Mysql 创建比较SQL,mysql,Mysql,我有一个定义如下的表： CREATE TABLE `link_clicks` ( `ID` INT(10) NOT NULL AUTO_INCREMENT, `Clicked` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP, `State` VARCHAR(2) NULL DEFAULT '', INDEX `LinkID` (`ID`) ) COLLATE='utf8_general_ci' ENGINE=MyISAM

我有一个定义如下的表：

CREATE TABLE `link_clicks` (
    `ID` INT(10) NOT NULL AUTO_INCREMENT,
    `Clicked` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
    `State` VARCHAR(2) NULL DEFAULT '',
    INDEX `LinkID` (`ID`)
)
COLLATE='utf8_general_ci'
ENGINE=MyISAM

State  Oct 27-Nov 2  Nov 3-Nov 9
AL         13           18
AR         6            14
AZ         18           32

我需要做的是创建一个脚本，在其中我可以输入4个日期，并在前2个日期之间的值旁边列出后2个日期之间的值

有点像这样：

CREATE TABLE `link_clicks` (
    `ID` INT(10) NOT NULL AUTO_INCREMENT,
    `Clicked` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
    `State` VARCHAR(2) NULL DEFAULT '',
    INDEX `LinkID` (`ID`)
)
COLLATE='utf8_general_ci'
ENGINE=MyISAM

State  Oct 27-Nov 2  Nov 3-Nov 9
AL         13           18
AR         6            14
AZ         18           32

最简单的方法是发出两个查询，每个日期范围一个查询：

SELECT state, COUNT(id)
FROM link_clicks
WHERE Clicked BETWEEN firstDate AND secondDate
GROUP BY state
ORDER BY state

此查询应生成在

firstDate

和

secondDate

之间单击的所有状态的列表。如果需要查询始终返回所有状态（即使是在所需时间段内根本没有单击的状态），则需要从

状态

表（如果存在此类表）执行

左JOIN

。

那么问题是什么？查看pivot表更多信息，请@MarshallTigerus。一张桌子能做一个枢轴吗？@MB34我知道你没有理由不能。只要谷歌MySQL数据透视表，你就可以找到你需要的所有信息。马歇尔，你真的很有帮助。我来这里是想知道一些细节，我可以整天在谷歌上搜索，却找不到我想要的东西。谢谢。这个网站的目的是帮助，而不是告诉人们RTFM或谷歌吧！这个问题要求一个参数化的查询。实际上，它没有。您声明需要“创建一个脚本”，而不是一个查询。
