How To Update A Dimension Column With The Pipeline Tasks
Oct 19, 2006
I have been working with DTS and ETL in data warehousing projects for several years and my question is this. You can only update a dimension column with SSIS by using TSQL-update statements.
There is no way to do this except issuing TSQL from the control flow or the data flow?
This subject is not mentioned in Wrox SSIS book nore in Kirk Haseldens book.
When you run the SCD task in the data flow you will get an OLEDB command that actually do this, issue a TSQL-statement.
Is this correct?

I'm building a custom transform component. I want to mark some input columns as keys for deduplicating. In a similar way to the provided Sort component, I want to check those columns and allow pass-throughs (or not) for the others - so next to each input column name I need two checkboxes (1:use for dedupe; 2:include in output if 1 not checked). If a column is checked for use in the dedupe, I want some other attributes to be shown indicating how it will be used. How do I display the checkboxes to let users select which columns to include for deduplication, and then how do I add further attributes underneath (copying the Sort component's look) for selection?
Thanks in advance for guidance and pointers on this.

Hi,
I need to access columns from a data flow by ordinal position in a script transformation (I'm parsing an excel file which has several rowsets across the page). The first problem I encountered is the generated BufferWrapper does not expose the columns collection (i.e. Input0Buffer(0) does not work) but I got around that by implementing my own ProcessInputs(InputId, Buffer) method instead of using the wrapper.
My problem now is that the column ordinals are in some random order (i.e. Column "F1" is ordinal 1 but Column "F2" is 243). Where in the object model can I map between the name and the ordinal - it's not jumping out at me?
Dave
PS Why is the script editor modal, it's frustrating having to switch between the Visual Studio environment and the VSA one.

The scenario is as follows: I have a source with many rows. Each row has a column called max_qty_value. I need to perform a calculation using another column called qty. This calculation is something similar to dividing qty/(ceiling) max_qty_value. Once I have that number I need to write an additional duplicate row for each value from the prior calculation performed. For example, 15/4 = 4. I need to write 4 rows to the same target table as in line information for a purchase order.
The multicast transform appears to only support fixed and/or predetermined outputs. How do I design this logic in SSIS to write out dynamic number of rows to a target table.
Any ideas would be greatly appreciated.
thanks
John

Dear all,
Now I create datawarehouse for my client, I have SSIS a lot for ETL process, I a problem that some fact table need to be updatetable and there is a lot of data of this, I need some efficent way to load this data to data warehouse.
I have read your article about SCD in SSIS (Slowly Changing Dimensions in SQL Server 2005).
I think the purpose of SCD for Dimension table. If I have some fact table that need rows to be updatetable can you give me an example, best practice, the efficient way or fastet way to load fact table that can be updatetable?
If you have link or link about this problem please reply my email. Thanks

Hi
I'm trying to put together a integration package that loads in type 1 dimensional data. If the item is new then the data is inserted if it already exists then it is overwritten. My approach has been to use the lookup operator to match the source values against a generic mappings table. The data that is matched goes off into the error flow and is inserted as new rows in the dimension table. The matched lookup rows are sent through into an update operator. the problem comes when there are no new rows for the lookup operator to find it still want to do the inserts and so exits with an error code.
I tried to change the data flow so that it uses and outer join and conditional split to decide what rows are matched and what are new, however when there are no new rows it reaches the inserts and exits with an error again.
Is containing the logic for insert and update in the one data flow a poor approach? should the conditional processing logic be placed in the control flow?
For the Oracle people out there all I'm trying to do is a MERGE!!! there must be an easier way
Cheers
Al

Hi All,
I would like to know whether it is possible to add and updated date column in a slow changing dimension table using the slow changing dimension data flow transformation.
I would like to keep track of what record is updated in the dimension table based on the data being processed.
Thanks for you help and information

Hi
I am working as datawarehous architect with a large concern and i designed a datamart witha fact table surrounded by 5 dimension tables. My PM who do not know datwarehousing has abruptly changed my design and instead of 5 dimension tables has increased to 17 tables which just 1 column each in them.
This is hell of a design because if it is a single column dimension then there can not be any hierarchy in the dimension table , better will be to push this column as a fact.
What should I do now. Moreover he has asked me to not to use SSIS and code everything in stored procedure.
Please guide.

In the SSIS Analysis Services processing task, I was wondering if
anyone knows why some dimensions do not have the Process Update option
in the list of options for processing them? If there is
only Process Full, Process Data, and Unprocess, I am not sure how
I can do incremental updates without scripting.
Also, will this affect the cubes if a full process is performed?
Any help is much appreciated!

I have added a Slowly Changing Dimension transformation to an SSIS package and have launched the Wizard to edit it. After selecting the source (a SQL Server 2005 instance), if I select a very large table (9+ million rows), I'm encountering two strange behaviors:
1. The wizard hangs for several minutes before displaying the columns from that table.
2. The wizard does not display the primary key column. This, of course, is the column I want to designate as the "business key", but can't because it's not displayed.
I know this is more like a fact table than a dimension, but this is not a data warehouse. This is just a very large table, and I need to update a field in certain records based on the contents of a source text file. Is there another transformation I should use to perform updates?

Hi,
I want to incorporate this code but I dont know how to import Microsoft.SqlServer.Dts.Pipeline in an Integration Services Project template. I was thinking of putting this code in the script task but still, I cant import Pipeline. Add reference list does not have it as well. Please let me know how to incorporate this code. Thanks!
Code:
if (ComponentMetaData.RuntimeConnectionCollection["SourceFileConnection"].ConnectionManager != null)
{
cm = DtsConvert.ToConnectionManager(ComponentMetaData.RuntimeConnectionCollection["SourceFileConnection"].ConnectionManager);
if (cm.CreationName == "FILE")
{
fileUsage = (Microsoft.SqlServer.Dts.Runtime.DTSFileConnectionUsageType)cm.Properties["FileUsageType"].GetValue(cm);
if (fileUsage == Microsoft.SqlServer.Dts.Runtime.DTSFileConnectionUsageType.FileExists)
{
connectionString = ComponentMetaData.RuntimeConnectionCollection["SourceFileConnection"].ConnectionManager.AcquireConnection(transaction).ToString();
if (connectionString == null || connectionString.Length == 0)
{
throw new Exception("No file name specfiy");
}
}
else throw new Exception("Incorrect file connection usage type, should be set to exiting file type");
}
else throw new Exception("Connection is not a file connection");
}
else throw new Exception("Connection is not as assign");

This is probably obvious, but how do I split a pipeline. I.e. I've got a data source with 200 columns - I need to split this into 20 pipelines each containing 10 of the original columns.

Bitmask fields! I am capturing row changes manually via a high frequency ETL task. It works effectively however i am capturing the movement of multiple fields. A simple example, for Order lines, i have a price, a discount and a date. I am capturing a 001, 010, 100 respectively for each change.
I would like my users to be able to select from a dimension which has the 3 members in it and they can select one, multiples, or all values (i.e. only want to see rows that have had the date and price changed).
Obviously if i only had 3 columns i would use bit's and be done with it, i have many different values (currently around 24 and growing).

We have deployed an SSIS package successfully to production. We needed to apply SP1 to fix a different issue and now have encountered a new problem. We have numerous Data Reader Sources in different Data Flow Tasks that connect to a IBM iSeries (DB2) source. Pretty simple extracts that have worked fine in the past. They pump the data into staging tables on the SQL2K5 instance running the package (64-bit).
After we applied SP1 however, all of the Data Reader tasks fail AFTER they successfully copy the records with the following error.
[iSeries Invoice Details [1]] Error: System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.SqlServer.Dts.Pipeline.DataReaderSourceAdapter.PrimeOutput(Int32 outputs, Int32[] outputIDs, PipelineBuffer[] buffers) at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostPrimeOutput(IDTSManagedComponentWrapper90 wrapper, Int32 outputs, Int32[] outputIDs, IDTSBuffer90[] buffers, IntPtr ppBufferWirePacket)
If I delete the source and destination and recreate identical transforms, they work fine, but I don't feel like rebuilding all of the extracts. Any ideas! The problem occurs in all environments that we've tried.
TIA,
Michael Shugarman
P.S. I just tried the SP2 CTP, but that doesn't fix the problem.

Hi I have created a simple SSIS project on my client that carries out 4 Data Flow tasks, each one copying a few hundred rows from an Oracle 10.0.2 database. This works OK and will also run in debug mode fine.
I have copied the package to the file system on our development server and get the following error when in debug mode:-
[DTS.Pipeline] Information: Validation phase is beginning.

If you go to the source of each flow task and select preview you can retreive the data.

I have a situation where we get XML files sent daily that need uploading into SQL Server tables, but the source system producing these files sometimes generates duplicate records in the file. The tricky part is, that the record isn't entirely duplicated. What I mean, is that if I look for duplicates by grouping the key columns, having count(*) > 1, I find which ones are duplicates, but when I inspect the data on these duplicates, the other details in the remaining columns may differ. So our rule is: pick the first record, toss the rest of the duplicates.
Because we don't sort on any columns during the import, the first record kept of the duplicates is arbitrary. Again, we can't tell at this point which of the duplicated records is more correct. Someday down the road, we will do this research.
Now, I need to know the most efficient way to accomplish this in SSIS. If it makes it easier, I could just discard all the duplicates, since the number of them is so small.
If the source were a relational table, I could use a SQL statement to filter the records to remove the duplicates, but since the source is an XML file, I don't know how to filter these out in the pipeline, since the file has to be aggregated to search for dups.
Thanks

Hi
I have an existing application that programmatically builds SSIS 2005 packages.
I'm trying to get to working with the February CTP of SQL Server 2008. Having changed all the 2005 references to 2008 references and things like IDTSComponentMetaData90 to IDTSComponentMetaData100, my application compiles okay now, but hits a problem when it tries to create a Data Flow task.
The code which worked fine before (and seems to still be the recommended way in Books Online is):
Code Snippet
Dts.TaskHost myMainPipe = (Dts.TaskHost)container.Add("DTS.Pipeline.1");
However, this now produces the exception:
Cannot create a task with the name "DTS.Pipeline.1". Verify that the name is correct.
Should I be using a different moniker now? I took a stab at "DTS.Pipeline.2", but that didn't make a difference.
Thanks,
Andrew

Hello,
I'm wish to receive pipeline events fired by a SSIS package.
I execute the package successufully with the following code (c#):
MyEventListener eventListener = new XplorerEventListener();
DtsApplication app = new DtsApplication();
Package pkg = app.LoadPackage("c: est.dstx", null);
pkg.Execute(null, null, eventListener, null, null);
MyEventListener is inherited from DefaultEvents, overriding all OnXXX methods.
It works perfectly, however I cannot intercept the following events:
- PipelineExecutionTrees
- PipelineExecutionPlan
- PipelineExecutionInitialization
- BufferSizeTuning
- PipelineInitialization
Anyone knows how to catch those pipeline events?
TIA,
Paolo.

Alot of people complain, legitamately, that they wish to remove columns from the SSIS pipeline that they know are not going to be used again. This would help to avoid the "clutter" that can exist when there are alot of columns in the pipeline.
If you are one of those people then click-through below, vote and (most importantly) add a comment. The more people that do that - the more likely we are to get this functionality in a future version.

I have several stage to star (i.e. moving data from a staging table through the key lookups into a fact table) ETL transformations in a single SSIS package. Each fact table has a different set of measures but the identical foreign key set, e.g. ConsultantKey, SubsidiaryKey, ContestKey, ContestParamKey and MonthKey.
Currently I have to replicate the key lookup (Surrogate Key Pipeline, or SKP) for each data flow. If I could cache each dimension one time in the package and reuse it for each stage to fact it would be much more efficient.
Is there a way for me to reuse a common data flow?

I cannot get a simple package to execute a data pump to an access database from SQL2005.
I have tried it in both SSIS and by running the Export data function.
I have been able to write to this database in the past using dtp in SQL2000 but I am not able to write to it using SQL2005.
What is the deal with the new SSIS?
Does anybody have any ideas I can try to get my export to work.
I have many more to do and I have to migrate over all of my SQL 2000 DTS packages to SQL2005 and some export to MSAccess.
This is the only error message I can find:
[DTS.Pipeline] Information: "component "OLE DB Destination 1" (2196)" wrote 0 rows.
Edit:
I found more errors in the debug section and a post here that discussed the problem as they had run into it. I was able to use part of that and some more research in order to tackle my problem.
I would still be interested in finding out why I suddenly had this problem arise after I upgraded to SQL2005.
This is going to be a real pain as apparently SQL2005 treats NULL as Zero Length and now all of my databsaes that had that set in access will have to be modified to deal with this in the export.

I have a student table like this studentid, schoolID, previousschoolid, gradelevel.
I would like to load this table every day from student system.
During the year, the student could change schoolid, whenever there is a change, I would put current records schoolid to the previous schoolid column, and set the schoolid as the newschoolid from student system.
My question in my merge statement something like below
Merge into student st
using (select * from InputStudent ins)
on st.id=ins.studentid
When matched then update
set st.schoolid=ins.schoolid
, st.previouschoolid= case when (st.schoolid<>ins.schoolid) then st.schoolid
else st.previouschoolid
end
, st.grade_level=ins.grade_level
;
My question is since schoolid is et at the first line of set statement, will the second line still catch what is the previous schoolid?
