SSIS ForEachLoop Error
I am trying to load multiple excel files with multiple sheets but after deploy into server only i am getting this error.
The GetEnumerator method of the ForEach Enumerator has failed with error 0x80131509 "(null)". This occurs when the ForEach Enumerator cannot enumerate.
i also changed in the properties Run64BitRuntime = false. anyone can suggest me what to do for this error?
FOReach loop container
This error gets thrown when trying to enumerate NULL.
It looks like, once deployed, your SSIS package is not finding any excel files, and returning NULL, instead of an empty list.

I'd suggest to put some logging in your package Before the enumeration to see if anything is found, then redeploy it, run and check your logs.

I have a couple of SSIS packages that are using Excel Connection Manager with variables for the path to the file that it will import in a Foreach loop to get all files in a directory. I am getting a couple of errors but I can still run the package from inside of Visual Studio.
Severity Code Description Project File Line
Error Validation error. Data Flow Task: Package: The connection string format is not valid. It must consist of one or more components of the form X=Y, separated by semicolons. This error occurs when a connection string with zero components is set on database connection manager. Package.dtsx 0
Severity Code Description Project File Line
Error Validation error. Data Flow Task: SPackage: The result of the expression "#[User::FilePath] " on property "\Package.Connections[Excel Connection Manager].Properties[ConnectionString]" cannot be written to the property. The expression was evaluated, but cannot be set on the property. Package.dtsx 0
So it appears that the variables are being replaced with the filepath and name but since it gives me these errors I can't deploy it to my SQL Server.
I have DelayValidation = True on all tasks and containers.
How do I either get rid of the error or force VS to deploy it anyway?
Thanks in advance for you help!

Edit:
I am getting the following error when I try and run my package. I am new to ssis. Any suggestions. Tahnks

VS_NEEDSNEWMETADATA shows up when the underlying data behind one of the tasks changes. The fastest solution will probably be to just delete and re-create each element which is throwing an error.
How about disabling validation checks?
Like if you right click on source or destination component and select properties then you will have the property named validateExternalMetadata put that as false and try.
This Solution is working for me.
This normally occurs if there has been a change to your schema, not to stress, just double click on your input and output and it should resolve itself
Make sure your connection is valid. If you are using dynamic connections, then try to set the option "delay validation" = true on the package or dataflow.
In my case destination table structure was not matching with matadata in OLEDB component. I added the missing column which i forgot to add and after that it was fixed.
After researching a bit (check to extract your own conclusions: this and this one), I think I've found a nice workaround for when the problem with the metadata comes from a Ole DB object, but only for a very specific case.
The thing is that when you change your columns names / remove columns / add columns, you can't do anything but update the metadata.
However, if you use a SQL query to retrieve the data from the object, in the case that you don't need to update the query itself, you won't need to update the metadata if the query still can ask for what it wants. Basically, if the query is still valid.
I've tried it within my own ETL, and changed an Ole DB object which was reading the data from an Excel file, targeting one sheet and then I had all the columns selected in the tab.
Changing it for an SQL query to retrieve the full sheet like:
SELECT * FROM ['Sheet_Name$']
Solved completely the case for me, even introducing files with different metadata in headers.
When trying to run a task to copy a file, I'm getting this message:

What am I doing wrong?
Should I completely eliminate this File System Task and replace it with a C# Script Task to copy the file?
Is there something obviously wrong with my process?

the properties page is asking for a variable name and you are providing a file path. Do you have a variable in your SSIS package that can hold the fully qualified file name?
Your SourceVariable property (in screenshot #2) should refer to your a variable name, not the actual value of the variable.
I have an issue with a very simple task in SSIS 2012.
I have a for-each container that runs in FOR-EACH-FILE Enumerator mode. I want to read a target folder with XML files. The path to the folder is correctly configured. The files field is set to *.xml
The variable mapping is defined with the follwing Variable: User::FileVar , Index 0.
Now I add a simple data flow task inside the container. The dataflow task only has a XML-Data Source task, that's it. For the XML Data source task, the XSD location is set. When I click choose columns, I can see the columns from the XSD schema.
BUT: When I save the XML task , I always get the error message: The Property XMLDataVariable is empty. I tried both data Access modes, XML file from variable and XML data from variable. The error message remains, I cannot run the package.
I don't use any expressions, neither at the foreach loop container nor at the data flow task.
I dont know what's wrong here, I did the steps exactly as shown in some tutorials for older versions of SSIS.
Do you have any ideas?
The issue is that the XML Source is trying to validate the existence of the given file during the design time. However, you will know the file name only during runtime when the Foreach loop container executes and loops through every XML file available in a given folder.
I recreated an SSIS 2012 package using my answer to one of other SO questions.
SSIS reading multiple xml files from folder
I was able to reproduce the error The property "XMLDataVariable" on the XML Source was empty
On the XML source, I set the property ValidateExternalMetadata to False. Setting this to false will force the package not to verify the existence of the xml file path during design time.
I was successfully able to execute the package.
Hope that helps.
I'm currently working on an SSIS package to load mainframe logs from multiple server/file sources into a database.
As it stands at the moment I'm using a foreach loop container to loop through a recordset containing filenames and load the files using a Data Flow task from a Flat File Source and File connection to an OLE DB Destination through a Derived column.
I've built in error handling on the Data Flow task to allow for the fact that there won't always be a log file in the location specified (ie. because the server was down for maintenance during a specific period as the files are generated on an hourly basis), but the problems start after it finishes handling these errors.
If the file immediately following an attempt to load a file that wasn't found exists it begins to load it but then throws the following warning message: [Message Log File Source (NORDXSL) [57]] Warning: There is a partial row at the end of the file., and doesn't load all of the records in that file.
However, when I remove the files I know won't exist from the recordset (so that it only attempts to load files that do exist, including the one with the alleged "partial row"), everything works fine and all files/rows are loaded without a problem. It just seems to not want to load the first file after it's failed a missing file correctly and I can't for the life of me work out why?
I've tried calling Dispose() and ReleaseConnection() on the file connection after the Data Flow task has finished processing but this makes no difference and I'm now completely out of ideas.
Any help would be really appreciated as this is the last bug in this project and I want to get it out the door. PLEASE!!
Thanks,
James
I've now found a workaround for this problem...
I've added a Script Task before the Data Flow Task to load the files that checks to see if the file I want to read exists:
If (System.IO.File.Exists(Dts.Variables("MQLogMessagePath").Value.ToString)) Then
Dts.TaskResult = Dts.Results.Success
Else
Dts.TaskResult = Dts.Results.Failure
End If
If it doesn't exist it fails the iteration of the Foreach Loop container and continues onto the next file.
BINGO!
