Deltaload data into QlikView

Hi,

from a SQL-Database data will be loaded into QlikView. In addition new data will be added on every day/week. It is possible to load only new data’s in QlikView, so a full load isn’t necessary?

Regards
Stefan

Yes, its possible.

Use partial load while uploading data in QlikView.

The answer depends on the nature of the source data and how the history may change over time. QlikView has provided instructions for various scenarios right in the QlikView Desktop help. Look for the content called Using QVD Files for Incremental Load.
