Type 1 Dimension Insert/Update
Jan 16, 2006
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

I have a Type I SCD situation, ie, insert if new (by checking the business ID) and update if any attributes for a given business ID has changed.
The way I usually do this, (and I believe this is how most people do it), is I use a LOOKUP TASK to determine if the business ID exsist in the target table. If it doesn't then I insert. If the business ID exists, then I bring back the associated attributes and use a CONDITIONAL SPLIT TASK to compare if any of the incoming attributes are different. If there are changes, then update.
In doing this comparision, I often run into situations where I end up comparing a NULL value to something, which does not result in FALSE, but a NULL result. To get around this, I first check for NULLs and convert them into something valid before I do the comparision, but this results in a messy comparison expression, especially if I have to compare a lot of attributes.
So, how do you guys handle this?
As an alternative, I am looking into the SLOWLY CHANGING DIMENSION TASK, which I also have some questions on, but I would like to first address the above. Thank you.

The warehouse I am writing packages for has sort of a "Type 1.5" design for most of its DIMs that I am trying to get to work with the slowly changing dimension object.
Basically it should behave like a type 1 with updates in place BUT send the old prior rows/values to an "archive" server to hold the historical data. Unlike a Type 2 this data will not be used for any processes - but it needs to be kept for historical reseach and auditing.
Any ideas to easily do with the SCD wizard? I thought using the wizard as a type 1 and then after the wizard is done attaching the "Historical Attribute Inserts Output" to the archive db/table would do the trick but that output from the SCD object never has data. I could manually do it with a lookup and so forth but I thought I'd check in here first to see if I am just overlooking something with the SCD object.

Hi all,
Maybe someone here can help me out: I have a Kimball type II dimension, where i track changes in a hierarchy. Each row has a RowStartDate and RowEndDate property to indicate from when to when a certain row should be used.
Now i want to load facts to that table. So each fact will have a certain date associated with it that i can use to lookup the right Id (a certain SourceId can have mulitiple integer Ids when there are historic changes) and then load the facts.
Is there a building block I can use for that? I could do this with SQL scripts but the client would prefer to have as much as possible done in SSIS. The Lookup transformation will only let me specify an equal (inner join where A=B) join, but i need equal for one column (SourceId) and then >= and <= (RowStart and RowEnd) to find the right row version.
Any ideas? Thanks in advance,
John

I am trying to use the Bulk Insert Task to load from a csv file. My final column is a bit that is nullable. My file is an ID column that is int, a date column that is mm/dd/yyy, then 20 columns that are real, and a final column that is bit. I've tried various combinations of codepage and datafiletype on my task component. When I have RAW with Char, I get the error included below. If I change to RAW/Native or codepage 1252, I don't have an issue with the bit; however, errors start generating on the ID and date columns.
I have tried various data type settings on my flat file connection, too. I have tried DT_BOOL and the integer datatypes. Nothing seems to work.
I hope someone can help me work through this.
Thanks in advance,

I Create a measure group and two dimensions using [AdventureWorksDW2012], I try to change one dimension's storage mode with setting property proactive caching as Real-Time ROlap. There is no any warning message when deploying and processing, but error occurs when I query in sql server analysis services, see below for the error messages and the screen capture.
Error occurred retrieving child nodes: the current operation was cancelled because another operation in the transaction failed.

I have dimension data like this
persn_key persn_id address is_active updated_date
1 10 NYC 0 2015-11-04 14:19:54.817
2 10 Chicago 1 null
and Fact table like
fact_key persn_key units_purchased
1 1 10
persn_key is the surrogate key between tables.
My question here is as the dimension has SCD type 2 on it and every time when there is a change the persn_key gets a new key value but the fact table still points to oldest key.how to update the surrogate key on fact table to the current key value? As per the requirement fact surrogate key must be pointing to current active record on the dimension.

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
My datasource from ORACLE and my datawarehouse in mssql2005

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?

Hi there!
I have some troubles getting done a lookup... data i get from a legacy system has to be cleaned up and split up into normalized form. i get invoice data and want to split up invoices into a separate table as customers. therefore i lookup if the customer of the current line is not already in my newly created customer-table. if it isn't there (error output of lookup transformation) i insert it into the customer-table.
The problem is that after the customer is inserted into the customer-table, it still is not found by the lookup transform because the lookup uses caching to hold the reference table (and so is the exact same customer inserted again and again and again). Is there any way to disable caching and let the lookup transformation do a select for every new row it gets? or at least refilling the cache if some event happens?
Many thanks in advance!

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

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!

If I have a table with 1 or more Nullable fields and I want to make sure that when an INSERT or UPDATE occurs and one or more of these fields are left to NULL either explicitly or implicitly is there I can set these to non-null values without interfering with the INSERT or UPDATE in as far as the other fields in the table?
EXAMPLE:
CREATE TABLE dbo.MYTABLE(
ID NUMERIC(18,0) IDENTITY(1,1) NOT NULL,
FirstName VARCHAR(50) NULL,
LastName VARCHAR(50) NULL,
[Code] ....
If an INSERT looks like any of the following what can I do to change the NULL being assigned to DateAdded to a real date, preferable the value of GetDate() at the time of the insert? I've heard of INSTEAD of Triggers but I'm not trying tto over rise the entire INSERT or update just the on (maybe 2) fields that are being left as null or explicitly set to null. The same would apply for any UPDATE where DateModified is not specified or explicitly set to NULL. I would want to change it so that DateModified is not null on any UPDATE.
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded)
VALUES('John','Smith',NULL)
INSERT INTO dbo.MYTABLE( FirstName, LastName)
VALUES('John','Smith')
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded)
SELECT FirstName, LastName, NULL
FROM MYOTHERTABLE

I have a web form with a text field that needs to take in as much as the user decides to type and insert it into an nvarchar(max) field in the database behind. I've tried using the new .write() method in my update statement, but it cuts off the text after a while. Is there a way to insert/update in SQL 2005 this without resorting to Bulk Insert? It bloats the transaction log and turning the logging off requires a call to sp_dboptions (or a straight-up ALTER DATABASE), which I'd like to avoid if I can.

I'm working on inserting data into a table in a database. The table has two separate triggers, one for insert and one for update (I don't like it this way, but that's how it's been for years). When there is a normal insert, done via a program, it looks like the triggers work fine. When I run an insert manually via a script, the first insert trigger will run, but the update trigger will fail. I narrowed down the issue to a root cause.
This root issue is due to both triggers using the same temporary table name. When the second trigger runs, there's an error stating that a few columns don't exist. I went to my test server and test db and changed the update trigger so that the temporary table is different than the insert trigger temporary table, the triggers work fine. The weird thing is that if the temporary table already exists, when the second trigger tries to create the temporary table, I would expect it to fail and say that it already exists.I'm probably just going to update the trigger tonight and change the temporary table name.

Hello
I've to write an trigger for the following action
When a entry is done in the table Adoscat79 having in the index field Statut_tiers the valeur 1 and a date in data_cloture for a customer xyz
all the entries in the same table where the no_tiers is the same as the one entered (many entriers) should have those both field updated
statut_tiers to 1
and date_cloture to the same date as entered
the same action has to be done when an update is done and the valeur is set to 1 for the statut_tiers and a date entered in the field date_clture
thank you for your help
I've never done a trigger before

Hello,I am writing a stored procedure that will take data from severaldifferent tables and will combine the data into a single table for ourdata warehouse. It is mostly pretty straightforward stuff, but there isone issue that I am not sure how to handle.The resulting table has a column that is an ugly concatenation fromseveral columns in the source. I didn't design this and I can't huntdown and kill the person who did, so that option is out. Here is asimplified version of what I'm trying to do:CREATE TABLE Source (grp_id INT NOT NULL,mbr_id DECIMAL(18, 0) NOT NULL,birth_date DATETIME NULL,gender_code CHAR(1) NOT NULL,ssn CHAR(9) NOT NULL )GOALTER TABLE SourceADD CONSTRAINT PK_SourcePRIMARY KEY CLUSTERED (grp_id, mbr_id)GOCREATE TABLE Destination (grp_id INT NOT NULL,mbr_id DECIMAL(18, 0) NOT NULL,birth_date DATETIME NULL,gender_code CHAR(1) NOT NULL,member_ssn CHAR(9) NOT NULL,subscriber_ssn CHAR(9) NOT NULL )GOALTER TABLE DestinationADD CONSTRAINT PK_DestinationPRIMARY KEY CLUSTERED (grp_id, mbr_id)GOThe member_ssn is the ssn for the row being imported. Each member alsohas a subscriber (think of it as a parent-child kind of relationship)where the first 9 characters of the mbr_id (as a zero-padded string)match and the last two are "00". For example, given the followingmbr_id values:1234567890012345678901123456789021111111110022222222200They would have the following subscribers:mbr_id subscriber mbr_id12345678900 1234567890012345678901 1234567890012345678902 1234567890011111111100 1111111110022222222200 22222222200So, for the subscriber_ssn I need to find the subscriber using theabove rule and fill in that ssn.I have a couple of ideas on how I might do this, but I'm wondering ifanyone has tackled a similar situation and how you solved it.The current system does an insert with an additional column for thesubscriber mbr_id then it updates the table using that column to joinback to the source. I could also join the source to itself in the firstplace to fill it in without the extra update, but I'm not sure if theextra complexity of the insert statement would offset any gains fromputting it all into one statement. I plan to test that on Monday.Thanks for any ideas that you might have.-Tom.

I have Repeater which has checkbox to delete selected items.
Dim strID As String = ""
Dim newStrID As String = ""Dim anItem As RepeaterItem
For Each anItem In Repeater1.ItemsDim chkBoxDelete As CheckBox = anItem.FindControl("Delete")
If chkBoxDelete.Checked Then
strID += (CType(anItem.FindControl("ID"), Label)).Text + ", "
End If
Next
If Len(strID) > 1 Then
newStrID = Left(strID, Len(strID) - 2)
Else
newStrID = ""
End If
It's working great, but if I implement it with Update statement, it doesn't work when it has more than one items (it's working fine with one item).
If I just print the statement, it's
UPDATE dbo.mytable SET active='N' WHERE id IN (1, 2, 3, 4)
Dim sqlStr As String
sqlStr = "UPDATE dbo.mytable SET active='N' WHERE id IN (" + newStrID + ")"
Dim cmdUpdate As New SqlCommand(sqlStr, conn)
I think it's because of data type, since id is Integer and newStrID is string. What should I do to make it work?
Thank you.

Hiya, last one (for a while), I swear. I'm getting the hang of this now (famous last words).
I've got a data file saved as an image type in my SQL Mobile database,
and I'm trying to send it over to my SS2005 Server via RDA, which seems
the simplest way possible. The application will only have
periodic rows to send over and insert into the Server's DB, so it seems
like doing a merge or a push is unnecessary overhead.
Is there some way to include parameters in the SQL string argument to
the method SubmitSQL? Or, embed the byte array into the SQL string? For
the life of me, I can't figure out how to do this.
So, if column data has type image, my statement would look like what?
string sSQL = "INSERT INTO sensor_stream (data) VALUES (what goes here?)";
rda.SubmitSql(SQL, strSQLConn);
.....
I've seen the solution being able to assign the image by using
parameters, but it seems that solution is not an option in this case?
Thank you in advance for your time and effort, I appreciate any and all help very much.

Topology:
Merge Replication (Using Web Sync anonymous pull subscriptions)
SQL 2005 SP1 all nodes
Scenarios:
I have two subscribers both have sync'd and data appears fine. Then one of the subscribers deletes a row whilst the other subscriber makes an update to the same row. The subscriber who deleted sync's first and the row has gone from the subscriber DB and the Publisher DB.
The second subscriber who still has the newly updated row in it's DB then sync's. There is a conflict of Type 3 (Update Delete Wins Conflict) which the conflict resolver states that the last subscriber to sync lost the conflict and the deleted row wins.
However this has caused problems. After sync has occurred the second subscriber still has the updated row in it's DB. The row does not exist on either the publisher or the subscriber where it was deleted. The data has become non-convergent.
I have used the Microsoft COM resolver Last Datetime wins and specified our [lud] datetime column. Now in my understanding in a type 3 situation the winning row (The deleted row) should be propogated to the publisher and subscriber and thus the data should have been removed at all nodes regardless of whether it had been updated or not.
Also to add another twist, the delete was performed before the update (Chronologically speaking) therefore I would assume the resolver should have taken the update to be the winning row (i.e. Type 4 Update Wins Delete Conflict) at least because a deleted row will have NULL in the [lud] column therefore the updated row with a NON NULL value for [lud] would be the winner.
Am I missing something here, or is the resolver not performing as described in Books On-Line
Cheers
