Greetings, and Happy Friday. I want to check myself in regards to the proper use of connections in a data flow script component being used as a transformation. I want to ensure that the solution is ideal from a performance standpoint, but more importantly that there won't be any resource leaks from connections that are not being closed or objects that are not being disposed properly.
This transformation script component is writing to a table based on the rows that pass through Input0_ProcessInputRow(). What I'm doing so far is, in the script component script, I've declared a class-level variable of type System.Data.SqlClient.SqlConnection. In the PreExecute() event handler I am initializing this connection with the following code (which comes after the call to MyBase.PreExecute()):
Dim connMgr As IDTSConnectionManager90 connMgr = Me.Connections.JobDB adoConn = CType(connMgr.AcquireConnection(Nothing), SqlClient.SqlConnection) If adoConn.State <> ConnectionState.Open Then adoConn.Open() End If connMgr = Nothing
The adoConn variable referred to there is the class-level variable. So, my first questions:
Is this the best way to initialize the connection? And is that code checking adoConn.State necessary? Can I pretty much assume that the connection manager is going to give me an open connection?
Then in the PostExecute() event handler I have this code (again, after the MyBase call):
If Not (adoConn Is Nothing) Then
If adoConn.State = ConnectionState.Open Then
adoConn.Close()
End If
adoConn.Dispose()
adoConn = Nothing
End If
Next questions:
Is this adoConn variable actually holding a reference to an object whose primary owner is in the connection manager? Is it necessary to close my SqlConnection this way, or is that going to actually close the connection manager's connection?
I'm also wondering whether I need to have this same code in the script component's Finalize() handler also...if there's an error I don't want the resource to leak. Or will PostExecute() fire even if there's an error in Input0_ProcessInputRow()?
I have a package that has a data lfow task. this task imports data from a db2 database (using the IBM Ole DB provider fro db2) and adds it to sql server database table. This package was created on the server. then though version control (using TFS source control) I check out the package on my local machine. and when I open the package I get the foll 3 errors.
Error 1 Validation error. Import Account Num from BMGP_BDR: DTS.Pipeline: The component metadata for "component "DataReader Source" (1113)" could not be upgraded to the newer version of the component. The PerformUpgrade method failed.
Error 2 Error loading BMAG Download Xref Tables - bmag.dtsx: Microsoft.SqlServer.Dts.Pipeline.ComponentVersionMismatchException: The version of component "DataReader Source" (1113) is not compatible with this version of the DataFlow. [[The version or pipeline version or both for the specified component is higher than the current version. This package was probably created on a new version of DTS or the component than is installed on the current PC.]] at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostCheckAndPerformUpgrade(IDTSManagedComponentWrapper90 wrapper, Int32 lPipelineVersion)
Error 3 Error loading BMAG Download Xref Tables - bmag.dtsx: The component metadata for "component "DataReader Source" (1113)" could not be upgraded to the newer version of the component. The PerformUpgrade method failed.
I have a package which reads an Access file from a folder. My connection manager to this file is .NET providers for OledbMicrosoft Jet 4.0 OLE DB Provider.
Package works from my computer. But when I execute it on the server as a SQL Agent job, I get
The component metadata for "component "DataReader Source" (1) could not be upgraded to the newer version of the component. The PerformUpgrade method failed.
I copied the mdb file to a folder on the server which my packages have no problem reading data from.
My packages run under the same domain account as defined in proxies.
I'm on writing a custom data flow component (transformation). For this I need access to an external datasource. As best practice, it seems that you should use a connectionmanager in the package.
But I don't really know how to access them.
I've overwritten the AquireConnections() to lookup in the RuntimeConnectionCollection for the connection managers. But It seems it doesnt get called. If I call it my own, for example in validate (just for debugging purposes) the collection is empty, although there are two connectionmanagers in the package.
What am I doing wrong or has someone a code snippet for me.
Hi I am using OLEDB Connection in script component. I get a login failure when I run the package. I use SQL Server authentication. Do you have to use windows authentication in script component? Thanks
I instantiated a new script component into an existing Data Flow in my SSIS project.
In the Script Transformation Editor, under the Connection Managers section, I associated the name dbConnManager to an already existing Connection Manager in the project.
My Connection Manager is of the type oOLEDB.
I then opened up the script designer and added the following lines of code where it said "Add your code here"
When I test run the project I get the following error and the new script component is red:
Unable to cast COM object of type 'System.__ComObject' to class type 'System.Data.OleDb.OleDbConnection'. 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 know the database connection works since I am using it in a component that executes before this new script component.
I have a script component which loads a file which is in a custom format. The script component is inside a For Each Loop Container and it uses a flat file connection manager. The loop sets the connection string for the connection manager.
The problem I'm having is that the connection string needs to be set to something every time that I start the package but I don't know ahead of time what file there will be, so I get a System.IO.FileNotFoundException error on the script component. If I manually set the variable for the connection string and point it to a file that exists, then the package runs fine but at the end of the package the connection string is set to the last file loaded and this file will no longer exist the next time the package runs.
I am writing a Custom Destination component with a custom UI. The UI contains a combo box which contains the connection names of type €œFLATFILE€?. I also have provided a button which would create a new connection of type €œFLATFILE€? by making a call to CreateConnection method of IDtsConnectionService. The combo box gets properly updated showing the connections of type €œFLATFILE€? but on clicking on the new Connection button the application hangs up. Am I missing something or is there some other way to do it?
The function are the events handlers which are called by the UI.
if (connectionService != null) { ArrayList temp_Connections = connectionService.GetConnectionsOfType("FLATFILE");
args.AvailableColumns = new AvailableColumnElement[temp_Connections.Count]; for (int i = 0; i < temp_Connections.Count; i++) { ConnectionManager runtimeConnection = (ConnectionManager)temp_Connections; args.AvailableColumns.AvailableColumn = new DataFlowElement(runtimeConnection.Name, runtimeConnection); }
args.AvailableColumns = new AvailableColumnElement[temp_Connections.Count]; for (int i = 0; i < temp_Connections.Count; i++) { ConnectionManager runtimeConnection = (ConnectionManager)temp_Connections; args.AvailableColumns.AvailableColumn = new DataFlowElement(runtimeConnection.Name, runtimeConnection); }
I am running SQL 2005 9.0.1399 and VS 2005 8.0.50727.42 (RTM.50727.4200) on Windows Server 2003 Enterprise Edition SP1. Any suggestions would be welcome.
The code sample is an extension to the RemoveDuplicates sample (Dec 2005) which comes along with the SQL Server.
Hi All, I've written a script component that essentially uses a connection manager to connect to a database and executes a stored proc to return a retail price for a product sold in a store. This works fine with small volumes of data. (50 or so executes) When I use larger volumes of data (4500 executes, eventually will be 2.5 million) I get connection pooling errors as follows:-
Timeout expired. 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.
This I can fix on the 4500 data volumes by setting the connection pool to 10000.
My question is... is this the correct way to fix the error, or is there an underlying problem that needs to be sorted? My script code is as follows.
Public Overrides Sub SalesData_ProcessInputRow(ByVal Row As SalesDataBuffer)
Dim InSightConnectionManager As IDTSConnectionManager90 = Me.Connections.InSight
Dim InSightConnection As SqlConnection = CType(InSightConnectionManager.AcquireConnection(Nothing), SqlConnection)
Hi all. Sorry about bothering you again but I have no choice, I'm afraid. This time I have to add a connection manager at runtime. I have a script that examines rows in a huuuuuuuuuuuuge file and it turns out that I will have to redirect different rows into 95 different text files. I would like to avoid the pain of creating the files and connection managers manually. I have a source script component that runs asynchronously (the only way basically it can run as a source) and I wonder whether this time, when I change the connction string on the manager at runtime inside the script, it would run properly. Can anybode tell me, please?
Hi all,I am facing an unusual issue here. I have a stored procedure, that return different set of result when I execute it from .NET component compare to when I execute it from SQL Management Studio. But as soon as I recompile the stored procedure, both will return the same results.This started to really annoying me, any thoughts or solution? Thanks very much guys
Attempting to create a data flow task to copy data from AS/400 (DB2) to SQL2005, using an existing System DSN ODBC connection defined on the SQL2005 host.
Problem:
When adding the DataReader Source component to the package, I cannot assign the Connection Manager. Designer issues the error message:
"The runtime connection manager with the ID "" cannot be found. Verify that the connection manager collection has a connection manager with that ID."
Editing the DataReaderSrc component shows only one row under the Connection Managers tab:
The datareadersrc component editor displays the warning message: "Not all connection managers have been set. Set all connection managers.". Clicking the Refresh button causes the error message to be displayed "The runtime connection manager with the ID "" cannot be found. Verify that the connection manager collection has a connection manager with that ID."
I am prevented from assigning my Connection Manager object the DataReaderSrc.
The package already contains one Connect Manager object:
Provider: .Net Providers/Odbc Data Provider System DSN
The standard flat file connection component does not handle flat files with different column counts on different rows. Since that's the type of file I have to read, I like to create a modified version of the flat file connection manager that can do this. I have found some info in how to create a connection manager. But I can't find anything that tels me how to build one that would be recognized by the flat file source dataflow component.
So how do you build an connection manager that can used by the standard flat file source component? Anyone ever did this or knows were to get the docs?
I know my problem is also solvable by reading the row into a single column and then using a script component to split them but that is not the solution I want.
I have written a script source component and attached a flat file connection. The connection string of which is defined by an expression.
However when I get the connectionstring from the connection in the script it has the default filename value of flat file not the value of the expression. This is proved by passing in the filename variable, and comparing the 2.
The flat file has an expression on the ConnectionString of @[User::filename]
Within a data flow I have a script component that I want to perform some data calls from. I want to execute SQL commands to connections already defined in the package's connection manager.
Is there a way to set my script's connection variable to the connection manager connection? Or, can I use the connection manager connections directly from within the script?
I need you help badly. Iam a student and iam working on "Creating a Mobile Application with SQL Server Compact Edition" http://msdn2.microsoft.com/en-us/library/ms171908.aspx . This tutorial works fine until

Hi:I have a Point-of-sale application that uses SQL Server2000 for the backend.Basically, the users perform various functions boiling down to login (checkpassword from a table) and data entry (insert a food entry). Previously, Iwould open a new ADO 2.7 connection to the database each time one of thesetypes of database accessing functions needed to be performed - but I noticedthat sometimes the DB would freeze the application for 20 seconds or so - oreven cause a timeout error.To fix this, I open a DB connection when the application first starts,keeping it open for the life of the application - each time a function needsto access the DB, it just uses the applications (global) connection that isconstantly open and connected.This seems to have fixed the problem, however, I am curious, is this an OKway to handle the connections - keeping in mind that there are four separatestations - each running the application - at the same time. Therefore, Ihave 4 constantly open connections at the same time.Thanks and regards,Ryan Kennedy
hi.. i have like 50 ssis packages,, most of all have the samne conexion to my target server.,, the user an pwd i'm using is the same for all of them... but the pwd has been changed because of security rules,., the result: these packages will no longer execute correctly .. is there anyway i can change this conexion for all the packages without doing it manually? and if so.. how??

but how do i get the cache connection content ?I want to look in the content in a script component code.Â
When i try to connect to Integration Services on a SQL 2005 Machine, it Gives me a Class not registeed. But i can connect to SQL 2008 Integration Services without a issue. I tried Restarting the 2008 machine and Also Reinstalling the SSIS Piece and also Reinstalled SQL 2008, but nothing seems to Help.
I have a problem establishing multiple connections in Management Studio. It is hard to describe, but it happens consistently when I try to open a new connection.
I can connect to the database engine successfully but when I try to open a "new query" the application just goes away without any errors. Both of these features requires their own connection and currently I cannot open both of them together and constantly have to switch back and forth by closing the tool. There are no messages in the sql error log, event viewer or windows log.
I believe it may be a problem with the installation of Management Studio because I only get this problem through my remote connections. I don't encounter this error when I access the server through Management Studio from my workstation and open multiple connections.
Has anyone seen this or can someone offer me some direction as to where to look?
Hi, I have created a DSN from the ODBC(Windows Control Panel) in Administrative tools. Is there a way I can connect to that DB from my Microsoft SQL Server Management Studio? PS:The Provider for this DB does not exist in LinkedServer
I am using a Foreach loop container to go thru all the files downloaded from the ftp site and I am assigning the file name of each file to a variable at the foreach loop level called filename. In the dataflow task inside the foreach loop container, I have a source script component that uses a flat file connection. The connection string of the flat file connection is set to the filename variable declared at the foreach loop level. However the script component has a error System.ArgumentException: Empty pathname is not legal.
Please let me know how to correct this? The connectionString property of the flat file connection is set to the complete filename including the path. Does a script component need to have a flat file name specified in the flat file connection that it is using? I need to have a script source component as the flat file I am reading from is not in any of the standard formats.
The flat file connection manager's connection string property is blanked out the moment I specify an Expression for the connection string. Is this a defect or is it expected behavior.

I had SQl Express version installed previously and everything worked. I could connect to one server running SQL Express and a different server running full up SQL 2005 enterprise version.
I uninstalled All SQL express programs and installed tools from SQL 2005 developer.
I have rebooted, started the program directly (not using a link of any kind) and all attempts fail. After dismissing the error msg the tool opens and I can run queries agains the DB but the database engines and related tables do not show.
My work station is Windows XP with SP2 installed.
I have googled the problem extensively and tried solutions found but none have solved the problem.
I have installed multiple instances of SSRS on same server with different database. I can go to the report server URL for both SSRS and run reports. But I cannot connect to the 2nd instance through "SQL Server Management Studio". Also I am getting following error when I try to connect to the "Reporting services configuration" tool from a remote machine

In a Data Flow, I have the necessity to use a SSIS variable of type €œObject€? inside Script Component and assign to it the content of 'n' variables of string type. On exiting from the script the variable of type object should contain something like in the following lines: AAAAAAAAAAAAAAAAAAAAAAAAAAAAA BBBBBBBBBBBBBBBBBBBBBBBBBBBBB CCCCCCCCCCCCCCCCCCCCCCCCCCCCC DDDDDDDDDDDDDDDDDDDDDDDDDDDDD €¦€¦€¦€¦€¦€¦€¦. €¦€¦€¦€¦€¦€¦€¦. On exiting from the data flow I will use the variable of type Object in a Script Task, by reading each element in a cyclic fashion. Is there anyone who have experienced something like this? Could anyone provide any example of that? Thanks in advance!
