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.
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
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 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.
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 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...

1. to display all parent with ORDER BY ItemOrder (no need to sort by ItemDate) 2. display all child row right after their parent (ORDER BY ItemOrder if ItemDate are same, else ORDER BY ItemDate) 3. display all grand child row right after their parent (ORDER BY ItemOrder if ItemDate are same, else ORDER BY ItemDate)
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.
I searched for an answer for this, and found a few good threads, but none of them seem to be doing quite the same thing I'm trying to do.
I have two packages, parent and child. Parent does basic file manipulation -- encrypting/decrypting, moving from server to server, backing up to archive, pulling/pushing to external server via FTP, etc. It is completely dumb to what child does. Child is the guts of the data work -- the ETL package.
The goal is to have this one parent package be used by several ETL child packages. But not only can parent use different children (depending on which config is used when executing parent), but child can also handle different tasks, depending on a configuration it uses.
Let me break it down further.
Three packages:
ParentPackage - Used by all jobs ChildPackage1 - Used for processing orders ChildPackage2 - Used for processing inventory
Four configurations (thus four jobs):
Job1Configuration - Used for processing orders for ClientA Job2Configuration - Used for processing orders for ClientB Job3Configuration - Used for processing inventory for ClientA Job4Configuration - Used for processing inventory for ClientB
Job1Configuration is set up to tell ParentPackage to use ChildPackage1, and to provide ChildPackage1 w/ various data for ClientA -- and so forth.
To my understanding, there is no passthrough of the config data from parent to child. A child package doesn't "inherit" or otherwise receive the information from the parent package, unless explicit variables are set up. This won't work for us, because ParentPackage is dumb of any data that the child packages may need. In other words, we don't want to set up ParentPacakge with every possible variable that every child package may need.
Also, I'm not aware of a way of setting up a job to provide a child package directly w/ a package configuration.
Is there any way to do what I'm trying to accomplish?
If I didn't explain something clearly, let me know and I will try to clarify.
I was hoping someone might be able to clarify how configuartions work with child packages. My process has 3 levels of packages. The main packages called two child packages each of which calls more child packages.
I'm using Configurations to pass variables from parent packages to child packages. But each level of packages contains Data Flow Source/Destination connections. I was planning on having only 1 XML Configuration file in the main package that would allow the data connections for the main package to be configured for the target enviornment. When the job is scheduled I will be able to point a configuration file for use with the main packages. But will that configuration file be applied to all child packages that will run? All of the Connections Managers have the same name so I'd like to make the change in one file.
If not, am I forced to define a parent/child variable to pass the Connection String from the parent to each of the child packages? Use an expression to set the Connection String dynamically? This seems like a lot of extra work, so I'd really like to see if there is a way to do it with an XML configuration file. Even if I have to definte the same config file for each of my 20+ packages.
hi, i have two tables i want the identity value of the parent table to be inserted into the chile table here is my code,but i don't know why it isn't working ! protected void Button1_Click(object sender, EventArgs e) { string connectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString; string pcontent = TextBox1.Text; string data = TextBox2.Text; addtopic(pcontent,connectionString); addfile(data, connectionString); } public void addtopic(string subject,string connstring) { using (SqlConnection connection = new SqlConnection(connstring)) { SqlCommand command = new SqlCommand("INSERT INTO parent" + "(content)" + "Values(@content)", connection); command.Parameters.Add("@content", SqlDbType.Text).Value = subject; connection.Open(); command.ExecuteNonQuery(); } } public void addchild(string name, string connstring) { using (SqlConnection connection = new SqlConnection(connstring)) {Guid id = Guid.NewGuid(); SqlCommand commandd = new SqlCommand("INSERT INTO child" + "(parentid,data,uniqueid)" + "Values(@@IDENTITY,@data,@uid)", connection); commandd.Parameters.Add("@data", SqlDbType.NVarChar, 50).Value = name; commandd.Parameters.Add("@uid", SqlDbType.UniqueIdentifier).Value = id;
I have a parent/child relationship in a relational database broken out like this: Table Name: categories[category_id] int (primary_key NOT NULL),[category_name] varchar(50),[parent_fk] int The parent references the category_id in the same table to create the parent/child relationships. I can get all the bottom level categories by doing this: select category_id, category, parent_fk from categories where category_id not in ( select parent_fk from categories) Each bottom-level category has a count attached to it. The problem I have is getting the counts rolled up for each parent of the bottom level. A parent could/will have multiple bottom-level categories (and counts). My sql is a little weak, could you help me out? I can utilize everying in SQL 2000 (stored proc, UDF, anything). Thanks!
I want to find all the child of a node in a tree . A child can have multiple parent i.e 2 can be place under multiple parent . The folling is the data:
This structure requires complicated queries (recursive call) to find out all the child of a root node, so I have added another field for the root id. Is this a good relational database design ? kindly suggest.
In our database we have a list of devices in a "Device" Table, eachhaving one or more IP's located in the "IP" Table linked through aforein key on the DeviceID Column.I would like to retrieve this information as SuchDeviceID IpAddress1 10.0.0.1, 10.0.0.2, 10.0.0.32 ...345etc.Is it possible to do that without using cursors? Through a query?
Hello all, I'm having a real hard time trying to figure this one out. I'm trying to create a sql query that selects both the parent name and it's children, but it's got to loop through all the record sets to populate a drop down as an end result.
I think I thought this out correctly: I have 2 tables
category relationship
tbl category cat_id //auto int cat_name // varchar
relationship r_id // auto int parent_id // int child_id // int
both the parent_id and child_id are associated with the cat_id in my category table I could have 1cars // this is parent 2 audi 3 bmw 4 chevy
Table data example
r_id parent_id child_id **************************** 1 1 15 2 1 16 3 1 17 4 2 55 5 2 56 etc... I want to select both the parent cat_name from category and also select the child cat_name where the parent_id = #
I can do it manaully like this select cat_name, cat_id, parent_id , child_id from category, relationships where child_id = cat_id and parent_id = 1
what is the best way to loop through all the parent ids to find child category? Could this be done in a stored procedure?
I am having problems creating a trigger in SQL Server? I have 2 tables (parent and child) with one to many relationship. When I save a record, one row gets inserted in the parent and one to many gets inserted in the child. The trigger is on the parent table and it is trying to select the number of new records just inserted in the child table that meets a certain criteria. Since the transaction hasn't been committed I can not select the number of records from the child. Does anyone know how to handle this? My manager insists this be done in a trigger. Thanks, James

Then I would like to be able to query against this view with something like this:
SELECT * FROM FamilyView Where Child2 = 'Peter'
I have no idea how to write the SQL for this View. Is it possible? Is this possible without using a cursor?
Below is my sample data of my table named "Groups"
Code: with Groups as ( select 1 as GroupId,'Oracle' as GroupName,0 as IdParentGroup union all select 2 as GroupId,'Microsoft' as GroupName,0 as IdParentGroup union all select 3 as GroupId,'IBM' as GroupName,0 as IdParentGroup union all select 4 as GroupId,'SunMicrosystem' as GroupName,1 as IdParentGroup union all select 5 as GroupId,'peoplesoft' as GroupName,1 as IdParentGroup union all select 6 as GroupId,'mysql' as GroupName,1 as IdParentGroup union all select 7 as GroupId,'Nokia' as GroupName,2 as IdParentGroup union all select 8 as GroupId,'EShop' as GroupName,2 as IdParentGroup union all select 9 as GroupId,'Meiosys' as GroupName,3 as IdParentGroup union all select 10 as GroupId,'UrbanCode' as GroupName,3 as IdParentGroup ) select * from groups;
Expected result:
Code: with ExpectedResult as ( select 'Oracle' as GroupName,'SunMicrosystem' as SubGroup union all select '' as GroupName,'peoplesoft' as SubGroup union all select '' as GroupName,'mysql' as SubGroup union all select 'Microsoft' as GroupName,'Nokia' as SubGroup union all select '' as GroupName,'EShop' as SubGroup union all select 'IBM' as GroupName,'Meiosys' as SubGroup union all select '' as GroupName,'UrbanCode' as SubGroup ) select * from ExpectedResult;
some sample query to how to achieve this parent-child has the same table.
I'm an entre level junior programmer. My question is kind of confusing but I'll try to put it as simple as I can.
First we have a main table called "job1". This table consists the order information. The file_id is the unique id and the primary key for this table. This table also pertains other information such as customer data (max limit 5), job data etc. This table is actively (non-stop) used throughout the day.
We have a non-interactive process which will take customers information from the main table and insert into the child table table "jobcust". Jobcust would have file_id, cust, cust_type. For example, if Job1 table had fiel_id=100 and cust1="Tom" and Cust2="David", now Jobcust will have two records file_id, cust1 and file_id,cust2. The main problem is the child table needs to be updated right away and our non-interactive process is good at doing that.. but it is causing a major DATA LATENCY. I would like to ask you all, if you know any better way of doing this without any process.. like in the back end with a trigger/procedure or something like that.
I am importing data from a paradox table and trying to clean it up. I have this query that finds all the child records that are not in the parent table.
Select MemberID FROM memtype AS a WHERE NOT EXISTS (SELECT * FROM members AS b WHERE a.MemberID IN (b.MemberID));
Now I'm trying to delete all those child records instead of just selecting them so I tried...
Delete MemberID FROM memtype AS a WHERE NOT EXISTS (SELECT * FROM members AS b WHERE a.MemberID IN (b.MemberID));
I have a parts table which has partid (GUID) column and parentpartId (GUID) column. Need to copy the records to the same table with new GUIDs for partids. How to do that? cursor or temp tables?
I have an application that has an existing query which returns org units (parent and child) from organization table with orderby on createddate + orgid combination.
Also I added another log table Organization_log with exact columns as Organization table and additional 'IS_DELETED' bool column.
WITH Org_TREE AS ( SELECT *, null as 'IS_DELETED', convert (varchar(4000), convert(varchar(30),CREATED_DT,126) + Org_Id) theorderby FROM Organization WHERE PARENT_Org_ID IS NULL and case_ID='43333'
[code]...
I need to modify the query:
1. To display the records both from the Organization table and Organization_Log table. 2. The orderby should be sorted on 'Organization Name' asc and it should follow the child order in alpha sort as well.
I am wondering if there is a way to insert one parent record with multi child records in one transaction? I am using dataset to update my database. I want to use transaction so if one record insert fails all the transctions rollback.
I think I might know the answer to this, but I wanted to see if any one has come up with a slick idea for enforcing this relationship. If I have two tables and one is dependent on the other (parent-child relationship), how can I enforce that every parent record has a corresponding child record? Here is a code example
USE tempdb
GO
CREATE TABLE dbo.Parent ( ParentId int NOT NULL )
ALTER TABLE dbo.Parent ADD CONSTRAINT PK_Parent PRIMARY KEY CLUSTERED (ParentId)
CREATE TABLE dbo.Child ( ParentId int NOT NULL ,ChildId int NOT NULL )
INSERT INTO dbo.Parent VALUES (1) INSERT INTO dbo.Child VALUES (1,1) INSERT INTO dbo.Parent VALUES (2) INSERT INTO dbo.Child VALUES (2,2) INSERT INTO dbo.Child VALUES (2,1) INSERT INTO dbo.Parent VALUES (3)
SELECT p.ParentId, 'I SHOULD HAVE A DEPENDENT RECORD' FROM dbo.Parent p LEFT JOIN dbo.Child c ON p.ParentId = c.ParentId WHERE c.ParentId IS NULL
ParentId 3 should have a child record associated with it. I am assuming that these are my choices:
1) code all inserts to the parent table along with a insert to the child table and wrap those in a transaction
2) place a trigger for insert on the parent table that ensures that the child table is populated after data for the parent.
Here is the gotcha, we will be using a middle-tier data access layer (nhibernate or dlink) so .NET application developers will be creating the data modifications at the transactional level. Also there might be several ongoing ETLs that populate this schema as well, so multiple points of entry and seperate code blocks. I don't want to hide business logic within triggers.
I assume that all our coders are competent and could enforce this properly via code, but I know that mistakes happen. Has any one come across this situation and have a solution for enforcing the integrity of the schema with constraints?
how can we delete parent table as well as child table using a single query applied on parent table, can someone please help me onn this topic? it will be very nice of you guys.
