You don't mention different flavors of relational database, but it looks like you're using MySQL; the standard reserves double quotes for identifiers (eg table or column names) and as far as I know only MySQL allows them for strings. If anyone's trying to run the SQL statements from the article on Postgres or another RDBMS, you'll need to change the double quotes (") to single (').
