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.
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 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.
I'm having problem to pass variable from a package to a another one. I having 2 packages: the parent (parent.dtsx) use a Execute Package Task to execute the child package (child.dtsx). In the parent package, I have a variable named var1 (data type String) with value=test In my child package, I having a script task using the variable var1 to make a MsgBox (var1 is in readonly in the script): MsgBox(CStr(Dts.Variables("var1").Value))
In this case, I having an error (cause the variable may no exist) but i can see the value of the variable in the MessageBox and the execute package task fail because of this error.
After I tried this solution: (Found in this Forum) In the child package, I create the variable var1 (same type, no value). Then in the control flow, I right click on the background and select "package configurations". I enable package configurations. Then I add a new one. I change the configuration type to "parent package variable." Then, in the specify configuration settings entry, I enter the name of the variable in the parent package. On the following screen, I select the "value" property of the variable created in this package (Child package). At last, I give the configuration a name and hit finish.
If I execute my parent package, the result is no value in the MessageBox.
I also tried the same thing (with the package configuration) to pass a a variable with the connection string from a package to the connection of an another one (I set the connection string of the connection) and it doesn't work.
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.
I have one package that executes 4 child packages (5 total). All 5 packages are set to log information using a connection string with a variable set at runtime for the location. The child packages use a parent variable to get the log connection string from the parent package.
The parent package logs fine, but a strange behavior occurs with the child packages.
The child packages all log data to the location used in the configuration file variable during runtime (like it's supposed to). However, I would get an error right before the first child package finishes execution saying path not found. Just for giggles, I created the folder I use in my development environment on the production environment. The error goes away, but the log file is created in that folder with no data in it. Subsequently, the log file with the data is created in the location set in the configuration file. Now I have two log files!!!!
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.
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.
We are using SSIS for the first time. My team is working on a project that involves putting a date time stamp into a series of tables. These tables are being assembled in a series of child packages being executed by the parent. When the parent runs, we evaluate our timestamp variable as a GETDATE() expression and pass it to the children to be included as a derived column. We don't want the actual runtime of each step to be the timestamp, just the start of the batch (parent).
In order to get the variable to pass over to the child, we needed to set the package location to "file system"instead of "SQL Server". It seems unusual that this would be so. Are we doing something wrong?
What implications does this have for deployment? Will we need to customize the packages for each instance we plan to run this on? Can you have a parent run a child package on a different instance? This would be a performance plus since we have really huge source databases and would like to distribute the processing.
Hmmm, my boss just told me to scratch the whole idea of parent-child and go with a control table to store the variable for all the packages to access. Oh well, I'm still interested in why this is so cumbersome when really its just passing a parameter from one procedure to another.
Oh, and I think you could use a spellchecker on this message box. At least I could use one.
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've created an SSIS package that uses parent package variables at several steps in the data flow. However, those parent package variables are only visible during runtime, making debugging the package practically impossible. Let me give you a simplified example:
In the parent package, I have a string variable named "sqlLookup" that looks like this:
"SELECT * from tblTest WHERE city = " + @city
Also in the parent package is a variable named "city" which I can set to the name of the city that I want to query on. This dynamically updates the sqlLookup variable, which is being evaluated as an expression.
In the child package, I have an OLE DB Source control which is using the "sqlLookup" variable for its query. I have set up my parent package variable configuration, and it works when I run the package.
The problem is this...when I open the child package, I get an error on the OLE DB Source control using the parent package variable, "Command text was not set for the command object". Presumably, this is because the parent package variable is only available during run-time, and not at design time. And, if metadata changes (which it has), I can't get into the OLE DB Source control to edit it, because it throws the error.
So, my question is this: are there any workarounds for this problem? Is there a better way to do this? This seems like such an obvious problem that I'm wondering if I either missed a step somewhere, or if I'm just doing it the wrong way.
when using lookup i am geting the following warning.our OLEDB connection is Oracle.how to resolve this will this have any performance impact.
[Lookup [14342]] Warning: Cannot retrieve the column code page info from the OLE DB provider. If the component supports the "DefaultCodePage" property, the code page from that property will be used. Change the value of the property if the current string code page values are incorrect. If the component does not support the property, the code page from the component's locale ID will be used.
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 everybody, I moved my packages to the new machine, and have problem with parent variables. When child package tries to get parent variable value I get an error:
Information: 0x40016042 at LoopPackage: The package is attempting to configure from the parent variable "MAIN_SesId".
Warning: 0x80012028 at LoopPackage: Process configuration failed to set the destination at the package path of "Package.Variables[User::MAIN_SesId].Properties[Value]". This occurs when attempting to set the destination property or variable fails. Check the destination property or variable.
I need to bring over a large number of tables' records (200+ tables) with the Import/Export Wizard. The tables are being imported from MS Access. A separate script run previously will create the tables, so the DTS wizard is only to bring over the data from the Access tables into the empty SQL ones.
First, I get the warning that indicates "a large number of tables are selected for copying, and the wizard may not be able to copy all the tables in a session. Select no to go back and unselect some tables, or select Yes to attempt to copy all the currently selected tables at one time".
Well, I proceed with the DTS and it tries to validate and takes a fair bit, but then it errors indicating:
"Error 0xc0202009: {2F0FABA0-5F4B-4310-97C0-76EA19893547}: An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft JET Database Engine" Hresult: 0x80004005 Description: "Unspecified error". (SQL Server Import and Export Wizard)"
Can anyone shed any light on why I receive an "unspecified error" when tring to DTS a larger number of tables. It does not error, if I import 40 or so tables.
Just a fair warning for you out there - be aware that if you are using a lot of SSIS intrinsic objects, tasks, components etc which you have used in hopes of reusability - when needing to upgrade or move packages to another location will suck.
Im just trying to move packages from one server to another - none of the packages which use components will work. For example I'm using Konesans Trash Destination - even after proper installation - package cannot find it. (Im real glad I only use 2 components in a few packages - all components will be now removed for sure)
That solidifies my impression that in order to use SSIS you really have to DUMB it down to only using SQL, Script & Data Flow (direct load data only).
I'm busy rewriting DTS packages as SSIS packages. As and when I finish a package I run it in debug mode via Microsoft Visual Studio and then examine the Exection Results to see the messages generated.
Now it may or may not matter how I run the package but the following warning has been generated :-
[SSIS.Pipeline] Warning: Warning: Could not open global shared memory to communicate with performance DLL; data flow performance counters are not available. To resolve, run this package as an administrator, or on the system's console.
I'm working on an SSIS package that uses a vb.net script to grab some XML from a webservice (I'd explain why I'm not using a web service task here, but I'd just get angry), and I wish to then assign the XML string to a package variable which then gets sent along to a DataFlow Task that contains an XML Source that points at said variable. when I copy the XML string into the variable value in the script, if do a quickwatch on the variable (as in Dts.Variable("MyXML").value) it looks as though the new value has been copied to the variable, but when I step out of that task and look at the package explorer the variable is its original value.
I think the problem is that the dataflow XML source has a lock on the variable and so the script task isn't affecting it. Does anyone have any experience with this kind of problem, or know a workaround?
I have a SQL Task that updates running totals on a record inserted using a Data Flow Task. The package runs without error, but the actual row does not calculate the running totals. I suspect that the inserted record is not committed until the package completes and the SQL Task is seeing the previous record as the current. Here is the code in the SQL Task:
DECLARE @DV INT; SET @DV = (SELECT MAX(DateValue) FROM tblTG); DECLARE @PV INT; SET @PV = @DV - 1;
I've not been successful in passing a SSIS global variable to a declared parameter, but is it possible to do this:
DECLARE @DV INT; SET @DV = ?; DECLARE @PV INT; SET @PV = @DV - 1;
I have almost 50 references to these parameters in the query so a substitution would be helpful.
I'm new to SSIS, but have been programming in SQL and ASP.Net for several years. In Visual Studio 2005 Team Edition I've created an SSIS that imports data from a flat file into the database. The original process worked, but did not check the creation date of the import file. I've been asked to add logic that will check that date and verify that it's more recent than a value stored in the database before the import process executes.
Here are the task steps.
[Execute SQL Task] - Run a stored procedure that checks to see if the import is running. If so, stop execution. Otherwise, proceed to the next step.
[Execute SQL Task] - Log an entry to a table indicating that the import has started.
[Script Task] - Get the create date for the current flat file via the reference provided in the file connection manager. Assign that date to a global value (FileCreateDate) and pass it to the next step. This works.
[Execute SQL Task] - Compare this file date with the last file create date in the database. This is where the process breaks. This step depends on 2 variables defined at a global level. The first is FileCreateDate, which gets set in step 3. The second is a global variable named IsNewFile. That variable needs to be set in this step based on what the stored procedure this step calls finds out on the database. Precedence constraints direct behavior to the next proper node according to the TRUE/FALSE setting of IsNewFile.
If IsNewFile is FALSE, direct the process to a step that enters a log entry to a table and conclude execution of the SSIS.
If IsNewFile is TRUE, proceed with the import. There are 5 other subsequent steps that follow this decision, but since those work they are not relevant to this post. Here is the stored procedure that Step 4 is calling. You can see that I experimented with using and not using the OUTPUT option. I really don't care if it returns the value as an OUTPUT or as a field in a recordset. All I care about is getting that value back from the stored procedure so this node in the decision tree can point the flow in the correct direction.
The SSIS package passes the FileCreateDate parameter to this procedure, which then compares that parameter with the date saved in tbl_ImportFileCreateDate.
If the date is newer (or if there is no date), it updates the field in that table and returns a TRUE IsNewFile bit value in a recordset.
Otherwise it returns a FALSE value in the IsNewFile column.
SELECT @CreateDateInTable = FileCreateDate FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName
IF EXISTS (SELECT ProcessName FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName)
BEGIN
-- The process exists in tbl_ImportFileCreateDate. Compare the create dates.
IF (@FileCreateDate > @CreateDateInTable)
BEGIN
-- This is a newer file date. Update the table and set @IsNewFile to TRUE.
UPDATE tbl_ImportFileCreateDate
SET FileCreateDate = @FileCreateDate
WHERE ProcessName = @ProcessName
SET @IsNewFile = 1
END
ELSE
BEGIN
-- The file date is the same or older.
SET @IsNewFile = 0
END
END
ELSE
BEGIN
-- This is a new process for tbl_ImportFileCreateDate. Add a record to that table and set @IsNewFile to TRUE.
INSERT INTO tbl_ImportFileCreateDate (ProcessName, FileCreateDate)
VALUES (@ProcessName, @FileCreateDate)
SET @IsNewFile = 1
END
SELECT @IsNewFile
The relevant Global Variables in the package are defined as follows: Name : Scope : Date Type : Value FileCreateDate : (Package Name) : DateType : 1/1/2000 IsNewFile : (Package Name) : Boolean : False
Setting the properties in the "Execute SQL Task Editor" has been the difficult part of this. Here are the settings.

I tried several SQL statements, suspecting it's a syntax issue. All of these failed, but with different error messages. These are the 2 most recent attempts based on posts I was able to locate.

When I run this in debug mode with this SQL statement ... exec ? = dbo.p_CheckImportFileCreateDate 'GL Account Import', ?, ? output ... the following error message appears.

When the above is run tbl_ImportFileCreateDate does not get updated, so it's failing at some point when calling the procedure.
When I run this in debug mode with this SQL statement ... exec p_CheckImportFileCreateDate 'GL Account Import', ?, ? output ... the tbl_ImportFileCreateDate table gets updated. So I know that data piece is working, but then it fails with the following message.

The IsNewFile global variable is scoped at the package level and has a Boolean data type, and the Output parameter in the stored procedure is defined as a Bit. So what gives?
The "Possible Failure Reasons" message is so generic that it's been useless to me. And I've been unable to find any examples online that explain how to do what I'm attempting. This would seem to be a very common task. My suspicion is that one or more of the settings in that Execute SQL Task node is bad. Or that there is some cryptic, undocumented reason that this is failing.
Supose I have two records in a parent-child relationsuip (actually I have many more such records). Does SSIS offer any support ask for inserting one record into the parent table, the other into the child table, and updating the foreign key of the child to point to the parent?
TIA,
Barkingdog
P.S. I have to do just this as part of the datawarehouse test I'm running. Seems like a common task but I don't recall anything in SSIS addressing the issue.
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 have set up an FTP connection that tests successfully. I can log on to the FTP site with the same credentials and see my root folder, and within that, two more folders. In my FTP task, I want to receive files to my local machine. The problem is that the only remote path available is not at the root level, and the only thing I can see are files from one of the child folders, but not the child folder I want.
Is it possible in the remote path to change folders? The remote path just shows a "/", which I thought would be the root level, but it is somehow linked to a child folder.I've tried various combinations to get to the folder I want, /root folder/child folder, but that gives the error that the folder does not exist.
If I open the FTP Task Editor, click on File Transfer, and click the ellipses for the Remote Path, the Browse For File box opens, with a "/" in the Location section, and a list of files in the child folder that I do not want to be in. If I click the "Up Directory" button, I get the message "Already at top level directory".
how I can get the files from one particular folder on the FTP site?
I have the below query which in turn goes in the where clause
Code:
SELECT CASE WHEN EXISTS (SELECT child.id FROM InspectionType parent, InspectionType child WHERE parent.id = child.parentId AND parent.code = 'INSPECTION_TYPE_SAFETY_LIFE' AND parent.zoneId = 10129) THEN (SELECT child.id FROM InspectionType parent, InspectionType child WHERE parent.id = child.parentId AND parent.code ='INSPECTION_TYPE_SAFETY_LIFE' AND parent.zoneId = 10129) ELSE (SELECT id FROM InspectionType WHERE code = 'INSPECTION_TYPE_SAFETY_LIFE' AND zoneId = 10129) END
I am getting below error
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
I tried to solve this problem with If and else but it is not going well with in-clause
Code: select * from InspectionType where id in (select IF EXISTS (SELECT child.id FROM InspectionType parent, InspectionType child WHERE parent.id = child.parentId AND parent.code = 'INSPECTION_TYPE_SAFETY_LIFE' AND parent.zoneId = 10129) BEGIN (SELECT child.id FROM InspectionType parent, InspectionType child WHERE parent.id = child.parentId AND parent.code ='INSPECTION_TYPE_SAFETY_LIFE' AND parent.zoneId = 10129) END ELSE (SELECT id FROM InspectionType WHERE code = 'INSPECTION_TYPE_SAFETY_LIFE' AND zoneId = 10129) )
I am using select * from InspectionType where id in() for illustation only. The sub-query results will go another query
Code: SELECT child.id FROM InspectionType parent, InspectionType child WHERE parent.id = child.parentId AND parent.code ='INSPECTION_TYPE_SAFETY_LIFE' AND parent.zoneId = 10129
This returns more than one row.I know why is the error message but need to achieve this functionality.
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...
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 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.
Newbie question. I'm new to using variables in SSIS. Are there any good examples around of how to return an @@identity value from a procedure and then use it globally within an SSIS package for multiple "execute SQL" tasks? I've gone though the documentation but don't find it to be very complete.
hi, I have one variable at package level in ssis. I want to use this in sql statement of execute sql task. but i m not able to find how to do this. my sql statement is select * from Var
where Var is variable at package level which is string.
