Simple fix on an issue i opened and closed :P .
Use of quotes( " )  on insert/update/delete functions
to avoid error thrown by column names who are reserved keywords
Enabling ANSI_QUOTES mode on sql
The " suppress the error thrown by Database about reserved keywords.
Clarified here:
http://dev.mysql.com/doc/refman/5.6/en/sql-mode.html#sqlmode_ansi_quotes

Tested only on mysql.
