Hello,
We are using stored Procedures (developed in sql server2008 )for fetching data in qlikview Reports.
Please can anyone tell me how to do incremental load and also storing earlier fetched data.
Hi,
Incremental loading is a big concept, you can found the examples of all types of incremental loading in Qlikview Help file and also in Qlikview reference file.

I tried many examples, but it is not working.
I found some examples where it is picking data directly from the table (means select statement is written direclty in the QV script.). But we are calling stored procedures.
So please help us on that front.
Hi,
Select Statement should fetch only latest data, it should not fetch all the data. For implementing the Incremental load you should have a field like LastModifiedOn, which specifies you date of last modification of the record.
If you use stored procedure your stored procedure should fetch only the latest data, or you need to filter the latest data in qlikview.
For implementing Incremental Load, you have to fetch latest records based on the date field and last reload time.
Now concatenate the existing records in QVD.
For better understanding you can go through this concepts in Help you.
Hope this helps you.
Regards,
Jagan.
Hi,
Incremental load can only happen with stored procedure if there is possibility to pass date to procedure and inside you have compared it.
