Space character in field name

[K K]

Hello,
I've been struggling to retrieve data from a table whose field name contains ' ' (space character).
I was wondering what would be the correct syntax to do this ?

SELECT * FROM MyTable WHERE MyTable.'First Name' = "Jack"

I'm using mysql++ to execute this line. It keeps giving error because of that 'First Name' (contains space).

What should I put if the field name contains space character ?

Thanks for the help!
