Tranferring Data From SQL Server In Incremental Way
Jul 30, 2007
Hi All
I have this table which has about 30 thousand records
I want to send all the records everyday at night to the other interface(TIBCO) in form of XML.
I can send all the records at once or maybe 10 records at a time
1. If I make one XML with all the records and send it, its risky as XML would be quite big, also it would be time consuming and would generate a big load on the program(.NET program will create XML). Also, any abnormal error would kill the whole process and we would have to start again
2. Processing 10 or 20 records at a time and then sending the XML(with these 10 or 20 records) and doing this till all the records are sent. If there is any error in between in the program(.NET), the program can start from that step again. Now the problem is how I can keep track of the record number already sent to the other interface
Can someone help?
Thanks

I am trying to transfer data into SQL Server from Excel using DTS.
I get error for a particular field:
Data for Source Column 3('Col3') is too large for the specified buffer size.
I gathered from other resources, that this error is due to some record in the excel sheet for which that particular field is too big.
and it reads only the first 8 records to determine a data type.
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q281517
the fix is to chnage the registry value, as mentioned in the above link. But hat is not an option for me, as that slows down the process a lot.
Does any body else has any other suggestion for this?
I have an idea, that worked, but for that I have to manually insert a record on the top in the excel sheet, with a big size data in that field (which gives problem), and then run DTS, later delete that record.
To automate this idea, I tried to do a DTS from a dummy table (with a record with big data in it) to this excel sheet, but it puts the record at the bottom of the sheet. Is there any way to put this record on the top?
Any help in this regard will be greatly appreciated.
Thanks
Nicky

I created some MDF/LDF in SQL 7.0 containing my DB. After that I did not deatch it from the SQL server 7.0 and physically formatted the H.Drive. SQL Server 7.0 data directory is still on D drive, I just formatted the C drive. Before that NT 4.0 and SQL server 7.0 were running but now I installed WINDOWS 2000 Server and SQL server 2000 on this machine.
Is there any way to access the previous DBs (MDF/LDF) and put it into the SQl server 2000.
Thanking you in anticipation

This problem may appear trivial to you guys but is troubling me since quite some time now! The problem is that I created a website using express studio happily and it worked flawlessly on the local host. Now I want to move it to a remote server and my host created a database name ASPNETDB for me on the server. The problem is that that ASPNETDB database is virtually empty and I want to copy all my tables,stored procedures etc etc(complete database) to the remote ASPNETDB database. How can I do that? In the management studio express edition there is no command available to copy paste all contents of the database to another database. Please help I am quite confused!

We have a legacy database whose data needs to be included in our yet-to-be-built sql 2005 data warehouse. Some of the tables don€™t have any natural candidates for a primary key. (Of course, we also need to add other data to the mix.)
Suppose we load the empty warehouse initially. In following loads we don€™t want to include those records that haven€™t changed from the first load (€œduplicates€?) but we also don€™t want to delete the contents of the entire warehouse because of the load time. Any ideas/best practices how to handle €œincremental updates€? to a warehouse would be appreciated.
TIA,
Bill

I am looking to load data incrementally from staging to spectrum database.
Master = Staging table
Detail = Spectrum table
On below logic
.If record from Detail (Spectrum table) is null
then do insert the record into Spectrum table
set status_flag to 'A' for active
else do update the record (replace all old values with new values)
set status_flag to 'A' for active
end-if
· If record from Master (Staging table) is null
then do soft delete
set status_flag to 'D' for delete
end-if

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.

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 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.Â
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.Â
* Should I implement the same method of deleting last 3 months records and loading them again.Â

I am looking to create a incremental value based on the resulting insert that I am using. There already is another field being used as an identity field. I have a beginning value that I just want to add the row number to for the insert.
insert into lineitem select substring(group_id,4,len(ltrim(rtrim(group_id)))-3) as co_code,
0,0,(case when enddate < cast(month(getdate()) as varchar(10))+cast(day(getdate()) as varchar(10))
then 'Prior' else 'Current' end ),
left(acct_type,2) as bene_type, convert(smalldatetime,left(ltrim(rtrim(eff_date)), 8)),
0,trans_amt,0,0,convert(smalldatetime,left(ltrim(r trim(sett_date)),8)),
ltrim(rtrim(b.fname)) + ' ' + ltrim(rtrim(b.lname)) as payee,0,0,a.ssn,'Y',999+count(*),
(case when isnull(b.location,'') = '' then '' else b.location end) as location
from mbi_tran_temp a
left join enrollees b on a.ssn = b.ssn and
ltrim(rtrim(a.group_id)) = ltrim(rtrim(b.mbicode))
The '999+count(*)' is where I would like to have the incremental value.

I need to load only changed or new data in the final load. Please give me some examples also. I am tryin this from last 2 days as I am totally new to SSIS.

I was wondering if there is a way to schedule a tast that will dump afixed width text file of all the new entries in a table. So if I hada table with likeusername - varchar(20)created - smalldatetimeI could get a weekly feed each week of all the new users in a textfile. I know I could write a script that would go through and do thisby looking at the time stamp, and the last time that the filepreviously ran and get the new dates but I was hoping there was abuilt way to do this. Or perhaps a more elegant solution.Thanks,Charlie

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?

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!

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!
