qvd

[hafaneh]

Hello,

i have this qvd with data from 2022 and 2023 and i load it daily to take the daily sales ,
im thinking on just keeping this qvd and create another one ( cuz the data needs to change for the history in the qvd sometimes), so i create new qvd and make it take the new date only and combine it with the old qvd, 

any tips on the best way to do this? or if theirs any better way for doing this? 

also if i can do a """WHERE Upper("Date") = Upper(Num(AddDays(Today(), -1))');  """ in the extranl database when i call it in qlik ? or do it somwhere else?  

...,
"Date"
FROM "test"."XXX_DAILY" ;

-- to make load only one day
