I have a master package which calls two package one after an other.
1) I will be passing parameters to master package using dtexec with /set property to set the variables in the master package. I would like to know how can child package access these variables.
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 - €ścannot connect to database xxx€?
Info - €śpackage 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 - €śtimeout when connect to database xxx€?
Info - €śpackage 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,

Is it possible to call a package through the 'Execute package task' and force it to run in 32 bit while the master package runs in 64 bit?
View 1 Replies View RelatedI 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)
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.
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

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,

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
I have been using SSIS for a while now, originally in SQL 2008 but more lately SQL 2012.
I discovered the GETDATE() function in SSIS so I thought I would use this in a variable expression in a Master/Driver package with the child parameters mapped to this variable. A big mistake. The value is not persisted, it gets updated each time the variable is read, so it's back to setting the variable value using a script task in the Master/Driver package.
Has anyone ever used an Execute Package Task to call a child package, and the Execute Package Task's ExecuteOutOfProcess = True? Unless the account it runs under is an Administrator on the box, it fails for me with "Error 0x80070005 while loading package file "C:program filesmicrosoft sql server90dtsPackagesETLFact_SalesTransaction_Tracking.dtsx". Access is denied."
This is eating up hours and hours of my time, time we can't afford. Is anyone able to successfully call a child package out of process?
I have a master package that contains an Execute Package Task whose ExecuteOutOfProcess flag is True, and that calls a child package whose TransactionOption = Required. The job is running in Sql Agent, and the step that calls the master package is configured to run under a certain domain account that is not in the local Administrators group. With this, I get the following:
messageText: Error 0x80070005 while loading package file "C:program filesmicrosoft sql server90dtsPackagesETLFact_Various_TransactionalChannels.dtsx". Access is denied.
When I add the domain account to the local Administrators group, this error does not occur. From a blog entry, I read that when a child package is executed out of process, the resultant OS process is called dtshost.exe (http://blogs.conchango.com/jamiethomson/comments/1414.aspx). Do I simply need to give my domain account permission to spawn this process? If so, what permission is it? Is there a group that contains this permission?
Hello,
I have a package variable called LatestTableFileDate that is typed to DateTime. I have an Execute SQL Task that executes the following SQL statement against an MS Access 2000 database table through the OLEDB Jet provider;
SELECT MAX(FileDate) AS MaxFileDate
FROM CollectionData_Access
The statement parses fine. At the moment, the returned value is NULL. I have 'Result Set' set to 'Single Row'. The FileDate column in the Access table is 'Date/Time', and the Format is 'Short Date'.
In the result set properties, I attempt to set the result to the LatestTableFileDate user variable. When I run the task, the task fails, and the following appears on the 'Progress' tab;
[Execute SQL Task] Error: An error occurred while assigning a value to variable "LatestTableFileDate": "Unsupported data type on result set binding 0.".
I searched the forum for this problem, and didn't find anything. Do I need to convert the date in MS Access to a string and set the package variable to a string type, or is there some other way to handle this?
Thank you for your help!

Hi Guru's,
I am facing a problem in deploying the SSIS packages.
My Scenario is like this
1. Have one Master SSIS Package.
2. Master SSIS Package inturn calls 3 Different packages using execute package task.
3. I have a common Configuration file for all these packages.
4. I am using File System deployment.
5. I have imported all the packages i.e master and the 3 child packages using SQL Server management studio.
6. Now i have created a job, and added the master package as a step.
7. I have a variable declared in the configuration file and the child packages will be getting their path from this variable.
The problem since i know the imported packages lies in "C:Program FilesMicrosoft SQL Server90DTSPackages<<Folder Name>>" i have poited the child package variable to point to this directory.
I still want to import all the packages and want to get this directory info dynamically thorugh the script so that i can assign this at run time.
I am using "Directory.GetCurrentDirectory" But it's giving me a different location when we run the master package.
Can any one has any idea or comments how to retrive the path of the master package?
Even a work around or any other option is also fine....
Regads,

Hi,
I need to insert a record in a master table and 20 records in a child table. I want to do this using stored procedure. Is it better to do it in stored procedure? Have somebody already tried this? Or is there any sample that I can use?
Thanks a lot!
I have around 10 packages for dim and fact Table load. Using deployment Utility i create setup and put the packages in to test environment.
Now my requirement is call all the packages in certain order from single package. Using Execute Package Task i could call only one package. how to achive this in deployment?
Thanks

I have a situation here. Please
advice me on this.
I have a master table and a child
table. They have a PK and FK relationship. The master table has an identity
column with auto increment set to true. This map as a FK in the child table. My
questions are:
Can I have a single form to insert a new record into
master and child table at the same time?This has to be accomplished without stored
procedures. Can it be done?Is it possible to do this with a single insert query?
If yes, can it be done with sql data source or
dataset or tableadapters’?Please point me towards appropriate link for doing
so.
Thank you.
I am currently using SQL Server
2005 and VS 2005.
Hi All,
In my DataFlow i have OleDBDataSource and OleDB Command. Using these i am inserting data to master and child tables.
In OleDBDataSource , i am inserting into master table and returning the ID of newly inserted rows. Next in the OleDB Command, i am inserting to child table using the ID returned from OleDBDataSource.
It is working fine. Now i want to put this in the Transaction so that if it fails to insert into child table, the changes made to the master table should be rolled back. I tried by giving Transaction Supported for dataflow. But does not looks like it works for me. Please suggest me the best approach for this.
Thanks in advance

I have 6 tables which are very huge in row count and need to be partitioned for better manageability.
Little info: Every day, 300 Million records are inserted and 300 million records are deleted in below 7 tables. we maintain only 8 days worth of data in below tables which is the reason records which are older than 8 days are continuously deleted.
Master table which has [ID],[Timestamp]
Table Name: Sample - 2,578,106
Child tables: Foreign key [ID] is common for all the tables. There is no timestamp column in child table.
dbo.ConnectionDB - 1,147,578,048
dbo.ConnectionSS - 876,458,321
dbo.ConnectionRT - 118,133,857
dbo.ConnectionSample - 100,038,535
dbo.Command - 100,032,235
I would like to partition the above child tables based on the IDs that are inserted every 4 hours. Meaning, All IDs that are inserted in 4 hours window should be in a partition.
I have 6 tables which are very huge in row count and records needs to deleted which are older than 8 days.
Little info: Every day, 300 Million records are inserted in below 7 tables. we should maintain only 8 days worth of data in below tables. How to implement Purge script which can delete records in all tables in the same time and with optimized parallelism.
Master table which has [ID],[Timestamp]
Table Name: Sample - 2,578,106
Child tables: Foreign key [ID] is common for all the tables. There is no timestamp column in child table. So the records needs to deleted based on Min(ID) from Sample
dbo.ConnectionDB - 1,147,578,048
dbo.ConnectionSS - 876,458,321

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.

I am developing an application in vb.net 2005 using SQL Server 2000.
In this I have two tables SessionMaster and SessionChild.
Fields of session master - SessionMastId, Start_Date, End_Date, Session_Type,
Fields of session child - SessionChildId, SessionMastId, UserName, Comment.
SessionMastId and SessionChildId are primary keys of respective tables and also they are auto increment fields.
Please how to write trigger to insert record into both tables at a time.
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..

I use a execute package task to run a child package in which I run some sql task.
as the error handle I insert a script task and link a line from execute package task to script task
of course the line is red,
but I found when the child package failed, the execute package task turns red,it stopped
the script task can't be run, I don't konw why?
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.
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.
View 9 Replies View Related 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.
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 need to pass variables from the parent package to the child package. I got this to work in a small test case. But in the actual project, I get an error when I try to do that. The parent package's log has this error :
Error: Error 0xC0012050 whike loading package file "c:.......". Package failed validation from the ExecutePackage task. The package cannot run..
There's nothing more to go on here in the log.
Any ideas ?

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.
