SQL Server 2012 :: Need To Implement Incremental Load In Database

Dec 22, 2013

We need to implement incremental load in database. A sample scenario is, there is a view (INCOMEVW) which is build on top of a query like

CREATE VIEW INCOMEVW
AS
SELECT CLIENTID,COUNTRYNAME,SUM(OUTPUT.INCOME) AS INCOME
(SELECT EOCLIENT_ID AS CLIENTID,EOCOUNTRYNAME AS COUNTRYNAME,EOINCOME AS INCOME FROM EOCLIENT C INNER JOIN EOCOUNTRY CT ON
C.COUNTRYCODE=CT.COUNTRYCODE

[code]...

This is a sample view. As of now there is a full load happening from the source(select * from INCOMEVW) and loads to target table tbl_Income.We need to pick only the delta and load to the target table using a staging. The challenge is,

1) If we get the delta(Insert,update or deleted rows in the source tables EOCLIENT,EOCOUNTRY,ENCLIENT,ENCOUNTRY, how to load the incremental to

single target table tbl_Income.

2) How to do the Sum operation with group by in incremental load?

3) We are planning to have a daily incremental load and thinking to create the same table structure as source with Date and Flag column to identify

the date and whether that source row is an Insert or Update or Delete with the flag. But not sure how to frame something like this view and load to single target with Sum operations.

SQL Server 2012 :: How To Create Staging Table To Handle Incremental Load

Jan 2, 2014

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.

Incremental Load: Lookup

Jan 31, 2008



I am attempting to perform an incremental load, inserting new rows and updating existing rows. I am using a lookup and everything works fine, except when it is the first load of the destination table. As there are no records in the table at all, the lookup fails. I thought of using a rowcount - if the count variable is zero load everything from temporary table to load table, otherwise perform lookup and incremental load.

Can anyone help?

Incremental Load In SSIS

Oct 19, 2006

We are in the process of converting our existing incremental loads from DTS to SSIS.

Currently we get all the data for the past month into temp tables in the warehouse, compare with key fields add the new rows and update changed rows. All this is done using Execute SQL task.

Is there a better way to implement the incremental logic using SSIS any new objects that be used to avoid too much SQL codes? Performance is very important and we do a lot of aggregation after the load for the reports to run faster so that we can meet customer SLA's.

We have around 20 tables that needs to be loaded 4 have large amount of data between 20 and 40 million rows out of which we will be brining over around 100 thousand during each incremental run. The other tables have less than 100,000 rows so does not hurt truncating and reloading the entire table.

Any assistance is appreciated.

Thanks!

SSIS Incremental Load - How Do You Do It?

Apr 29, 2008



Hi everyone. I'm trying to figure out how to run an incremental load into a Staging table.


At this point I'm not trying to Conditional Split it between "New" and "Changed" records... just the load.


The logic in my head says that after each load, you can take the most recent "modified" date/time and store that in an incremental load table. That way, next time you run an incremental load, you just have to look up that "modified" date/time, and only load the source records with a "modified" date/time later than the record in your incremental load table. Does that plan sound feasible?


I think so far my problem is that my source is on an ADO.NET connection, and my incremental load table is on my SQL Server. So when I do my load from the ADO.NET database, I cannot read the data from the incremental load table.


Is my logic flawed?
Any help would be appreciated.


Thank you very much!

How To Implement Alter Database Implement Restrictions On SQL2K ?

Dec 28, 2007

Hi Guyz

it is taken from SQL2K5 SP2 readme.txt. Anyone have idea what to do to implement this ?
Our sp2 is failing. we suspect the above problem and researching it.we are running on default instance of SQL2K5 on win2003 ent sp2

"When you apply SP2, Setup upgrades system databases. If you have implemented restrictions on the ALTER DATABASE syntax, this upgrade may fail. Restrictions to ALTER DATABASE may include the following:

Explicitly denying the ALTER DATABASE statement.


A data definition language (DDL) trigger on ALTER DATABASE that rolls back the transaction containing the ALTER DATABASE statement.


If you have restrictions on ALTER DATABASE, and Setup fails to upgrade system databases to SP2, you must disable these restrictions and then re-run Setup."

thanks in advance.

Power Pivot :: Incremental Load Excel File

Jun 4, 2015

We have build a powerpivotmodel that uses a couple of datasources. The user extracts on monthly base an excel file with 20 samples (randomly) from the model to check some aspects of the input. He can put Yes or No into a column if he agrees or not and fill in a remark field. Next this excel file is loaded back into the powerpivot model (in a nightly batch) and the Yes/No field and the remark field are added to the original data. If the user refreshes his excel sample file from the pivot, the remark and YN field will be filled with the values he added. So far so good. One moth later when he extracts the file for a new month a problem arises. Since the excel file only has data for the new month, when the PP-model is reloaded the data for the previous month will be lost. So we need some sort of incremental load for the excel file. Is that possible and is this the best way to handle this situation?

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.

SQL 2012 :: SSIS MERGE For Incremental Loads

Sep 28, 2015

I inherited an SSIS package that is rather simple. It grabs data from a SQL Query and then loads it into a SQL table. The first step of this process TRUNCATES the destination table and then reloads for the current year. This table has over a million rows and the DB SOURCE that we are pulling from is not in our domain, so one can imagine how long this takes.

This process is working fine, (given the 45 minutes it takes to repopulate data in the DESTINATION table), but what I really need is a way to load only the rows that are NEW and UPDATED. I would also need functionality to DELETE the rows that have been removed (sounds like a MERGE, right?).I tried using MERGE and MERGE JOIN transformations but these transformations seem to be different from the T-SQL MERGE statement. MERGE seems like a slow UNION and MERGE JOIN only seems to work with SELECTS.

SQL Server 2012 :: How To Load Historical Data From Old System Into A New One

Aug 12, 2014

I want to load historical data from an old system into a new one.Thing is, that old system stored dates as Datetime and the new one uses DateTimeOffset.

All data was collected in the same Time Zone... but with the Daylight Saving Time (DST)

The offset is either +04:00 or +05:00, based on the calendar date. To add to the complexity, the rules for DST changed a couple of years ago.

To determine the offset, I'd need to know what was or would have been the server Timezone for each historical date.

SQL Server 2012 :: Bulk Load Data Conversion Error (truncation)

May 15, 2014

Is there a switch I can use to force a bulk insert and if data is truncated, I'm good with that. The truncated data, in this case, is not data I can use anyway if it is long enough to be truncated.

I need to keep the field at VARCHAR(23) and if I expand it, I won't be able to join on it after the file load completes. I'd like the data to be inserted (truncated if need be) and then I'll deal with the records that are truncated after I load the file.

Implementing Incremental Database Backup

Apr 11, 2007

Hi,

I am working on one application, which retrieves data from multiple tables in the database and all the fields retrieved, are exported as an excel sheet. All the export functionality is done through DTS. And the data is retrieved using an SP.

I am supposed to use an "incremental backup" approach here. Means, for the 1st scheduling of the package, all the database dump will be there in excel file. But, after that only fields that are updated/inserted are to be filled in the excel file. Each time, when the dump of the database is taken, the excel file is stored in an archive folder with Date and tiemstamp(e.g. TEST_11_04_2007_15_00_00.xls)

e.g. For the first dump, I get 100 records from the database. Before next execution of the package, 10 rows get inserted and 1 row gets updated. So, on the second time execution of the package, I should populate the excel sheet with those 11 rows only, and not 110 records.

I am not authorised to change the database schema.
So, is there any approach to try out this?

SQLXML Bulk Load Of SQL Server Database

May 2, 2007

I need to update a number of sql server tables, the data sources for these coming from a number of stored procedures.  I want a generic way of getting the data and then passing this data to the tables.I am thinking of doing this for each table:Populating a datasetWriting this dataset to XMLUsing  SQLXML Bulk Load to pass this XML to the database to updateI can create the xml data file by:
dataset.WriteXml("C:data.xml")The problem I have is that the example (http://support.microsoft.com/default.aspx/kb/316005/en-us) I looked at relies on the schema being defined:<?xml version="1.0" ?><Schema xmlns="urn:schemas-microsoft-com:xml-data" xmlns:dt="urn:schemas-microsoft-com:xml:datatypes" xmlns:sql="urn:schemas-microsoft-com:xml-sql" > <ElementType name="CustomerId" dt:type="int" /> <ElementType name="CompanyName" dt:type="string" /> <ElementType name="City" dt:type="string" /> <ElementType name="ROOT" sql:is-constant="1"> <element type="Customers" /> </ElementType> <ElementType name="Customers" sql:relation="Customer"> <element type="CustomerId" sql:field="CustomerId" /> <element type="CompanyName" sql:field="CompanyName" /> <element type="City" sql:field="City" /> </ElementType></Schema>Is there any way I can create the schema 'on the fly' similar to how I did for the data source file.As I could then pass these files to the database:objBL.Execute ("schema.xml","data.xml");
