Variable In A Foreach Loop Becomes NULL When Package Executed As Child Package

Dec 3, 2007

I have created a SSIS package with a Foreach Loop including a Data Flow Task, which in turn include a Row Count component which pass the row count value to variable with package scope. The variable is used in an Execute SQL Task following the Data Flow Task.

The package executes successfully when executed on its own, but when executed as a child from a parent package (which only include an Execute Package Task) the variable from the Foreach Loop becomes NULL.

There are a lot of other variables in the package receiving values dynamically without any problem, the row count variable however is the only variable in the package that receives a value as part of a Data Flow (and used in following tasks within the Foreach Loop).

Why does the variable become Null? For your information, I am using a variable with package scope and no variables from the parent package are used or passed from the child package to the parent package.

(For your information, we are running the 64 bit version)

Parent Package Variable Assignment Issue In Child Package.

Dec 26, 2006

We
have one main package from which 7 other child packages are called. We are using
ParentPackage variables to assign values for variables and database connections.

While the values from ParentPackage variable get assigned to some of the
packages properly, to others it doesn��t assign the value.

For example:
Except for one of the packages the database connection string gets assigned
properly to all other packages.

Similarly, in another package one of the
variables doesn��t get assigned. In other packages it is assigned properly.

We
have checked all the other property values and they are exactly the same.

We cannot make any head or tail of this erratic behavior.

Please Help.

How To Get A Variable Value Return Back From A Child Package ?

Sep 29, 2006

I have a parent package (i.e. P) and a child package (C). I was able to easily pass a variable value from P to C. And C did computations and get a result (i.e. integer) and stored this integer to a variable (x).

Now I want the value of "x" to be passed back to P and store in P's variable (say Px). Anyone knows how to ?

Thanks

Checking For Existence Of Parent Variable In Child Package

Oct 16, 2007

I have a parent package that calls a child package, when I run the parent package the child package picks up a variable value from the parent in a script task and runs fine, the problem I'm facing is when I run just the child package, the script task fails because it doesn't know about the parent variable. The dilemma I'm facing is in my child script task, if I add the parent variable to the ReadOnlyVariables list then the task fails because the parent variable doesn't exist when I just run the child. If I don't add the parent variable to the ReadOnlyVariabls list then if I try to use it then the task fails saying that the variable doesn't exist in the variables collection.

Is there a way to check for the existence of the parent variable, so when I just run the child package I don't get an error and I don't have to change my task every time I choose to run the child package only vs running the parent/child?

Thanks.

SSIS Parent/Child Package Variable Passing

Feb 7, 2006

Hi

I have having trouble getting my hands around how to retrieve variables from a parent package. I read about the Environment variables and Configuration File at the parent package level and the Parent Package variable at the child level.

Here are my questions:

1. Can you only store/retrieve 1 variable in a config file at a time?

2. Does the child package have to define the variables and if so, do they have to be the same names as the parent package?

This seems so more more complex then the DTS2000 way of passing variables to and from packages.

Any help would be appreciated.

Thanks in advance,

Passing A Variable Between A Parent And Child Package Doesn't Work

Apr 7, 2006

Has someone managed to pass successfully a variable from a parent package to a child package? I��ve tried a zillion permutations and I can��t get it to work. The strange thing was that I was able to successfully do this with pre-RTM builds. Basically, what I am trying to do is:

The parent package has a variable, e.g. ExecutionID which I set using a script to System::ExecutionInstanceGUID. I verified that the variable is set correctly by dumping it to a SQL Server table.
I created a child package variable with the same name.
In the child package, I��ve created a parent package configuration that points to the ExecutionID variable.
I am trying to read the variable in a Derived Column Task in which I have a column linked to @ExecutionID.
This doesn��t work. Step-by-step instructions from someone who managed to concur this will be greatly appreciated.

Oh, I didn��t have any luck hitting a breakpoint in a script task inside a child package with both in and out of process execution also.

Hi,

I having a problem getting the child package variable values into a parent package. Here is the scenario;

I have parent package(Master) calling two child packages using execute package task. I have no problem to pass variable values from the parent to child using the parent configuration but not able to get the variable values from the child to parent. I am setting the package status in each child package based on certain conditions and determine the final status in a parent based on child package variable statuses. Does any body have any idea? I will appreciate your thoughts.Thanks..Mako

Execution Of Child Package From Parent Package In Sql Server 2005 Integration Services

May 21, 2007

Hi,

I created a package which passes some infornmations( through parameters) to its child package.

I need to do some processing in parent package based on execution status of child package.i.e.

if child fails then some operation and if child succeeds then other operation.

To determine the status of execution of child package I am using two differnt constraint ..one constraint is having value "Success" and other having value "Failure".

My problem is that when child packge is executed successfully the constraint with value = "Success" works properly but when child fails the constraint with value "Failure" does not work.

Problem When Running A SSIS Master-package-child Package On Non Default Sql-server Instance

Dec 6, 2007

Hi there

We have a SSIS run which runs as follows

The master package has a configuration file, specifying the connect strings
The master package passes these connect-strings to the child packages in a variable
Both master package and child packages have connection managers, setup to use localhost. This is done deliberately to be able to test the packages on individual development pc��s.
We do not want to change anything inside the packages when deploying to test, and from test to production. All differences will be in the config files (which are pretty fixed, they very seldom change). That way we can be sure that we can deploy to production without any changes at all.

The package is run from the file system, through a job-schedule.

We experience the following when running on a not default sql-server instance (called dkms5253uedw)

Case 1:
The master package starts by executing three sql-scripts (drop foreign key��s, truncate tables, create foreign key��s). This works fine.

The master package then executes the first child package. We then in the sysdtslog get:

Error - ��cannot connect to database xxx�?
Info - ��package is preparing to get connection string from parent ��?

The child package then executes OK, does all it��s work, and finish. Because there has been an error, the master package then stops with an error.

Case 2:
When we run exactly the same, but with the connection strings in the config file pointing to the default instance (dkms5253), the everything works fine.

Case 3:
When we run exactly the same, again against the dkms5253uedw instance, but now with the exact same databases defined in the default instance, it also works perfect.

Case 4:
When we then stop the sql-server on the default instance, the package faults again, this time with

Error - ��timeout when connect to database xxx�?
Info - ��package is preparing to get connection string from parent ��?

And the continues as in the first case

From all this we conclude, that the child package tries to connect to the database before it knows the connection string it gets passed in the variable from the master package. It therefore tries to connect to the default instance, and this only works if the default instance is running and has the same databases defined. As far as we can see, the child package does no work against the default instance (no logging etc.).

We have tried delayed validation in the packages and in the connection managers, but with the same results (error).

So we are desperately hoping that someone can help us solve this problem.

Thanx,
/Nils M - Copenhagen

Configure A Child Package To Use The Configuration File Of A Parent Package?

Sep 14, 2006

Hi guys,

Here's the deal. I have a child package, (say, pack01.dtsx), which uses a dtsconfig file for its connection string, which can be called from other packages, but which also can be called by itself.

However I also have another package (say, pack02.dtsx) which uses the same dtsconfig file for its connection string. It calls on pack01.dtsx.

When I use DTEXECUI and run pack01.dtsx, specifying the proper .dtsconfig file, it goes well. But when I try and run pack02.dtsx, an error occurs saying pack01.dtsx connection cannot be established.

How do I pass the connectionstring being used by pack02 to pack01, without having to remove the configuration file setting of pack01? Can a Parent Package configuration and a configuration file try and map to the same property?

Hope someone could help. Thanks.

Resume Parent Package After Child Package Failure...

Apr 23, 2007

Hello All,

I have a SSIS Package with a "Execute Package Task" to call a child package. I am trying to have the master/parent package complete its execution regardless the outcome (failure or success) of the child package. The overall structure of the master package is:

1. Perform Pre-load tasks (stored procedure).

2. Execute Package Task (call child package)

3. Perform Post-load Tasks (stored procedure)

I have try everything and cannot get the results that I want... I have tried the combination of "failparentonfailure", "forceexecutionvalue", etc. The master package stops at childs failure. I would like to resume to completion

Any ideas out there?

Package Is Not Able To Create Process To Execute Child Package.

Hi,
In my application, i have two package, parent package and child package. the parent package is executing child package using a Execute Package Task.
"Execute Out Of Process" property of Execute Package Task is set to TRUE. means the child package will be run in separate process not in the process of Parent package.
this was working fine, but at a particular client location. its failing the error is "not able to load child package".
for me it seems some setting on server restricting to create separate process for child package execution.
when "Execute Out Of Process" property of Execute Package Task is set to FALSE. its working fine.

can anyone help what could cause its failure with property set to TRUE.

Appreciate any help.

Parent Package Is Losing A Child Package

Dec 4, 2006

I have a parent package which calls a number of child packages. Occasionally, I have one child package which starts up and appears to finish but the parent package never gets notification that the child has finished. If I view this in Management Studio's in Integration Services, I can view the packages that are running and only the parent package is running. Because it never gets control back, the next child package will never get started and the parent package will continue to run and never finish.

Any idea what could be happening??

There's nothing more to go on here in the log.

Parent Package Call To Child Package

Apr 30, 2007

I run into some issues and really need some expert help here.

Here is the problem. I have two packages (parent.dtsx and child.dtsx). Both package have its own configuration file (parent.dtsConfig and child.dtsConfig). The file Child.dtsConfig contains a variable (i.e. "X") that is to be used by Child.dtsx.

Inside parent.dtsx. there is a package-task that calls into Child.dtsx. It worked perfectly well if I run parent.dtsx using Dtexec or from inside SSIS's IDE.

Now I want to programmably call "parent.dtsx" from my C# code. I loaded package using "app.LoadPackage"... Inside C# code, I want to reconfigure Child-package's variable ("X"). I then loaded in "Child.dtsx". However when I run "parent.dtsx" and child.dtsx still loads the original value for "X". The reconfigured value for "X" is not updated.

Please help on how to get around this issue.

Thanks.

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

Using Variable Of Foreach Loop - File Enumerator

Jun 6, 2006

I have a Foreeach loop container that is looking for all the files in a specified directory. For each file in the directory I need to open the file, extract the contents, and pass the contents as a variable for a stored procedure call.

I was able to loop thru the files in the directory and see each file and store the name to a variable.

I was able to use an XML task to open one file via a file connection that connects to a specified file and store the contents in a variable and then execute the SQL task using the variable.

What I am unable to figure out is how to put the two processes together and get the XML task to open the file by using the variable that contains the filename. If anyone could help I would really appreciate it.

Thanks!

Integration Services :: Variable (Excel Tab Name) In Foreach Loop

Oct 3, 2013

I have to import a number of excel spreadsheets. I'm using the classic Foreach Loop inside another Foreach loop approach. The outside loop (Foreach File Enumerator) cycles through the Excel files, while the inside loop (Foreach ADO.NET Schema Rowset Enumerator - ExcelSchema - Tables) to cycle through the individual Excel sheets in each file.

Nothing special there; however, for some reason these excel files have some "phantom" tabs that should not be imported. I call them phanton because they show up as an importable tab in a SSSIS import wizard but actually are not listed in the excel file structure (no, they are not hidden tabs, I checked).

My idea is to use a constraint to NOT import those phanton tabs. The name convention should allow me to do that because the normal tabs have the name 'AAAAAAyyyymmdd$' and the phantom tabs show up as 'AAAAAAyyyymmdd$'_xlnm#_FilterDatabase (the line below was captured from the Local Variable window and show one of the phantom tabs name).

+ User::WorksheetName {'AAAAAAyyyymmdd$'_xlnm#_FilterDatabase} String

I tried using Len (@[User::WorksheetName]) == 17, which corresponds to the length of the normal tabs name ('AAAAAAyyyymmdd$'). However, it does not work. For some reason the portion of the phantom tab name after the ending single quote (_xlnm#_FilterDatabase) appears to be ignored.

I tested with a number of different expressions, including reversing the variable, to no avail. It seems that internally just the standard name between quotes is what the constraint sees.

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

Run Package On Server CPU Is Done Through SQL Agent: How To Set User Variable In Package Then?

May 9, 2007

Hi,

I have packages stored in SQL store. I was letting users run the packages from a .net app that I made with

Microsoft.SqlServer.Dts.Runtime

Now I have noticed this causes the packages to run on the client pc cpu, as well as the network traffic is done via the client pc, in my particular case this is slow.

From the doc and in this forum I have found that you can run a package on the Server cpu through sql agent, let packages be run in a sql job. after that you can start a package from an application with the SQL sp_start_job .

But How do you set a user::varibale in a package if you have to start the package from a sql agent job ?

SSIS Package Not Getting Executed From The Code.

Dec 17, 2007

Hi Friends,

I am a newby to SSIS and it has been around 2 weeks since I have started with SSIS in my project.

Now, I have been able to successfully build the SSIS package for my project need which is to export all the data from excel source file to the destination database tables after certain validations and modifications. So, when I run the package from the Visual Studio, it runs fine, but actually we have to call the SSIS package from the Webpage through ASP.NET. I have used following code, for loading and executing the package on the page load event.

protected void Page_Load(object sender, EventArgs e)
{
Application app = new Application();

// Load package from file system
Package package = app.LoadPackage("C:\Monitor 3\EEObjectImportSSISPackage\ImportCustomPointObject.dtsx", null);

Variables vars = package.Variables;
vars["selectedArea"].Value = 1050;

DTSExecResult result = package.Execute(null, vars, null, null, null);
}

All the connections and the log details are configured in the package itself. I am not much expert on the how to configure the package properly, as this is my first hands on effort at SSIS.

Unfortunately, I am not able to execute the package from the above piece of code. I have tried referring to various blogs, but none could come to my rescue. On the page load, it generates the log which notes below errors.

#Fields: event,computer,operator,source,sourceid,executionid,starttime,endtime,datacode,databytes,message

Getting Error Context From Executed Package

Aug 7, 2006

Background:

I am executing a package programmatically from ASP.NET using C#. The package is being loaded from SQL Server at runtime and then it is executed from a custom class written in C#.

Problem:

When a task fails, I'd like information on why it failed. I read about implemeting the IDTSEvents interface as a way to have my package call back to code. This works fine (I have code in the OnTaskFailed event handler), but I'm not sure how to find out why a task failed. Since my task is loading a flat file to SQL Server, failure will likely come in one of two flavors: either the file format will be wrong or the data will violate a database constraint. In etiher case, I'd like that feedback. I am looking that the TaskHost object that gets passed to my event handler and I haven't figured out how to access this information. Am I going about this the right way? If yes, how do I access the error information I am looking for?
