Re: hi


PFA for the incremental load,

Binary load:

it's one type of load, it's used replicates the data model of an existing qlikview app into another qlikview app without accessing the original data source, once the model reproduced into another qlikview document then u can try your chart objects. this method much faster than other base qlikview document.

remember below point while doing binary load,

1) this binary load statment should be in the first statement of a load script.

2) you can only perform one binary load per script/qvw (i.e u can't do nested binary load doc.)

3) it won't copy the chart objects of the base document.

let say one exampe,

your have A.qvw is the base document

you can create new document all call that existing document using below script

Binary C:\Docs\A.qvw;

Incremental Loading :

with the help of it u can insert ,update and Delete the Record in the QVD data.

  • For Incremental loading your data should have Date Column>> Last modified
  • Using that Data column u need to create the last modified column &capture the Max(Date) using peek function and Store it into Variable
  • Use the Where Condition in the table were new record are getting fetched //(INSERTING NEW RECORD)
  • Use the Where not exists Condition in the table for updating the already loaded data //(Updating RECORD)

Binary Load:

Loading the QVW file into another QVW File

Binary load should always load first in your script

Can able to use only one binary load

it will copy only the data model not the Dashboard
