1.服务器端创建Mysql数据库的时候要讲究 1, 不要加注记(因为我的java程序没有去处理,注记也叫注视) 2、编码为UTF-8
2.利用工具生成.sql文件.需要更改的地方有:
1. SET FOREIGN_KEY_CHECKS=0; 该句需要删除
2. .sql文件定义主键是:
CREATE TABLE `dishes` (
`id` int(11) NOT NULL AUTO_INCREMENT,….. ,PRIMARY KEY (`id`));
在SQLite中只要写int(11) PRIMARY KEY NOT NULL 即可实现autoincrement
3. ENGINE=InnoDB AUTO_INCREMENT=111 DEFAULT CHARSET=utf8 这句话不能要
4. COMMENT (注记) 之后的内容,包括它都不能要
举个例子吧
/*

SET FOREIGN_KEY_CHECKS=0;
-- ----------------------------
-- Table structure for dishes
-- ----------------------------
DROP TABLE IF EXISTS `dishes`;
CREATE TABLE `dishes` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`d_enname` varchar(255) NOT NULL,
`d_name` varchar(255) NOT NULL,
`d_price` float NOT NULL,
`d_image` varchar(255) DEFAULT NULL,
`d_taste` varchar(255) NOT NULL,
`d_cook` varchar(255) NOT NULL,
`d_spiciness` int(11) NOT NULL DEFAULT '0',
`d_calories` int(11) NOT NULL DEFAULT '0',
`d_time` int(11) NOT NULL DEFAULT '0',
`mc_id` int(11) NOT NULL,
`mt_id` int(11) NOT NULL,
`mit_id` int(11) NOT NULL,
`d_ingredients` varchar(255) NOT NULL,
`r_id` int(11) DEFAULT '0',
`version_id` int(11) DEFAULT '0',
`d_content` varchar(255) DEFAULT NULL,
`discount_price` float DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=111 DEFAULT CHARSET=utf8;
红色的部分,包括倒数第三行那个"," 都需要删掉或者修改的。改动以后的结果是:

这样的.sql文件可以使用SQLite Expert 直接导入sql文件(前提是你已经自己创建了一个数据库).
OK,那些表已经完全迁移过来了。
另外,附着我写的关于自动修改该.sql文件代码如下,(注意源文件要改名为test.sql,目标文件为result.sql,放在E盘下,当然自己可以手动去改)
