Many if's

gleybson_calyx — Fri, 15 Dec 2017 14:54:05 GMT

Hello people,

I need to create an index from a text field.

so I started doing it like this:

if (index (upper ("Text Neg"), 'GIN'), 'Drink'

if (index (upper ("Text Neg"), 'VODKA'), 'Drink'

if (index (upper ("Text Neg"), 'VODCA'), 'Drink', ...

The problem is that there are a lot of words and when it arrives in about 50 ifs it catches.

I'm using QlikSense nov2017.

Do you have any other solution for me not to use all these if's?

May be with Pick(WildMatch())

Pick(WildMatch([Text Neg], '*GIN*', '*VODKA*', '*VODCA*', ...), 'Drink', 'Drink', 'Drink', ....) ....

I applied that way.

I think I made a mistake.

Pick(

WildMatch("Text Neg",

'*GIN*', '*VODKA*', '*VODCA*', 'Drink', 'Drink', 'Drink')) as Indice,

I think you misplaced on parenthesis

Pick(

WildMatch("Text Neg",

'*GIN*', '*VODKA*', '*VODCA*'), 'Drink', 'Drink', 'Drink') as Indice,

Perfect friend.

It worked. Just one more thing.

for every word I put in "WildMatch" do I have to repaint it in "Pick"?

Example below.

Pick(

WildMatch("Text Neg",

'GIN', 'VODKA', 'VODCA', 'VÓDCA', 'VÓDKA',

'VODIKA', 'VÓDICA', 'VÓDIKA', 'GIM', 'CONHAQUE',

'COMIDA', 'BOLO', 'BOLINHO', 'COMIDA DE PRIMEIRA'

), 'Drink', 'Drink', 'Drink', 'Drink', 'Drink', 'Drink', 'Drink', 'Drink', 'Drink', 'Drink',

'Comida', 'Comida', 'Comida', 'Comida') as Indice,

Yes, or you can do something like this

If(WildMatch("Text Neg",

'GIN', 'VODKA', 'VODCA', 'VÓDCA', 'VÓDKA',

'VODIKA', 'VÓDICA', 'VÓDIKA', 'GIM', 'CONHAQUE'), 'Drink', 'Comida') as Indice

or this

If(WildMatch("Text Neg",

'GIN', 'VODKA', 'VODCA', 'VÓDCA', 'VÓDKA',

'VODIKA', 'VÓDICA', 'VÓDIKA', 'GIM', 'CONHAQUE'), 'Drink',

If(WildMatch("Text Neg",

'COMIDA', 'BOLO', 'BOLINHO', 'COMIDA DE PRIMEIRA'),

'Comida') as Indice

But if you do use Pick, then you will have to repeat Drink for all the matches you make
