Giving a custom name for a column in dataframe, Julia

Defining a custom name joining certain previously defined strings like so:

df[:join([Str1,Str2,"_",Str3])] = zeros(length(df[:Str1]))

Returns the following error: 

MethodError: objects of type Symbol are not callable

I understand that join doesn't work like that. Is it possible to convert join([Str1,Str2,"_",Str3]) to a variable?

df[Symbol(join([Str1,Str2,"_",Str3]))]

Does the job.

You can concatenate strings with the star * operator

field_name = "Str1" * "Str2" *"_"* "Str3"

or you can do it with string function

field_name = string("Str1","Str2","_","Str3")
