseUser;Pwd=MyDatabasePassword;" />...does not work and causes the following run-time error...A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.) Note that this "Trusted connection" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Trusted_Connection=yes;" />...works but is less-than ideal because it uses a Trusted Connection rather than a Username/Password combination. QUESTIONS... (A) What exactly does the error in Item 4 mean? (B) Do 4 and 5 imply that one must use a Trusted_Connection for all SQL Server 2005 Express connection strings when the database does not reside in the web application's App_Data folder or use a "Attach a database file" type of connection string? (C) Are there any alternatives? (D) What do you suggest? Please advise. Thank you. -- Mark Kamoski

SQL Connection In Vista With Trusted Connection Fails Under Local System Account Until Reboot
Hi All, We are using the Windows Task Scheduler as a substitute for the SQL Server Agent, which isn't available in the Express edition. The scheduled task just calls a batch file, which in turn, runs a stored procedure using osql with the -E option for a Trusted Connection. SQL Server Express has been installed using the defaults, which means the service is running in the "NT AUTHORITYNETWORK SERVICE" account. The scheduled task we create is set to run using the "NT AUTHORITYSYSTEM" account. Now we find that on Windows Vista (tested using Ultimate Edition) that the scheduled task fails to run the stored procedure until the machine is rebooted the first time after installing SQL Server Express. When I say "fail", I mean that the stored procedure isn't executed. The scheduled task however completes and reports no errors. On Windows XP, we do not run into this problem so I suspect it has something to do with the UAC in Vista? We further found that after installing SQL Server Express and creating the scheduled task in the "NT AUTHORITYNETWORK SERVICE" account, the scheduled task (and stored procedure) runs fine WITHOUT requiring a reboot. Can anyone explain why a reboot is needed to get SQL Server Express to run the scheduled task correctly under Windows Vista and the SYSTEM account? Any help or thoughts greatly appreciated.

Jdbc Refuses Connection With 'user Not Associated With A Trusted SQL Server Connection' Message
When using jdbc with IntegratedSecurity, I run into this problem when the machine is not part of a domain & gets its IP address via dhcp. Is this expected behavior or a bug in the jdbc driver. The SQLServer and client application are installed on the same machine and a local admin is logged in, running the client app. If I change one of the two parameters mentioned above, the connection can be established leading me to believe this may be intentional for security issues. Am I correct?

ExecuteReader Requires An Open And Available Connection. The Connection's Current State Is Closed.
I am accessing SQL2005 with C# code using OleDbConnection. A try and catch block catches the following error once a while between the Open() and Close() of the connection: ExecuteNonQuery requires an open and available Connection. The connection's current state is closed. I do not even have any idea where to start to debug this. The ExecuteNonQuery() runs a delete SQL query. It works 99.9% of the time. I do not see anything wrong when this error happens. Any hint would be greatly appreciated.

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 ColA (Source) PARTY_NO (Destination) 71167300 71167296 70329000 70329000 70410000 70410000 Any ideas people?
