Answer / bobby

When SET QUOTED_IDENTIFIER is ON, identifiers can be
delimited by double quotation marks, and literals must be
delimited by single quotation marks. When SET
QUOTED_IDENTIFIER is OFF, identifiers cannot be quoted and
must follow all Transact-SQL rules for identifiers. For more
information, see Identifiers. Literals can be delimited by
either single or double quotation marks.
