Passing Multiple Values From Parent To Child Package
Dec 20, 2006
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:
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...
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.
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.
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.

How can I pass configurations from Parent Packages to a child package? I am using Execute package task to execute a child package but am unable to configure a variable to pass configurations to a child package.
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.
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?
I am in the process of creating a Report, and in this, i need ONLY the row groups (Parents and Child).I have a Parent group field called "Dept", and its corresponding field is MacID.I cannot create a child group or Column group (because that's not what i want).I am then inserting rows below MacID, and then i toggle the other rows to MacID and MacID to Dept.
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:
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
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.
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.
May be I am doing something wrong over here, but I have been trying in vain to test out a simple scenario where I can use my Parent Package configurations in my Child package. I have two packages ready and can someone please walk me through this process. Appreciate all help
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?
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.
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.
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.
I have a parent Child attribute in my dimension. I am currently displaying the correct ID value as the business wants. So now they can see the rollup of the ID(intOrgNodeID ) values.They would also like to see the same rollup of the Name (vcharOrgNodeName)  for this ID.However they do not want it concatenated. They want to be able to see them separate.You cannot create two parent child attibutes in one dimension so not sure if there is some simple trick to make this work? It seems like there should be some simple trick for this.Â
My dimension table looks something like this intdimOrgNodeID int Key (surreget key) intOrgNodeID int (Actual ID) intDimParentOrgNodeID vcharOrgNodeName In the Propertys I have set this below. KeyColumns = tbldimOrgNode.intDimParentOrgNodeID NameColumn = tbldimOrgNode.intOrgNodeID
So I have a parent package that calls another package using the Execute Package Task. When I run the child it runs fine but when I run it from the parent i get this msg...Any ideas?
Error: 0xC00220E4 at Execute VR Account Load: Error 0xC0012050 while preparing to load the package. Package failed validation from the ExecutePackage task. The package cannot run.
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.
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?
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??
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?
I am sure someone must have run into this before. I have a couple of tables with a parent child relationship.
I created a trigger on the insert of the parent but don't want it to fire until both the parent and child have been inserted into.
However sometimes the child may not get inserted in to at all. In other words it is a 1 to 0 or more relationship.
I created the whole insert into the parent and the child and wrapped it all up in a transaction hoping that the trigger would not fire until the transaction actually completed.
However such is not the case and it fires when the parent is inserted into but nothing is inserted into the child yet even though that is part of the transaction.
Is it possible to postpone trigger fire until after both parent and child table values have been inserted?
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
The query repeats the Header row value for all children associated with the header.I need the output of the query in XML format such that..For every Header element in the XML, all its children should come under that header element//I am using -Â
SELECT Cols FROM Table Names FOR XML PATH ('Header'), root('root') , ELEMENTS XSINILÂ
This still repeats the header for each detail (in the XML) , but I need all children for a header under it.I basically want my output in this format -Â

I want to eliminate the repetitive question and group them as parent child items.

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.
