CREATE TABLE `shirt` (
   `id` int(11) not null,`name` varchar(32),PRIMARY KEY (`id`)

INSERT INTO `shirt` (`id`,`name`) VALUES 
('1','vneck'),('2','scoop neck');

CREATE TABLE `shirt_size` (
   `shirtId` int(11) not null,`sizeId` int(11) not null,PRIMARY KEY (`shirtId`,`sizeId`),KEY `sizeId` (`sizeId`)

INSERT INTO `shirt_size` (`shirtId`,`sizeId`) VALUES

CREATE TABLE `size` (

我正在用它来查询它

SELECT shirt.name,size.name 
FROM   shirt
       INNER JOIN
          shirt_size ON shirt_size.shirtId = shirt.id
        INNER JOIN
          size ON size.id = shirt_size.sizeId

但是结果表只显示了衬衫的名称,我需要尺寸栏也显示在屏幕上.在FROM部分我穿衬衫,尺码但是出错了.在进一步观察它时,我看到很多人只将第一个表名放在FROM部分.我不知道如何表示size.name列.我究竟做错了什么？
