IMPORTANT Is using the underscore, considered upper case, ie needing quotes

[Das Goravani]

Do you have to double quote a field name that uses an underscore, which is a shift key character, upper case, no?

Does that cause the field to need double quotes ?

I’m weeding out all the difficulty early on in my app which is in early stages of course.  I want to fix the naming conventions NOW. 

I removed upper case because it was going into the database and requires so many double quotes everywhere. 

If the underscore is just another upper case letter then I want to part with it as well.
