Get index in foreach loop

Hi,
I have to iterate a list and get a value from another list. Something like this:
for (String element: A)
x.replaceAll(element, B.get(A.indexOf(element)));
}Is there a another way to get the index we are at?

So...the code you have provided iterates though the
whole collection aswell. It's not better in any way.
And it may be even slower (depending on the
implementing class) as it has to call a.get(i) to
retrieve the object. I like the style of the new for
better. Where's the problem????It might be slower on a LinkedList (or any other List that doesn't implement RandomAccessList), but in general it will be much faster, because in your code you called .indexOf() which is an expensive operation in allmost all List implementations (I can't think of a default implementation where it's fast right now).

Issue with get-wmiobject and foreach loop

I'm trying to run a get-wmi win32_operatingsystem command and when i pipe in a few computers to the $comp variable everything works fine. When i run this against all the computers in AD i get no results back in my .csv
im stumped as too why... any thoughts ?
$comp = (Get-ADComputer -filter * | where {$_.Enabled -eq 'True' } | select name)
foreach ($computers in $comp) {
Get-WmiObject -Class win32_operatingsystem -Property * -ComputerName $computers | select PSComputername,OSArchitecture, Name | Export-Csv C:\Get-OsVersionAllComputers.csv -Append -NoTypeInformation

If you are just typing commnds like this to get quick infor this can be compacted very easily and test a piece at a time:
# step 1
Get-ADComputer -filter 'Enabled -eq $true'
#now add wmi
Get-ADComputer -filter 'Enabled -eq $true'|%{gwmi win32_operatingsystem -cn $_.Name }
# add the select
Get-ADComputer -filter 'Enabled -eq $true'|%{gwmi win32_operatingsystem -cn $_.Name } |
    Select PSComputername,OSArchitecture, Name
# add the export.
Get-ADComputer -filter 'Enabled -eq $true'|%{gwmi win32_operatingsystem -cn $_.Name } |
    Select PSComputername,OSArchitecture, Name |
    Export-Csv C:\Get-OsVersionAllComputers.csv -NoType
Using this approach PowerSHellmakes building complex commands very easy. JUst start thinking in declaritive termms in the pipeline.

How can I load a .xlsx File into a SQL Server Table using a Foreach Loop Container in SSIS?

I know I've REALLY struggled with this before. I just don't understand why this has to be soooooo difficult.
I can very easily do a straight Data Pump of a .xlsX File into a SQL Server Table using a normal Excel Connection and a normal Excel Source...simply converting Unicode to DT_STR and then using an OLE DB Destination of the SQL Server Table.
If I want to make the SSIS Package a little more flexible by allowing multiple .xlsX spreadsheets to be pumped in by using a Foreach Loop Container, the whole SSIS Package seems to go to hell in a hand basket. I simply do the following...
Put the Data Flow Task within the Foreach Loop Container
Add the Variable Mapping Variable User::FilePath that I defined as a Variable and a string within the FOreach Loop Container
I change the Excel Connection and its Expression to be ExcelFilePath ==> @[User::FilePath]
I then try and change the Excel Source and its Data Access Mode to Table Name or view name variable and provide the Variable Name User::FilePath
And that's when I run into trouble...
Exception from HRESULT: 0xC02020E8
Error at Data Flow Task [Excel Source [56]]:SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occured. Error code: 0x80004005.
Error at Data Flow Task [Excel Source [56]]: Opening a rowset for "...(the EXACT Path and .xlsx File Name)...". Check that the object exists in the database. (And I know it's there!!!)
I don't understand by adding a Foreach Loop Container to try and make this as efficient as possible has caused such an error unless I'm overlooking something. I have even tried delaying my validations and that doesn't seem to help.
I have looked hard in Google and even YouTube to try and find a solution for this but for the life of me I cannot seem to find anything on pumping a .xlsX file into SQL Server using a Foreach Loop Container.
Can ANYONE please help me out here? I'm at the end of my rope trying to get this to work. I think the last time I was in this quandry, trying to pump a .xlsX File into a SQL Server Table using a Foreach Loop Container in SSIS, I actually wrote a C# Script
to write the contents of the .xlsX File into a .csv File and then Actually used the .csv File to pump the data into a SQL Server Table.
Thanks for your review and am hoping and praying for a reply and solution.

Hi ITBobbyP,
If I understand correctly, you want to load data from multiple sheets in an .xlsx file into a SQL Server table.
If in this scenario, please refer to the following tips:
The Foreach Loop container should be configured as shown below:
Enumerator: Foreach ADO.NET Schema Rowset Enumerator
Connection String: The OLE DB Connection String for the excel file.
Schema: Tables.
In the Variable Mapping, map the variable to Sheet_Name, and change the Index from 0 to 2.
The connection string for Excel Connection Manager is the original one, we needn’t make any change.
Change Table Name or View name to the variable Sheet_Name.

Foreach Loop only looping once

Hi,
Please be patient and bear with me, for I am new to SSIS packages.
I am using SQL Server 2008 R2 to host the SQL Agent job and the SSIS package.
I am using Visual Studio 2008 Professional Edition for designing the SSIS package. It is version 9.0.30729, Version 3.5 SP1.
I am on a Windows 8 machine.
My Foreach Loop Container seems to iterate only once when it should iterate numerous times, and this issue happens BOTH when I execute the SSIS package from within Visual Studio AND when I run a SQL Agent job to execute the SSIS package.
For the solution within Visual Studio, I have False for the property Run64BitRuntime.
In the SSIS pckg in Visual Studio, I have in the Variables pane a number of variables and these following variables pertain to my problem:
Name: objRs     Scope: the name of the SSIS package     DataType: Object    Value: System.Object
Name: txtVendorFamilyNumber   Scope: the name of the SSIS package DataType: String   Value: 111111
The value "111111" that I entered into the txtVendorFamilyNumber variable in the Variable Pane is NOT a realistic value as there are no vendor family numbers that have the value 111111. I will populate dynamically the real vendor family numbers
from within the SSIS package.
When I imported the SSIS package to SQL Server 2008 R2, via the ellipsis button for the Protection Level I chose the "Rely on server storage and roles for access control" choice.
Concerning the flow of the SSIS package, going down within Visual Studio from the beginning of the flow of the SSIS package, eventually I have an Execute SQL Task. In its General tab, it has "1252" for CodePage property, "Full result set"
for ResultSet property, "OLE DB" for ConnectionType property, "Direct input" for SQL Source Type property, "False" for BypassPrepare property, and the following for the SQLStatement property:
     select txtVendorFamilyNumber from tmpVendorFamily where VendorID = (select min(VendorID) from tmpVendorFamily)
In the tmpVendorFamily table on SQL Server 2008 R2, there are 379 rows of results for the SELECT statement above (starting with the values 100110, 100115, 100120, 100130, through the LAST row's value 106370.
In the Parameter Mapping tab of the Execute SQL Task Editor, I have nothing. In the Expressions tab of the Execute SQL Task Editor, I have nothing.
In the Result Set tab of the Execute SQL Task Editor, I have the value 0 for Result Name property and I have the value User::objRs as the value in the Variable Name property.
This Execute SQL Task has a green arrow (Constraint evaluation operation, Success in Value drop down) to the Foreach Loop Container.
In the Foreach Loop Editor, in the Collection tab, I have "Foreach ADO Enumerator" as the value in the Enumerator property. In the drop down for ADO Object Source Variable, I have chosen the User::objRs, and I have the radio button "Rows in
the first table" selected.
In the Foreach Loop Editor, in the Expressions tab, I have nothing.
In the Foreach Loop Editor, in the Variable Mappings tab, I have "User::txtVendorFamilyNumber" for the Variable property and I have the value "0" for the Index property.
So in the Foreach Loop, I first have a Script Task with the ReadOnly variable User::txtVendorFamilyNumber and with the ReadWrite variable User::TESTING_OnlyTesting that I created with a package scope, string datatype, and no default value. This Script Task
has the following code for testing purposes:
Dim strFullVerbiage As String
strFullVerbiage = "The value is: "
Dts.Variables("User::TESTING_OnlyTesting").Value = strFullVerbiage + Dts.Variables("User::txtVendorFamilyNumber").Value.ToString()
Dts.TaskResult = ScriptResults.Success
I have next in the Foreach Loop Container a Send Mail task. In the Expressions tab of the Send Mail Task Editor, I have for the Message Source property the following:
      @[User::TESTING_OnlyTesting]
The remaining tasks (including FTP Tasks) in the Foreach Loop Container are disabled for now as I am trying to figure out why the Foreach Loop only iterates the FIRST time, only iterates once.
When I run on SQL Server 2008 R2 the SELECT statement from the Execute SQL Task, I get 379 rows of results. The default value 111111 that I entered into the Variable Pane for the txtVendorFamilyNumber variable does NOT exist in any of these 379 rows of results.
The 1st row of results has for the txtVendorFamilyNumber column the value 100110. Then the subsequent rows of results have the values 100115, 100120, 100130, et cetera, ending with the value 106370 in the last row of results.
I imported the SSIS package into Integration Services on SQL Server 2008 R2. When I imported to Integration Services, in the Import Package editor for the Protection Level I chose the "Rely on server storage and roles for access control" choice
because there are FTP Tasks and we needed to use this "Rely on server storage and roles for access control" choice.
I created a SQL Agent job that executes this SSIS package.
When I run the SQL Agent job, no error happens and I get only ONE email with the value 100110 for the vendor family number in it. I should get 379 emails total, the 2nd email showing 100115, the 3rd email showing 100120, et cetera.
When I was testing while executing the SSIS package from within Visual Studio, I did NOT have the Send Mail task and I only had enabled one Script Task that had the ReadOnly variable User::txtVendorFamilyNumber and the following lines of code:
MsgBox(CType(Dts.Variables("User::txtVendorFamilyNumber").Value, String))
Dts.TaskResult = ScriptResults.Success
Executing the SSIS package with only this Script Task enabled within the Foreach Loop Container, I would get the ONE message box showing 100110 but I would not get any message box for a SECOND ITERATION of the loop.
Since my txtVendorFamilyNumber in the Variables Pane has the default hard-coded value 111111 that does NOT exist in the result set of the Execute SQL Task that feeds the Foreach Loop, and since the first and only email sent shows the value 100110 when I
run the SQL Agent job that runs the SSIS package that is set up to send an email from within the Foreach Loop Container, the FIRST LOOP seems to run correctly and shows correctly the 1st value 100110 in the 379 rows of results that populate the Foreach Loop
Container. Why does the Foreach Loop Container NOT loop more than once?
Could anybody give me any suggestions as to what the problem might be?
I thank you in advance for your consideration of my problem. I have been reading and reading on the Internet to try to find a solution but I have not solved yet my problem with the Foreach loop only iterating once.
Thanks much to you.

Gregarious greetings Arthur,
I very much appreciate your reply.
This morning I figured out my problem with the help of a fellow employee.
In my original post higher up, I had typed about the SELECT statement in the Execute SQL Task that is just before the Foreach Loop Container and that populates the User::objRs, and this SELECT statement was in the old DTS package in an old ActiveX script
task. The SELECT statement was in an old DTS package in an old ActiveX script task and I am creating a new SSIS package to replace the old DTS package so that we can move from the old version of SQL Server to a new SQL Server 2008 R2 server. Here is that
SELECT statement:
select txtVendorFamilyNumber from tmpVendorFamily where VendorID = (select min(VendorID) from tmpVendorFamily)
That SELECT statement above returns ONLY ONE result. I had not noticed it. That SELECT statement fills the objRs result set. The green arrow goes from the Execute SQL Task that has the SELECT statement down to the Foreach Loop Container that loops over the
result set. Since the SELECT statement that fills the result set only has one row of results, the Foreach Loop only looped once.
So for the Execute SQL Task that populates the result set User::objRs, I changed the SELECT statement to be the following:
--In the Utilities DB, this tmpVendorFamily table
--has only two columns named VendorID and txtVendorFamilyNumber.
SELECT DISTINCT txtVendorFamilyNumber
FROM Utilities.dbo.tmpVendorFamily
ORDER BY txtVendorFamilyNumber
Now the Foreach Loop will loop 379 times since the SELECT statement immediately above yields 379 rows of results.
So the Foreach Loop Container was fine. Its Collection tab has the "Foreach ADO Enumerator" for the Enumerator and has the "User::objRs" for the ADO Object Source Variable. Its Variable Mappings tab has "User::txtVendorFamilyNumber"
for the Variable and has "0" for the Index.
My problem was the SELECT statement in the Execute SQL Task that immediately precedes the Foreach Loop Container and that fills the User::objRs result set. The SELECT statement yielded only ONE row of results. When I corrected this morning that SELECT statement
so that it correctly yields 379 rows of results, the Foreach Loop Container loops 379 rows.
Thanks again for replying and trying to help. I very much appreciate it.
I consider this thread that I created to be closed since I figured out this morning how I needed to correct the SELECT statement in the Execute SQL Task that fills the result set on which the Foreach Loop loops.

Urgent---- Usinging t-sql in Foreach loop with recordset

Hi All,
       I am new to SSIS 2012. I am trying to create a package that will loop through a control table and perform a series of task per record. To be more clear this is what i am trying to do.
    *   Read a control plan table into recordset objPlan with 10 columns. ( this seems to be working fine )
    *   Do a Foreach loop that will run a
t-sql task to delete all records from an output table then load new data. (not working)
         @[User::var_Plan_dim] ( is one of the columns on the record set) this is indexed as 1
         I have tried to do a t-sql command
                     delete from table where plan = @[User::var_Plan_dim] ( this does not work )
                     ** I have ResultsSetType set to ResultSetType_None any other options causes error????
        Could you send me a link or show me an example of what the configuration should be for the
Foreach and T-SQL should be?
Thank you in Advance!!!!
I have working on this for days without any luck and I could really use your help...

Hi hsbal,
        I have worked my way through that with your help Thank You...
        But i am having another issue now, in the foreach loop i have 12 variable
      variable                                 index
       User::objplan                       0
object
       User::var_Plan _ dim            1   etc....             string
       User::var_provider_status     11                      string
       when i run the process i get this error:
Error: The enumerator failed to retrieve element at index "11".
Error: ForEach Variable Mapping number 11 to variable "User::var_provider_status" cannot be applied.
Error: The enumerator failed to retrieve element at index "11".
Error: ForEach Variable Mapping number 11 to variable "User::var_provider_status" cannot be applied.
        So should the object variable be indexed 0? I tried taking the objplan off the list of variable and renumber 0-10 and the program didn't like index "1" with the same error, do I don't think
it is really column/field related.
Thanks,

[Forum FAQ] How to calculate the total count of insert rows within a Foreach Loop Container in SSIS?

Introduction
We need to loop through all the flat files that have the same structure in a folder and import all the data to a single SQL Server table. How can we obtain the total count of the rows inserted to the destination SQL Server table?
Solution
We can use Execute SQL Task or Script Task to aggregate the row count increment for each iteration of the Foreach Loop Container. The following steps are the preparations before we add the Execute SQL Task or Script Task:
Create a String type variable FilePath, two Int32 type variables InsertRowCnt and TotalRowCnt.
Drag a Foreach Loop Container to the Control Flow design surface, set the Enumerator to “Foreach File Enumerator”, specify the source folder and the files extension, and set the “Retrieve file name” option to “Fully qualified”.
On the “Variable Mappings” tab of the container, map the variable FilePath to the collection value.
Drag a Data Flow Task to the container, in the Data Flow Task, add a Flat File Source, a Row Count Transformation, and an OLE DB Destination, and join them. Create a Flat File Connection Manager to connect to one of the flat files, and then configure the
Flat File Source as well as the OLE DB Destination adapter. Set the variable for the Row Count Transformation to “User::InsertRowCnt”.
Open the Property Expressions Editor for the Flat File Connection Manager, and set the expression of “ConnectionString” property to
“@[User::FilePath]”.
(I) Execute SQL Task Method:
In the Control Flow, drag an Execute SQL Task under the Data Flow Task and join them.
Create one or using any one existing OLE DB Connection Manager for the Execute SQL Task, set the “ResultSet” option to “Single row”, and then set the “SQLStatement” property to:
DECLARE @InsertRowCnt INT,
               @TotalRowCnt INT
SET @InsertRowCnt=?
SET @TotalRowCnt=?
SET @TotalRowCnt=@InsertRowCnt+@TotalRowCnt
SELECT TotalRowCnt=@TotalRowCnt
On to parameter 1.
On the “Result Set” tab of the Execute SQL Task, map result 0 to variable “User::TotalRowCnt”.
(II) Script Task Method:
In the Control Flow, drag a Script Task under the Data Flow Task and join them.
In the Script Task, select variable InsertRowCnt for “ReadOnlyVariables” option, and select variable TotalRowCnt for “ReadWriteVariables”.
Edit the Main method as follows (C#):
public void Main()
// TODO: Add your code here
int InsertRowCnt = Convert.ToInt32(Dts.Variables["User::InsertRowCnt"].Value.ToString()
int TotalRowCnt = Convert.ToInt32(Dts.Variables["User::TotalRowCnt"].Value.ToString());
TotalRowCnt = TotalRowCnt + InsertRowCnt;
Dts.Variables["User::InsertRowCnt"].Value = TotalRowCnt;
Dts.TaskResult = (int)ScriptResults.Success;
          Or (VB)
          Public Sub Main()
        ' Add your code here
        Dim InsertRowCnt As Integer =
        Convert.ToInt32(Dts.Variables("User::InsertRowCnt").Value.ToString())
        Dim TotalRowCnt As Integer =
        Convert.ToInt32(Dts.Variables("User::TotalRowCnt").Value.ToString())
        TotalRowCnt = TotalRowCnt + InsertRowCnt
        Dts.Variables("User::TotalRowCnt").Value = TotalRowCnt
        Dts.TaskResult = ScriptResults.Success
       End Sub

Can I append the file name from a Foreach Loop Container Enumerator into a SQL Server Statement?

I would like to pass back via an Email the name of the file that was successfully FTP'ed to a remote server. And I was hoping to do this via an Execute SQL Task with the following SQL Statement...but I just don't know if it will append the Foreach Loop Container
variable enumerator to the appended Email message that I am building in SQL Server or if I can and how I can...
I sort of get the feeling that I can try and do this via Dynamic SQL...I just don't know if by building dynamic SQL if my Foreach Loop Container enumerator variable will be appended to my Email Message via the SQL Server UPDATE
@[User::FTPFHFileName]
Or do I add a Data Flow Task and an OLE DB Command and pass the Foreach Loop Container enumerator variable to a Stored Procedure referenced in the OLE DB Command via a "?"
Thanks for your review and am hopeful for a reply.

Foreach Loop Container with a Data Flow Task looking for file from Connection Manager

So I have a Data Flow Task within a Foreach Loop Container. The Foreach Loop Container has a Variable Mapping of User:FileName to pass to the Data Flow Task.
The Data Flow Task has a Flat File Source since we're looking to process .csv Files. And the Flat File Source has a Flat File Connection Manager where I specified the File name when I created it. I thought you needed to do this even though it won't really
use it since it should be getting its File name from the Foreach Loop Container. But when attempting to execute, it is blowing up because it seems to be looking for my test file name that I indicated in the Flat File Connection Manager rather than the file
it should be trying to process in User:FileName from the Foreach Loop Container.
What am I doing wrong here??? I thought you needed to indicate a File name within the Flat File Connection Manager even though it really won't be using it.
Thanks for your review...I hope I've been clear...and am hopeful for a reply.

The Flat File Connection manager's Connection String needs to be set to reference the variable used in the ForEach Loop:

[Solved] Foreach loop that loops over all files in a folder does not consider first file found

Hello,
I have a foreach loop in SSIS (as part of Visual Studio 10 and with SQL Server 2012).
It loops over all files in a folder (ForEach File Enumerator).
I set the folder: OK
Traverse Sub folders: OK
I have set up a Variable in Variable Mappings called FileName so it shows User::FileName: OK
Index of variable is 0: OK
It almost works ok. Except that the first file it finds is never considered.
I set a breakpoint then and the first file it finds, is shown in black in the watch variable window. All subsequent files found are shown in red font. When I change the names of the files so another file is the first file found then it skips the other one
which now is the first file.
What is going on here? Why does SSIS skip the first file it finds in a foreach file loop?
Any suggestions highly appreciated.
Thank you
Andi
Andreas

"red font - interesting, any example to show us (image)
It would be interesting to share with us whether you use any file masks or expressions.

It appears a variable value turns red when it changes between breakpoints. It started black for the first value (the first file, obtained BEFORE the execution reached the breakpoint), and then turned red. I was able to reproduce this behavior on a test environment.
However, it did not skip any files.
OP, please set up the test shown in the image below. Create a breakpoint in the sequence container for the "OnPreExecute" event.

ForEach Loop Container Mapping Variable From SSIS Package Not Working In SQL-Server StoredProcedure

I have an SSIS package that uses a ForEach Loop Container to enumerate Excel Files in a dir. I also have a Task Flow that inserts data from those Excel files into SQL-Server.
Im trying to insert the file names into a column into the same table in SQL-Server by using a mapping variable in my StoredProcedure.
Im having trouble with my MappingVariable at the end of the script with red squigglies. The following is my StoredProcedure script.
CREATE PROCEDURE [dbo].[Insert_F_STG_v2]
-- Add the parameters for the stored procedure here
@Hrs float,
@Type nvarchar(100),
@SN nvarchar(100),
@Op nvarchar(100),
@[USER::CurrentFileName]
AS
BEGIN
SET NOCOUNT ON;
INSERT INTO [CRM_RC].[dbo].[F_StgTbl]
[Hrs],
[Type],
[SN],
[Op],
[Report_Date]
VALUES
@Hrs ,
@Type,
@SN,
@Op,
@[USER::CurrentFileName]
END
The last @[USER::CurrentFileName] in the Values block at the bottom of the script is the one giving me issues.
The following is the error:
Msg 102, Level 15, State 1, Procedure Insert_F_STG_v2, Line 95
Incorrect syntax near 'USER::CurrentFileName'.

This seems to be the solution, but get the following exception:
[Derived Column [2]] Error: The "Derived Column" failed because truncation occurred, and the truncation row disposition on "Derived Column.Outputs[Derived Column Output].Columns[Derived Column 1]" specifies failure on truncation. A truncation error occurred
on the specified object of the specified component.
AND: [SSIS.Pipeline] Error: SSIS Error Code DTS_E_PROCESSINPUTFAILED. The ProcessInput method on component "Derived Column" (2) failed with error code 0xC020902A while processing input "Derived Column Input" (3). The identified component returned
an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running. There may be error messages posted before this with more information about the failure.

SSIS Variable Expression not Picking Up the value dynamically set from a Foreach Loop container

Hello, everyone,
I have three variables in my SSIS package:
1) ReportLoc that holds a file path (c:\test, not changed)
2) ReportFileName that holds a file name that get assigned in a Foreach Loop container (file1, file2, etc.)
3) OutputFilePath that is the full file pathname, set in the expression: @[User::LocalPath] + "\\" + @[User::ReportFileName]
All three variable have the package scope.
I expect OutputFilePath will be asigned values like c:\test\file1, c:\test\file2, etc.
However, it alwasy remains an empty string.
Anything I did wrong? Any help and information is greatly appreciated.
Regards

That's it -- I forgot to set Evaluate as Expression to true.
Thank you very much for your reply and solution! Really appreciate it!

How to bypass errors in the control flow in a foreach loop in SSIS?

Hi All,
Can anyone please get me through the solution for the below scenario:
- I have multiple XML files existing in the source system from where I need to read the data from each XML, validate and pull to staging database.
- So, to read the XML files from source, I have a foreach loop which will get the XML files from the source folder one by one and executes.
- There are multiple data flow tasks, script tasks, SQL tasks etc in the foreach loop to validate the business requirements.
Question: If there is an error in any of the component in foreach loop, it should log the error, come out of the loop from that point and pick up the next file with out stopping the execution. How can I achieve this?
Thanks,
Sri

Hi Sri,
According to your description, when there is an error in any of the component in Foreach Loop Container, you want to continue processing rest of the loop after recording the error file details.
To achieve your requirement, the first thing you need to do is create an OnError event handler for the Data Flow (or any other child executable). Once the event handler is created show the system variables in the variables window, locate the Propagate variable
and set it to false.
For more details, please refer to the following two blogs:

You guys rock. Thanks for finding this problem. I'll get it fixed.

XML Node Selection in Foreach Loop

Good Morning,
I am just building up my first SSIS-package which uses a web service as data source. Now, that I managed the data to be processed using a Foreach Loop, I am wondering how the loop reacts when the sequence of teh nodes changes, or a certain node is not present.
In the "Foreach Loop Editor - Variable Mappings" I have mapped the variables (as they are at the moment) to the certain index (as they appear at the moment), but again: what if an additional nodes comes in? Isn't there a way to explicitly tell the
system to set variable ABC with node ABC, DEF with node DEF and so on...

Good Morning,
am copying in the reply, I receive from the web service which is then stored in the variable:

Using an ssis variable object as a data source in a foreach loop container

hi we run 2012 std. I have an ssis var of type object that is hydrated from a dynamic query in an execute sql task. I can count on one thing in this object and that is that ID will always be the first "col" on each "row".
Otherwise, resultset can contain a variety of things based on params passed to this sub pkg.
I'd like to introduce a for each loop on this object and tap into index 0, ie the id column.
The first question is "will I be able to parse this object's id in a for each component?".
In the for each loop container properties, I c an item enumerator, ado enumerator, ado.net schema rowset and variable enumerator as enumerator choices. Which do I want if the answer to the 1st question is yes?

hoping 2 avoid a data flow. I wonder if what u r saying is that I cannot use an felc to do this. Or if u r showing one of many alternatives.
Sorry, bad title. I just changed that.
I just tried foreach from variable enumerator and aborted with a message that said my variable "coll" doesn't have an enumerator. Going 2 try some of the other choices.
I just tried ado enumerator and from what I can c it isn't actually iterating thru my resultset even once.
I just tried a foreach item enumerator giving "column 0" a data type that matches my ID but from what I can tell the component isn't iterating thru my collection.
ado.net schema rowset doesn't look inviting at all in that it looks like it wants to go back to the db. Not what I had in mind having already gotten this resultset into memory.
according to this article u r supposed to be able to do this using ado enumerator
