If a column name has one or more special characters, you must enclose it in double quotation marks when using it as the value of a syntax element of an ML Engine function, regardless of the value of connector property columnNameHandling. In this context, a special character is any character that is not a letter, digit, or underscore (_).
For example, this column name is enclosed in double quotation marks because it includes a space character:
TargetColumns ('"volatile acidity"')
