When I try to use that code to create a similar table on a server running MySQL 5.1.30 I get an error:

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(6) NOT NULL, `FollowupDate` datetime(6) DEFAULT NULL, `SalesRep` char(50)' at line 15
