I'm not exactly sure how to ask this question ... but here goes!!
I want to get an idea of how SSIS actually executes transformation tasks.
Do transformation tasks (eg a lookup) complie down to managed code or are the executed as SQL commands in a SQL server database?
Thanks.
Hi
I have migrated a DTS that had some activeX transformation tasks within data pump flow tasks.
Those parts were migrated as "DTS 2000 tasks" .. so activeX transformation tasks aren't possible in SSIS ?
I know ActiveX script tasks are but for transformations ?
1. IF i leave these Encapsulated DTS 2000 tasks in the migrated SSIS package, will it run independently of the original
DTS or does it need the old DTS running to "call" that part from ? (I hope im making sense here)
is it possible to load this functionality internally into the new SSIS ?
2.
How could I (if i can't do ActiveX transformation tasks) achieve this is SSIS ?
can I achive this using the script tasks in SSIS ?
Hi,
I'm facing a problem with my SSIS package regarding the execution order of tasks. I am using my package for the purpose of loading data from XML to staging tables in the database, and have a loop to process all XML files.
As a precondition to the loading action itself, I am running a stored procedure against the database (using the ExecuteSQL task) to check whether all staging tables are empty. The output parameter of that stored procedure is mapped to a variable I have defined in the SSIS package, so I can use it as a basis for the decision whether to run the loading action or not.
In order to test my package I added a script task, right after the execution of the stored procedure with a precedence constraint, that pops up a messagebox with the value of the stored procedure return value stored in the package variable.
The problem is that for the first iteration of the loop, the variable value presented by the messagebox is incorrect (equals to the initial value I assigned to the variable), and it looks like the script task starts before the stored procedure execution task finishes and its output value is stored in the package variable.
Please assist.
Hello all -
Working on DTS packages we used to have two different ways of exporting data to spreadsheet... We could do it by a single transformation task or either writing an ActiveX script, after running a procedure.
I am able to cover the first way already, while dealing with SSIS... But, I wonder if it is worth to research on how I would write a vb.net code to load data into a spreadsheet (considering we are advised to try vb.net instead of ActiveX while working on these new packages).
It is always a huge discussion to know what is the best way of doing something so my point here is to hear some of you and decide if I just keep exporting data by doing transformation tasks or if I will ever go trying to deploy a vb.net code to do that... What is the best on performance, etc...?
Thanks in advance for all your help as always.
Hello,
How would you do a log in a massive rows loading, I'm having problems because every row error(because of casting, format, lookup) in a transformation task is redirected to a text file as a log, this is ok when only exist one error by row, but in the case when I have two errors in the same row detected by diferents transformation tasks only the first one is reported to the text file, I have to wait to the second information load, after I correct the first error, to find the second one, I need to validate as many errors exists by row in the same load...
which component or which strategy can I use in a SSIS Packge to achieve this?
thanks
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???
Run the SSIS import/export wizard.
(xls -> sql table)
Select the tasks created.
Copy.
Here is the error that occurs.
p.s. Does anyone have any needles I can borrow? I think sticking them in my eyes would be nicer than working with SSIS.

Hello everybody,
I need some help :
I want to transfer a few access mdb kept in a folder to sql server. I am using foreach file enumerator. I want to perform the following actions :
1. At time of loading the file, check if the file name starts with "ED". If not, move the file to error folder.
2. Count no. of records that were there in the access db and that were transferred to the sql table.
3. I also want to run the package from command line. Even though i figured out that, i want to display only limited messages on the console. For eg: File processing begins, File currently being processed, TOtal rows transferred, File processing completed etc.
Please guide me with some examples.
thanks mint.

What are peoples opinions on using SSIS as a "central repository" and replacement for all scheduled tasks. Example, we have a bunch of servers which we have installed services which we have written. Currently we have scheduled tasks on each machine to stop and start the services. One of my collegues is using SSIS to run a system which runs tasks on multiple machines by remotely running programs on other machines via scheduled tasks and then collects the data and puts it into a database.
He's now pitching the idea that we remove the scheduled tasks on each machine and start and stop our services via SSIS so that it's centralized. In addition, we can also check for holidays in our database before starting services. Since it doesn't seem like SSIS was meant for this type of use, I'm weary of using the tool to do something it wasn't intended for.
Any opinions? I'm also worried that the learnnig curve for everyone is going to be too high.
I have this procedure to remove certain characters from file names.
The SQL Task has this: exec dbo.spCleanseFileName @strFileName = ?, @strFileNameCleansed = ?
The stored procedure:
CREATE PROCEDURE [dbo].[spCleanseFileName](@strFileName varchar(40),@strFileNameCleansed varchar(40) output)
I have it in an SSIS package and my problem is that, after that SQL Task completes, the value for the
),@strFileNameCleansed variable is blank. I HAVE confirmed that the procedure DOES set the correct value inside the SP.
Thanks in advance in reading this thread.
I have developed a big SSIS package to extract data from flat-files ( + 200 Dataflows ).
The situation is the following, inside de SSIS package, there are a lot of validations before extracting & loading the flat-files, i'm running this validations in paralell, so that when a file arrives, it enters the "validation process" and start extracting the file.
When i run the SSIS package from BIDS it works the way i have concepted it... but when i run the ssis in the server, the tables that are loaded through the process are only "available" when the SSIS PACKAGE ends, it is imperative that trough the process, when a table receives new data, it becomes ready, and don't just be available when the SSIS package finishes...
I have attached the an lousing .jpeg.
It is importart for the tables to be available, so the stored procedures(OUTSIDE SSIS PACKAGE) that are dependent of some tables, start working before the SSIS package Ends.
Thanks in Advance.
Hi
I have a strange problem with SSIS packages.
(brief description - packages select some data from DBs , write them to CSV file and then CSV file is
copied and renamed to a folder made up of the date)
I have 5 packages scheduled to run, these jobs run perfectly when test scheduled during the day,
(so its not a user permissions problem).
However it seems the 1st package to run at night will fail.
The reason I say 1st is the following,
I had Package A scheduled at 11:20PM and package B at 11:30PM , Package B always succeeded
but package A always failed.
I would test A during the day and it would run fine (the jobs would run successfully aswell as just executing the package manually) .
The I changed the time with B to 11:50PM and it succeeds and A fails ! without changing the packages themselves.
This counts out a possibilty of a DB backup causing the problem (pack always succeeded at 1130, now fails at the same
time)
I was thinking maybe as the folder wasn't created when the 1st pack ran this was causing the fail, but when i test run the job
this morning it succeeds .. and todays folder doesn't exist either !
any ideas ?

HI All,
I have Uzip Files to be downloaded From ftp.companyname.com, the zip files get updated everyday thus i have to download the newly added files, the Zip file has got 13 text Files within it, the issue is:
1. how do i download it for the new zip file only, the zip files are shown below, i am trying using FTP Task, but need more info or other alternative.
2. (Optional) How do i UnZip it and and take the text files and then load them to sql server 2005, each text file has to be loaded to sql server tables.
3. How do i automate it, i mean every time i run the package (on Job based) it has to look the new file only, see the zip file below to understand what i am saying about.
02/25/2008 09:02PM 2,780,729 CompanyName_2008-02-22.zip
02/27/2008 09:04PM 1,274,557 CompanyName_2008-02-23.zip

03/04/2008 04:49PM 3,238,121 CompanyName_2008-03-03.zip
As you can see the Zip file names are the blues color, they are added at different time, when you browse the ftp.companyname.com you will get the blue color files, thus what i need is to download only the current Zip file (i mean i have to downLoad only the newly added Zip file (recent one)). Thus the SSIS Task has to go to this FTP server and look the newly added zip file. (Optional) if possible, After that i have Unzip it b/se i have 13 text files there, and then Load them to Sql Server 2005.
Please get help on this, the deadline is near by time, if possible try as soon as possible, I would like to say Thank you for every help you do and try.
Thanks,
I'm trying to do some custom SSIS logging using event handlers, similar to the ideas provided by Jamie Thomson in the past. My problem is that when I use System:ourceID as one of the items to be logged, I can't match up the SourceID to any of the GUIDs that are displayed in the property window for the various tasks in my package.
Where is this sourceID coming from and how can I track it down?
Thanks for any insight on this.

I can't find information on how you are suppose to handle the TransactionOption setting inside of a custom task.
I have a custom task that I have developed, and it basically calls a COM+ object that writes data to a database. When I have the task inside of a container that has the transactionoption set to required, and my custom task is set to supported, if one of the X items fail to execute in my custom task I am telling my task to fail the parent, which I thought would rollback everything. But it does not.
Is there someplace that I need to write rollback code in custom SSIS tasks? If there is I can't find any mention of it anywhere. Any examples out there on how to build custom SSIS tasks that support the TransactionOption parameter?
Thanks!

I am finding difficult to set Expression Property "SelectedDatabases" in Check Databases Integrity Task in SSIS.
I keep getting error:
TITLE: Expression Builder

Expression cannot be evaluated.
ADDITIONAL INFORMATION:
The data type of variable "User::varDataset" is not supported in an expression.
Reading the variable "User::varDataset" failed with error code 0xC00470D0.

I need the flexibilty to be able to control the Task behaviour during runtime through Variables.
Any suggestions .... or even a different approach will be helpful..

Hello -- I primarily use SSIS for data loading tasks from falt files into SQL Server DB.
I usually have the Loading Fallouts routed to a FALLOUT Table with SSIS Err Codes.
However, the package execution stops if there are a bunch of fallouts.. like more than 20/30..
Is there any place in the package where i can specify a bigger Number, rather than Err'ng out for more than 20/30??
Thank You!

Hi,
I have a SQL 2000 script which I use to automatically schedule various backup tasks. This script adds and schedules a full backup once a week, differential backups nightly, and log backups hourly, in addition to a couple other maintenance tasks such as rebuilding indexes.
The idea is that a less technically savvy person can set a few variables at the top of the script (such as DB name and backup file folders) and click 'execute' to run the script and schedule the backups etc all in one go, for different clients.
Since some of the stored procs I use in this script are deprecated in SQL 2005, I am trying to replicate this functionality in SSIS but am having trouble figuring out how I can get all of this functionality encapsulated in the same 'click and go' manner where the user can simply execute the package and all the jobs will be scheduled without any user interaction.
Is this even possible? Where should I be looking for examples of how to do this?
Thanks!
Hey guys,
I created a script task in my package that checks for filenames of files that are to be processed by the package.
for example, File.txt contains a header row of "File.txt|03252006"
what my script should do is to check whether or not the actual filename matches the header record inside..
If File.txt has a header record of "readme.txt|03252006" then the script should raise an alert or notification but not fail the package..
I am lost here.. I have no idea how to access the SSIS package's events/alerts from within my script task..
my code looks something like this:
'Get Filename from File Connection String
Dim strFile_Name As String = strFile_Conn.Substring(strFile_Conn.LastIndexOf("") + 1, strFile_Conn.Length - (strFile_Conn.LastIndexOf("") + 1))
'Get Filename from header
Dim ReadHeader As StreamReader = New StreamReader(strHeader)
Dim HeaderFileName As String = ReadHeader.ReadLine()
ReadHeader.Close()
HeaderFileName = HeaderFileName.Substring(0, HeaderFileName.IndexOf("|"))
If strFile_Name <> HeaderFileName Then
<I don't know what to put here I should raise an alert or notification that the file identification failed.>
End If
Thanks in advance guys, I hope someone would be able to help me

I have begun using SSIS and I am a little taken aback by the complexity of it especially since I just want to do a simple data transformation such as in DTS.
Are there any tutorials for data transformation for SSIS on the web/this forum and what if I want to do a simple transformation from Access to SQL Server?
Hey all - got a problem that seems like it would be simple (and probably is : )
I'm importing a csv file into a SQL 2005 table and would like to add 2 columns that exist in the table but not in the csv file. I need these 2 columns to contain the current month and year (columns are named CM and CY respectively). How do I go about adding this data to each row during the transformation? A derived column task? Script task? None of these seem to be able to do this for me.
Here's a portion of the transformation script I was using to accomplish this when we were using SQL 2000 DTS jobs:
'**********************************************************************
' Visual Basic Transformation Script
'************************************************************************
' Copy each source column to the destination column
Function Main()
DTSDestination("CM") = Month(Now)
DTSDestination("CY") = Year(Now)
DTSDestination("Comments") = DTSSource("Col031")
DTSDestination("Manufacturer") = DTSSource("Col030")
DTSDestination("Model") = DTSSource("Col029")
DTSDestination("Last Check-in Date") = DTSSource("Col028")
Main = DTSTransformStat_OK
End Function
***********************************************************
Hopefully this question isnt answered somewhere else, but I did a quick search and came up with nothing. I've actually tried to utilize the script component and the "Row" object, but the only properties I'm given with that are the ones from the source data.
thanks in advance!

hi all,
My issue is the inner join transformation in SSIS.
See i ll explain my problem clearly now.....
Actually i m just checkin if the inner join performed in business intelligence studio usin the inner join transformation and the inner join performed in the management studio using queries are same. Logically both the resultset should match isn't but in my case it is not so. It is very important for me to figure out where the problem is because i m goin to use lotsa inner join transformations in my current project.
I ll appreciate if someone can help me to figure out this problem. May be you can also tell me the detailed steps in adding the inner join transformation and also how it works.
Thank you,
I have the following query:
SELECT EMPID,EMPNAME from EMPLOYEE
where EMPID = (SELECT MAX(EMPID) from EMPLOYEE group by EMPNAME,insert_date)
Here one can use above query in Dataflow of SSIS and specify SQL to create temporary table and later can use as lookup to join to other table.
Is there any way in SSIS to directly do the MAX of EMPID in lookup and join to the main source table.
Any help is really appreciated.
Thanks.
I want to delete all files in a given folder that are older than 3 days from today's date.
I tried using a "Foreach Loop container" with a "File System" task inside it but found I couldn't access any file properties such as the file creation date. Am I using the wrong task for this job?
TIA,
Barkingdog
P.S. History of the problem:
I used the sql 2005 Database maintenance program to setup our database backup jobs. One day I noticed that the free space on the drive where we keep the dumps had grown small. I found that we had at least 4 weeks of dumps in there, not the 3 days I wanted to keep! I looked but could not find the "delete file" option in the SSIS package generated by the Database Maintenance Wizard. No wonder the files were piling up.
Hi
I have a script component task that uses a column (which contains filenames) as input,
my problem is i cant access this in the script ? the column name is "Document"
and i've tried Me.ProcessInput("Document")
Ive been using SSIS for a month or two and now find I need to create some custom tasks to perform some performance logging. in the the overloaded ProviderComponentProperties section I am trying to create a property which has the same look as the Expressions properties you find elsewhere (Little + on the left and a group of sub properties when expanded).
Ive have played with creating a IDTSCustomPropertyCollection90 collection then adding my sub properties to it but I cant seem to then add my new collection to the ComponentMetaData.CustomPropertiesCollection.
Im assuming the Expressions parameter is a collection added to the properties collection but I cant figure out how. Any help would be much appreciated.
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 some "Execute T-SQL Statement Tasks" in a package. I would like to run this same package on another SQL Server without having to change it on the other server. Since the server name can be given when setting up the connection, I think if I leave the server name out then the package could run on any server? Is my assumption correct?

As a beginner I have created some Packages to import Data to SQL Server.
The Packages are running well.
I have created a Task to run the Package on a SQL SERVER 2005 Express. The Task starts.
Then a Execute Package Wizard Picture appears on the Screen.
I have mannually to select the Connection Manager and the Connection String.
After the selection the Task runs without any Problem.
Now I like to get the Task to run without any manual intervention.
I was looking in Internet but could not find a solution.
Can someone give me a hint how to get the Task working without intervention?
Thanks for an early answer.
