Use of Variable

[Anonymous]

Good afternoon!

I had been doing my first steps with Qlik Sense this week but I have a error when I use a variable and I don't understand the reason.

I have these variables:

LET numMutues = Count(nomMutua);

LET rangs = Floor(255/numMutues);

And my Load is here:

MutuesRGB:

LOAD ApplyMap('mMutues', "ID", 'No informado') as mutua,

$(rangs) as ValueRanged

FROM  [$(vPathQVD)Mutues.qvd](qvd);

How Can I use the variable into the "Load"?

Thanks for the help!

What error are you getting ?

From quick look though, it appears you are not using a Qlik Sense data connection in your FROM bit, but using the QlikView explicit path method.

None of your displayed variables are used within the load and they won't work in this way either - starting with LET and assigning then an aggregation-function. Here you will find many valuable informations about Variables.

Hi,

I guess what you need is to do this:

SET numMutues = 'Count(nomMutua)'; // SET function defines a string which can be used in the script, you must use single quotes in this case.

SET rangs = 'Floor(255/$(numMutues))'; // dollar sign is needed to exchange the variable name by its content

But you will need to add a GROUP BY statement after FROM in your LOAD script, because you are using the Count() funcion. So something like this:

MutuesRGB:

LOAD ApplyMap('mMutues', "ID", 'No informado') as mutua,

$(rangs) as ValueRanged

FROM  [$(vPathQVD)Mutues.qvd](qvd)

GROUP BY "ID";

I do not completely understand what you want to achieve but hope this helps.
