Foreach Loop Container Foreach File Enumerator Sort Files

How do you sort files from the Foreach loop container?
I love this component, except I can't get it to sort by filename.
Nice to know how to sort by timestamps also.

Reading More Than 1 Set Of Files Using Foreach Loop Container
Jun 17, 2006Hi,
My requirement is I have to read 2 sets of files from a folder. For example, I have to read all files starting with either 'a' or 'b' only. In 'Foreach Loop', if I say 'a*,b*', it is not working. Instead of comma (,), I tried colon, semi-colon and pipeline characters also. It is not working. So I am using 2 loops now. But I would like to know is there any way to do it using a single loop?
Thanks.
Files Not Found In Foreach Loop Container
Jan 8, 2008
In all of our extract packages, we use a foreach loop container to grab files from the 400 sitting out in a certain directory. For this particular package, we have specified the files should be named RP*.* We know there are several files out in the directory. The package runs without error and completes, but says no files were found in the directory with that name. What could be causing this issue? Thanks!
Integration Services :: ForEach Loop Container Finds No Files But There Are Some
Sep 17, 2015I use a ForEach Loop Container in a ssis Package. The package has to look up in the directory 'f:ackups' for backupfiles and copy them into another folder.In my development environment it works fine. But if I run it on the SQL-Server with the SQL-Server Agent, the package logs always that the folder ist empty.Unfortunately the message is always 'empty folder' even if I define 'f:labla' as folder that actually not exists!
As filespecification I tried both *.* and *.bak .My assumption is, that the SQL-Server agent has not enough rights for that folder. But on the other side the agent is able to create backup-files in this folder.The SQL-Server Agent works under netservice control.

For Loop Container To Process All Excel Files
Oct 5, 2005I'm having a problem getting the for loop container to process all excel files in a folder. I set the collection folder to where my .xls files are, and i set a variable in the for loop container to the FileName. I then changed my source connection and added expressions for

Jun 30, 2006What I'm trying to achieve is a SSIS package that will pick up 1 or
more excel files, process the data in them via the conditional
splitter, pushing the good data into a table, and all other rows into
an error table.
I'm having some issues using the ForEach container to process multiple
excel spreadsheets into tables. The excel import into the tables is
more or less working (imports data for good cases, but uses a null if
the Excel Source when it gets an unexpected value - but that's a
seperate problem).
I found something related to this when searching, but it related to
CTPs (June and September) and trying to reuse the connection strings
they built up there (using my own variable names, naturally) causes a
'Property Value failure':
--------------------------------------------------------------------------------
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.

I attemtpted to use this:
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" +
@[User::RankingFileFullPath] + ";Extended Properties="Excel
8.0;HDR=YES";"
The excel importer works fine as a stand-alone component. Trying to use
the process defined in 'Profession SQL Server Integration Services'
pp140, I tried to use an expression to assign the variable value to the
connection string. I get a validation error:

Any advice?

I attempted to change the package - I set the Data Flow validation to
Delay Validation, and changed the expression to change from:

to
ExcelFilePath @[User::RankingFileFullPath]

Foreach Loop Container - Foreach ADO Enumerator How Performance Compares To Use Of Cursors In Stored Procs
Apr 22, 2008
Hello
I have a question
How is foreach loop container - foreach ADO enumerator performace in SSIS package compares to use of cursors in stored procedures
Is there any articles comparing them
I understand a lot of factors can affect the performance, however what is expected performance for the foreach ADO enumerator loop for large dataset. What is Microsoft recommendation for that - recommended - not recommended (using large datasets - over million records)
Thank you

Foreach Loop Over Excel Files Seems 'fragile'
May 24, 2007All,
I have a package that loops over ~60 Excel files in a directory. Each
file has three named ranges in it, which I import into different
tables. Sometimes the package runs without a hitch, sometimes it
chokes. But it is intermittent.
If I pull the control flow components out of the foreach loop and
point the Excel connection manager to the specific Excel file that has
caused the package to choke, I get a message in the dataflow component
pointing to the named range that "the metadata of the following output
columns does not match the metadata of the external columns......Do
you want to replace the metadata of the output columns with the
metadata of the external columns?" When I choose 'yes', then the
file will be loaded. then I can put the control flow components back
into the foreach loop and the file will run again, successfully, along
with some more, until it chokes again....
So, first of all, does anyone have any insight into this? Sometimes,
somedays, these files will load with no problems. These exact files;
I am having to reload constantly... Other times, like today, it is a
battle.
Otherwise, is there a way to get Integration Svcs to handle the
metadata issue on the fly???
Any ideas, resources, references, war stories, or good clean jokes
would be appreciated,
Kathryn

ForEach Loop Container Question
Nov 6, 2006Hi
Currently the ForEach Loop container is set to loop over the entire collection of records in my table, but I only need to loop thru the records where the status = x. How is that possible? Can I use expressions to set the enumerator to do something like this. Basiclly the collection values are used for further processing, and I would like to avoid looping thru records which have been processed already, which means they already have a status set to y. Please let me know. Thanks.

ForEach Loop Container And First Task

My Foreach Loop container has 10 different task inside. I want to execute the first task only one time. I have a variable with increases for each repition. How can I put precedence contstraint on the first task so that it should execute only first time and other task has to execute all the time.

FOREACH Loop Container: Continue ?
May 26, 2006With a ForEach container, configured to loop through files in a
directory, if I have a problem with a file.. can I direct the loop to
skip on to the next file?
I'm processing structured files, first record of each is some
header info, body records are in the middle, and then the last record
is a trailer containg a checksum
So, for each file in the directory, I split the records into three raw
files, one for header rec(s) , one for body recs and one for trailer
recs. (based on line numbers and using a conditional split to direct
the records)
Then I start by processing the header recs in a dataflow.. if all goes
well there I move on to the next dataflow to process the body recs from
the DataRecs raw file.. etc...
I would like to do some validation at each processing step.. if a
header rec fails validation say... then I'd like to just stop
processing that file and move onto the next file...
Now, I don't see my validation throwing an exception... so its more
that I'd decide (maybe using an Audit ) that the header doesn't pass
validation.. then I'd like to put a record in an error table (with info
about filename, source etc, not just content of the current data row)
But not sure what approach to take on this...
If there is an appropriate section in BOL please point me at it...
Thanks

ForEach Loop Container Issue!!!
Feb 9, 2007Hi everyone,
I am having hard time with foreach loop container. The for each loop container in my package goes over all the rows in a ADO enumerator recordset variable and shows row values one by one in message box. The problem is that it just keeps printing the first row infinitely. Could anyone tell me what could be wrong?
Thanks in Advance,

File Metadata And The Foreach Loop Container
Jan 4, 2007Hello,
I want to set up a Foreach loop container to loop through several flat files. I have a connection manager set up for individual flat files. The metadata for the files is all the same. They are fixed width files, and contain sixty five columns.
I didn't see a place in the container properties to configure the metadata of the files. How can a Foreach Loop Container 'know' the metadata of the flat files that I want to loop through?
Thank you for your help!

Foreach Loop Container Does Not Iterate Automatically
Sep 19, 2007Hi,
Another classic example of something silly I must be doing
I have a "Foreach Loop Container" which uses a "Foreach ADO Enumerator".
The object source is a recordset variable.
Inside the "Foreach Loop Container", a lot of things are happening - some Execute SQL Tasks, Send Mail Tasks, Script Tasks and also a couple of Sequence Containers.
Now, I am getting 2 records in the recordset, but, the "Foreach Loop Container" executes just once.
Any Ideas?
Thanks in advance.

Logging The Foreach Loop Container's Variables
Apr 23, 2008Hello
I would like to loop through a folder and then log the folder's content, as in the names of the files, into a database like all the events get logged. Here is what i have done. I put some files into the folder c: emp made a loop through it, set up a variable 'temp' scope is the foreach loop, set the variable raisechangedevent to true. I have also confgigured the loop to put the result of the looping, in the temp variable in the variable mappings tab.
Strangely nothing is recorded into the "execution results" when i test run the package ? Do i need to make a event handler for the onvariablevaluechanged event for the foreach loop container to be able to get the value of the variable logged or is there something other that i'm missing ?
Using Array Variable In ForEach Loop Container
Mar 1, 2007Dear all,
I have a problem using SSIS since I was a beginner, the problem is I have to do some data transform from flat files into database. These flat files come from many branches of my office with the file structure like this D:SSISranch_nmfile_nm.txt, in folder SSIS there are many branch_nm folder and each branch_nm folder contains many flat files.
My idea was grab the branch_nm folder into array variable using Script Task and then loop this array variable using ForEach Loop Container to get the file and using it for Flat File connection, but I don't know the way to do it.
May this idea work out for sure ?? How to use array variable, that we previously defined inside Script Task, in ForEach Loop Container ?
Thanks in advance
How To Check Out EOF Inside A Foreach Loop Container?
Apr 12, 2007Hi everyone,
I've got a Foreach loop container which uses a Foreach ADO Enumerator and works fine.
But problem comes when I launch inside the general loop another Sql Task (select) which sometimes has rows and sometimes hasn't. When it have rows everything is fine the workflow follows fine but when it has not.
I obtain this error (obvioulsy)
[Execute SQL Task] Error: An error occurred while assigning a value to variable "GZon": "Single Row result set is specified, but no rows were returned.".
How to deal with that?
Thanks indeed
Folder Expression In Foreach Loop Container
Jun 20, 2007I have a Foreach Loop Container task. I am using it to loop through some files in a folder. I tried to use an expression to set the folder to a variable called DataDirectory. I did not see a folder expression.
How can I set the folder at runtime?
Variable Mapping And Index For The Foreach Loop Container.
Jul 25, 2006Hi:
I am trying to loop through 4 files in a folder and read the names of those files through the For each loop container task. I have 4 readme files (readme1.txt thru readme4.txt) in a folder called C:SSIS.
I have added a for each Loop container and a script task to my package. In the Variable Mapping page I have named the Variable and configured the index to be 0. The problem is when I execute the package the file name that is read is always readme1.txt. I want all the file names to be read under the folder ( in other words configure the index to be 0 thru 4). How do I configure the index so that it can read all the files?.
The following is the code I have in my script task:
Public Sub Main()
Dim variables As Variables
If Dts.Variables.Contains("FileName") = True Then
Dts.VariableDispenser.LockOneforRead("FileName", variables)
End if
Msgbox ("Retrieved the File " & CStr(variables("FileName").Value))
Dts.TaskResult=Dts.Results.Success
End Sub
When I execute the package with the above code, I always see a message box popping up and saying Retrived File Readme1.txt.
I want the msgbox to pop up and say
Retrieved Readme1.txt
Retrieved Readme2.txt
Retrieved Readme3.txt and so forth...
Any help on achieving this is appreciated.
Thanks

XML Task Inside Foreach Loop Container Had To Fail!!!
Aug 9, 2007
Hi,
I am using an XML task for validating the XML data against the Schema XSD. I have more XML Files with same the schema. I have to used a for loop container which has an XML task for validate XML. The loop container gets the XML File into variables name "XMLFileName" which the loop current file, in turn, used by XML Task for validation.
XML task is configured in the option "Validate". I have provided the XML Data in variable name "XMLFileName" also get the name from the loop container and XSD file content File Connection. XML Task stored the result in the another variable name "OKFormat". FailOnValidationFail property set to false.
It had the error when I run the package, the error msg as below:
Error: 0xC002F304 at XML Task, XML Task: An error occurred with the following error message: "Data at the root level is invalid. Line 1, position 1.".
Error: 0xC002928F at XML Task, XML Task: Property "New Source" has no source Xml text; Xml Text is either invalid, null or empty string.
Task failed: XML Task
After that, I had to change the source type from Variable to File Connection, and had to test fixed to some xml file it had ok for validate the XML file againt XSD.
I don't know this is the wrong setting or bug of SSIS, anyone can guide me through.

Dynamically Changing Task Name Displayed Within ForEach Loop Container
Oct 27, 2006Does anyone know how to change the task name displayed within a ForEach Loop Container (or of the ForEach Loop Container task itself) based on a variable. I am pretty familiar with setting variable values during task execution and using expressions to alter task properties based on variables. I have tried using an expression to alter the value of the Name property of the ForEach Loop Container but the name of the ForEach Loop Container does not change during execution. Since the color of the various tasks change during execution, I would think that the task names could be changed as well.
Recordset Destination With Foreach Loop Container - Finding Indexes
Mar 3, 2006
I'm curious to know how other people are handling the Recordset Destination in to be processed by a Foreach Loop Container. It seems a little odd to me that you can only map the parameters by knowing the index of the columns of the Recordset, however, the order that you built the recordset destination doesnt stay the same. I've been debugging for a while to find out that after I saved my recordset destination the order of the fields changed. To some order without a clear logic. I'm going to guess it might be the lineage id.
The bigger problem was this was a really large record set with 60 or so columns. To try and debug the problem of finding the indexes, I had added a Multicast tranform and saved the output to an Excel Destination. Of course, the order I setup the Excel file was the order I got the fields. Why would this not be the case with the Recordset Destination?
