I have an Execute SQL Task that reads columns as strings but can be null. I feed the information in the result set to a foreach loop container and when nulls are encountered the package dies there. Is there an easy way to deal with this other. I have changed all of my null possible columns to object types but I don't want to do this for all of the possible null columns.
Thanks
Hi ALL,
Getting Access Denied To FileName Error When Using the Execute Sql Task (With File Connection) into a Foreach Loop Container.
Please Note :
I have a folder containing .sql files. I have to dynamically loop through the files and send them as a File connection Folder to the Execute Sql Task.
When I run this Package I am getting the follwoing error :
[Execute SQL Task] Error: An error occurred with the following error message: "Access to the path 'C:ProjectsFuzzy Lookup DataFlow ExampleScripts' is denied.".
Also I have logged in to the machine as Administrator and to Sql Server with sa.
Please help.
Thanks.

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,
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.
Hi everyone,
do you know any articles on foreach loop container that loops over a dataflow task...pls tell me....
thanks in advance,
OK. I give up and need help. Hopefully it's something minor ...
I have a dataflow which returns email addresses to a recordset.
I pass this recordset into a ForEachLoop configuring the enumerator as (Foreach ADO Enumerator). I also map the email address as a variable with index 0.
I then have a Execute SQL task which receives this email address as a varchar variable (parameter 0) which I then use in my SQL command to limit the rows returned. I have commented out the where clause and returned all rows regardless of email address to try to troubleshoot this problem. In either event, I then use a resultset to store the query result of type object and result name 0.
I then pass this resultset into a script variable to start parsing the sql rows returned as type object. ( I assume this is the correct way to do this from other prior posts ...).
The script appears to throw an exception at the following line. I assume it's because I'm either not passing in the values properly or the query doesn't return anything. However, I am certain the query works as it executes just fine at the command prompt.
Try
ds = CType(Dts.Variables("VP_EMAIL_RESULTS_RS").Value, DataSet)
My intent is to email the query results to each email address with the following type of data by passing the parsed data from the script to a send mail task. Email works fine and sends out messages but the content is empty. I pass the parsed data as string values to the messagesource and define the messagesourcetype as a variable in the mail task.
part number leadtime
x 5
y 9
....
Does anyone have any idea what I might be doing wrong?
thanks

I am looping through xml files and validating them with the XML Task. On sucess I want to perform task 2, on failure I want to perform task 3. When one file fails to validate all subsequent tasks fail.
I have also tried putting the result in a variable instead of using the success constraint. I get the same result, the variable keeps the failed value after the first file fails. Any advise is greatly appreciated.
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.
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.

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

Hello All
I was trying to insert some row from one table to another of different database.
I was using Execute SQL task along with Foreach loop container.
In my execute SQL task I am using this query
SET IDENTITY_INSERT dbo.Table1 ON
INSERT INTO dbo.Table1
SELECT * FROM DB2.dbo.Table2
WHERE TableKey = ?
When executed I get this error:
failed with the following error: "Syntax error, permission violation, or other nonspecific error". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
While the same query when executed in Management Studio Its successful.
The properties I set
For Each Loop Editor Settings:
1) Collection: a) Enumerator Set to ForEach ADO Enumerator
b) ADO Object Source Variable: User:bjectVariablename
c) Checked Rows in the first table
2) Variable Mapping: New Int Variable2 and Index = 0 to set it to first colunm.
3) Expression: Left blank

Hi all,
I'm trying to capture the file name and insert to the Database with Loop Container and Execute Sql task...However when I run, I get error with the input parameter.
In my Sql Task, the parameter mapping:
Variable name: user::variable,
direction: input,
Data Type: Varchar,
parameter name: @xVariable,
parameter size: -1
connectiontype: OleDB
sourcetype: direct input
statement : insert into xtable(xcolumn) values(@xVariable)
Anyone have any other suggestion how to capture the filename and input in the database?
thanks
Hi,
I am trying to use SSIS.Execute Process Task within Foreach loop . The task should unzip a a variable gzip file provided to it from the previous task
to execute the command from cmd C:Program FilesGnuWin32ingzip.exe -d -k c:folderfilename
My input in the Execute Process Task as follow:
The command line: C:Program FilesGnuWin32ingzip.exe
Argument: -d -k c:folder
Variable: User::var_filename
keep getting error
The process exit code was "1" while the expected was "0".
Thanks
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
Hi:
I am a R data miner who is new to SQL and SSIS and would appreciate any help.
I wanted to automate the process of creating and processing decision tree models for every county in the Country. I wanted to use the foreach loop for iterate through all the counties. I wanted the foreach enumerator to be used by the XMLA code that creates the model so it would append it to the name of the model and i would get a different model for every county. I am not sure how to have the XMLA code accept foreach loop enumerator.
Any help would be greatly appreciated and if you could direct me to a previously done example that would greatly benefit me.
Thank you

hi
I am trying to execute a UDF in an Execute SQL Task within a Foreach loop.
I have an Execute SQL task to get the dataset (Firstname, Lastname, CompanyID) which is going into a full result set called @PendingPar. The Foreach Loop is set to a Foreach ADO Enumerator against @PendingPar and I have created 3 variables at the Foreach Loop scope level called @Firstname (String), @Lastname (String) and @CompanyID (Int32). These are mapped in the Foreach Loop as index 0,1 and 2.
Within the Foreach Loop I have an Execute SQL Task with the sql command
select dbo.udf_GetParTitle (?,?,?)
In the parameter mapping I have Variable Name = User::Firstname Direction = Input Data Type = VARCHAR and Parameter Name = 0, User::Lastname, Input, VARCHAR, 1 and User::CompanyID, Input, VARCHAR,2
Finally the UDF returns a @NewPar value so i have the result set in the execute sql task to Single Row which goes into variable @NewPar. This @newPar will be used later but I cannot get the first bit to work yet.
the error message i get back is
Error: 0xC002F210 at Execute SQL Task 1, Execute SQL Task: Executing the query "select dbo.udf_GetParTitle (?,?,?)
" failed with the following error: "Syntax error, permission violation, or other nonspecific error". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
Task failed: Execute SQL Task 1
the initial execute sql task where the dataset is selected works fine but it is within the foreach loop that it fails.
any help gratefully recieved
SSIS Newbie Question:
I have a simple Control Flow setup that checks to see if a particular table exists. If the table does not exists, the table is created in an alternate path, if it does exist, the table is truncated before moving to a file import Data Flow that uses an OLE DB Destination to output the imported data.
My problem is, that I get OLE DB package errors if the table the OLE DB Destination Container references does not exist when I load the package.
How can I over come this issue? I need to be able to dynamically create the table in an earlier step, then use that table to import data into in a later step in the workflow.
Is there a switch I can use to turn off checking in the OLE DB Destination Container so that it will allow me to hook up the table creation step?
Seems like this would be a common task...
Steps:
1. Execute SQL Task to see if the required table exists
2. Use expresions to test a variable to check the results of step 1
3. If table exists, truncate the table and reload it from file in Data Flow using OLE DB Destination
4. If table does not exist, 1st create it, then follow the normal Data Flow
Can someone help me with this?
Signed: Clueless with a deadline approaching...
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
Is there a way to set a variable as a substring of the enumerator in a Foreach File Enumerator type? The Variable Mappings tab in the Foreach Loop Editor does not allow you to enter an expression.

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
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.
MA
Could someone send me any links or information on how to loop through an ADO.NET dataset in SSIS? I need step by step information please.
Thank you,

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 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,
I have a few hundred data files that I need to process in groups from oldest to most recent. To that end, I have created staging folders for each date that appears in the file names (example: 20060213) and moved all of the data files to the appropriate folders.
I also have these folder names in a recordset that has been sorted in ascending order, so the oldest date should be the first record, the second-oldest date should be second and so on. My thinking is to use this recordset with a ForEach Loop Container to loop through each folder, but I am not sure if Integration Services will necessarily loop through the records in order.
Can someone tell me whether the records will be processed in order or suggest a better alternative to make sure the directories are processed in the correct order?
Dear All!
I have a "Foreach Loop Container" to search files in a folder. And I only want to search .txt and .txt.gz file. I set property "FileSpec" as "*.txt,*.txt.gz" but my container dont run. Can you help me?
Thanks
Hello,
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!

Hi,
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.

Hello
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 ?
Dear 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
Hi 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
Hi,
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.
