I have a transaction table having about 40 crore rows in source. It don't have timestamp and unique key columns. It have only Bill_month and Bill_Year columns. Actually for loading this table into staging I have added a new datetime column by adding default bill_date as 01. Then
* First we delete last 3 month data from staging tables.
* Get last 3 months data from source table.
* Load that 3 months data from source to staging table.
We do this because we only get update for last three months data. Now I have to include this transaction table as Fact table in DW. What will be the best practice for loading the fact table by picking data form staging table. Also we have to look up with dimensions for Foreign Keys.
* Should I implement the same method of deleting last 3 months records and loading them again.
Greetings,
Iam new to SQLl2005. Iam using DTS to transfer data from my source to the warehouse. I have a couple of tables in my source whein I have to join these to tables fields and insert the same in teh warehouse fact table. I have used a Join query in my Oledb source component, What other component needs to be used to insert the data into the fact table.
I also need to extract same data with aggregation and insert the same into an another Fact table.
Kindly help.
Say you have a fact table with a few columns that all reference the same key column in a dimension table, you want to write a view to return the information for those keys?
USE MyTestDB;
GO
SET NOCOUNT ON;
IF OBJECT_ID ('dbo.FactTemp' ,'U') IS NOT NULL
DROP TABLE dbo.FactTemp;
[Code] ....
I'm using very small data at the moment, and the query plan and statistics don't really say which way.
I have to update a table in my sql database with data exported (csv, txt or xls) from another source. The source data and my table have a matching unique field. The source data may contain records I already have and need to updated with any changed data in the source file or new records that need to be inserted into my sql table.
I am using SQLExpress, SSMSE, ASP.NET 2.0, and VWD Express. I am relatively new to this environment. Can anyone suggest a solution or where I can find a solution?
I could do this when I was building apps in Access.
Thanks
George

I have 3 tables and 1 view. Which are:
TOWNLAND_GEOREFERENCE_POLYGON
PlanningPointLocation
paflarea
VIEW_paapplic
The View paaplic has 100 records and I have to do the below for all 1000 records individually.
I have to update the field TP_Total in the TOWNLAND_GEOREFERENCE_POLYGON table depending on what is in the fields in the tables.
I am writing the below code but am unsure if this is going to achieve what I want.
BEGIN
Select file_number, land_use_code, pluse1_code
From VIEW_paapplic
END
BEGIN
If pluse1_code = 'A' Then
Select TP_Total From TOWNLAND_GEOREFERENCE_POLYGON
WHERE PlanningPointLocations.Townland = TOWNLAND_GEOREFERENCE_POLYGON.Townland
AND PlanningPointLocations.File_Number = File_Number
Update TOWNLAND_GEOREFERENCE_POLYGON SET TP_Total As TP_Total + 1
WHERE PlanningPointLocations.Townland = TOWNLAND_GEOREFERENCE_POLYGON.Townland
AND PlanningPointLocations.File_Number = File_Number
Else If pluse1_code = 'C' Then
Select Count(*) As TempCount From table paflarea
Where fk_paapplicfile_nu = file_number
Select TP_Total From TOWNLAND_GEOREFERENCE_POLYGON
WHERE PlanningPointLocations.Townland = TOWNLAND_GEOREFERENCE_POLYGON.Townland
AND PlanningPointLocations.File_Number = File_Number
Update TOWNLAND_GEOREFERENCE_POLYGON SET TP_Total As TP_Total + TempCount
WHERE PlanningPointLocations.Townland = TOWNLAND_GEOREFERENCE_POLYGON.Townland
AND PlanningPointLocations.File_Number = File_Number
END
Anyone any ideas?

ok, i am trying to update a database at work for a product we are developing.
i need to run this command
update <tablenamehere> set value = Replace(value, 'GeoLynxAO_Henrico', 'GeoLynx')
on every tabe in the database
is there a simple way to do this while pulling the table names out of information_schema.tables?
i have searched using google and been unable to find anything so far. the db server is running sql server express 2005 and i'm doing this from sql server management studio express
i really don't want to have to type the update statement by hand for 90+ tables................
I have a dimension with a date field (int key value actually) that is generally null that I'm using to link to a time dimension. Everything works great when I set Null Processing to UnknownMember in the Measure Group Bindings, but if I try to set it to Preserve or anything else, I get processing errors because it can't match the null attribute key to the time dimension. I think I understand this, but I'm concerned that I'm not doing it the best way. Also, why does this page say "UnknownMember causes a data integrity error at processing time" when that's the only setting that does not give me errors?

I cannot create a measure that returns results for dates that do not exist in the fact table despite the fact that the components included in the measure contain valid results for these same dates.Creature a measure that counts the number of days where the "stock qty" is below the "avg monthly sales qty for the last 12 months" (rolling measure).Here is the DAX code I have tried for the measure (note that filter explicitly refers to the date table (called Calendar) and not the fact table):
StkOutCnt:=CALCULATE (
COUNTROWS ( VALUES ( Calendar[DateKey] ) ),
FILTER (
Calendar,
[Stock qty] < [Avg Monthly Sales Qty L12M@SKU]
)
)
Below you can see the sub measures (circled in red) are giving results for all days in the calendar.Highlighted in yellow are dates for which the StkOutCnt measure is not returning a result. Having investigated these blank dates, I am pretty confident that they are dates for which there are no transactions in the fact table (weekends, public holidays etc...).why I am getting an "inner join" with my fact table dates despite the fact that this is not requested anywhere in the dax code and that the two sub measures are behaving normally?
I am working on a model where I have a sales fact table. Each fact record has four different customer fields (ship- to, sold-to, payer, and bill-to customer). I have one customer dimension table that joins to the sales fact table four times (once for each of the customer fields above). When viewing the data in Excel, I would like to have four hierarchies (ship -to, sold-to, payer, and bill-to customer) within Customer.
Is there a way to build hierarchies within my Customer dimension based on the same Customer table? What I want is to view the data in Excel and see the Customer dimension. Within Customer, I want four hierarchies.
I'm using the XML source component with an autogenerated XSD. There's a small error in the XSD definition, the ID column is defined as unsigned short instead of non-negative integer. I've changed this in the XSD file itself, and renamed it but the DTSX package keeps failing with an error that
the id value is to large.
Obviously it's still using the old XSD instead of then new one. How do I fix this?
(The XSD location in the XML component is referring to the correct XSD file)

I ran into a problem using the "sql data source updating " method. i'm using a form view with about 20 parameters that are bind to controls in the form view and 5 other parameters that i'm setting the value to in the "sql data source updating" method. Every thing updates find execept for the last 5 parameters that i'm setting the values to in the "sql data source updating" method. My store procedure(sp) updates and insert mulitple tables. For some UNKOWN reason the tables that uses the parameteres in the "sql data source updating " are inserting multple records when only 1 record should be inserted. Have anyone have this problem?
I am very new to SQL Server 2005. I have created a package to load data from a flat delimited file to a database table. The initial load has worked. However, in the future, I will have flat files used to update the table. Some of the records will need to be inserted and some will need to update existing rows. I am trying to do this from SSIS. However, I am very lost as to how to do this.
Any suggestions?
I only see a need for a PK in a dimension table, not a fact table. Do you agree?
View 4 Replies View RelatedI would like to know how to use a fact table so that when I insert or update a row with a word that the table will reference the fact table to make sure that the word I'm using is correct.
for example I have a table with column Fulltext and Abbreviation
in the fulltext column I have a a word "Windows Server 2008" now in the abbreviation I would like to abbreviate this to "Win Srv 08" Now the Fact table would have to columns Fulltext and Abbreviation under Full text the full words would be in it like Windows, Server, and 2008 and under the Abbreviation column Win, srv, and 08
So I want it so that everytime the word Windows comes up and I need to type an Abbreviation for it that it will reference the fact table which is using the Abbreviation Win. To avoid different ways of abbreviating the word windows.
Is there a way to do this automatically so that I don't have to manually go back and forth between the fact table and the table that I'm updating?
Hi,
we have a problem with "one-to-many relations between fact table and dimension table". Take the example of table "LOGGEDFLAW" which is related one-to-many to the table "LOGGEDREASON. "LOGGEDFLAW" includes the column "FLAWKEY" and "LOGGEDREASON" includes the column "REASONKEY" and essentiallay the column "FLAWKEY" as foreign key. Now assume that we have the following records in there:
LOGGEDFLAW
1) FLAW1
2) FLAW2
LOGGEDREASON
1) REASON1,FLAW1
2) REASON2,FLAW1
3) REASON3,FLAW2
Now assume, that "LOGGEDFLAW" is the facttable and "FLAWCOUNT" is the measure with the source column "FLAWKEY" in which we want to count the number of FLAWs. As you see in the example the number of FLAWs is 1 for "FLAW1" and "FLAW2". Microsoft Analysis Server generates the value of 2 for the number of FLAWs "FLAW1" because of the one-to-many relationship to the table "LOGGEDREASON". In the attached ZIP File you find :
- a MDB File with the described example
- a screenshot from the cube constructed in AS
- a screenshot from the result table generated with AS.
The question: How is it possible to calculate the measure "FLAWCOUNT" correctly, ignoring the records generated by the one-to-many relationship?
Best regards,
Thorsten
I have picked an exmple from this forum, to help me explain my current problem...
"I'm looking for a solution to import data from a flat file into an normalized data modell. To explain it a little simpler think about to following:
The Data Souce is a CSV-File with FirstName, LastName and Category. Sample data could be
Dirk; Bauer; sailing
Peter; Bauer; fishing
Marc; Bauer; reading
In my data modell I have defined the 2 tables "Person" and "Category":
Table "Person"
----------------
[PersonID] [int] IDENTITY(1,1) NOT NULL
[CategoryID] [int] NOT NULL
[FirstName] [nvarchar](50)
[LastName] [nvarchar](50)
Table "Category"
----------------
[CategoryID] [int] IDENTITY(1,1) NOT NULL
[CategoryName] [nvarchar](50)
Now I like to read my first row from the source and lookup a value for the CategoryID "sailing". As my data tables are empty right now, the lookup is not able to read a value for "sailing". Now I like to insert a new row in the table "Category" for the value "sailing" and receive the new "CategoryID" to insert my values in the table "Person" INCLUDING the new "CategoryID".
I think this is a normal way of reading data from a source and performing some lookups. In my "real world" scenario I have to lookup about 20 foreign keys before I'm able to insert the row read from the flat file source.
I really can't belief that this is a "special" case and I also can't belief that there is no easy and simple way to solve this with SSIS. Ok, the solution from Thomas is working but it is a very complex solution for this small problem. So, any help would be appreciated...
Thanks,
Dirk"

Could someone help me creating the dimension table?
Thanks!!
I have a large flat file that comes to me. I first import the flat data in to a SQL table for ease of use. Then i put it into a more permanent table with the proper references to dimension tables. I want to build a dimension table out of information from my flat file. I have a dimension table with columns, [Org Client], and [Client#] where [org client] is the name of the client. Both of these columns appear in my flat file but i want to use only the client# in my permanent table. How extract distinct values of client # and [org client] into a dimension table?
My idea was to select distinct values of client# and use some type of foreach loop to go through each client# and use a query to select the TOP(1) values of [org client] where client# = x. Would this work and if so how do I go about setting this up?
I'm really hoping there is a simpler way than this. Thank you all for your time.

Hi,
I am writing a BI solution for a recruitment company. In their
business, the can be n number of participants from different
dimensions linked to the same fact record. For example, a client can
be sent the CV of 50 candidates. That's my first problem. My second
problem is the variety of dimension participant types for a given fact
record. This results in the need for nullable dimension FK's - which
I'm trying to avoid. For example, consider the following two business
events. In the first one, a candidate fills a job. Easy, we have a
record in the fact table where the fact table has the following
columns: DateKey, EventType, CandidateKey, VacancyKey. No nullable
columns, great. But there are other events that I want to store in
the fact table too. Let's go back to my first example: The client is
sent CV's of 50 candidates in one transaction. So there is one client
linked to the fact, but 50 candidates. So now I need to extend the
fact table and add another column: CandidateGroupKey (which links to
and Intermediate Fact Table). But in this case there was no vacancy
involved. So do I now have to make the VacancyKey column nullable?
That doesn't seem like a good idea...
Or do I have to go for a completely different approach and have
different fact tables instead of just one?
Anyone have any suggestions?
Hi!
can any body tell me how to populate the fact table from base tables.
databse name: bookorder
Realtions:
customer (customerid,l_name,f_name,city, district,country)
cust_order(orderid,orderdate,customerid)
order_detail(orderid,itemno,isbn,quantity)
book(isbn,title,edition_no,price)
author(authorid,name,surname)
book_author(authorid,isbn,authorseqno)
Now populate the datawarehouse name: book_orderdw
having fact table & three dimension tables given below from the above bookorder database
fact table
factsales(customerid,timeid,isbn,unit_price,discount_price,sales_quantity,sales_amount)
dimension tables
dimcustomer(customerid,l_name,f_name,city,district,country)
dimtime(timeid,orderdate,dayofweek, month, year)
dimbook(isbn,title,edition_no,price)
Now I have to populate the fact & dimension tables by writing sql scripts.
Now I have already populated the dimension tables by writing sql script,
But I have to populate the fact table taking into account, here I am facing problem in wriring sql script
(i) unit_price is taken from the book base table with reference to the isbn
(ii) sales_quantity is taken from the order_detail.quantity with reference to table cust_order(via orderid & orderdate)
(iii) discount_price is determined dependent on the quantity. if the quantity > 20 then discount 20 %(i.e discount_price = 0.8 * unit_price). if quantity < 10, no discount i.e normal price. if quantity between 10 and 20, discount 10%. Note that the quantity is determined based on each order of each customer, thus if the same book appears at multiple positions in an order, those positions shall be grouped together. This could happen because the pk of the order_detail table is order_id + item no, not order_id + isbn
(iv) sales_amount is sales_quantity * discount_price

View 2 Replies View RelatedHi, everyone,
l've a fact table DEVICE with following structure,
DEVICE_NAME VARCHAR(50)
DEVICE_DATE DATETIME
DEVICE_NUMBER INT
Where DEVICE_NAME and DEVICE_DATE form a PRIMARY KEY
So l would like to import a text file with same information into this table.
My problem is, text file contains records which will violate my primary key constraint. In that case, l would only insert the record with DEVICE_NUMER not equal to ZERO and discard and log the others.
In case of the records violtae primary key constraints have DEVICE_NUMBER not equal to ZERO, discard both and log it.
So anyone has good suggestion on this?

I have heard from my client that they are facing duplicate data issue on one of the fact table.
Basically there is a view built on fact table and client access the data through the views.
There warehouse is loaded daily through SSIS packages. The duplicate records issue is only when the views are queried during the data loading process. The duplicates are gone when the data load is completed.
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
