%field and double quotes use in field, what means this?

[fortaleza40]

Hello Community,

I am new doing scripting in Qlik and in the code i use fieldname AS %fieldname and "fieldname" AS [Fieldname], i suppose % is to not display the field in the report and i don't know the diference between a field with double quotes ("")  and without it, i will like to know to be sure when use this or not, i check documentation and i didn't found about it.

Hello @fortaleza40,

The % symbol in your filed can be used to not display the field if you have the variable HidePrefix set to %. 
EX: Set HidePrefix = '%';
Please check out this video:  https://www.youtube.com/watch?v=zyftjogAhtI.

The double quotes you normally use on filed names with more than one word. EX: "Car Name".
I would recommend you to take a look at the file "Tutorial - Scripting for Beginners" in this help page here.

I hope I could help you with your questions.
Please mark this thread as solved if this is the information you were looking for.

hello 

we use simple cote in setAnalysis '' if your field = 'one Value'

and we use double "" if your field = "Many values" exemple sum({< field1 = "ABC*" >} CA)
