The database operations class for VBS,

Data | Database <!--
Frog Frogs recommended: VBS database Operations class, this class implements the usual major database operations, because we are dealing with the database every day, sometimes it is convenient to use such a class, but do not know how practical, because in the performance and error handling has not done a lot of consideration, so do not know how its versatility.
It is even more perfect if someone can add dynamic error handling to the class or optimize performance. PS: This class is also to practice the use of the VBS class.
