data base refreshing ?

suppose you have a table :

table:

load *

from source;

//you should store it in a QVD

store table in ...path.qvd(qvd);

once you've done this the first time; comment this and do as follow:

// call the data within your qvd:

table:

load * from yourQvd;

concatenate

load * from source; //this now contains new data after refresh

store table in path.qvd(qvd) //the same qvd file

with that, everytime you do a reload; it will call the qvd (the ancient stored data before refresh) and add to it the new data of the table after the refresh, then store all of it in the same qvd to call again and again.

this is incremental load using qvds; you should take a look at it;

hope this helps
