Dear All!
My package has a Data Flow Task. In Data Flow Task, I use a Script Component and a OLE BD Destination to transform data from txt file to database.
Within Data Flow Task, I want to call File System Task to move file to a folder or any Task of "Control Flow" Tab. So, Does SSIS support this task? Please show me if any
Thanks
Hi, All,
I need to pass a parameter from control flow to data flow. The data flow will use this parameter to get data from a Oracle source.
I have an Execute SQL task in control flow to assign value to the Parameter, next step is a data flow which will need take a parameter in the SQL statement to query the Oracle source,
The SQL Looks like this:
select * from ccst_acctsys_account
where to_char(LAST_MODIFIED_DATE, 'YYYYMMDD') >?
THe problem is the OLE DB source Edit doesn€™t have anything for mapping parameter.
Thanks in Advance
I have an Execute SQL Task that returns a Full Rowset from a SQL Server table and assigns it to a variable objRecs. I connect that to a foreach container with an ADO enumerator using objRecs variable and Rows in first table mode. I defined variables and mapped them to the columns.
I tested this by placing a Script task inside the foreach container and displaying the variables in a messagebox.
Now, for each row, I want to write a record to an MS Access table and then update a column back in the original SQL Server table where I retreived data in the Execute SQL task (i have the primary key). If I drop a Data Flow Task inside my foreach container, how do I pass the variables as input to an OLE DB Destination on the Data Flow?
Also, how would I update the original source table where source.id = objRects.id?
Thank you for your assistance. I have spent the day trying to figure this out (and thought it would be simple), but I am just not getting SSIS. Sorry if this has been covered.
Thanks,
Steve
Hi everyone,
Primary platform is 64 bit cluster.
How to move information allocated in SSIS variables from Data Flow to Control Flow layers??
We've got a SSIS package which load a value into a variable inside a Data Flow. Going back to Control Flow how could we retrive that value again????
Thanks in advance and regards,
I'm currently setting variables at the package level with an ExecuteSQL task. This works fine. However, I'm now starting to think about restartability midway through a package. It would be nice to have the variable(s) needed in a data flow set within the data flow so that I only have to restart that task.
Is there a way to do that using an SQL statement as the source of the value in a data flow?
OR, when using checkpoints will it save variable settings so that they are available when the package is restarted? This would make my issue a moot point.
Hi all! I recently started working with SSIS and one of the things that is puzzling me the most is what's the best way to go:
A small control flow, with large data flow tasks
A control flow with more, but smaller, data flow tasksAny help will be greatly appreciated.
Thanks,
Ricardo
Greetings,
I have a question about the best method to ensure the proper flow of control within a package. I have three related SQL tasks €“ A, B, and C €“ that must execute in sequence. If any one of the tasks fails then the remaining tasks should not execute because each is dependent on the previous step. (A €śsuccess€? precendence constraint.)
Likewise, I have a second set of SQL tasks €“ 1, 2, and 3 €“ that must execute in sequence. Task 3 should never execute unless tasks 1 and 2 have been successful.
I consider these to be two independent logic paths in the same package and, indeed, when I run the package both task A and task 1 begin running at the same time.
What I€™m not sure of is how to add a new task €“ Z €“ that will execute only after both the A-B-C and 1-2-3 task paths have completed. Diagramatically, this would be like having a €ścompletion€? constraint linking task C to task Z and another €ścompletion €ś constraint linking task 3 to task Z. In other words, the two independent paths merge at task Z. Task Z is an audit step that must always run €“ it emails summaries of the database activities performed by the other tasks.
What has me puzzled is how I get to Z when there is a failure in either the A-B-C path or the 1-2-3 path. As things stand now, the package will never reach task Z if there is a failure in an earlier task because they are joined by a €śsuccess€? constraint.
I thought I could get around this by using a €śsequence container€? but I discovered when I added A, B, and C to a container that I couldn€™t use the €śsuccess€? constraint I needed. I was just guessing that this might be the way to do it.
Can anyone help me with a best practice approach to the control flow issue I face? I€™m new if that isn€™t apparent by my question, so don€™t be afraid to make your answer simple and plain.
Thanks for any help,

I want to get the start time of data load and end time after data load and store it in a table which has mapping_id , mapping_name,start_time,end_time.
i use ActiveXScript task to get the start time before data load and store the mapping_id in a global variable,then data flow transformation occurs.
i want to use a global variable to store the mapping id ,so that i can update the end time after data load with that variable.how to do this?
is there any other way, i can get the start and end time of data load (other than the logging information)?
When I copy over an SSIS package I have been developing from my laptop to my desktop with Windows File Sharing (shared folders) across a home network, the moved package fails to load properly. I can see the Control Flow tasks but not the Data Flow tasks - they simply disappear! I have update the Connection Managers to point to the new machine, and tested them (OK).
Its the same as this issue posted here
And Here
Creating an empty package and clicking to create a new data flow cause this error:

Seems the only way is to uninstall and reinstall Client Components.
How do I uninstall and reinstall Client Components? when I try to do that, SQL Server Setup tells me "None of the selected features can be installed or upgraded. Setup cannot procees since there is no effective change being made to the machine...."
I had selected "Workstation components, Books online and Development tools". This is already installed - so how I can reinstall it if I get this message above which does not let me proceed.
Hello,
I have created around 10 seperate packages for our application data load. Now I am planning to create a master package (or a wrapper package) which will execute all the 10 packages (thru execute package task). Then I have a job which executes the master package at a given date and time.
Question : How can I enable / disable execution of each package within the master package depending upon a flag variable. The reason why I need this mechanism is if the flag = 0 then I don't want all 10 packages within master package to execute and if flag = 1 then master package execution should begin and subsequently execute all packages within that master package.
Thank you

Hi guys,
i got a foreach loop that has about 20 data flow tasks(same database connections but different extractions) but i notice that when i execute the project it only runs 4 data flow tasks at a time.
i know that there is an option for each data flow to set the "Engine Threads", but is there a way to set the thereads in a foreach loop or for the whole project so it will execute all data flow tasks in one go for each loop.
please help???
Hi guys,
i have a for each loop and it has about 20 data flow tasks (simple data extractions). i notice when i run the package it only runs up to 4 data flow tasks at a time. others have to wait till one of the first 4 flows finishes.
i was wondering if there's a way to change the limit of how many data flow tasks can run at a time. is there a property some where ?
i know this will be stressfull to the server, but the server is well equiped with CPU power and memory, so performance will not be an issue.
any thoughts?
Hey all, is there any explanation why just opening a data flow task causes a VSS check out?
The issue with this is that I have multiple developers, and when one wants to look at a data flow task in a package already checked out, it generates multiple VS errors.
Not big on the priority list, (not as big as the modal dialog issue) but still a pain.
Thanks!

What are the advantages and disadvantages of having multiple data flow tasks in one SSIS package?
Is this a good idea at all considering the workflow may be similar now but may change in the future? Should it be left as one data flow per package?
Hi,
I need to parameterize some values in the data flow so that i can chnage the values directly in parameter file and re run the data flow for new value in the passed in the parameter. This can be easy for other who do not know about the flow of data flow task as to where to change the variable/parameter.
How can this be accomplished. I want the data flow task to refer to this file before it starts executing and pick the appropriate value from the file.
Or is their any better way to accompalish what i want to do here in SSIS.???
tHNAKS FOR UR HELP FOLKS !!!
I have a requirement to read an encrypted file as a data source. I am not allowed to save an unencrypted text file version on disc at any time for any length of time, therefore I created a custom source component that reads an encrypted csv file, decrypts it, and then passes each row of data to the pipeline and ultimately to an ole data destination. Basically it is just a text file reader with an added class that adds functionality that decrypts the file before the component sets columns or reads rows.Â
The custom component, “Encrypted File Source”, has a custom property “encryptionkey” with the encryption required flag set to true (code below) and is declared as eligible to be set in the expressions.
IDTSCustomProperty100 EncryptionKey = ComponentMetaData.CustomPropertyCollection.New();
           EncryptionKey.Name =
"EncryptionKey";
           EncryptionKey.Description =
"Secure String key value to decrypt the file";
           EncryptionKey.Value =
string.Empty;
            EncryptionKey.ExpressionType =
DTSCustomPropertyExpressionType.CPET_NOTIFY;
           EncryptionKey.EncryptionRequired =
true;
I want to be able to set the password for the encrypted file in the SQL Agent job that executes the SSIS project. This means I have an environment with a variable, “DataPassword”, that is set to sensitive. It maps to a Project parameter in the SQL Agent job that is also set to sensitive. And I now I want to access that sensitive Project Password inside my data flow, specifically in the Encrypted File source task that I created and set my EncryptionKey to that Project Parameter.Â
The problem is that SSIS says.Â
"expression cannot be evaluated. ... The Expression will not be evaluated because it contains sensitive parameter value "$Project::DataFilePassord" . Verify that the expression is used properly and that it portects sensitive information"

HI All,
In several threads there has been discussion regarding adding connection managers to a package's data flow, etc. My challenge is that I have a large solution that contains many packages, and I need to change the connection manager linked to the data flow in all of the packages. When the solution was initially designed, data sources were used, and it has become a tedious maintenance issue to keep those in sync. We want to use a standard OLEDB connection manager, but adding a connection manager to each package and editing the corresponding data flow tasks in each package to use that new connection manager is a daunting task. I've coded a .Net module to access the packages, remove the old connection manager (data source) and add the new OLEDB data source. However, as I traverse the objects in the package hierarchy, when I come to the data flow object, the innerobject is not a dts object, but rather a _com object.. I can't seem to find any documentation/examples as to how to iterate the tasks within a data flow and change the connection manager. If you have any information, that would be quite helpful. If you reply with a code sample, if you would be so kind as to relate it to one of the sample packages provided with SSIS so I can run it, that would be great.
Thank you.
Steve.
Suppose if I have a “Foreach Loop Container” that iterates over a list. Is it possible to execute different data flow tasks based on the input?
Example : List contains elements L1, L2 & L3.
ForEach Loop Container checks the input. If its L1 then it should execute DF Task1, If L2 then execute
DF Task2 and similarly for L3.
Is it possible to achieve this?
Hi,
How do I retrieve the connections (connection managers) collections from Custom Data Flow destination? ComponentMetadata.RuntimeConnectionCollection is empty. I would like to be able to access all the connections defined in the package from the custom data flow task.
I came across code in which it was possible to access the Connections collection using the IDtsConnectionService for custom task (destination). The custom task has access to serviceProvider, whcih can be used to get access to the IDtsConnectionService interface but not the custom data flow task.
Any help appreciated.
Thanks

Hello,
Is it possible to use existing data flow components (Merge Join, aggregation,...) in a custom data flow component?
Thanks,

Is it possible to do? I'm getting lock violations in I try to execute several tasks in parallel.
View 4 Replies View RelatedHi Guys,
I have yet another question. How can i pass data b/w 2 data flow tasks? I'm trying to get some data from one sql server and then I want to pass this whole bunch of data to another data flow task which is going to get some data from second sql server. I would probably combine them using union all and then save that as a transaction in a third sql server?
Information regarding how to pass the data with some detailed discussion would be fine with me.
thanks

I recently upgraded to on 2012 SP1 CU5 and have found the SSDT gui for SSIS to be almost unusable. I can't drag or resize items. Any time i try they either automagically shrink to the tiniest possible size, shoot off to some extreme or just shake uncontrollably I didn't have these problems on previous versions (dont remember what It was).
Is there a fix for this?
I am new to SSIS can anyone tell me the diff between control flow and dataflow. if all the transformation are done using dataflow than why do we use control flow. Sorry if I am asking you very basic question.
Hi folks,
I have come across a situation where there 10 tasks. The second task on the flow is a script task which disables all further tasks based on a condition. I thought that the logic would be better if we force terminate the package successfully at this stage itself. How can this be done.
Thanks

Hi,
I'm trying to implement an incremental data pull (Oracle to SQL) based on Andy's blog:
http://sqlblog.com/blogs/andy_leonard/archive/2007/07/09/ssis-design-pattern-incremental-loads.aspx
My development machine is decent: 1.86 GHz, Intel core 2 CPU, 3 GB of RAM.
However it seems the data flow task gets hung whenever I test the package against the ~6 million row source, as can be seen from these screenshots. I have no memory limitations on the lookup transformation. After the rows have been cached nothing happens. Memory for the dtsdebug process hovers around 1.8 GB and it uses 1-6 percent of CPU resources continuously. I am not using fast load to insert new records into my sql target table. (I am right clicking Sequence Container 3 and executing this container NOT the entire package in the screenshots)

The weird thing is it only takes 24 minutes for a full refresh of the entire source table from Oracle to the SQL target table.
Any hints,advice would be appreciated.
I would like to be able to have a "while" statement execute until all af the rows in a temporary table have be processed.
I know I can do this with counters.
However, I was wondering if anyone knows of a SQL equivalent of
"WHILE NOT EOF" as in "do this until you hit the end of the table".
Thanks in advance for any input.
I am having a hard time with what appears to be something simple. I want to import an excel spreadsheet into a table on a daily basis from a command line. I created a package from the Import Wizzard in the SQL Management Studio and saved it. Since I want a clean table each day, my process needs to be create a temp table, import from the Excel file into the temp table. If that is successful, delete the original table and rename the temp table the original name. The point of this process is to provide for a fail-safe if there is some unforseen problem downloading the data on a particular day.
When I run the package, the first thing it does is delete the original table. I know this because the process shows the time that it finished is before anything else has started or finished. The time shown for the completion of the data flow task is about 2 minutes after that time.
This is maddening!!! The one thing I do not want to happen I can not seem to prevent. I have my control flow set on success. Why does it do this?
Is it possible to setup a Control Flow at the solution level rather than at the package level? I'd like to setup a Control Flow that truncates multiple tables in a staging database then runs multiple packages that reloads those tables. Each package has a Control Flow tab that seems to be specific to the package. Is it possible to set something up that governs the execution of multiple packages?
Thanks.
I'm writing my first serious stored procedure.
Essentially I have an incoming file, each line in the file is a record.
The records share the same initial key fields for the first 10 columns, then the field structure varies depending on a rectype and sequence number.
My initial plan was load the keys into fields, and load the remaining data into a long varchar field.
Then the stored procedure would evaluate the Rectype and Seqno of each record and chop up the Varchar accordingly.
So I set up a cursor to read the temporary table, do a fetch into variables, and go to evaluate the variables.
I want to be able to use a CASE statement to evaluate the fields and then perform various logic, but it's giving me fits because it seems like CASE only really works in Select statements, and won't really allow you to do any sort of GOTO logic.
I chopped the following SQL up and put in a rough cut of what I thought I was doing.

Hi,
I would like to have a decision maker component in Control Flow to decide which Data Flow to run.
For example:
if myVar=A then run data flowA
if myVar=B then run data flowB
......
We have Conditional Split component available in data flow but not in Control Flow. What component in control flow can be used to do the same job that conditional flow is doing in data flow? Or what's a work around for this.
Thanks in advance.
I have a problem when using nested loops in my Control Flow. The package contains an outer Foreach Loop using the Foreach File Enumerator which in my test case will loop over two files found in a directory. Inside this loop is another Foreach Loop using the Foreach Nodelist Enumerator. Before entering the inner loop a variable, xpath, is set to a value that depends on the current file, i e /file[name = '@CurrentFileName']/content. The Nodelist Enumerator is set to use this variable as its OuterXPATHString. Now, this is what happens:
First Iteration:
The first file is found and the value of xpath = /file[name = 'test1.txt']/content. When the inner loop is entered it iterates over the content elements under the file with name test1.txt as expected.
Second Iteration:
The second file is found and the value of xpath = /file[name = 'test2.txt']/content. When the inner loop is entered it unexpectedly still iterates over the content elements under the file with name test1.txt.
My question is: Should it not be possible to change the loop condition of an inner loop in an outer loop such that the next time it is entered it will be done based on the new condition? It seems that the xpath variable is read once, the first time, and never again. If that is the case, does anyone know of a workaround?
