Creating A Parameter File For The Data Flow Tasks ??? VerY Urgent
Jan 2, 2008
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 !!!

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

I have a table that holds in each record an image (varbinary(max) actually), a text reference for the image and a MIME type for the image. I need to read this table and for each record that has been created since the last run, I need to create a file with the image as the content, the mime type as the file extension and the text reference as the file name. There will be one file created per record found by the data flow source.
I was assuming that I could use the flat file destination and manipulate the file naming using the contents of each record in the flow but am completely stumped on how to achieve this.
Does anyone have any ideas?
thanks

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:
TITLE: Microsoft Visual Studio
------------------------------
Failed to create the task.
------------------------------
ADDITIONAL INFORMATION:
The designer could not be initialized. Microsoft.DataTransformationServices.Design)
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?

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 doesnt have anything for mapping parameter.
Thanks in Advance

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?

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.
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.
The problem is that SSIS says.
"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"
((Microsoft.DataTransformationsServices.Controls) "<v:shapetype coordsize="21600,21600" filled="f" id="_x0000_t75" o:preferrelative="t" o:spt="75"
path="m@4@5l@4@11@9@11@9@5xe" stroked="f">

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.

Hi 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

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

Hi all,
In a foreachloop, I am inserting records into a flat file which is working fine. But the thing is that as the file grows, it takes longer for it to locate the EOF(End of File) of the flat file so as to insert the records.
I have around 70-100 lines written to the file at each loop and there are more than 20k records to be looped. wihich means that at the end I should be having 1400k - 20000k line in the text file.
One solution would be to insert the records at the start of the file itself so that it does not has to lookup the EOF each time before writting.
Another would be to generate separate files and then merge it.
Any idea how can this can be done?
Beside this I have to zip the file and then SFTP to a given address.
Any suggestion or help would be welcome.

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)?

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

any suggestions on dealing with a flat file in the format below. I only want to process the data columns in the middle of the file and want to ignore all other rows. This was a very simple task in DTS with a small amount of VBScript in the transformation but it doesn't seem as straightforward in SSIS. thanks
......... file example ......
start-of-file
header1
header2
...
start-of-data
col0|col1|col2|col3|....
col0|col1|col2|col3|....
col0|col1|col2|col3|....
end-of-data

In DTS 2000 I had a situation where I had a text file as input source and text file as output source. On migrating the package to 2005 it puts a wrapper around it which executes it as a 2000 package, the rest of the tasks are neatly converted to 2005 style tasks. I presume this to mean that this will not be supported through to the next version, and there is no direct equivalent in 2005.
My question is how do I import a non-flat file source which has different numbers of columns per line. I did ,somehow, manage to do this with 2000 but cannot seem to get anywhere with 2005.
The flat file source seems to be expecting a common number of columns and just can't seem to cope with no column delimiters on some lines. If anybody knows different I would be glad to hear about it.
Raw data is not helpful to me as only works with a specific raw type (apparently)
Went onto Bulk Insert Task but got this message
[Bulk Insert Task] Error: An error occurred with the following error message: "Cannot fetch a row from OLE DB provider "BULK" for linked server "(null)".The OLE DB provider "BULK" for linked server "(null)" reported an error. The provider did not give any information about the error.Bulk load: An unexpected end of file was encountered in the data file.".
Have already browsed with this on web but only find comments about changing timeout setting.
Can find timeout settings in DataFlow source and DataFlow destinations but not in Bulk Insert Task.
As you can see this is a long and protracted question.
If the answer is simple I apologise if not blame Microsoft. Other than that have found SSIS has some nice improvements, apart from the odd vague error message I keep coming across.

For a database, we have 4 data files in a particular file group and the file sizes are almost 70 GB each.
Do I come across any performance issues if I create/pre-allocate an additional data file in the same file group so that the existing files don't grow too much?

All,
I'm having an issue with the Flat File Data Flow Source returning only a limited set of the rows that are in the flat file. Basically, I connect to the flat file fine, it goes to retrieve the data (tab delimited file) and only returns 190 of 392 rows. Is there a limitation on the # of rows this data flow source can retrieve or something? I've look all through the settings and properties of the task as well as the connection manager and nothing is obvious as to what is causing this. Hopefully someone ou tthere has run into this before and can help me retrieve all rows. Thanks in advance!

I have a Data Flow Task within a ForEach loop container. The source of the flow is ADO.NET connection and the destination is a Flat File Connection. I loop through a collection of strings in the ForEach loop. Based on the string content, I write some data to the same destination file in each iteration overwriting the previous version. I am running into following Errors:
[Flat File Destination [38]] Warning: The process cannot access the file because it is being used by another process.
[Flat File Destination [38]] Error: Cannot open the datafile "Example.csv".
[SSIS.Pipeline] Error: Flat File Destination failed the pre-execute phase and returned error code 0xC020200E.
I know what's happening but I don't know how to fix it. The first time through the ForEach loop, the destination file is updated. The second time is when this error pops up. I think it's because the first iteration is not closing the destination file. How do I force a close of the file within Data Flow task or through a subsequent Script Task.This works within a SQL 2008 package on one server but not within SQL 2012 package on a different server.
