Hello good day,
I would like to know as I can, store data daily in a QVD file, without data being lost the day before.
Example
SQL Select * from clickvtemuco;
STORE Table1 into Tabla1.qvd (QVD);
to reload the new data the previous day day lost
You need to concatenate the QVD based history first
Tabla1:
Load *
from <QVD>;
concatenate (Tabla1)
SQL Select * from clickvtemuco;
STORE Table1 into Tabla1.qvd (QVD);
Then you are always adding. The are more incremental scenarios in the qlikView product help under "QVDs and incremental loads" help topic.
