How To Get The Return/execution Value Of A Package From A Parent?
May 8, 2007
Hi there,
I'm trying to get the return value of a package. I see there is a ForcedExecutionValue property which I set using an expression (variable). What I'm executing are 2 packages, Package1 contains an Execute Package Task that calls Package 2. Package 2 contains a Script Task that sets the value of variable Max. I want to get the value of Max in Package 1 then how can I do this?
My first approach is toset the return value of Package 2 = Max and then I thought I could retrieve this value from Package 1 but I'm not able to do that yet.
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.
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.
I'd like to know if there's a way to pass parent package parameters to a package executed by SQL Server Job Agent? It appears that sp_start_job doesn't have any variable that could accomodate this.
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.
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...
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 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.
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.
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
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.
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
<Header > Â <detail 1> Â Â </detail 1> Â <Detail 2> Â </Detail 2> Â <detail 3> Â </detail 3> </Header>
I am very new to SQL Server 2005, and I am currently trying to migrate a 2000 db to 2005.
I have now migrated all the DTS to SSIS, removing any legacy & replacing with new functionality.
I have been through a group of related packages ironing out any problems. They ALL now run fine when called individually.
However, I am now having problems with the parent package that is used to string these all together. It will not even run the 1st package.
For info, the first task of this package is a "Transfer SQL Server Objects Task". I am copying a few tables with data, but WITHOUT indexes, etc.
Following this, there is an "Execute SQL Task" that creates an index on one of those copied tables.
To get past another issue I had to set the "CopySchema" property of the "Transfer..." task to true, but did not select any schemas to transfer.
Now, when running the PARENT package, it is failing at the 1st step of the 1st package as follows:
Error: 0xC002F325 at Copy LT Data Tables, Transfer SQL Server Objects Task: Execution failed with the following error: "ERROR : errorCode=-1071636471 description=SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "The statement has been terminated.".

I have been searching and searching, finding similar problems, and even the same error codes, but nothing quite matching this particular scenario.
I have been trying to set the "DelayValidation" at various levels, but with no luck.
I would greatly appreciate any help in trying to resolve this. Has anyone else had the same, or similar, issue?

I have noticed an issue with parent package variables. I have a package with multiple parent package variables defined, call them X, Y, and Z. I also have a parent package that calls this other package. The parent package has variable definitions for X and Z. It seems that the value for X will be passed along, and Y will give a warning since there is no variable of that name in the parent. The issue is that Z will not be passed along. It seems like the parent package configuration process stops after it encounters one missing variable.
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
Hi, I have a child package running under main parent pakage. I am passing value of integer & string type variables from parent package to child package's variables ( as disscussed in following artical http://msdn.microsoft.com/en-us/library/ms345179(SQL.100).aspx) ,values assigned in child package variables are futher used to build connection string for flat file connection manager in child package.
I have been using this whole SSIS package sucessfully for last three months,but suddenly the following error arises
on property "ConnectionString" cannot be written to the property. The expression was evaluated, but cannot be set on the property."
When I see the result of above mentioned expression through Log file than it appears that my string variable
Code Snippet"@[User::StrTextFileImpDirectory]
in child package has not been populated with any value from parent package variable, I.e it has been populated with empty string(While this is not desired value).
Same problem arises with my integer type variable
Code Snippet@[User::Staging_Date_Key]
,it has ben populated with value zero (i.e default value at design time for integer type),while this is not desired value.
Can some one guide me how to figure out the cause for error.... Is it possible that such kind of error may arise due to any change in enviornment of server....
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 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?
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 all, Please help me . please anybody reply ASAP. I have Package_1 in which i have enabled encrypt sensitive info with password. and password is given for this package. I am calling Package_1 from parent package using Execute Package task. when parent package is executed its asking for password for child package. can any one please tel me how can i pass password from parent package or specify password in Execute package task for calling package(PACKAGE_1)
Any help will be highly appreaciated. Thanks in advance. Mahasweta
I am pretty new to SSIS and i found some, (to me) unexpected behaviour. Maybe you guys can help me out understanding it.
I am currently building a multi package ETL solution, that uses parent-package configurations to "distribute" variable values from the "root" package to the lower level and "leaf" packages. Each package contains some 8 parent-package variables.
When i ran the entire solution (i.e. the whole tree) I found that some packages aren't getting the correct values for some of their variables. It seems that if a parent-package configuration that wasn't configured correctly (misspelled parent variable name in this case) blocked the other parent-package configurations in the same package from evaluating. When i moved the correct parent-package configuration to execute prior to the incorrect configuration, it ran just ok.
So apperently parent-package configurations are evaluated one by one, and if one of them fails, the "later" configurations aren't evaluated any more.
Is this a feature? or a bug?
Why don't i get a warning in the error list? Should i maybe configure my BIDS in a different fashion?
Finding myself in a bit of a lull at work, I'm trying to create some template packages / solutions, encapsulating some of the best practices that get discussed on here.
I'm thinking about passing configurations from Parent to Child packages, something we all must do on a regular basis. I've always done this a particular way, without thinking too much about it, but I'm not sure if this way is the best. I'd be interested in your opinions.
Scenario:
Parent.dtsx calls Child1.dtsx, Child2.dtsx etc, using Execute Package Task. Parent has variable Source, and variable Destination, populated from a configuration (my preference is SQL table, but whatever). These variables are ultimately used to populate the ConnectionString property of the source and destination Connection Managers of the Child packages.
Here's the question: Is it better for the Child packages to look up to their parent, and inherit the values of these variables through Parent Package Configurations, or to look directly to the configuration, and pick them up from there? Or does it not matter?
I tend to assign lots and lots of variables in Parent.dtsx, and pull them down into Child.dtsx with Parent Package Configs, but I'm thinking "is this good/bad/unimportant?"
Has anyone seen a problem where if you have several parent configurations setup and one fails to find the variable in the parent, gives a warning, and then does NOT load the rest of the parent configruations? I realize order matters in how your configurations are processed, but I wouldn't expect the rest of my configurations to not work simply because it could not find one parent variable.
The problem only seems to come up when I'm dealing with multiple parent configurations. If I'm loading a variable from a config file and then loading the same variable from a parent variable the process works fine. This way I can handle both cases, when I'm debugging it pulls from the config file, when it's running in production it pulls from the parent variable.
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.
I have declared a variable XYZ in Parent package Similarly I have declared ABC in Child package and have done the configuration. I have assigned some value to XYZ How to get the value in Child Package.
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.
How can I specify the target object when trying to set a parent variable package configuration programatically?
I am trying to set the Target Object to be "ParentLogID" and the Target Property to be it's "Value". I think this is how I'd add the configuration and set the source.
