參考:http://www.cnblogs.com/lhj588/p/3315876.html

SELECT Date ,

MAX(CASE NAME WHEN '小說' THEN Scount ELSE 0 END ) 小說,

MAX(CASE NAME WHEN '文章' THEN Scount ELSE 0 END ) 文章,

sql和oracle的區別？MAX(CASE NAME WHEN '微信' THEN Scount ELSE 0 END ) 微信

FROM TabName

GROUP BY Date;

CREATE TABLE `tabname` (

`Id` int(11) NOT NULL AUTO_INCREMENT,

sql server mysql？`Name` varchar(20) DEFAULT NULL,

`Date` date DEFAULT NULL,

`Scount` int(11) DEFAULT NULL,

PRIMARY KEY (`Id`)

) ENGINE=InnoDB AUTO_INCREMENT=10 DEFAULT CHARSET=utf8;

sql是什么，INSERT INTO `yaoshi`.`tabname` (`Id`, `Name`, `Date`, `Scount`) VALUES ('1', '小說', '2013-09-01', '10000');

INSERT INTO `yaoshi`.`tabname` (`Id`, `Name`, `Date`, `Scount`) VALUES ('2', '微信', '2013-09-01', '20000');

INSERT INTO `yaoshi`.`tabname` (`Id`, `Name`, `Date`, `Scount`) VALUES ('3', '小說', '2013-09-02', '30000');
