How To Use A Variable From The For Loop Container As A Input Parameter To A SP

Nov 6, 2006

Hi Everyone:

I have a quick but imp SSIS question. I have a For Each Loop Container, and inside that I wish to add a Execute SQL Task item, so I can call a sp to do some inserts/updates. The ForEachLoop container is looping thru a ADO Object source variable(which is the user variable defined by me, as a FullResultSet). In my Execute SQL Task, I would like to utilize one of the columns from the result set as an input parameter to my Stored procedure. Can someone please advise on how to do this? Please let me know if you have any more questions. I am waiting for a response... Thanks in advance.

MERGING Variable In FOR LOOP COntainer

Mar 23, 2007

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]

Using Array Variable In ForEach Loop Container

Mar 1, 2007

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

Variable Mapping And Index For The Foreach Loop Container.

Jul 25, 2006

Hi:

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

AK

SSIS: Fpreach Loop Container- Execute SQL Task With ReturnValue Parameter

Jun 9, 2006

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

I've encountered a new problem with an SSIS Pkg where I have a seq. of Execute SQL tasks. My question are:

1) In the First Execute SQL Task, I want to store a single row result of @@identity type into a User Variable User::LoadID of What type. ( I tried using DBNull Type or Object type which works, not with any other type, it but I can't proceed to step 2 )



2) Now I want to use this User::LoadID as input parameter of What type for the next task (I tried using Numeric, Long, DB_Numeric, Decimal, Double none of there work).

AssignExpression In For Loop Container

Feb 27, 2006

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,

Brian Layden

Probelm Using For Each Loop Container

May 18, 2007


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?

For Loop Container With Dates

Apr 25, 2007

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!

For Each Loop Container In SSIS

Mar 12, 2008



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.

For Each Loop Container Do Nothing Inside

Aug 27, 2006

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.

Expressions In For Loop Container

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,

ForEach Loop Container Question

Nov 6, 2006

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.

For Each Loop Container File Enumeration

Feb 27, 2008



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?

Execute Package On A For Each Loop Container

Apr 18, 2006

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.

FOREACH Loop Container: Continue ?

May 26, 2006

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

File Metadata And The Foreach Loop Container

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!

Foreach Loop Container Does Not Iterate Automatically

Sep 19, 2007

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.
