有了这个查询，我可以数数

Created By  ProductGroup           Count
HNSHAK      MOBILE COMPUTING        13
HNSHAK      STORAGE                 2

询问：

SELECT `Created By`, ProductGroup, COUNT(*) `Count`
FROM tablename
GROUP BY `Created By`, ProductGroup;

现在我想像 MARCH/APRIL 或 04-2013/03-2013 一样计算同一个月，如果有可能我有一个数据库，我想向每个用户显示超过 15000 个条目，请按月计算......

我想要这样的输出

Created By  ProductGroup           Count    MONTH
HNSHAK      MOBILE COMPUTING        1       MARCH
HNSHAK      STORAGE                 2       MARCH


Created By  ProductGroup           Count    MONTH
HNSHAK      MOBILE COMPUTING        2       APRIL
HNSHAK      STORAGE                 1       APRIL

Created By  ProductGroup           Count    MONTH
HNSHAK      MOBILE COMPUTING        1       FEBRUARY

SELECT CreatedBy, Productgroup, COUNT(*) AS Count, DATE_FORMAT(CreateDate, '%Y-%m') AS Period
FROM tablename 
GROUP BY CreatedBy, Productgroup, Period ;

您只需要添加月份/期间组。
