Integration Services :: Load Incremental Data Into Fact Table When Source Table Not Have Timestamp And Unique Key
Sep 24, 2015
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.

I am looking for a way to load the SQL server table where the source xml file format is not fixed.
It has to dynamically check for the attributes and load into a SQL Server table with changing source xml file format.
The levels of the attribute can change in side the xml tags, the C# code has to parse the file get the attribute name and load the associated value.

i m trying to load this table by running the package,i m truncating the
fact table and loading the fresh data,instaed of this without

Have to create SSIS package for the below requirement:
I have source data in 2 excel files. Data from both these excel files should be loaded to the same single Fact table.
The column names in excel files and table are not same. I have a Reference table which has the column mappings between excel and Fact Table.
I have to refer this Reference Tabel for column mappings, plus i have to add some derived columns (Created_Date) to load the Fact_Table.
I have given a sample data structure below:
Source Data
Excel1_Order.xls
OrderNumber OrderQuantity OrderDate
Order10001 100 01-01-2011
Excel2_Customer.xls
CustomerNumber CustomerName CustomerAddress
[Code] ....
Is there any way to handle this in SSIS?

Hello,
I have developed some packages to load data into "Fact" tables in the data warehouse.
Some packages are OK, other ones not. What is the problem?: some packages load fact tables with lots of "Lookup - Data Flow Transformation" into the "data flow task" (lookup against dimension tables) but they are very very slow, too much slow to be choosen as a solution.
Do you have any other solutions to avoid using "Lookup - Data Flow Transformation"? Any other solution (SSIS, TSQL and so on....) is welcome to speed up the Fact table loading process.
Thank in advance

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.

I would like to know what is the use of business key? Is it necessary to have unique key between source and destination? If no, How can we implement SCD?
PS : My source is CSV files and Destination is Oracle DB?

I have a requirement to load multiple flat files in target table .
I have created the package which used to load files into target table using For each loop container.
But now requirement has been changed now I have to take only those files from table where status="Success" and max JobId. By the query I am to get those records which need to load into table.
Below query I am using to get the files which need to load.
select [JobLogKey],[SrcNm],[DestNm]
FROM [ConfigRep].[dbo].[JobLog]
Where [JobId]=
(Select Max(cast([JobId] as Int)) Jobid
FROM [ConfigRep].[dbo].[JobLog]
Where [JobStat]='Success')
Output:-
JobLogKey SrcNm DestNm
268 H:Data PlatformSource FileClient2LocHGSSpecLocation.txt Location.txt
269 H:Data PlatformSource FileClient1LocHGSSpecLocation.txt Location.txt
I have to load using above 2 files which are under SrcNm. I have created one variable called FileToLoad as Object and mapping to result set of above query. I have create JobId,SrcNm and DestNm variable to catch the record at every loop. I have created 2 For each Loop container
Below screen shot of outer Foreach loop. Till here Its working fine. Inner for each loop container not executing any task under that. How to get it done.

have an excel file which contains lots of sheets. Some of them are named as DW-<day>-<month> (for e.g; DW-1-July). Like this I have sheets for the whole month. I have other sheets too with a different name. I would like to import data from these sheets only (DW ones). Upon my research I have found that this can be achieved via For Each Loop Container.

· If record from Master (Staging table) is null
then do soft delete

Import.csv file looks like,
TABLE_NAME DESC CODE
tab1 table1 A
tab1 table1 B
tab1 table1 C
tab2 table2 D
tab2 table2 E
tab2 table2 G...
First column values are table names which are already exists in target database. Next two columns[Desc],[Code] data gets populate from CSV file to table.
In this scenario, how to load tab1 data into the same table in destination and so on.
Which way will be more standard to accomplish this task? If its a script task using C#, looking for clear script to identify a value changes in the first column.

We are designing a Staging layer to handle incremental load. I want to start with a simple scenario to design the staging.
In the source database There are two tables ex, tbl_Department, tbl_Employee. Both this table is loading a single table at destination database ex, tbl_EmployeRecord.
The query which is loading tbl_EmployeRecord is, SELECT EMPID,EMPNAME,DEPTNAME FROM tbl_Department D INNER JOIN tbl_Employee E ON D.DEPARTMENTID=E.DEPARTMENTID.
Now, we need to identify incremental load in tbl_Department, tbl_Employee and store it in staging and load only the incremental load to the destination.
The columns of the tables are,
tbl_Department : DEPARTMENTID,DEPTNAME
tbl_Employee : EMPID,EMPNAME,DEPARTMENTID
tbl_EmployeRecord : EMPID,EMPNAME,DEPTNAME
How to design the staging for this to handle Insert, Update and Delete.

I have a requirement to take xml file, in case the number of column changes, it should not fail the package, rather it should load the data in destination table. Destination table could be altered separately depending on xml schema by the DB team in production.

I have a stored procedure in that attempts to perform a WHERE NOT EXISTS check to insert new records. If the table is empty, the procedure will load the table. However, an insert does not occur when a change to one or more source fields occurs against an existing record. The following is my code:
declare
@Created_By nchar(50)
,@Created_Date datetime
,@Updated_By nchar(50)
,@Updated_Date datetime
select @Created_By = system_user
[code]....
I expected that when one of the source values of any field in the second WHERE clause changes, that the procedure would insert a new record. Why is this not happening? One other note: I am not 'allowed' to use MERGE.

I need help from you data warehouse / SSIS experts out there! I have a Transaction Fact Table with dollar amounts as the measurements. The grain is one row per transaction. I want to roll this up into a Monthly Periodic Snapshot based on 5 keys. I am having no problem where there is transaction data for each month.
However, the problem I am having is - how do I gracefully insert the Monthly rows for the five keys where there was no activity in the transaction fact table - I am sure there is a slick way to do this with SSIS but I am definitely having a mental block on how to accomplish this. Any help would be appreciated!

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 am new to MDM profisee tool and currently working for Addres verification project for my organization.I wanted to clear my doubts here about Unique Identifer in Stage table and how it works.. Here what i understand till now:
Step 1) I created an Entity using MDM profisee UI and it generated a stage table in MDS database called stg.Address_leaf
Step 2) I have loaded data from external source to MDS stage table using ETL and passed Import type as 2 and Import status id as 0
Step 3) I have run store procudure system generated something stg.udp_Address_leaf to load the model and passed the version name as Version_1, Log flag as '1' and Batch tag as 'Address'
Now my below are my questions:
1) What is the field i can use in MDS stage table to populate my unique intifier value coming from source? (lets say Address_Id is my Unique value for all the records coming from source)
2) Where/how Unique Identifier is useful in this process? Will this be useful in next time load from stage to Model?
3) If i truncate and load my MDS stage table in next run and few earlier records has been updated how it will update those records in Model? will this process (code present in SP) recognize by Unique Identier column present in MDS stage table?

I am having difficulties loading data from a flat file to a SQL Database. I am able to load some data but the rest gets kicked out for the following reasons:
1 – The field is varchar 50 and I would like to convert it to a date field
2 – The field contain periods (.) (Only 1 period in each row)
3 – The field contain blanks (NULLS)
How do I create a derived column that will bypass blanks (Nulls) and remove periods (.) in each row then convert column to a date field in SSIS? Looking for steps to create a derived date column using SSIS (derived task); convert it to a date column (09-19-2015); use functions to redirect the nulls and possibly remove the period (.)?
[b][u]Sample Data[/u][/b]
Column 3 (Varchar 50) Need to convert to date; remove periods, and bypass nulls(blanks)
