Tianmu: Improved the aggregation capabilities of the decimal data type.
-
Tianmu: Improved the readability of code. The code does not spererate logically, or the variables name can not be understooed by the literal meaning. To refactor code make it more readable to anyone who are the first to read that. For example: Changes int DoGetSomething(); to int GetSomethingXXX();, int GetNoNulls() to int GetNumOfNulls().

Tianmu: The date-related functions (such as DATE_ADD, DATE_SUB) can be queried (DATE_ADD|DATE_SUB) when creating view using the date func.(BUG #342)
