From the Reference File:
dual(
s , x )
Forced association of an arbitrary string representations with a given number representation
x. In QlikView, when several pieces of data read into one field have different string representations but the same valid number representation, they will all share the first string representation encountered. The dual function is typically used early in the script, before other data is read into the field concerned, in order to create that first string representation, which will be shown in list boxes etc.
Example:
load dual(string,numrep) as DayOfWeek
inline [string,numrep
Monday,0
Tuesday,1
Wednesday,2
Thursday,3
Friday,4
Saturday,5
Sunday,6];
load Date, weekday(Date) as DayOfWeek from
afile.csv;
The script example will generate a field
DayOfWeek with the weekdays written in clear text. QlikView will for all purposes regard the
field as a numeric field.
