Dear QV community

unfortunately I can not find suitable solution for my problem in the forum.
How can I set variables in the load block ? Thank you!

Here a pseudocode of my intension !

MyTable:

LOAD models,
if( product= 'white', productcode = '7231', productcode='7000' ) as productColor,
price,
quantity

FROM
items.csv (txt, codepage is 1252, embedded labels, delimiter is ';', msq);

</qlikview script>

The short answer is that you cannot set variable values within a LOAD statement. You can, however, interrogate the loaded data after loading and set a variable based on the outcome. For example:

MyTable:

LOAD models,
 productColor,
 price,
 quantity

FROM
items.csv (txt, codepage is 1252, embedded labels, delimiter is ';', msq);

tmp:
LOAD Count(productColor) As WhiteCount
Resident MyTable;

Let productcode = (If(Peek('WhiteCount') > 0, '7231', ''));
...

Drop Table tmp;

Hope that helps
