Which SSIS Dataflow Transformations Will Accomplish This Select Statement?
Apr 20, 2007
I'm trying to find if there is a combination of dataflow transformations that will produce the following result
SELECT
period,
project,
task,
employee = CASE
when empid in (SELECT DISTINCT empid FROM EmpTable) then empid
else 'Deleted Employee'
end
FROM ProjectTable
I know I can create a dataflow task with this query as a data source and then send it to a destination, but I was wondering if that is the best way to do it or if there was a better way to do this using the data transformations available in SSIS.
Any insight would be most appreciated.

Bill Webster

Hi all,
In my DataFlow i set the "OLEDB Source" which is a table in my Extract Server and need to do some transformations and stage the table which will be a Dimension in the staging DB,
Q1-Now i need only 3 columns from the Source table, which transformation do i need to use to just extract the the 3 columns?
Q2- Two Columns of 3,which i will need to transform as it is-no changes at all and One of the column which has values like "BOSTON...."
(I have a vague idea of what i need to do,need something solid suggestions/advices to kickoff,plan is to use this city column with a Replace function (as one of the forum member's Spirit1 adviced..thanks..!!))to take out the dots and then need to write a condition if BOSTON then Assign Code "BOS" which will be City_Code and this "City_Code" will have to be looked in City_Dimension to get the "City_Key_Number" for "Boston" and lastly the City_Code and City Key Number both have to be transformed to the destination Dimension.
Any ideas /suggestions will be appreciated.
Thanks in advance...!!

I€™m trying to populate a table with fields of date type [DT_DATE] using the Slow Changing Dimension Transformation component. When I add the date fields to the component it would not build the stream. The wizard fails and tells me the date fields are not of the same type. The fields in the destination table are of type €œdate€? and the input columns are of type [DT_DATE]. Am I missing something?

In good old fashioned DTS there was the ability to perform custom transformations using activeX / vbscripty type language - does this still exist or are we stuck with the derived column editor?

Hi,
I saw some thing called custom properties for the "Derived transformation" in the msdn site. I tried to use them in a simple package, but I am getting an error as "can't write to derivedoutputcolumnname.friendlyexpression". Friendly expression is one of the custom properties available for the derived transformation output columns.
The steps I followed to get to this error are as follows:
1) Get data from a table using OLEDB Source. Suppose I am getting firstName, LastName etc.
2) Derived column input is values from the above OLEDB Source.
3) I have added a new column called "Concatenated name" which is concatenated value of first and last names.
4) Then in the properties editor of this data flow task in expressions option I clicked on ellipse available. I got an editor for property expression, which contained two columns called "Property" and "Expression". Property column contains dropdown with friendly expressions propety for the derived columns and expression column is a text box, where in we can enter expression to be evaluated for the corresponding friendly expression property.
5) Now when I click on OK and try to debug it gives an error as "Can't write to concatenatedname.friendlyexpresiion".
If anybody has already faced this problem and solved it please let me know, because I am struck here a long time.
Thanks&Regards,

Greetings SSIS friends,
I have been attempting to implement one of our numerous ETL processes in SSIS but hit a brick wall when I tried replacing a complex stored procedure with a series of Merge Join components.
In the end, I had to settle with using a SQL task which merely calls the stored procedure and this proved to be the better option as the other version where I used SSIS components only took forever to run.
How do people cope with complex transformations?! Do you guys opt for pure TSQL to perform complex transformations and use SSIS components for control flow+simple(ish) data flow tasks?
I am confused.

I've read that SSIS tries to do all transformations in memory as a way of enhancing processing speed. What happens though if the amount of data processed exceeds the available RAM? Are raw files then used (similar to staging tables) or is an error generated?

Hi
I am new to SSIS and have the following problem. I used the following script to clear data in columns of any CR/LF/Commas and char(0)'s. Can I just transfer this to SSIS and how exactly do I do that? Any help or advice would help.
Function Main()
Dim x
For x=1 to DTSSource.count
If Isnull(DTSSource(x)) = False Then
DTSDestination(x) = replace(replace(replace(Replace(DTSSource(x) , chr(13),""),chr(10),""),chr(0),""),","," ")
Else
DTSDestination(x) = DTSSource(x)
End If
Next
Main = DTSTransformStat_OK
End Function

Is it possible to add a variable in SSIS like
name of variable: myVar
Scope: Data Flow Task
Data Type: String
Value:SELECT hello FROM blah WHERE (azerty = @[User::pda]) AND (qwerty = @[User::phone])
@[User::pda] and @[User::phone] are also variables in SSIS just like the myVar I made
I know I'm doing something wrong with the data type because it's stores the whole select statement as a string

I am using a OLE DB source task and i want to setup a parameter in the select statement. Is this possible and how would this be done. I know you can pass a parameter in the where clause like:
select id, lname, fname, startDate, endDate from Employee where id = ?
How would i set startDate and endDate as parameters as i would like to be able to change these parameters when running the package. I would like to set dates in the select statement as parameters like how you would in the where clause.
Select id, lname, fname, ? startDate, ? endDate, from employee where id = ?
I would like to be able to change these dates without having to go in to the package and hard code it back in there and then deploy.
The package uses a OLE DB source to Flatfile Destination.

Hi guys,
I need to use a SQL statement to lookup a value from a SQL server database table that relates to a column in my dataflow.
Imagine a SQL database table called 'cars' with values of
Year | Description
2005 Ferrari 355
2005 Ferrari 355 Spider
2006 Ferrari 355 F1
In my data flow I have Year and Model eg.
Year | Model
2005 355
2006 355
In my SQL statement I want to select from the 'cars' table where the years match exactly but the 'description' is like the 'Model'. eg. %355%
So essentially, how do I construct the 'like' clause in the select statement to reference the 'Model' column please?
thanks for your help,
Chris

Hello
Trying to figure out a clever solution for splitting multivalued columns out into n-columns.
For that I've build a custom component in SSIS using
ms-help://MS.VSCC.v80/MS.VSIPCC.v80/MS.SQLSVR.v9.en/dtsref9/html/4dc0f631-8fd6-4007-b573-ca67f58ca068.htm as an example.
I need to be able to add columns to the OutputCollection in designtime, but the designer returns an error:
Error at Data Flow Task [Uppercase [5910]]: The component "Uppercase" (5910)
does not allow setting output column datatype properties.
How do I enable the designer to accept designtime changes in the
columncollection?
Kind regards

I created a dataflow that transferred about 1 million records from a SQL database on one server to a differend SQL database on the same server. The processing took about 30 minutes. I used the Fast Load option.
I then created a "Execute SQL Task" and wrote a "SELECT * INTO TABLE" and this processing took about 30 - 60 seconds.
Can someone tell me why creating a Data Flow Tak would take so much longer or give differences between the two options above? Can someone give some pointers on how to make a Data Flow task more efficient?
Thanks.

I am trying to recode a SQL2K DDQ into an SSIS Dataflow. I have no issue recoding it in SSIS except I am not sure that I am doing it correct way.
My DDQ has source,destination, update/delete/insert statements and few lookups. I have used activex script for the transformation because I have atleasst 10 If conditions. For every "if condition" the destination columns are popuated with different lookups/source columns and constant values.
Now When I start doing it with SSIS I have to use at least 10 Conditional split. and then at least one lookup,one OLEDBCommand and one OLEDB Destination for each of them . that brings my count of DF objects to 30-40
It makes my data flow to complex with two many objects. Earleir I could do whole of this in one sngle DDQ. It makes me think if I am doing it the correct way. should I be using Activex Script Task to these kind of activity.
Any advice would be appreciated.
Cheers,

Need help regarding ssis dataflow task
I need to create a ssis package. I want to import the data from a flat file to a table.
Lets say, the table has 5 columns -- col1, col2, col3, col4 , col5.(Assume that all columns can be NULLABLE) The datafile contains the data related to only three columns say col1, col2, col3. So when I use dataflow task to import the data from the file to the table, I will only get three columns, col1, col2, col3. Columns col4, col5 will be NULL.
However, I want to populate columns col4, col5 with some values which are stored in the variable.
IS there any way to do this??
Any help would be appreciated.

When I drop a new component onto the design surface, it appears with dotted lines around it, as it is selected.
But, the F2 key (the hotkey for rename) does not work.
I have to click on some other component, and then back on the new component, and then the F2 key works.
I remember reporting this bug back in the beta cycle, but it is still present even in the release -- I actually think Ã?'m using the SP1 version of 2005, but see version info below to be sure:
Remote terminal services broke my copy buffer again, as is so often does, so pasting in the version info failed -- falling back to manual typing -- SSIS 9.00.2047.00.

It just occurs to me that it might not be a bad idea to post again the problems in SSIS that I found back in the beta cycle which do not seem to have been fixed, to increase the chance that someone will notice them.
(During the beta cycle, I spent hours trying to get bugs posted into the beta bug system, but the beta web bug site had so many problems that I could never get it to work, unfortunately, so I fell back to just posting my bugs and hoping some developers would notice them. Kirk had a thread for bugs and RFEs at one point, where I posted some of the important ones.)
Here is another fairly bad one:
The dialog that pops up to show fields in the dataflow which have been orphaned, after some fields have been removed earlier in the dataflow, and which allows the user to rename them or delete them, has a very bad display problem:
It shows the box names before the field names, so if the box names are descriptive, the field names are far off-screeen, and it is very difficult to get them to display on screen.
So the user starts off with all the items in the drop-down being indistinguishable, as they all start with the box names, and the important part of the strings are far off-screen at the right -- the actual field names.
I don't recall if I actually ever posted this one; I may not have.

Okay I 'm not sure what to do next
(S2K5 64 bit SP2)
Migrated across simple DTS which picks data up from MSaccess and ships it into a database table!
I switched the 64bit run time to false and happy days it shipped the information across.
I then decided I wanted to deploy the package so I created a deployconfig.xml with all properties ticked against my two connections in connection manager. ( the MSacessdb and the S2k5 database )
after that I switched the deployment util to true.
then I fired the deployment manifest
Then created a job to schedule it fails with

created another job but ran TSQL
xp_cmdshell 'dtexec /FILE "D:DTSTrackit.dtsx" /MAXCONCURRENT " -1 " /CHECKPOINTING OFF /REPORTING EW'
I ran the job and it says succesful but when I do a query on the table there is no data could anyone please point me in the right direction? Thanks

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.

My apologies if this is a very basic question, but I am having a very difficult time finding the answer.
My very, very simple dataflow task is PAINSTAKINGLY slow. (It took over an hour to transwer @300,000 records). I'm doing no transformations whatsoever. In fact, the only reason I'm using the Data Flow component here is for its error tracking capabilities.
Here's a brief description-
1) The source is an OleDB datasource object that uses an OLEDB connection to access a SQL Server 2000 database.
2) The output from the source is dumped directly (no data transformations) into an OLEDB Destination Object (uses an OLEDB connection to access a View on a SQL Server 2005 database). Individual row errors are pushed to a seperate logging table.
Based on the advice of an article I read, I removed the "OleDB Destination" object and used the records from the OLEDB source as the input to a RowCount Transformation. This still took a SIGNIFICANT amount of time. I'm guessing that my problem is with using an OleDB Source component???? That seems really strange though... wouldn't it be optimized? What are my workaround options?
Any help is _much_ appreciated.
Thanks,
Jess

Hello, to give you a background on where I'm coming from:
I have an SSIS Package with a global String variable that has an sql statement. so it says something like: "Select * from MyTable "
I than have a SQL Script Task where I append a WHERE Statement to my string.
Than in the Dataflow Task when I select the source database, I run command from Variable.
When I run the package I get an error that my string is too long. My string is about 750 characters that I'm trying to pass through.
Is there some limitation to this?
I have ran the raw SQL Command in the SQL manager and it runs fine. I have built a million of these packages, just not one with such a large string.
If it is the case that it is just too long, is there a work around to that?
Thanks,
Rusty.

I have a problem whit loading XML-files into SQL server.
I iterate over the XML-files with the "for each file" component and use the XML source within a Data flow task. This works great until the file count got bigger. After say 1000 files the XML source returns error 0x8007000E. I think this means out of memory. Does anyone have an idea how to solv this. The load must be able to handle up to 5000 files in one batch.

Dear Friends,
I need to execute a SQL query, inside a dataflow (not in controlFlow) and need the records returned to continue the dataflow... In my case I cant use lookup and OLE DB COmmand and nothing else...
I need to execute a query and need the records for dataflow... with OLE DB command I cant see the fields returned... :-(
How can I do it? Using a script? Can I use a Script Component? That receive 2 parameters for input and give me the fields returned from query as output?

Hi Folks,
When I try to drag and drop the Multicast dataflow item onto the Data Flow design surface I get the error below. I have uninstalled and reinstalled SQL Server 2005 to no avail. By experimentation I have discovered that the following Data Flow Transformations raise this error as well:
DTSTransform.Aggregate.1
DTSTransform.Multicast.1
DTSTransform.Sort.1
Any thoughts, comments, or pointers? I would really like this to work!

New to SSIS and dts. Stumbling along on this one, really looking for resources and help.
I have a flat file, i defined through connection manager
and (for now) a fixed destination excel file I defined in connection manager.
My dataflow, is pretty simple, mapping two fields to each other an amount field and a phone field in a flat file source and excel destinatinon.
the amount column is formated as a number in the excel, and a currency in the connection and both input output properies.
A few questions,
1. why do cells on the excel show up with that green wedge on the upper left? appears to be a formating issue.
2. in the flat file, my amount field does not have the decimal, what would be the best way to apply that? it's should be implied.
3.Everytime I test the SSIS package, it keeps appending to the excel (it actually does not even work right on the second run). What's the best way to have it write to a fresh file? have an ssis script task copy the file from an empty template?
4. Id like to remove the last row? what's the best way to do that?
Thanks for any help or information!

OLE DB Destination ( database table )
upon execute of the SSIS
task one is fine
task two fails

Hi All,
I am using a Data Flow task which copies data from an Excel Source to a SQL Database Table Destination. From 15 columns I require only 10 columns to be imported to the DB Table. So I have mapped those colums. In SQL DB there is a colum called say X, whose value should be the "Remedy" for all the columns which are imported. Is there any task that can achieve it.
