mySql warning messages

[llegrand]

Hi,  In trying to solve another issue I found myself looking at the structure of my DB tables.

I have Server version: 5.6.22 - MySQL Community Server (GPL)  and Server version: 10.0.17-MariaDB-log - MariaDB Server on different servers.   

I see these messages in the Settings table
The column name 'group' is a MySQL reserved keyword.
The column name 'key' is a MySQL reserved keyword.

Seems these are on the restricted usage list for something - so do I have an issue with the versions or can I safely ignore these warnings in my dbTable?

I do get some syntax warnings in my logs,  but they haven't ever seem to cause a failure,  so have ignored them previously. 

thanks
Lee
