Parent / Child Package - Connections, Variables Etc.,
Aug 13, 2007
In respect to Parent / Child packages, can some one correct me if I'm wrong.
Even if connection managers are created in Parent package, the same needs to be created in child packages if they need to connect to database. On the other hand I can just create connection strings in variable in parent package(instead of connection managers itself) and use parent package variable configuration to configure the connection string of child package with the variable value.
Sorry If I'm confusing
The same with variables, the parent variable needs to be mapped to a child variable(using parent package variable config) to be used in child package, it cannot be used as it is.
Thanks

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.

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.

hi,
I am interested in Passing value from a child Package variable to the Parent package that calls it in ssis.
I am able to call the Child package using the execute package task and use Configurations to pass values from the parent variable to the child, but I am not able to pass the value from the child to the parent.
I have a variable called datasetId in both the parent and child. it gets computed in the child and needs to be passed to the parent...
Any suggestions?
Thanks for any help in advance..

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.

Given the sample data and query below, I would like to know if it is possible to have the outcome be a single row, with the ChildTypeId, c.StartDate, c.EndDate being contained in the parent row. Â So, the outcome I'm hoping for based on the data below for ParentId = 1 would be:
1 2015-01-01Â 2015-12-31 AAÂ 2015-01-01Â 2015-03-31Â BBÂ 2016-01-01Â 2016-03-31Â CCÂ 2017-01-01Â 2017-03-31Â DDÂ 2017-01-01Â 2017-03-31
declare @parent table (Id int not null primary key, StartDate date, EndDate date)
declare @child table (Id int not null primary key, ParentId int not null, ChildTypeId char(2) not null, StartDate date, EndDate date)
insert @parent select 1, '1/1/2015', '12/31/2015'
insert @child select 1, 1, 'AA', '1/1/2015', '3/31/2015'
[Code] .....

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?

I have two SSIS packages in a project, one calling the other. The parent package works fine in my local mechine. After they are deployed to the production, I schedeul jobs to run the packages in the SqlServer. The child package works fine if I run it alone, but the parent package could not find its child package if I run the parent package . As I checked, all xml config files and the connection string pointing to the child package were set correctly. It seems the parent package did not use the xml config file. Can someone help me? Thanks in advance.

Hi there,
sorry if the message seems a bit garbled i cannot see the textbox properly with ie7/ff
anyways. the situation.
childpackage contains a loop-container. in there i use an ole-db-source with a variable
based on an expression. ie. "select * from foo where bar=" + len(@[bar]) == 0 ? "initial" : @[bar] + " and etc=1"
where bar is the variable that is set by the loop.
this works great.
however i need to call this package several times, only the expression is a tad different.
so i need a scripttask that sets the expression correctly, then i call the childpackage
and map the current-expression to the expression in childpackage.
how do i do that? or am i doing it wrong?
my script-task looks something like:
dts.Variable("theVar").Expression = " ""select * from foo where bar="" + len(@[bar]) == 0 ? ""initial"" : @[bar] + "" and etc=1"" "
in the childpackage i have a package-conf that maps thevar to thequery with target-object expression.

I have an ASP.NET application that calls a SSIS package. The SSIS package internally calls some other child packages. I observed that sometimes some child pacakges are not even called by the parent. and the behaviour is very indeterminate. sometimes they work fine. sometimes they don't. There is no clue available for this behaviour when the pacakges are not executed. (One general observation is that the memory consumption is very high. but that is the case always.)
I have enabled logging on all child packages. The log is not updated at all when the child packages failed to execute. i.e. the package execution does not start.
Could somebody explain why this is happening? any suggestions/ similar experiences?
Regards
Saurabh

I am trying to figure out how to run an SSIS package that is encrypted but also has a child package which is encrypted. I am trying to run from the cmd line using dtexec and specifying DECRYPT <pwd> for the parent package but how do you specify for the child package.
Please help if you have seen such an issue before or you have a work around.
Thanks

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??

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.

I have a parent package "A", I also have 4 child packages "B","B1","B2",B3"
In BIDS, I created a file connection in the package "A" to connect to the child packages. So whenever I want to run B1 or B2, I change the path in the file connection to point to B1 or B2 and so on. Since the developement environment is File system this works perfectly fine.
But in the Test / Production environment all packages are stored in the Sql server. How can I paramaterize the child package connection so that I can use configuration / variables to select which child package to execute.
Thanks

Starting with "How to: Use Values of Parent Variables in Child Packages" in the SQL Server 2005 Books Online (http://msdn2.microsoft.com/en-us/library/ms345179.aspx), it seems I need to create a separate package configuration in the child package (of type parent package variable) for each variable I want to pass from the parent to the child. Is that really so? The XML configuration file type allows me to specify any number of variables; how do I do that with the parent package variable?
For that matther, why doesn't the Execute Package Task simply allow me to specify the values of child variables (or other properties) directly? It seems SSIS has made something as trivial as a series of function calls completely opaque:
MyChildPackage(var1=1, var2="foo");
MyChildPackage(var1=2, var2="bar");
MyChildPackage(var1=3, var2="baz");

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.

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,
Gordon Radley

I have two issues:
I have a simple parent that uses an Execute Package Task to call a simple child package. The child package has a Data Flow that I disabled. When running the child package by itself, the data flow task is bypassed. When running the package via the parent the data flow task executes.
Second issue is when you disable the package configurations in the child, the parent doesn't recognize that it's diables and tries to load the configurations.
It's almost like there are some settings in a child that get ignored by the parent??
Anyone else experience this?
thx

Hi,
I've found this problem that when I change settings in my configuration file it does not automatically apply to all child packages which uses the same configuration file if run from a job in SQL Server Agent. I need to open the package and save it again from BIDS. I use one "load group" package to execute all other packages.
Is there a way from the job configuration to set a setting so the package allways will have the newest configuration?
Regards
Simon

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

Hello All,
I have a Master Package which calls a group of other packages out on the SSIS Package Store using parent / child and a number of variables. These seem to work when passing various audit information (audit key, record counts, etc) but when I try to pass a variable for the connection string and assign it via an expression to the connection manager, I get the Master Package writing to the correct database and the children package writing to their "default" database which is supplied as the default value in the variables which should be populated by the parent task.
i.e., I end up with my master package audit information in database a and child package audit and transactions in database b, even though the packages associated with these transactions are supposed to be reading the connection string from a parent variable. Any clues or suggestions?
Edit: It is still passing along the correct parent audit information and record counts, it's just not connecting to the correct database by the variables holding the connect string
Thanks for your time.

Hi,
I am sending variables from package to package by configuration parent packages in each package...
I usually set logging to text files in a certain path that should be received from the parent variable... the strange thing is that if i let the variable in the child package with an incorrect path, my package just through an error even if i am passing the variable from the parent with a correct value...
So... my question is... does my package starts execution without any synch over the parent packages? When are they set? How can i be sure to start my logging with the right parent variable settings?
You can try for example to create a package... add a new variable like "A" and "B" set its value to a default string like "I DONT WANT THIS", add an Execute SQL Task that will record the values of "A" variable to a temporary table...
Then use dtexecui.exe to execute the package and set variable "A" to "THIS IS WHAT I NEED" you will see that in the table will appear one record with the "I DONT WANT THIS" value...
I can't understand this...
Also... if i have 100 variables configured to get values from the parent... is the execution synch or asynch?
Best Regards,

I have read a few different threads on this and I am still not having any luck. I have 4 dtsx files in my project. One represents the parent package. I have set up 3 Parent Package Variables and have assigned each to the value property of 3 variables within the parent package.
Not sure if I did this correct because when I execute the parent package, it in turn executes the first child package, but the child fails because the variables needed did not set the correct value for a connection string in the child's data connection.
I just need to know how to use these parent variables from Package A within the child (Package B) when setting up my expression for a connection- example: "@[User::varParentFilePath] " - This is the local variable name in the child. This is the variable I am assuming that I am supposed to be able to set the value property of from the parent variable?
I feel that I am close, but may need a little more direction. Thanks

Hi,
Let's say I have a package taking as parameter "InvoiceID". I want to execute this package as a child in another package. The parent package gets the list of invoices to produce and calls the child package for each entry of the list.
How do I pass the InvoiceID to the child? I know I can use the parent's variables from the child but I don't want the child package to be dependant on the parent package. For example, I might want to execute the "child" package as a stand-alone in development (providing it with a predefined InvoiceID). I might also want to call the same child package from another parent package with other variable names.
What I would like to do is "push" the value instead of "pulling" it. I know it's possible using the command line and the /SET option (ex.: /SET Package.Variables[InvoiceID].Value;' 184084)... Is it possible using the Execute Package Task?
Thanks

I want to achieve the following in (SSIS/SSDT for SQL 2012) -Â
I have a generic SSIS package which simply sends out email notifications using SMTP email task (this package is within its own project, and has project level input parameters).
I need to be able to call this package in the Event handler section of every package (numbering in about less than 60) that we have. These packages are within their own respective projects.
I thought I could use the "execute package task", but it turns out , using this, I cannot call a package that is part of some other project. I also cannot call a package that is stored in the CATALOG. Is there any way I can do this ?
When I call the child package , I should be able to send in parameters like - error information and package name of the Parent package.
