IF-ELSE or CASE

[#1]

Hello,

I'm trying to do a preceding load, and it will change the original value to something else.

For example, i have a column of zone in a table, which i need to rename the zone, from AP > Asia, EU > Europe.

I know in vb we normally do CASE, or even IF-ELSE. but is there IF-ELSE in Qlikview?

i did a nested IF-ELSE like this...

if(Geographical_zone='AF', RefzoneCode='EUROPE', (IF(Geographical_zone='AS-PA', RefzoneCode='ASIE', (if(Geographical_zone='NA', RefzoneCode='AMERIQ', (if(Geographical_zone='LA', RefzoneCode='AMERSU', (if(Geographical_zone='ME', RefzoneCode='EUROPE', ( if(Geographical_zone='EU', RefzoneCode='EUROPE') ) ) ) ) ) )))))as RefzoneCode,

doesn't really work. If you have better idea, please share with me?

Thanks.

With QlikView, I try to avoid using these classical if-else statements. Instead, try using the incredible associative power built-in to QlikView.

For example, try adding the following line of code to your script:

LOAD * INLINE [

Geographical_zone, RefzoneCode

AF, EUROPE

AS-PA, ASIE

NA, AMERIQ

LA, AMERSU

ME, EUROPE

EU, EUROPE

];

Once you reload your script with the code above, every record that has a matching Geographical_zone value will now be associated with a corresponding RefzoneCode. No functions or special coding required.

I hope this helps ensure your success.

Best regards,

James

Hi James,

Thanks for your suggestion, ideally, that's the better solution. But due to my db structure in QV, i can't do it that way.

I need this zone to intact with the original table. after that, i'll use the value of this field to create key like (year & - & Zone) as PriKey.

but, or there's a way to do the same with your ideal? i haven't figured it out yet.

By the way, the nested if statement is working by removing the column name in the [then] condition.
