Hello,
I would like to modify "Files" attribute of the Foreach Loop of type File
Enumerator. This attribute is used to set the mask (for example *.txt) to
specify which files to include in the selection. I need to be able to change
this mask dynamically depending on package global variable. Is this possible?
Thank you!
Michael
why when I make a change to a foreach loop container in a SSIS package it does not save?
I am trying to change the base file name and if I change it through either the edit or properties windows, the changes does not save. Fore example i change the Files: or File Spec: from oldfile*.txt to newfilename*.txt and when I save and og bak into the edit area to confirm the change, the Files: section shows as "oldfile*.txt.
Does 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.
I have a for each loop(ADO Enumerator) container which executes for each Advertiserid which is coming from database. In for each loop I have to create a new excel file with the advertiser name. So if the loop executes 7 times there should be seven excel spreadsheets with seven advertiser names.
How can i create an excel dynamically in the foreach loop container.
Hi,
I am using For each loop container in my SSIS package which will loop through more than one input file in the input folder.
All the input files in the input folder are picked by one by one. All the input files in the input folder are executed with the same ExecutionInstanceGUID.
Now, my requirement is to get a new ExecutionInstanceGUID during the execution of each input file in the For each loop container. My package only contains the For each loop container with some logic inside that.
Please let me know if any one can help me for the same.
Regards,
Sriram.

I am getting the following error when trying to load multiple excel files using for each loop container in SSIS, I tried to put the quotes in several different ways but still can't get rid of this error. I was able to successfully load single excel file, but when I use the for each loop container that's when I am having problems. Any help is greatly appreciated. Thx.

Here's the set up:
ForEach Loop Container:
Collection: Foreach File Enumerator
Variable Mappings: Variable = User::DailyFile, Index = 0
Execute SQL Taks:
Connection: OLEDB
ResultSet: None
SQLStatement: EXEC spGetFile ?
ParameterMapping: VariableName = USER::DailyFile, Direction = Input, DataType=VARCHAR, Parameter = 0
This works great it iterates through a file and looks at all the files checks to see if they have been loaded into the db table, if not it loads the file.
My spGetFile has RETURN 1 if a file is loaded and RETURN 0 if the file is not loaded.
Now I add a new variable:
Step 1: add to Foreach Loop Container
ForEach Loop Container Name = Return, Scope = ForEachLoop, Data Type= Int32 Value=0
Step 2: Add to Execute SQL Task:
VariableName = User:Return, Direction = ReturnValue, DataType = Long, ParameterName =1
This produces the following error:
~~"Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.~~
I tried with an ADO.Net connection ... works until I add the ReturnValue parameter ...
Any ideas??
Thanks
Can we drag and drop Existing SSIS package into for each loop container ?
View 3 Replies View RelatedI am having a challenge to pass the filename variable from SSIS Foreach Loop Container to SQL store procedure. I have an "Execute SQL Task" inside "Foreach Loop Container" which will receive the input filename parameter passed by the Foreach Loop Container. The store procedure command line is defined as "EXEC sp_mySQLStoreProcedure ?" within the "Execute SQL Task". The Foreach loop container will gather the filenames from File System then put it in the filename variable one by one. I would like to pass the filename variable as the input parameter to the sp_mySQLStoreProcedure in the "Execute SQL Task". How can I connect the variable and the store procedure so that it will process all the input files gathered by the Foreach Loop Container?
View 4 Replies View RelatedIn order to update an Oracle table target from a SQL Server table source I need to use a Foreach Loop Container, so I can loop on the rows of the SQL Server table source. This source table has two columns: the old identifier to update and the new identifier to apply. I must use the value of the old identifier to filter the Oracle rows to update, while the new identifier is the new value to assign to the filtered old identifier.

If i place a loop container inside a sequence container the connectors within the loop container disappear.... is this a bug - will the loop tasks still run in the correct order?? or will they fire off willy nilly??
Hello
I am trying to use Foreach loop container - Foreach File Enumerator
Is there easy way to retrieve enumerator configuration folder from variable - so I can easily move package from server to server?
I would like to have name of the folder we getting files from retrieved from variable by using this control
Thank you in advance

Hello Experts,
Sorry that I open a new thread again but I didn€™t found any good tutorials about foreach loop container. I would like to read every row from one table and do something.
I red something about sql task€¦ Can someone give a little instruction, please?
Kind regards,

Hi
I using data flow task to import from flat file to database but i need to use Foreach Loop Container to import multiple files in specific folder and all will be insert in the same table
tahnks & Regards
What I'm trying to do is take multiple "snapshots" of a membership for many months. I was trying to do this in a For Loop Container in which I added one to the month variable and subtracted one from an iteration variable each loop, unless the month variable = 13...then I would add one to the year variable, set the month variable to 1 and subtract one from the iteration variable. This, I was hoping, would allow me to initialize 24 to the iteration variable, 1 to the month variable and 2004 to the year variable, kick off the package, and get 2 years worth of "snapshots" in seperate files (one for each month). Here is the AssignExpression I thought would work:
@Member_Month == 13 ? @Member_Month = 1 && @Member_Year= @Member_Year + 1 && @Member_Iteration = @Member_Iteration - 1 : @Member_Month = @Member_Month + 1 && @Member_Iteration = @Member_Iteration - 1
The package states that the single "=" should be double, but I don't think that that is what I want to do (I tried doing this just to check, and it didn't like this either). I think that it is having problems with doing multiple things on both sides of the ":". What am I doing wrong?
Thanks,

We have a config table which has columns like pollingfolder, cop to folder etc.
Data looks like this
Config id polling folder
1 d:dataloadacn
2 d:dataloadship
under ACN and Ship folders we can have more than 1 source files which had to be loaded into target
the load process has to be repeated for each file in all the folders like ACN and ship
I have used for each loop container to poll the folder.
Can we set the directory to be polled at runtime taking from config table.
For doing this I have used the property Directory in expression editor of for each loop. But it is not working.
If I hard code the variable value in variables section , then its working.
How to change the directory to be polled value at runtime?
I'm trying to set up a For Loop Container that steps through the loop based on date logic.
Here's an example of what I'd like to do:
InitExpression | @SomeDate = 1/1/2007
EvalExpression | @SomeDate < GETDATE()
AssignExpression | @SomeDate = DATEADD(DAY, 1, @SomeDate)
The above syntax does not work, and I can't find an example that uses date logic with the For Loop Container.
Can anyone help me with this, or point me to an example that uses the For Loop Container with dats?
Thanks in advance for the help!
Hi,
A very strange thing happened to me. I have a package that includes two For each loop containers. Each container has script tasks, sequence containers, etc. Both are Foreach ADO Enumerator basis. It works without any problems until I changed the position of one of them in the Control flow and added some code in the script task. After these changes I executed the package and both of For each loop containers did not execute the tasks inside of them, any task. However the execution color on the containers was green (success). How can it be?
Your help is much welcome. Thanks in Advance.

Hi
Can anyone point me to an example of using a ForEach Loop Container to step through the rows in a recordset. I cannot seem to see how this is done from the help files.
Thanks
Hi,
I am having problem when setting for-each container's EvalExpression as a variable comparison.
I have set this in expression editor
@[User::Syn] == 1
Editor says that it couldnt convert from System.Bool to System.String.
If I put it in quote, then for-each container says that it needs Bool, not String.
Please help me with this,
Thanks
Hi
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.

I am trying to move files from one directory to anonther using the For Each Loop Container and a File System Task. However, on the FIRST iteration of the ForEach Loop the variable that I am setting to the 0 index of the For Each Loop is returning me a valid directory with no file ( path only ) from who knows where ????
On the second iteration of the For Each Loop everything works as expected and I get the full path and file name and it iterates through all the files in the directory o.k.
So I have had to put a Hack to skip the fist iteration of the loop and then execute the File Task on the second iteration but I dont see anyone else doing this.
Where in the heck is it getting this odd directory from on the fist iteration ( its not my User varible because I am initializing it to \nowhereofile ). What am I doing wrong?
hi everyone,
I've created a Send Mail task which works properly and now I'd like to send that email n times.
How do I such thing. I moved that task inside Foreach loop container and then I choosen "Foreach From Variable Enumerator" and then I've created a Int32 variable.
And now, I don't know how to tell that increments that variable
TIA,
Hi. I am running a package using 'execute package' inside a for each loop file iteration. I have to iterate through some 10,000s of files to ETL source data, a resonably complex package. I want to set going and get some sleep but every 200 files or so I get a memory exhausted error and the task fails. Is there a short easy fix to refresh memory each iteration. If so please let me know. Just ignoring the failure at task level won't refresh the memory, will it?
Thanks for the help.
Hi,
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.
Thanks
Hi All,
Seems like a simple task, but been a struggle.
Simply trying to move a group of files from one folder to another folder and renaming the files with the monthyear in the middle of the filename..
I'm using a FOR Loop container and works find. The added complexity is I'm trying to rename the files the same tine and putting the Month Year into the file name.
I guess the struggle is how to get the file name out so I can manipulate it.
I tried creating variable(V_SOURCE) which stores the file path and create another variable(V_FILENAME) to hold the filename. I believe on the expression page of the FOR LOOP editor if I select the the file name and extension radio button, it should put the file name in the V_FILENAME variable.
In my file task trying to join the two variables together in another variable, keep saying my path is wrong with the file task kicks off.
here's the syntaxt
@[User::V_SourcePath] + @[User::V_FILE_NAME]
With 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

Hi,
I have a "Data Flow Task" inside" For Each container". Data flow task is processing file and updating the DB.
If one of the file is correpted i want to move to error folder and continue with the next file. i have given red arrow to a script Task which move the file to error folder. but its not continuing with next file. how can Ido that?
Any help
Hi 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,
Hi
I am using a foreach loop container and Data flow task dropped on it.
According to the logic the dataflow task should be executed twice and for eacl loop fetches 2 records in the variable used in the sql in Data flow task. It works fine except that it does not iterate twice.It simply executes once.
Please help
Hi,
I am using a For Loop container with a script inside it in My SSIS package. Inside the script I am type casting one of the object variables in a class object of XMLReader Type. I am using CType Function for it. The For Loop is resulting in a memory leak and the references are not getting deleted even if they go out of scope.
Does anyone have faced similar issue?
Please guide.
Thanks.
